The Braid

When the corrugated hose is subjected to pressure, it tends to open axially. The wire braid is provided to prevent elongation caused by the pressure on the hose. This results in manifold increase in the hose's pressure strength. The braid also provides physical protection against damage to the tube and also dampens secondary vibration movements.

The braid is made of Stainless steel wire conforming to AISI 304/316/321. The angle of lay, wire thickness, number of strands are carefully selected to meet the various application requirements. The braid is woven in such away that line pressure produces braid tension, and correspondingly provides radial and axial constraint prohibiting elongation of inner tubes. Multiple braided assemblies required to accommodate higher pressures, are also available.

Loose braids are also manufactured to meet specific requirements for rubber hoses and other flexible hoses of varied materials. These are tailormade to meet customer needs.

The above pressure ratings are for fluid and ambient temperature of 30 Deg. C.

The burst pressure is 4 times the maximum working pressure.

We also supply hoses with lesser bend radius/higher pressure rating on request.

Testing:

  • All hoses are pneumatically tested.

  • Hydraulic tests are conducted on samples picked at random-grade wise, batch wise.

  • Test certificates for the material and hose are furnished upon request.

The above information is subject to change without notice due to continuous development and research.
