Steel N Alloys continually improves the effectiveness of the quality management system (QMS) and sets quality objectives and work plans. Moreover, Steel N Alloys is committed to upgrade the capabilities of its technical and administrative staff through formal training and continuous technical quality awareness.
We have achieved the high quality through the professional competence of the personnel, high working motivation and a service minded attitude. Every single employee of Nexus is responsible for the quality of his/her work.
All Steel N Alloys products are tested in accordance to internationally recognized standards or our own more stringent internal test procedures, which is developed considering the harsh field conditions. In addition to this we also offer specific testing to our client's requirement.
RAW MATERIAL TESTING
All the material used for Manufacturing of fittings and other fabrication jobs are tested for chemical & mechanical properties. The Results are confirmed to meet original material requirement before processing. We are using measuring equipments calibrated by Govt. approved calibration Agencies.
DIMENSIONAL INSPECTION
All type of Flanges and fittings are checked for dimensional accuracy from raw material stage to in process & final product delivery by using calibrated measuring instruments.
MATERIAL TRACEABILITY
All the material used for Manufacturing of fittings, valves and other fabrication jobs are identified & fully traceable from raw material stage to final product.
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
