Quality Control Process
Developed over more than four decades of our fabrication experience, our stringent Quality Control
Process serializes and subjects all operations to 100% checks and thorough recording for complete
traceability. We primarily focus on raw materials, welding joint integrity (verified by
radiography/X-rays), dimensional accuracy, and comprehensive assembly pressure testing, concluding
with ID ball Passing and Sponge Cleaning thereafter meticulous painting and packing. We consistently
exceed the requirements of leading material and fabrication codes including ASME, BSS, DIN, VGB,
JIS, NF, GOST, ISO, and EN.
