Product Description

ASME/API/GOST/DIN/En/JIS Seamless and Welded Steel Pipe

Stainless Steel Pipe and Carbon Steel Pipe are the most common type of standard pipe used today. They are part of tubular goods which are manufactured to different specifications and standards. Pipes are sold by "nominal pipe size" in sizes from 1/8" to 72". Two most common types of pipes are Welded Pipe and Seamless Pipe. Both are available in carbon steel and stainless steel. Welded pipe is also called ERW (Electric Resistance Welded) pipe. Most common specification for welded carbon steel pipe is A53. Seamless pipe is made by process that requires no welding. Most common specification for seamless carbon steel pipe is A106 B Steel Pipe. Stainless Steel pipe is made to spec A312. Stainless steel pipe is also available in both seamless and welded configuration. Most common stainless material is 316 and 304.

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.

Grade B 0.30 1.20 0.05 0.045
  • 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
    Products A53 seamless and welded steel pipe is produced in random lengths 16` – 22` or 32` – 44`, in multiple lengths, and in specific cut lengths.
  • Marking Requirements
    Rolled, die-stamped, ink-printed, or stenciled (manufacturer`s option).
    • Manufacturer`s name, brand, or trademark
    • Size and wall
    • Steel grade
    • ASTM A53

Supply Alloy Hot Rolling Seamless Tube,Cold Rolled Seamless Stainless Steel Pipe,Seamless Steel Boiler Pipe.

Seamless stainless pipe is used for applications that require internal pressure within the pipe such as process equipment, water treatment and marine applications. Welded steel pipe is used for structural applications that are exposed to corrosive environments such as marine and external applications. These include handrails, poles and support piping.
