SS Flexible Hose Pipes / Braided Hose Pipes

Metline Industries is a leading manufacturer and supplier of stainless steel (SS) flexible hose assemblies, also known as flexible metal hose assemblies. We offer a complete range of ss flexible hose pipes from size 1/4” ID to 12” ID in SS 304, 321, 316 & 316L, manufactured in compliance with BS 6501, Part-1. Our stainless steel hose assemblies are available with a wide range of end connections, bore sizes and lengths. We can supply corrugated stainless steel hose assemblies that meets your most demanding technical specifications.

Stainless steel annular corrugated flexible hoses can be supplied with or without stainless steel wire braiding. Wire braiding can be single or double. Generally, an external layer of SS wire braid is provided on corrugated metal hoses, as an unbraided hose tends to elongate axially when pressure is applied. Some customers may even choose two or even three layers of braiding for high pressure applications. The braiding is highly flexible and follows the movement of the hose.

Stainless Steel (SS) Corrugated Flexible Hose Pipes - Construction

Stainless Steel (SS) Corrugated Flexible Hose Pipes – Construction

Stainless steel 304 wires are widely used to manufacture the braid over metal hoses. On customer requests we can also manufacture braids in other stainless steel grades such as SS 321 and SS 316L. Double braided hoses improve the pressure rating of an assembly by at least 30%.

There are two basic types of corrugated metal hoses, which are distinguished by the type of corrugation used during manufacturing: helical or annular corrugation. METLINE metal hoses are manufactured using the annular corrugation method.

SS wire braded flexible hose pipes are used in various industries to carry gases and liquids at elevated pressure or temperatures or high vacuum. A stainless steel hose pipe comprises of an inner hydroformed corrugated thin walled tube which is externally braided or unbraided as per requirements of our customers.

We specialise in the manufacture and export of stainless steel flexible hose pipes, ss wire braded hose pipes, hose assemblies, interlock hose, hydraulic & rubber hose, steel bellows, expansion joints and hydraulic hose fittings.

Stainless steel corrugated flexible hoses offer very high-pressure resistance, vacuum tightness, thermal stability and corrosion resistance.
