GANYEAH Steel is supplying stainless steel welded pipes as per ASTM A312 in common grades such as 304/304L and 316/316L in standard pipe sizes

SUS304 Stainless Steel Welded Pipe IN HOUSE TESTING OPTION:

HYDRO TEST UP TO 15000 PSI
All type of Fittings & valves are tested at a specified static pressure for a predetermined period for no leakage.

SOME SPECIAL TEST ON REQUEST OF CLINTS:

PNEUMATIC/GAS TEST
ALL COMPRESSORE AND THREADED FITTINGS and valves are subjected to Pneumatic test at 150psi air pressure and 2000psi Nitrogen pressure. Pneumatic/Gas test is carried out after hydro testing and complete drying of the items following Hydro-Test.

Helium Gas Test (HG-TEST) can be offered on request:

PRESSURE CYCLE TEST
All fittings and valves are tested for pressure cycle test where pressure surges from Opsi to 5000psi. The test is conducted at the rate of 25 to 45 cycles per minute with the digital counter. Client can specify number of cycles and condition of test.

TEMPRATURE TEST ON REQEUST
fittings and valves are heated to temperature upto 350oC for one complete cycle of 4 hours. After that valves are again subjected to Hydro, Pneumatic and Pressure cyclic test for no leakage. All the above test are certified by our own Quality control department and can be witnessed by client or third party inspection company of client's choice.

VIBRATION TEST
fittings and valves are tested for severe vibration under impulse pressure for no leakage
