Pipeline steel can be divided into three types: high cold, high sulfur area and submarine laying. According to the development trend, service conditions, main failure forms and failure reasons of oil and gas pipelines, it is required that the pipeline steel A709 Gr 50W carbon steel plate sheet not only has good mechanical properties, but also has negative temperature resistance, corrosion resistance, seawater resistance and hsscc resistance. These pipelines with bad working environment have long lines and are not easy to maintain, so they have strict quality requirements.

Non-destructive flaw detection of steel plates is a test method for inspecting the A709 Gr 50W 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 A709 Gr 50W 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.
