Construction
Galvanised Steel Concertina Fibre-Packed Construction
Galvanised Steel Concertina Fibre-packed is manufactured from deep drawing quality carbon steel to BS 1449 galvanised.
The tubing is manufactured by winding profiled metal strip into a tube with a deep fibre or cotton-packed squarelock section.
This packed squarelock construction combines the strength of metallic tubing with great flexibility, while the packing helps reduce air loss through the section.
Galvanised Steel Concertina Fibre-packed combines strength and exceptional flexibility with fibre packing that reduces air loss through the section, making it particularly suitable for extraction purposes.
This particular construction provides the best radius of all the metallic tubes within the Whitehouse range.
Extraction – the fibre-packed construction reduces air loss through the section, making the tubing particularly suitable for extraction purposes
Material Handling – suitable for industrial material handling applications requiring strength and flexibility
Protective Casings – suitable for use as a flexible protective metallic casing
Applications Requiring a Tight Bend Radius – the Concertina construction provides the best radius of the metallic tubing types within the Whitehouse range
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
