ASTM A53 is a carbon steel alloy, which can be used as structural steel or for low-pressure pipelines.
ASTM A53 (ASME SA53) carbon steel pipe is a specification that covers seamless and welded black and hot-dipped galvanized steel pipe in NPS 1/8″ to NPS 26. A53 is intended for pressure and mechanical applications and is also acceptable for ordinary uses in steam, water, gas, and air lines.
A53 pipe comes in three types (F, E, S) and two grades (A, B).
A53 Type F is manufactured with a furnace butt weld or may have a continuous weld (Grade A only)
A53 Type E has an electric resistance weld (Grades A and B)
A53 Type S is a seamless pipe and found in Grades A and B)
Permanent Steel Manufacturing Co.,Ltd has a full range of stock in ASTM A53 steel pipe (ASME SA53 steel pipe).
ASTM A53 Grade B is the material under the American steel pipe standard, API 5L Gr.B is also the American standard material, A53 GR.B ERW refers to the electric resistance welded steel pipe of A53 GR.B; API 5L GR.B Welded refers to the material Welded steel pipe of API 5L GR.B.

ASTM A53 seamless steel pipe is an American standard brand. A53-F corresponds to China's Q235 material, A53-A corresponds to China's No. 10 material, and A53-B corresponds to China's No. 20 material.
Dimensions
Outer diameter: The range is usually between 21.3mm and 762mm. Some data also show that it can be as small as 10.3mm or as large as about 660mm, depending on the manufacturer and actual needs.
Wall thickness: generally 2.0mm to 140mm. Steel pipes with different wall thicknesses will be selected for different application scenarios and pressure requirements.
Dimension tolerance: When the outer diameter of cold-drawn tube is greater than 30-50mm, the allowable tolerance is + 0.3%; when the outer diameter is greater than 50-325mm, the allowable tolerance is + 0.8%. When the outer diameter of hot-rolled tube is 76-168mm, the allowable tolerance is + 1.0%. For wall thickness, when the wall thickness is ≤25mm, the allowable tolerance of cold-drawn tube wall thickness is + 10%, and the allowable tolerance of hot-rolled tube wall thickness is - 10%, +12.5%.
