Product Description

Bangdong supplies ASTM A53Seamless Carbon Steel Pipe, Cs Stainless Steel Pipe, ERW Black Alloy Steel Pipes. Seamless mechanical tubing is manufactured from carbon and alloy steels for structural or other mechanical purposes involving machining or heat treating, where close tolerances, smooth finish, or definite physical properties are important factors. Cold Drawn Seamless stocks are generally carried to OD and ID tolerances, except when the ID is less than 50 percent of the OD. The latter sizes and hot finished seamless stocks are carried in warehouse to OD and wall tolerances.

CARBON Steel Pipe

Carbon Steel Pipe

ASTM Specification A53 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.

  • Testing Requirements for seamless and welded API 53 steel pipe
    • Hydrostatic Testing test pressures for plain and threaded and coupled pipe are specified. Hydrostatic pressure shall be maintained for not less than 5 seconds for all sizes of seamless and ERW pipe.
    • Mechanical Tests:
      • Tensile Test: Two transverse tests required on the ERW for NPS 8 and larger, one across the weld and one opposite the weld.
      • Flattening Test: On ERW for NPS 2 and larger, STD and XS wall (not required for XXS pipe)
      • Bending Test (cold): For NPS 2 and under, XS wall and under; for NPS 1-1/4 and under, XXS wall
      Degree of Bend Diameter of Mandrel
      For normal A53 users 90 12 x nom. diameter of pipe
      For Close Coiling 180 8 x nom. diameter of pipe
    • Number of Tests: Seamless and Electric Resistance Weld (ERW) – bending, flattening, tensile on one length of pipe from each lot of 500 lengths, or less, of each pipe size.
  • Permissible Variations for A53 steel pipe
    • Wall thickness: The minimum wall thickness at any point shall not be more than 12.5% under the nominal wall thickness specified.
    • Weights per foot are plus or minus 10%
    • Outside diameter: Outside diameter at any point shall not vary from standard specified more than:
    NPS Over Under
    1-1/2 and smaller +1/64" -1/64"
    2 and larger +1% -1%
  • Lengths of A53 steel pipe

ASTM/ASME A/SA 333 Low Temp

Grades 1/6

The ERW refers to a specific type of welding process that involves both spot and seam welding. Seam welding is commonly used during the manufacturing of round, square and rectangular steel tubing. The steel strip is unwound from coils and side-trimmed to control width and condition the edges for welding. The strip then passes through a series of contoured rollers which cold-form the material into a circular (square or rectangular) shape.
