ASTM A53

The ASTM A53 standard is one of the most extensively used carbon steel pipe material standards in the oil & gas, structures, constructions, low-pressure plumbing, conveyor rollers, and other process sectors.

ASTM A53 is one of the standards of the American Society for Testing and Materials. The size range for the pipes is from NPS 1/8” to NPS 26”. The wall thickness of the pipes is also mentioned in the standard -astm a53 pipe Schedule 10astm a53 pipe Schedule 20astm a53 pipe Schedule 30, astm a53 pipe Schedule 40astm a53 pipe Schedule 60, and astm a53 pipe Schedule 80. The various types of finishes available for the ASTM A53 pipes are black and hot-dipped, zinc-coated, welded, and seamless.

ASTM A53 Pipe GRADES

ASTM A53 Pipes TYPE e/ f/ s

- ASTM A53 Type F – Furnace-butt welded continuous Welded Pipe

The ASTM A53 Type F Grade A pipe is produced from a continuous coil, and the longitudinal junction is welded by forge welding. Sets of rollers are employed in this procedure to apply mechanical pressure to the heated ends of the coil.

- ASTM A53 Type E – Electric Resistance Welded Pipe.

ASTM A53 Type E Garde A and ASTM A53 Garde B pipes are composed of the continuous coil, and the longitudinal junction is welded by heat generated by electric resistance between the pipe’s opposite ends. A set of rollers is also employed in this operation to unite heated ends. After welding, the weld seam of Grade pipes is heat-treated to a minimum of 540°C.

- ASTM A53 Type S – Seamless Pipe

The extrusion process is used to create ASTM A53 Type S pipes.

The raw steel needed to make pipes is generated using an open-hearth furnace, an electric furnace, or a basic-oxygen process.

ASTM A53 Materials and Manufacturing

1. Seamless and welded pipes can be manufactured by: Flat furnace method/Electric furnace method/Alkaline furnace method
2. E-type or F-type of Grade B steel, after re-welding, the weld should receive at least 1000F [540 degrees Celsius] heat treatment to prevent residual untempered martensite.
3. Pipe expansion: shall not exceed 1% of the outside diameter
4. If a different grade of steel plate is used, it should be well over, the
5. For testing, a specimen of at least 4 inches is required.
6. Product labeling: Manufacturer/Specification No./Dimensions (NPS/Weight Wall Thickness/Specified OD)/Grade (a/b)/Pipe Type (f/e/s)/Experimental Pressure (Seamless Pipe Only)/Non-Destructive Electrical Test (Seamless Only)
7. Galvanized pipe: No uncovered areas, blisters, impurities. No lumps, globular projections or deposits.

Production provides

1. Proof of Compliance: Indicate that the product has been manufactured in accordance with the specifications and that samples have been taken for testing/inspection.
2.Test report: Provide chemical analysis report of the specification
3.EDI, responsible for the submitted report
4.Support tripartite inspection and provide reasonable facilities required to ensure piping specifications.

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.

Application and Usage of ASTM A53 Pipe

- ASTM A53 Pipes for Oil & Gas

ASTM A53 pipes are utilized in a variety of applications, including commodities processing, maritime applications, and oil and gas transportation of gas and liquid. Our clients often request anti-corrosive coating for pipes used to carry oil, gasoline, and propane, and we are happy to provide.

ASTM A53 pipes, which are usually constructed of carbon steel or low alloy steel, are less costly to manufacture than tubing in most cases. In order to determine how much product can flow through the pipe, the interior diameter of the astm a53  pipe is the most important measurement. Pressure rating, yield strength, and ductility are all important characteristics to consider.

- ASTM A53 Pipes for Structural Steel

A wide range of diameters and grades are available, allowing ASTM A53 b/a pipe to be utilized in a variety of different structural applications as well as for a variety of various structural functions. Columns, bollards, sign poles, structural supports, and piling are just a few of the applications for a structural pipe that are common.

- ASTM A53 Pipes for Metallic Conduit

ASTM A53 Pipe metallic conduit pipes are durable steel-based enclosures that are used to route individual electrical wiring conductors throughout a building or structure while protecting the wires from impact, moisture, and chemical vapors. Conduit pipes and electrical metallic tubing (EMT) are also known as EMT.

Conduit pipes are categorized based on the thickness of the walls, the mechanical stiffness of the joints, and the material utilized. Conduit pipes are made of galvanized steel tubes with a wall thickness sufficient to enable them to be threaded. Galvanized rigid conduit pipes (GRC) are a kind of rigid conduit that is threaded. Intermediate metal conduit pipe (IMC) is a lighter-weight, thinner variant of rigid metal conduit (RMC).

The ASTM A53 tubes are hot-dipped galvanized and then blown dry to avoid zinc buildup on the inside of the tubes. On the outside, a clear lacquer is applied to provide a long shelf life. The excellent ductility of the conduit allows for simple bending, threading, and cutting operations.

- ASTM A53 Pipes for Conveyor Roller

ASTM A53 conveyor roller pipes are able to be machined and processed into conveyor rollers. Conveyor roller pipes are components of a conveyor belt that are used to transport products or loose bulk materials such as coal, sand, or iron ore. Conveyor roller pipes are an integral feature of this system and are required for conveyance to be possible.

The conveyor belt transports the goods as it loops around the pulleys and roller pipes. The conveyor pulleys are responsible for driving the belt, maintaining tension on it, and guiding it in the desired direction.  Conveyor roller pipes are responsible for transporting the conveyor belt from one drum to another. They are just used to provide support for the belt
