Stainless steel clean-pipe fittings

316L stainless steel clean‑grade tubing is available in BA bright‑annealed and EP electropolished grades, fully compliant with the ASTM A269 industry standard. The tube's internal surface roughness is precisely controlled; EP‑grade tubing achieves exceptionally low Ra values, effectively minimizing particle release and reducing media residue. It exhibits excellent corrosion resistance and demonstrates stable resistance to intergranular corrosion in welded joints. The product undergoes cutting, cleaning, nitrogen purging, and hermetic sealing in a Class 100 cleanroom, ensuring complete prevention of secondary contamination. It is widely used in semiconductor specialty gases, photovoltaics, biopharmaceuticals, data‑center liquid cooling, and high‑purity fluid delivery applications. Customizable with ferrule‑type and VCR fittings, it comes with material certifications and test reports, supports fixed‑length fabrication, and provides highly reliable, clean‑grade tubing solutions for advanced fluid‑handling projects.

Stainless Steel Clean Pipe Fittings

Stainless steel clean‑grade fittings are manufactured from 316L ultra‑low carbon stainless steel and offer a variety of connection types, including ferrule‑type, VCR, and others, covering a full product range such as straight connectors, elbows, tees, and adapters. They can undergo bright annealing or electropolishing, resulting in exceptionally smooth inner walls with stringent precipitate control, making them ideal for handling ultra‑high‑purity gases and clean fluids. Our products adhere to rigorous clean‑production processes, including degreasing, ultrasonic cleaning, and dust‑free packaging, ensuring stable performance and excellent sealing. They are widely used in clean‑room applications across industries such as semiconductors, new energy, laboratories, and precision manufacturing. We also provide comprehensive selection assistance and technical support, offering one‑stop solutions for clean‑process piping systems.

Stainless steel cleanroom valve, flanged

Stainless steel clean‑room valves are primarily constructed from 316L stainless steel and encompass a range of types, including clean‑room ball valves, needle valves, and diaphragm valves. They support high‑cleanliness surface treatments such as BA and EP, and are compatible with tubing connection methods like ferrules and VCR fittings. The valve flow paths are smooth with no dead corners, offering stringent control over leachables and particulates, along with excellent corrosion resistance, making them ideal for handling ultra‑high‑purity gases and clean liquids. All products undergo clean‑room assembly, leak testing, and ultrasonic cleaning, followed by rigorous inspection before shipment, ensuring compliance with the demanding requirements of cleanroom applications in semiconductors, new energy, precision laboratories, and other fields. We also provide product selection and technical support services, and offer complementary supplies of cleanroom piping and fittings to guarantee precise control and long‑term stable operation of high‑purity fluid lines.
