  • Bright Annealing Stainless Steel Tubes High Purity Sanitary Pipes Seamless - China

    price: contact company for price

    Designed for critical and purity applications such as semiconductor

    manufacturing, LSI’s high purity tubing delivery of gases, chemicals

    and solvents, or use in ultra High vacuum piping for reducing out gas

    rate. From advanced manufacturing processes, including special cold

    drawing and cold pilgering, not just precision for sizes, but also

    enhance material substrutes density by cold pilgering process. The ID

    is cold rolling to a 15Ra( 0.4µm) finished, by Hydrogen bright annealed

    process removed tube lubrication and optimum anti- corrosion ability,

    stress free, good mechanical properties follow by precision cleaning

    process to removed any residual contaminants, simulated natural light

    inspection at both ends verifies cleaning before the tubes are nitrogen

    purged and capped.

    Surface Treatment: Bright annealed, polished outside and inside surface, Electronic Polishing.

    Pressure Ratings: Based on using the more conservative Barlow formula where P=( 2TxS) / O

    P=burst pressure T=wall thickness S=tensile strength O=outside diameter.
