QUALITY EQUIPMENTS AND QULITY CONTROL PROCESS
All the valves are executed by good quality control system,reliable inspection tools and well trained QC workers, ARAN people keep the quality as the highest importance to the customers.
The in house quality control equipment facility,which is for the impact test, hardness test,tensile test,chemical composition and mechanical property lab etc.
1. Valve raw material control: Visual and dimension inspection, PMI,Wall thickness, Impact test if by request, NDE like PT,UT,MT,RT.
2. Valve component machine process inspection: dimension check, machined surface and parts material check, special request like NDE test by order request.
3. Valve assembly and performance inspection: Each piece of the valve is under hydraulic and air test the performance inspection according to order standard request.
4. Valve Paint, package and delivery.
GENERAL QUALITY CONTORL PROCESS
Valve raw material control: Visual and dimension inspection, PMI, Wall thickness, Impact test if by request, NDE like PT, UT, MT, RT.
Valve component machine process inspection: dimension check, machined surface and parts material check, special request like NDE test by order request.
PECIAL QUALITY CONTORL REQUEST
The special request for the Impact test, Radio-graphic test RT, Low Fugitive Emission Test,High temperature, Low temperature, Fire Safe can be well done by customer request.
Low temperature Test: the low and high temperature lab facilities to perform low or high temperature tests in accordance with order requirements. The test exposes the valve to a test low temperature Cryogenic test -196 ℃ or high temperature -538 ℃
PMI Equipment. Positive Material Identification Equipment gives quick chemical analysis on incoming raw materials and after assembly, to certify that materials used were produced and assembled in accordance with order.
Penetrate Test Examination:The NDE certified personnel perform PT examination in house after machine or after assembly.
Fire safe Test:Fire Test facilities to perform fire tests in accordance with order requirements. The test exposes the valve to a fire flame at 761 to 980 °C to verify proper seal of the valve.
