Construction
Galvanised Steel Concertina Non-Packed Construction
Galvanised Steel Concertina Non-Packed tubing is manufactured from deep drawing quality carbon steel to BS 1449 galvanised.
The tubing is manufactured by winding profiled metal strip into a tube to create a squarelock section.
Unlike the Fibre-Packed Concertina version, this construction is non-packed, providing an extremely flexible metallic tube where high strength and great flexibility are required.
Galvanised Steel Concertina Non-Packed combines strength with exceptional flexibility. Its larger, stronger squarelock construction provides a flexible metallic tube suitable for a range of industrial applications.
Extraction – suitable for flexible extraction applications
Ventilation – suitable for flexible ventilation applications
Suction & Fan Duties – the highly flexible non-packed construction is suitable for suction and fan duties
Material Handling – suitable for industrial material handling applications where strength and flexibility are required
Protective Casings – suitable for use as a flexible metallic protective casing
Maximum Operating Temperature: +500°C
*Please note the diameters listed below are all inside diameters. Please check this before ordering.
Manufacturing tolerances – All metallic tubing is manufactured to ID sizes, tolerances are + 0.5mm, – 0.0mm – up to 76mm ID, + 1.0mm, – 0.0mm – anything over 76mm ID
Frequently Asked Questions About Galvanised Steel Concertina Non-Packed Tubing
What is Galvanised Steel Concertina Non-Packed Tubing?
Galvanised Steel Concertina Non-Packed is an extremely flexible stripwound metal tube manufactured with a large, deep squarelock section.
How is Non-Packed Concertina constructed?
The tubing is manufactured from profiled galvanised carbon steel strip wound into a tube to form a squarelock construction.
What does non-packed mean?
The squarelock section does not contain the fibre packing used within the Fibre-Packed Concertina product, creating a highly flexible non-packed metallic tube.
What is Galvanised Steel Concertina Non-Packed used for?
Typical applications include ducting and extraction, ventilation, suction and fan duties, material handling and protective casings.
How flexible is Non-Packed Concertina tubing?
Whitehouse describes Non-Packed Concertina as an extremely flexible metal hose, particularly suited to industrial applications where high strength and great flexibility are required.
Is Non-Packed Concertina suitable for ventilation?
Yes. Its extremely flexible construction makes it suitable for ventilation, extraction, suction and fan duties.
What is the maximum operating temperature?
The maximum operating temperature is +500°C.
What sizes are available?
The standard technical data covers internal diameters from 51mm to 305mm. Whitehouse can also manufacture intermediary sizes where required.
Are the listed diameters internal or external?
All listed tubing diameters are inside diameters (ID).
Can non-standard lengths be supplied?
Yes. Non-standard lengths can be ordered to suit individual requirements.
What are the manufacturing tolerances?
For tubing up to and including 76mm ID, the manufacturing tolerance is +0.5mm / -0.0mm. For tubing over 76mm ID, the tolerance is +1.0mm / -0.0mm.
