Bright Annealing Stainless Steel Tubes/High Purity Sanitary Stainless Steel Pipes(seamless)

Designedfor critical and purity applications such as semiconductor manufacturing, LSI’shigh purity tubing delivery of gases, chemicals and solvents, or use in ultraHigh vacuum piping for reducing out gas rate. From advanced manufacturingprocesses, including special cold drawing and cold pilgering, not justprecision for sizes, but also enhance material substrutes density by coldpilgering process. The ID is cold rolling to a 15Ra(0.4μm) finished, byHydrogen bright annealed process removed tube lubrication and optimumanti-corrosion ability, stress free, good mechanical properties follow byprecision cleaning process to removed any residual contaminants, simulatednatural light inspection at both ends verifies cleaning before the tubes arenitrogen purged and capped.
Surface Treatment: Bright annealed, polished outside and insidesurface,Electronic Polishing.

Pressure Ratings: Based onusing the more conservative Barlow formula where P=(2TxS)/O
P=burst pressure T=wall thickness S=tensile strength O=outside diameter.
