Heavy steel plate is flat-rolled plate supplied in thick sections for load-critical fabrication, where acceptance is driven by through-thickness integrity, thickness/flatness control, and verified properties (strength, toughness, and Z-direction performance when required) that must remain consistent after cutting, forming, welding, and NDT. In project packages, heavy steel plate is treated as a starting material for […]

Differences of ASTM A53 B and ASTM A106 B. ASTM A53 B covers ERW, Seamless and Galvanized steel pipe. A106 B covers only seamless steel pipe for high temperature service.

Heat treatment methods for carbon and alloy steel pipe includes normalizing, annealing, tempering, quenching. It will improve the material performances.

BS EN 10204:2004 is British Standard that related to different types of inspection documents for steel metal products. There are 4 types for EN 102024, 2.1, 2.2, 3.1 and 3.2, the later two types are the mostly used in steel pipe and plates products, so here we will mainly introduce the major differences between two […]
