    NPS 1/4″ – 30″
    Schedules 10 to 160, STD, XH and XXH

    ASTM A53 pipe is intended for mechanical and pressure applications and is also acceptable for ordinary uses in steam, water, gas and air lines. It is suitable for welding and for forming operations involving coiling, bending, and flanging, subject to certain qualifications.

    Piping Products stocks a full range of A53 pipe (SA53 Pipe) in:

    • Grade B
    • NPS ¼” to 30” diameter
    • Schedules 10 through 160, STD, XH and XXH

    Scope

    ASTM A53 pipe covers Seamless and Welded, Black and Hot-Dipped Galvanized nominal (average) wall pipe for coiling, bending, flanging and other special purposes and is suitable for welding. Continuous-Welded pipe is not intended for flanging. Purpose for which pipe is intended should be stated on order.

    Materials and Manufacture

    The steel for both seamless and welded pipe shall be made by one or more of the following processes: open-hearth, electric furnace, or basic-oxygen. The weld seam of electric-resistance welded pipe in Grade B shall be heat treated after welding.

    Hot-Dipped Galvanizing

    Sets standards for coating of pipe with zinc inside and outside by the hot-dipped process. Weight of coating must not average less than 1.8 oz. per square foot and not less than 1.6 oz. per square foot.


    Permissible Variations in Wall Thickness

    The minimum wall thickness at any point shall not be more than 12.5% under the nominal wall thickness specified.


    Permissible Variations in Weights per Foot

    Plus or minus 10%


    Permissible Variations in Outside Diameter

    Outside Diameter at any point shall not vary from standard specified more than:

    For NPS 1 1/2 and Smaller Sizes For NPS 2 and Larger Sizes
    1/64″ 1/32″ under 1% over 1%under

    Tensile Strength, min., psi 48,000 60,000 45,000
    Yield Strength, min., psi 30,000 35,000 25,000

    Number of Tests Required

    Seamless and Electric-Resistance-Welded — Bending, flattening, tensile on one length of pipe from each lot of 500 lengths or less of a size. Continuous-Weld — Bending, flattening, tensile

    NPS 1 1/2 & smaller NPS 2 & larger
    one / 25 tons one / 50 tons

    Hydrostatic Testing

    Hydrostatic inspection test pressures for plain end and threaded and coupled pipe are specified. Hydrostatic pressure shall be maintained for not less than 5 seconds for all sizes of seamless and electric-resistance-weld pipe.


    Mechanical Tests Specified

    Tensile Test — Transverse required on ERW for NPS 8 and large. Sending Test (Cold) — STD and XS-NPS 2 and under XXS-NPS 1 1/4 and under.

    Degree of Bend Diameter of Mandrel
    For Normal A53 Uses 90 12 x nom dia. of pipe
    For Close Coiling 180 8 x nom dia. of pipe

    Flattening Test — NPS 2 and larger STD and XS. (Not required for XXS pipe.)


    Lengths

    Standard Weight
    Single Random — 16′ – 22′. 5% may be jointers. If Plain Ends — 5% may be 12′ – 16′.
    Double Random — Shortest Length 22′, minimum average for order 35′.
    Extra Strong and Double Extra Strong
    Single Random — 12′ -22′. 5% may be 6′ – 12′.
    Double Random (XS and lighter) — Shortest Length 22′, minimum average for order 35′.
    Lengths longer than single random with wall thicknesses heavier than XS subject to negotiation.

    Required Markings on Each Length

    (On Tags attached to each Bundle in case of Bundled Pipe)

    Rolled, Stamped, or Stenciled (Mfrs. Option)
    Name brand of manufacturer
    Kind of pipe, that is, Continuous Welded, Electric-Resistance-Welded A, Electric-Resistance-Welded B, Seamless A, Seamless B, XS for extra strong, XXS for double extra strong.

    General Information

    Couplings — Applied handling tight. Couplings, 2″ and smaller straight tapped, other sizes taper tapped.
    Thread Protection — Applied to pipe 4″ and larger.
