Flexible Metal Conduit: Galvanised vs Stainless Steel

Flexible metal conduit provides mechanical protection for electrical wiring while allowing cables to be routed around machinery, equipment and installations where rigid conduit may be impractical.

Two common choices are galvanised steel flexible conduit and stainless steel flexible conduit.

Both provide the strength and flexibility associated with metallic conduit, but differences in material, corrosion resistance, temperature capability and operating environment can make one more appropriate than the other.

So, how do you decide which flexible metal conduit to use?

What Is Flexible Metal Conduit?

Flexible metal conduit is a metallic tube designed primarily to protect and route electrical wiring while retaining sufficient flexibility to follow bends, accommodate difficult installation routes and connect equipment.

It is commonly used within:

• Industrial machinery

• OEM machinery
• Areas subject to movement or vibration
• Installations where additional cable protection is required

Flexible conduit can be particularly useful where rigid conduit would make installation or maintenance difficult.

Why Use Flexible Conduit Instead of Rigid Conduit?

Rigid conduit provides excellent cable protection but is not ideal for every installation.

Flexible conduit can make it easier to:

• Route cables around machinery
• Negotiate bends
• Connect moving or vibrating equipment
• Work within restricted spaces
• Accommodate minor misalignment
• Replace or maintain equipment
• Connect machinery to fixed electrical installations

The choice between rigid and flexible conduit should be based on the mechanical and environmental requirements of the installation.

What Is Galvanised Flexible Conduit?

Galvanised flexible conduit uses steel construction with a protective zinc coating.

It provides a combination of mechanical strength, flexibility and cost effectiveness, making it suitable for a wide variety of general industrial and electrical applications.

Whitehouse supplies several forms of galvanised flexible steel conduit, including uncovered and PVC-covered constructions.

For general cable protection in industrial and building-services applications, galvanised steel can provide a practical and economical solution.

What Is Stainless Steel Flexible Conduit?

Stainless steel flexible conduit provides many of the same mechanical benefits while offering greater resistance to corrosion and a wider potential operating environment.

Whitehouse S-DNP Stainless Steel Uncovered Conduit is manufactured from Type 304 stainless steel as standard, with Type 316 stainless steel available by request.

The stainless steel construction can make it particularly useful for applications involving:

• Outdoor environments
• Marine applications
• Food-related environments
• Chemical environments
• Greater temperature requirements
• Conditions where corrosion resistance is important

Material selection should always be based on the complete operating environment rather than simply specifying stainless steel by default.

Galvanised vs Stainless Steel Flexible Conduit

The best choice depends on the application.

Galvanised Steel Flexible Conduit

Typical advantages include:

• Strong metallic cable protection
• Good flexibility
• Cost-effective construction
• Suitable for many general industrial applications

Rather than cutting the conduit, preparing the cable and assembling the components separately during installation, the conduit assembly can be prepared to the required specification in advance.

This can be particularly useful for:

• OEM manufacturing
• Production machinery
• Repeat installations
• Control systems
• Equipment manufacturers
• Applications requiring consistent conduit lengths

Whitehouse offers pre-wired conduit assemblies alongside standard and non-standard conduit lengths.

Don’t Forget the Conduit Fittings

How to Choose the Right Exhaust Clamp

Exhaust clamps provide a simple and effective way of securing sections of exhaust tubing, flexible hose and associated components. However, choosing the correct clamp involves more than simply finding one that looks approximately the right size.

The diameter being clamped, type of tubing, operating environment and required clamping force can all influence which exhaust clamp is most appropriate.

Whitehouse Flexible Tubing supplies a range of exhaust clamps, band clamps and hose clips for industrial and exhaust applications. This guide explains some of the main points to consider when choosing an exhaust clamp.

What Is an Exhaust Clamp?

An exhaust clamp is a mechanical fixing used to secure tubing, pipework or flexible hose at a connection point.

Depending on the application, a clamp can be used to secure overlapping sections of exhaust tubing, connect flexible tubing to another component or help maintain a secure connection within an exhaust or extraction system.

Clamps are available in different constructions and materials, so it is important to select one that suits both the tubing and the conditions in which it will operate.

What Are the Different Types of Exhaust Clamp?

There are several styles of clamp that may be suitable for exhaust and industrial tubing applications.

U-Bolt Exhaust Clamps

U-bolt clamps are one of the most familiar forms of exhaust clamp.

The U-shaped bolt passes around the outside of the tubing and is tightened against a saddle using nuts on each side.

Whitehouse supplies mild-steel U-bolt clamps particularly suited to exhaust applications, with sizes available to suit a wide range of flexible tubing diameters.

They provide a straightforward and cost-effective solution for many general exhaust installations.

Band Clamps

Band clamps use a wider metal strip that wraps around the outside of the tube.

The wider contact area can make a band clamp useful where the clamping force needs to be distributed over a larger section of the tubing.

Whitehouse supplies band clamps manufactured from galvanised mild steel or stainless steel, allowing the material to be selected according to the application and operating environment.

Heavy-Duty Exhaust Clamps

More demanding installations may require a stronger clamping solution.

Whitehouse Stainless Steel Super Heavy Duty Exhaust Clamps use a full-band construction tightened by a bolt and are designed to provide extremely high band tension.

They are particularly suitable for demanding suction and pressure-line applications involving plastic or steel reinforced hose.

What Size Exhaust Clamp Do I Need?

Correct sizing is one of the most important considerations when selecting an exhaust clamp.

The clamp needs to suit the outside diameter of the tube or connection being clamped, rather than simply matching the nominal description of the hose.

For example, a flexible tube may be described by its internal diameter while the clamp needs to fit around its external diameter.

Whitehouse provides reference tables showing the appropriate clamp size for its flexible tubing products.

Before ordering, check:

• The outside diameter of the tubing
• The diameter of the component it is connecting to
• Whether the joint involves overlapping tube
• The available clamping range
• The width and construction of the clamp
• Whether a standard or heavy-duty clamp is required

If you are unsure, provide Whitehouse with the tubing dimensions and application details so the appropriate clamp can be identified.

Stainless Steel or Galvanised Exhaust Clamps?

Material selection depends largely on the operating environment.

Galvanised steel clamps provide a cost-effective solution for many general industrial applications.

Stainless steel clamps may be preferable where greater corrosion resistance is required or where the operating environment is more demanding.

Factors worth considering include:

• Exposure to moisture
• Outdoor use
• Corrosive environments
• Operating temperature
• Frequency of maintenance
• Required service life
• Material of the adjoining components

The most expensive clamp is not automatically the correct one. The material should be selected according to the requirements of the complete installation.

When Should I Use a Heavy-Duty Exhaust Clamp?

A standard clamp is suitable for many applications, but some installations place significantly greater loads on the connection.

A heavy-duty clamp may be worth considering where there is:

• Greater pressure or suction
• Reinforced flexible hose
• Significant vibration
• A demanding industrial environment
• A requirement for increased clamping force
• Larger or heavier tubing
• A connection that will be subjected to regular movement

The hose, tube and clamp should always be considered as a complete connection rather than selecting each component independently.

Can Exhaust Clamps Be Used with Flexible Metal Hose?

Yes, suitable clamps can be used with flexible metal hose and tubing, although the exact clamp will depend on the construction and outside diameter of the hose.

Whitehouse manufactures and supplies a wide range of flexible metallic tubing for exhaust, extraction, ducting and industrial applications, together with clamps and fittings for suitable installations.

When connecting flexible metal hose, it is important to consider the hose construction, outside diameter and the component to which it is being attached.

Exhaust Clamps vs Permanent Connections

A mechanical clamp can provide several advantages compared with a permanently fabricated connection.

These include:

• Easier installation
• Simple replacement of flexible tubing
• Easier maintenance access
• No welding required at the connection
• Ability to dismantle equipment
• Straightforward replacement of worn components

There are also applications where a fabricated or welded connection will be more appropriate.

The choice should therefore be based on the mechanical, sealing and maintenance requirements of the installation.

Choosing an Exhaust Clamp for Industrial Applications

Industrial exhaust and extraction systems can experience vibration, temperature changes and movement during operation.

Before selecting a clamp, consider:

• Tube outside diameter
• Clamp material
• Required clamping range
• Temperature
• Vibration
• Pressure or suction
• Exposure to moisture or corrosive conditions
• Whether the connection needs to be removable
• Required clamping force

For more demanding applications, a wider or heavier-duty band clamp may provide a more appropriate solution than a conventional U-bolt clamp.

Frequently Asked Questions About Exhaust Clamps

What size exhaust clamp do I need?

Measure or confirm the outside diameter of the tubing at the point where the clamp will be fitted. The clamp must suit this outside diameter and provide the required clamping range. Do not assume that the nominal inside diameter of the hose is the correct clamp size.

Are stainless steel exhaust clamps better than mild steel clamps?

Not necessarily. Stainless steel provides greater corrosion resistance and can be beneficial in demanding environments, while mild or galvanised steel can provide a cost-effective solution for many general applications. The correct material depends on the installation.

What is a band clamp?

A band clamp uses a metal strip wrapped around the tubing and tightened to create the required clamping force. Its wider contact area distributes the load across a larger section of the tube than some other clamp designs.

When should I use a heavy-duty exhaust clamp?

Heavy-duty clamps should be considered where greater clamping force is required, such as demanding industrial installations, reinforced hose, higher suction or pressure applications, or connections exposed to significant mechanical loads.

Can exhaust clamps be reused?

This depends on the clamp, its condition and the application. Any clamp that is damaged, distorted, heavily corroded or no longer provides the required clamping force should be replaced.

Can Whitehouse help me select the correct exhaust clamp?

Yes. If you provide the tubing dimensions and details of the application, Whitehouse Flexible Tubing can help identify a suitable clamp from its range.

Food manufacturing and processing environments often require flexible hose to transfer ingredients between machinery, storage and processing equipment. Flour, sugar, grain, cereals and other dry ingredients can present very different challenges from air or water, making it important to select a hose designed for the application.

A suitable food grade hose needs to provide the required food contact compliance while also offering the flexibility, abrasion resistance and flow characteristics needed for regular material transfer.

What Is a Food Grade Hose?

A food grade hose is designed for applications where the hose may come into contact with food products or ingredients.

The construction and materials used need to be appropriate for the intended food contact application. Requirements can vary according to the food being transferred, operating temperature and conditions of use, so the relevant food contact documentation should always be checked before specifying a hose.

Food grade hoses are available for both liquid and dry food applications, including the transfer of powders, flour, sugar and grain.

Choosing a Hose for Flour and Powder Transfer

Flour and other powdered ingredients require careful consideration when selecting flexible hose.

Regular movement of dry materials can cause abrasion to the inside of a hose. A hose used for flour or powder transfer therefore needs to provide suitable abrasion resistance while remaining flexible enough for the equipment and installation.

A smooth internal surface can also help promote efficient material flow and reduce areas where material can collect.

Polyurethane is consequently used in many flexible hoses intended for dry food transfer because it can provide a useful combination of flexibility and abrasion resistance.

Food Grade Hose for Grain and Cereals

Grain, cereals and similar materials can also place significant demands on a hose.

The movement of solid particles through the hose makes abrasion resistance an important consideration, particularly in applications involving frequent or continuous transfer.

When choosing a food grade suction hose for grain, factors to consider include:

• The type of food being transferred
• Internal hose diameter
• Required flexibility
• Abrasion resistance
• Suction or vacuum requirements
• Operating temperature
• Food contact requirements
• Frequency of use

Choosing a hose based purely on its diameter may therefore result in a product that isn’t ideally suited to the complete application.

Why Use Polyurethane Food Grade Hose?

Polyurethane, often abbreviated to PU, is widely used for flexible industrial hose because it can combine flexibility with good resistance to abrasion.

For food handling applications, a polyurethane food grade hose manufactured from suitable materials can be used for transferring a variety of dry food ingredients while retaining the flexibility required for connection to processing and handling equipment.

Whitehouse Flexible Tubing’s Eolo PU Food is manufactured using an ether-based polyurethane wall with a rigid PVC spiral. Its smooth internal surface helps material flow, while the corrugated exterior provides flexibility.

Can the Same Food Grade Hose Transfer Liquids?

Some food grade hoses are suitable for both dry ingredients and liquids, although this should never be assumed.

The intended food product and the manufacturer’s food contact information need to be checked before use.

Eolo PU Food is designed for the suction and transfer of both dry food products and suitable liquids. Typical applications include flour, sugar, grains and animal feed as well as appropriate food liquids.

It is suitable for applicable aqueous and fatty food applications within the conditions stated in its food contact documentation, but it is not recommended for milk or dairy products.

Food Contact Compliance

Food contact compliance should be one of the key considerations when specifying hose for food processing.

Eolo PU Food complies with FDA Regulation CFR 21 Item 177.2600 and EU Regulation 10/2011 for the applicable food classes and stated conditions of use.

Always consult the relevant Food Contact Declaration when assessing a hose for a particular food product or processing environment.

Temperature and Working Conditions

Temperature can affect both the performance of the hose and its suitability for a particular food contact application.

Eolo PU Food has an operating temperature range from -40°C to +80°C, providing a broad working range for food handling and processing applications.

Other factors such as pressure, vacuum, bend radius and the material being transferred should also be considered when choosing a hose.

Choosing the Correct Food Grade Hose

There isn’t a single flexible hose suitable for every food processing application.

For dry ingredients such as flour, sugar and grain, abrasion resistance and material flow may be particularly important. Liquid applications can introduce different requirements, while some installations may require additional properties such as antistatic performance.

Whitehouse Flexible Tubing supplies a range of food grade hoses for different food processing and transfer applications.

Why not consider Stainless Steel Griplock hose?

Flexible metal hose and tubing is used across a wide range of industrial applications where strength, temperature resistance and flexibility are important. From exhaust and extraction systems to material handling and industrial ducting, selecting the correct type of flexible metal hose can have a significant impact on the performance and reliability of an installation.

For demanding environments, stainless steel stripwound hose provides a robust solution capable of combining flexibility with excellent mechanical strength.

What Is a Stripwound Metal Hose?

Stripwound metal hose is manufactured by forming a continuous metal strip into a flexible tubular section. Depending on the construction, the metal strip can be interlocked to produce a strong yet flexible hose capable of accommodating movement and vibration.

Unlike many polymer hoses, a stainless steel flexible hose can be particularly useful where an application involves elevated temperatures, mechanical stresses or the risk of crushing.

Whitehouse Flexible Tubing’s Stainless Steel Griplock uses a fully interlocked stripwound construction to provide flexibility, high mechanical strength and good flow characteristics.

Where Is Flexible Stainless Steel Hose Used?

The versatility of stripwound construction means flexible stainless steel tubing can be found in a variety of industrial environments.

Typical applications include:

• Industrial air ducting
• Smoke and fume extraction
• Exhaust systems
• Dust extraction
• Dry bulk material handling
• Grain handling
• Plastic pellet transfer
• Paper trim extraction
• Protective casing for cables and wires
• Applications involving vibration or movement

The correct hose should always be selected according to the operating conditions and material being conveyed.

Flexible Metal Hose for Exhaust Applications

Temperature is an important consideration when selecting an exhaust or extraction hose.

Many conventional flexible hose materials have limitations when exposed to high operating temperatures. A stainless steel stripwound hose can provide an alternative for applications requiring both flexibility and increased temperature resistance.

Whitehouse Stainless Steel Griplock has a maximum operating temperature of +650°C, making it suitable for many high-temperature ducting, extraction and exhaust applications.

As with any exhaust installation, the complete operating conditions should be considered before selecting a hose, including temperature, diameter, movement and the media passing through it.

Handling Dust and Dry Materials

Flexible metal hose is also widely used for handling dry materials.

Griplock can be used for applications involving materials including ash, dust, grain, paper trim and plastic pellets. Its fully interlocked construction provides good mechanical strength while maintaining the flexibility required by many industrial installations.

Flow direction can be particularly important when conveying abrasive materials. The internal construction of Griplock provides a smoother surface in one direction, so installing the tubing according to the recommended flow direction can help optimise flow and reduce potential damage to both the hose and the material being conveyed.

Managing Vibration and Movement

Not every application involves simply connecting two stationary points.

Industrial machinery can produce vibration, while equipment and ducting systems can experience movement and thermal expansion during operation. Flexible metal tubing can help accommodate this movement while maintaining a connection between components.

Stainless Steel Griplock is particularly suited to applications involving vibration and thermal expansion and can also assist with noise attenuation in suitable installations.

Choosing the Correct Flexibility

The required flexibility can vary considerably between applications.

Stainless Steel Griplock is available with different flexibility characteristics, including Stiff/Stayput, Midflex and Loose/Floppy options on applicable sizes.

Midflex is the standard construction and is suitable for many general applications, while other options can be specified where increased rigidity or greater freedom of movement is required.

What Sizes of Flexible Metal Hose Are Available?

Industrial applications can require anything from small-bore flexible tubing to large-diameter ducting.

Stainless Steel Griplock is available in a comprehensive range of inside diameters, with sizes from 6mm through to 457mm listed as standard. Intermediate diameters and non-standard lengths may also be available for applications requiring a more specific solution.

Finding the Right Flexible Metal Hose

Choosing a flexible metal hose should involve more than simply matching the diameter. Temperature, flexibility, bend radius, media, movement and the operating environment should all be considered.

Whitehouse Flexible Tubing manufactures and supplies flexible metallic tubing for a wide range of industrial applications and can assist with non-standard sizes, lengths and made-to-order assemblies.

Choosing the correct conduit is one of the most important decisions when designing or maintaining an electrical installation. Whether you’re protecting power cables, control wiring or data cables, selecting the right conduit can improve reliability, reduce maintenance costs and extend the lifespan of your installation.

Both flexible conduit and rigid conduit have their place, but understanding the differences will help ensure you choose the most suitable solution for your environment.

What Is Flexible Conduit?

Flexible conduit is designed to protect electrical cables while allowing movement, vibration and easy installation around obstacles. It is widely used in industrial environments where equipment may move or where complex cable routing is required.

Typical applications include:

• Manufacturing machinery
• Robotics
• CNC machines
• HVAC equipment
• Railway systems
• Marine installations
• Automotive production
• Food processing plants

Flexible conduit is available in a variety of materials including galvanised steel, stainless steel and PVC-covered options, allowing it to be selected for different environments and operating conditions.

What Is Rigid Conduit?

Rigid conduit provides maximum mechanical protection and is generally installed in straight runs. It offers excellent impact resistance but requires fittings and bending equipment during installation.

It is commonly used in:

• Commercial buildings
