From Every Part of The tube...
We care about the quality of stainless steel tubes. That’s why we focus on every detail of every component to ensure durability, precision, and superior performance.
Ensures material accuracy and dimensional precision through chemical composition testing (verified by PMI and spectrometer) and size measurement (including OD, WT, length, and pipe end).
Ensures dimensional accuracy and proper fit through ring gauge testing.
Ensures strength and leak-proof performance under specified pressure conditions through hydrostatic testing.
Ensures detection of surface cracks and defects through Penetrant Testing (PT).
Ensures internal surface quality and detects internal defects through borescope (endoscope) inspection.
Ensures surface quality and detects external defects through external surface inspection.
DLSS Never Leaves Problems for Customers to Solve. It’s a Principle We Stand By!
