We are leading manufacturer of Metallic Bellows and Hoses, we have in-house facility to manufacture Hose fittings and machinery for crimping and we also have all necessary machinery to manufacture Metallic bellows.

We deal in BSP,SAE , METRIC,UNEF and customised fittings for hose crimping, we provide parker / Dunlop / indigenous make hose as per our esteem client’s demand.
We also deal in SS corrugated hoses.
Test carried out on hose and hose assemblies.

1) Working Pressure

Hose and fitting selection must be made so that the published maximum recommended working pressure of the Hose and fitting are equal to, or greater than the maximum system pressure. Surge pressures or peak transient pressures in the system must be below the maximum working pressure of the hose assembly. Surge pressures and peak pressures can usually only be determined by sensitive electrical instrumentation that measures and indicates pressures at mili-second intervals. Mechanical pressure gauges indicate only average pressures and cannot be used to determine surge pressures or peak transient pressures.

2) Proof Pressure Test

This test is typically carried out on customer request according to a method defined by the ISO 1402 standard. The test should be made at normal ambient temperature with a proof test bench using water or another suitable liquid. The hose assembly should be pressurised for between 30 to 60 seconds at twice the working pressure of the hose assembly. There should be no leakage or pressure drop.

A complete test report should be provided together with the hose assembly to the customer.

 

3) Hose Bending Radius

The minimum bend radius of a hose refers to the minimum radius that the hose may be bent through whilst operating at the maximum allowable published working pressure. Bending radius is not a measurement or indicator of hose flexibility.  Bending the hose below the minimum bending radius leads to loss of mechanical strength and hence possible hose failure. A minimum straight length of 1,5 times the hose’s outside diameter (D) shall be allowed between the hose fitting and the point at which the bend starts.
