1/4 ”3/4" A-213, Gr.TP316L, BA Stainless Steel Seamless SMLS Aerospace Tube/Tubing
Quick detial
The inner surface of the tube can be bright annealed (BA) or electropolished (EP)
Stainless Steel Clean BA/EP Pipe
Clean tubes are mainly used in high-purity gas production, pharmaceuticals, semiconductors, biology and other
industries that require high cleanliness.
Clean tubes are mainly used in high-purity gas production, pharmaceuticals, semiconductors, biology and other
industries that require high cleanliness. The pipes are produced in accordance with ASTM A269/A270 standards.
For environments with ultra-high cleanliness requirements, the pipes need to be nitrogen purged and packaged
in a clean room to meet the requirements. The inner surface of the tube can be bright annealed (BA) or
electropolished (EP)
