A53 steel pipe is a kind of carbon steel pipe widely used for transporting water, gas, steam and structural purposes. Due to its good mechanical properties and economy, it holds an important position in construction, infrastructure and industrial systems.

In oil and gas long-distance pipeline projects, API 5L standard is preferred in high-pressure environments because of its higher requirements for chemical composition, mechanical properties and non-destructive testing; In general steam, water, air and structural piping, ASTM A53 occupies a wide range of application scenarios due to its wide coverage of welded and seamless types, low cost and relatively lenient inspection requirements.

API is a standard formulated by the American Petroleum Institute for pipeline systems transporting fluids such as oil, natural gas, and water, covering seamless pipes and welded pipes (including ERW, LSAW, SSAW, etc.).
