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.
