Shanti Hose Industries - Flexible Hoses

Stainless Steel Hose

Specification

B.S.6501

Construction

Hose Material : S.S 304/304L/321/316/316L
Braid Material : S.S 304
Inner Tube : ANNULAR CONVOLUTED CLOSE PITCH,BUTT WELDED S.S. TUBE.
Size Range : 6 MM TO 300 MM
Temperature : 200 DEG.C. TO +700DEG .C

Applications

Stainless Steel Corrugated Hoses Replace the Traditional Rubber & Plastic Hoses, Where extreme temperature or chemically corrosive fluids are encontered.
These hoses are used for correction of minor misalignent, to accommodate reciprocating or Flexing movement, withstand vacuum & to absorb vibrations.

For static pipe work, the bend radius can be reduced considerably.
For extra high pressure, extra braid can be provided. Consult our Technical Department.
For pressure drop estimates of corrugated metal hose, consult our Technical Department.
The above pressure ratings are for fluid at ambient temp. of 20deg.c

Temperature

As the operating temperature of a hose assembly increases, the maximum working pressure of the assembly decreases.

How to use Temperature Corrections Factor Chart?

Determine the maximum operating temperature of the application.
Locate this temperature on the chart and read across to the proper factor.
Multiply this factor times the maximum working pressure as determined from the Hose Specification Chart.
This answer is your maximum Safe Working Pressure at that Elevated Temperature.
