Seamless steel pipe A53 Gr.A

Description

ASTM A53 Grade A pipe (also known as an ASME SA53 pipe) is intended for mechanical and pressure applications, although it may also be used in general in steam, water, gas, and airlines. It is suitable for welding as well as shaping operations like coiling, bending, and flanging under certain circumstances.

Tianjin Bao Steel Pipe CO.,LTD is a professional and experienced steel pipe supplier and exporter, the largest distributor of TPCO, Baosteel Group and Angang Group, exporting more than 150,000 tons of steel pipes and fittings to more than 150 countries every year. We have a large stock of Seamless steel pipe A53 Gr.A , which can be shipped promptly after you place an order. We also have perfect pipe deep processing capabilities, such as pipe 3PE coating, aluminizing, thermal expansion, U-shape processing, threading, slotting, finning, etc. If you need, welcome to inquire.

TEST & INSPECTION DURING ASTM A53 GRADE A 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 test. 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.
