API 5LGB /ASTM A106B/ASME A53 GB

ASME A53 refers to the American Society of Mechanical Engineers (ASME) standard for seamless and welded carbon steel pipes. It specifies the requirements for various grades of carbon steel pipes suitable for use in pressure and mechanical applications. The A53 standard covers both black and hot-dipped galvanized pipes. These pipes are commonly used in industries such as oil and gas, water transmission, and structural applications.

Seamless carbon steel pipes are made from steel ingots or solid billets that are perforated into tubes, and then hot rolled, cold rolled, or cold drawn. Seamless carbon steel pipes play an important role in China’s steel pipe industry.
