Schedule 80s Stainless Steel Pipe ,Large Diameter stainless steel tube pipe

Welded Stainless Steel Piping. Welded stainless steel piping is created by rolling a flat steel plate and welding the seam. After welding this seam, it can be removed from the outside or inside surface of a pipe using a scarfing blade. The weld seam can also be heat treated to make the seam less visible.

ASTM A 312, ASTM A 358 or as rolled and welded. We supply common grades of stainless such as 304/304L and 316/316L in standard pipe sizes and schedules including Sch 5, Sch 10, Sch 40s and Sch 80s.

Nominal Wall Thickness:

• Nominal Wall Tolerance Plus 12.5%, Minus 12.5%
• These do not conform to the American National Standard for Welded and Seamless Wrought Steel Pipe
  (ANSI B 36.10 – 1979)

Minimum Wall Thickness on Inspection:

• The following equation, upon which this table is based, may be applied to calculate minimum wall thicknesses from nominal wall thickness:
  • tn * 0.875 = tm
    Where:
    tn = nominal wall thickness, in. [mm], and
    tm= minimum wall thicknesses, in. [mm]
  • The wall thickness is inch-pound units is rounded to three decimal places in accordance with the rounding method of Practice E29. The wall thickness in SI units is rounded to one decimal place in accordance with the rounding method of Practice E29.
• This table is a master table covering wall thicknesses available in the purchase of different classifications of pipe, but it is not meant to imply that all the walls listed herein are
• necessarily obtainable for the applicable product specification.
