Pipeline steel refers to a type of steel with special requirements used for the transportation of oil, natural gas and other pipelines. Depending on the thickness and subsequent formation, pipeline steel can be produced by hot continuous rolling machines, furnace coil machines or plate machines, and formed into large-diameter steel pipe by spiral welding or UOE straight seam welding. The current development trend of S420MC alloy steel sheet pipeline engineering is large-diameter, high-pressure rich gas transportation, high cold and corrosive service environment, and thickening of submarine pipelines.

The quality grade symbols of Q235 steel plate are A, B, C and D respectively. Different grades represent different impact temperatures. S420MC alloy steel sheet, Q235A is not required for impact toughness test; Q235B is required for impact toughness test at room temperature (20 ℃); Q235C is required for impact toughness test at 0 ℃; Q235D is required for impact toughness test at - 20 ℃. For the above-mentioned B, C and D grade steels, Akv ≥27J is required under different temperature requirements. At different impact temperature, the impact value is also different.
