The stainless steel pipes produced by our factory strictly adhere to authoritative domestic and international production standards, making them suitable for various high-end precision applications and the preferred tubing material for export trade and precision equipment. In terms of national standards, we comply with GB/T 3089-2020 (Stainless Steel Ultra-Thin Wall Seamless Tubes), GB/T 14976-2012 (Seamless Tubes for Fluid Transport), and GB/T 21833-2008 (Precision Seamless Tubes). For export, we adhere to international standards including ASTM A269 (General Purpose Precision Tubes), ASTM A213 (For Boilers/Heat Exchangers), EN 10216-5/DIN 2462, JIS G3463, and ISO 2037 (Sanitary Standard). Our primary export materials are 304/304L and 316/316L, with specifications covering outer diameters of 0.3–8mm and wall thicknesses of 0.05–1.0mm, meeting the customized needs of different customers. 

In terms of product precision, the outer diameter tolerance is controlled within ±0.02–0.05mm, the wall thickness tolerance within ±0.03mm, and the roundness and straightness are stable, perfectly suited for high-end applications such as precision assembly, microfluidic circuits, and medical syringes. The surface is finished with bright annealing (BA) or electropolishing (EP) processes, resulting in a clean and smooth inner wall with Ra≤0.2–0.8μm, free of oxide scale and residue, making it suitable for high-purity gas delivery, food, pharmaceutical, and chromatography applications with stringent cleanliness requirements.

It boasts significant advantages in corrosion resistance and service life. The 316L material contains molybdenum, providing stronger resistance to chloride ion corrosion and withstanding complex environments such as acids, alkalis, salt spray, and humidity. Its service life is 2–3 times longer than copper tubing, and it is less prone to clogging and deformation even after long-term use. It also possesses excellent pressure and high-temperature resistance, capable of withstanding 10–1200 bar pressure and operating stably within a temperature range of -196℃ to 600℃. It is tensile-resistant, wear-resistant, vibration-resistant, and not prone to cracking. In addition, the tubing is easy to cut, bend, flare, and weld precisely, making it suitable for a variety of precision applications such as sensors, medical, electronics, refrigeration, instrumentation, and aerospace, fully meeting the diverse application needs of customers.
