    Value-add services

    Stainless Steel Pipe Polishing
    Stainless can polish nearly any stainless steel pipe item to a #4 polish, #6 Polish, #7 polish or a #8 mirror finish. Stainless steel polished pipes can also be cut to size.
    Stainless Steel Pipe Beveling
    Stainless can bevel the edges of stainless steel plate to prepare for welding or other processes.
    Stainless Steel Pipe Honing & Turning
    Stainless can hone pipe and tube, using a precision abrasion process in order to obtain a desired finish or close dimensional tolerance.
    Heatreating & Annealing
    Some grades of stainless steel pipe can be heatreated to change the mechanical properties.
    Positive Material Identification (PMI)
    Stainless can perform PMI testing in house for most stainless steel grades, or we can work with independent labs to complete PMI in order to meet customer specifications.
    UT Testing
    In some cases, UT testing of the stainless steel plates may be required. We can assist you with this requirement.

    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.
