Product Details

Stainless Steel Polylock Hose – Product Details

Stainless Steel Polylock is manufactured from a single stainless steel metal strip, precision-formed around a mandrel to create a fully interlocked section.

A series of flats are built into the hose wall to provide anti-torsion properties. This helps prevent the hose from unwinding when cut, removing the need for tack welding and making the hose easier to process on site.

Key Features

Single stainless steel strip construction
Fully interlocked section
Great flexibility
High mechanical strength
Long service life
Built-in anti-torsion properties
Maximum operating temperature of +650°C
No need for tack welding when cut
Available in a range of internal diameters
Alternative lengths available on request

The Polylock section provides a particularly smooth surface in one direction. For optimum flow characteristics, the media should flow through the tubing in the recommended flow direction.

Following the correct flow direction can help protect both the media and the tubing and can help prevent damage when handling abrasive materials such as plastic pellets.

All listed hose diameters refer to the internal diameter (ID).

Applications

Stainless Steel Polylock Hose Applications

Stainless Steel Polylock is suitable for a range of industrial applications where flexible metal hose is required for the movement, extraction or handling of materials.

Typical applications include:

Conveyance – suitable for conveying materials through flexible metal tubing systems
Ducting & Extraction – suitable for flexible ducting and extraction applications
Materials Handling – suitable for handling and transferring materials

Polylock is also suitable for vehicle and industrial exhaust systems, fume extraction and abrasion-resistant material transfer applications.

Special Features

Polylock Hose Special Features

Stainless Steel Polylock has a series of flats built into the hose wall to provide anti-torsion properties. This helps prevent the hose from unwinding when it is cut.

As a result, there is no need for tack welding after cutting, making Polylock easier to process on site.

Recommended Flow Direction

The design of the Polylock section provides a particularly smooth surface in one direction.

For this reason, Whitehouse recommends that the media travelling through the tubing follows the specified flow direction of the hose.

Following the recommended flow direction provides a number of benefits, including:

Helping to protect the media passing through the hose
Helping to protect the tubing itself
Providing optimum flow characteristics
Helping to prevent damage to the media or tubing when handling abrasive materials

This is particularly important when the hose is used with abrasive materials such as plastic pellets.
