Round Sanitary Stainless Steel Pipe 2B Finish 3-A 72-03 316L Stainless Steel Tubing

Sanitary Stainless Steel High Pressure Pipe 2B Finish, 3-A 72-03, Pharma-Grade, CIP Systems

Sanitary Stainless Steel High-Pressure Pipes (2B Finish) by Jiangsu China Steel Union Industrial Co., Ltd are precision-engineered for ultra-hygienic applications in pharmaceutical, biotech, and food-grade CIP (Clean-in-Place) systems. Compliant with 3-A 72-03 standards, these electropolished 316L stainless steel pipes feature a smooth 2B surface finish (Ra ≤0.5µm) to eliminate microbial harborage and ensure compliance with FDA, EU GMP, and WHO Annex 1 requirements. Designed for pressures up to 100 bar, the seamless construction and orbital welding compatibility guarantee leak-free performance in high-purity water, sterile media transfer, and aggressive CIP/SIP (Steam-in-Place) cycles. Ideal for aseptic processing, these pipes resist corrosion from acidic/alkaline detergents, alcohols, and high-temperature steam (up to 130°C).
