Our premium Seamless and Welded Stainless Steel Pipes are engineered to meet the most rigorous industrial standards, including ASTM A312. Available in a comprehensive range of grades such as 301, 303, 304, 304L, 316, 316L, 310s, 321, and 309s, these pipes provide exceptional corrosion resistance and structural integrity for demanding environments. Whether for chemical processing or automotive structures, our piping solutions ensure long-term reliability and peak performance.
Combining advanced manufacturing techniques with strict quality control, our products undergo bright annealing and precise polishing to achieve surface roughness under 0.3μm. By sourcing raw materials from industry leaders like Taigang and Baogang, and adhering to ISO 9001:2015 and PED 2014/68/EU certifications, we guarantee full material traceability and superior mechanical properties for every batch delivered globally.

For chemical equipment, we recommend Grade 316 or 316L due to the addition of molybdenum, which provides superior resistance to chlorides and corrosive chemicals compared to Grade 304.
Yes, our pipes are certified by AD 2000-W0 and PED 2014/68/EU, and undergo rigorous hydraulic and airtightness testing to ensure safety in high-pressure environments.
Seamless pipes are extruded and have no weld seam, making them ideal for extreme pressure. Welded pipes are formed from strips and welded; we ensure these have high-quality beads and NDT inspection for maximum reliability.
Absolutely. We offer comprehensive processing services including precise cutting, bending, and punching based on your technical drawings.
Our tubes undergo bright annealing and internal weld bead removing, combined with individual plastic sleeve packing and capped ends to keep the bore crevice-free and clean.
Our general MOQ is 1 Ton, but we strive to be flexible. Please provide your specific dimensions and material grade for a tailored quotation.
