The exported stainless steel pipes are made of TP317L ultra-low carbon austenitic stainless steel, with precise specifications ranging from 33.4mm to 127mm in outer diameter, 2.77mm to 3.38mm in wall thickness, and 6000 to 6300mm in length, fully meeting the stringent dimensional accuracy requirements of US industrial projects. The products are manufactured entirely in accordance with ASTM A312 standard (Specification for Seamless and Welded Austenitic Stainless Steel Piping), the authoritative benchmark in the global stainless steel piping industry. This standard covers multiple core indicators, including chemical composition, mechanical properties, dimensional tolerances, and non-destructive testing, ensuring the safe and stable operation of the pipelines under complex conditions such as high pressure and corrosion. Verified by a third-party testing agency, the key mechanical properties of this batch of pipes, such as tensile strength, yield strength, and elongation, all exceed the standard requirements. The weld quality has passed X-ray flaw detection, fully complying with US market import compliance standards.
