Detail Specifications

Hydrostatic Test Station is a way in which pressure vessels such as Gas Cylinders, Pipeline, Gas Handling Systems can be tested for strength and leaks. Vessel is filled with a fluid, mostly water and pressurised using a hydraulic pump to the specified test pressure.

We offer two types of test stations:

• Water Jacketed type cylinder testing
• Conventional (Direct Expansion) type cylinder testing

Water Jacketed Cylinder Testing:

• Cylinder is filled with water enclosed in a test jacket filled with water.
• Cylinder is then pressurised and letting to expand.
• Total expansion is determined by the measuring the quantity of water displaced when under pressure.
• Permanent expansion is determined by measuring the quantity of water to be replaced after release of pressure.

Conventional type Cylinder Testing:

• Volumetric expansion will be determined in this method.
• Cylinder is filled with a known quantity of water, then a known quantity of water is pressurised until the test pressure.
• Permanent volumetric expansion will be determined when cylinder under pressure.
• Total volumetric expansion will be determined after the pressure is released.

Both the systems are approved by CCOE/PESO for Hydro Testing of Seamless Cylinders.

• Robust pumps, Heater and Blowers are used.
• A fully equipped Hydraulic Test Pump, with Safety Relief Valve, Pressure Gauge, Non-Return Valve, Suction Filters and Air Trap.
• A rugged Cylinder Vice for Valving and de-valving of cylinder valve.
• Test lamp for internal inspection.
• A Digital Weighing Scale, Ultrasonic Thickness Gauge for enhanced results.
• An experienced engineer will be deputed to train, guide and commission the system at your works.
