erw carbon steel pipe

ASTM A53 pipe grades range fromSchedule 10 through Schedule 80, with different grades varying in wall thickness, tensile strength, and pressure rating. 

Schedule 10 is the thinnest wall thickness and is primarily used for light-duty applications, while Schedule 80 is the thickest wall thickness and is designed for high-pressure piping systems

ASTM A53 pipe is typically made from carbon steel, although other alloys may be used depending on the application requirements. The pipe is available in both seamless and welded configurations, with diameters ranging from 6 mm to 610 mm (0.25 in to 24 in). Pipe lengths can vary depending on the application requirements and material type.

CHEMICAL COMPOSITION OF ASTM A53 PIPES

ASTM A53 pipe is typically made from carbon steel, although other alloys may be used depending on the application requirements. The pipe is available in both seamless and welded configurations, with diameters ranging from 6 mm to 610 mm (0.25 in to 24 in). Pipe lengths can vary depending on the application requirements and material type.

TEST & INSPECTION DURING ASTM A53 PIPE PRODUCTION

  • Chemical Analysis – Number of tests: 2 pieces each lot of 500 or 2 pieces per heat. (If either pipe fails, an additional two pieces from the same batch must be tested.)
  • Tensile Test – This test is performed to assess the mechanical properties of the pipe. In the case of welded pipe, the weld strength shall not be less than the pipe body strength.
  • Bending Test – On pipe diameters NPS 2 and less, a bending test is performed to determine the ductility of the pipe. The bend test could be 90 degrees or 180 degrees, depending on the situation.
  • Flattening Test – For ductility, pipe sizes greater than NPS 2 are flattening tested. In line with ASTM A53, a pipe sample is sliced and flattened between two flat surfaces.
  • Hydro-Test – This is a test that is performed on each length of the pipe to determine whether or not there is a leak. The pressure must be maintained for at least 5 seconds.
  • Weld Seam Ultrasonic or Electromagnetic Test – This non-destructive test is performed throughout the whole length of the weld to check the weld’s integrity.
