HPI Pressure Tight Stripwound Metal Hose
Description
Pressure-tight technical hose made by helically winding a pre-formed metal strip into a fully interlocked hose and inserting into the lock section a high temperature composite packing for fluid tightness.
Principal Applications
Conveyance of corrosive fluids, bitumen, oxygen, steam, abrasive and pulverised products. HPI is a strong robust hose.
Standards
Manufactured to the specifications where applicable of ISO 15465 Type DOP.
Pressure Capability
The nominal working pressure stated has a safety factor to burst pressure of 3:1. The burst pressure is measured with the hose being straight and motionless under internal hydrostatic pressure at ambient temperature.
Materials of Construction and Temperature
Galvanized steel
Stainless Steel AISI 304
Composite packing - up to +200°C - service life of the hose reduces significantly at elevated temperatures above 200°C
Fitting Attachment
We strongly recommend the use only of packed on reattachable fittings if hose is to be used for liquid use. Welding of this hose is not recommended as the welding process could damage the packing in the hose creating a leak path.
Supply Lengths - standard
19-150mm9, 15 metes
175-200mm9 metes
Longer lengths available on special order.
