Pipeline steel ASME SA283 carbon steel plate sheet refers to the hot rolled coil plate or wide thick plate used to transport oil, natural gas and other large-diameter welded steel pipes. In the process of using pipeline steel, it is required not only to have high compressive strength, but also to have high low temperature toughness and excellent welding performance. Pipeline steel plates are used to make oil and gas pipelines. The main ASME SA283 carbon steel plate sheet pipeline steel grades are API 5L grade B, API 5L X42, API 5L X60, API 5L X65 and so on.

Non-destructive flaw detection of steel plates is a test method for inspecting the ASME SA283 carbon steel plate sheet surface and internal quality of the inspected parts without damaging the working state of the workpiece or raw materials. Commonly used ASME SA283 carbon steel plate sheet steel plate flaw detection methods include: X-ray flaw detection, ultrasonic flaw detection, magnetic particle flaw detection, penetration flaw detection, eddy current flaw detection, gamma-ray flaw detection, fluorescent flaw detection, color flaw detection and other methods. Physical flaw detection is non-destructive flaw detection without any chemical changes.

The chemical composition difference between ASME SA283 carbon steel plate sheet, Q235B and 20# steel is as follows: The chemical composition of 20# steel: C: 0.17-0.23%, Si: 0.17-0.37%, Mn: 0.35-0.65%, Cr: ≤ 0.25%, Ni: ≤ 0.30%, Cu: ≤ 0.25%. Chemical composition of Q235B steel: C: ≤ 0.20%, Si: ≤ 0.35%, Mn: ≤ 1.40%, P: ≤ 0.045%, S: ≤ 0.045%. The difference of mechanical properties between ASME SA283 carbon steel plate sheet, Q235B and 20# steel is as follows: The mechanical properties of 20# steel: tensile strength 410 MPa; yield strength 245 MPa; elongation after fracture: 25; reduction of area: 55; no impact. Q235B steel mechanical properties: tensile strength 370-500 Mpa; yield strength: ≥ 235 Mpa; elongation after fracture: 25; impact absorption energy: 27J.
