Details Introduction
Product Overview
API 5L welded pipes are high-quality steel pipes manufactured strictly in accordance with the American Petroleum Institute (API) 5L standard. They are mainly used in the fields of oil, natural gas, water supply and drainage, and industrial fluid transportation. The products adopt advanced welding technology and a strict quality control system, possessing excellent mechanical properties, corrosion resistance, and structural stability. They can meet the needs of long-term safe operation under high pressure, low temperature, and complex geological environments.
Core Advantages
- Standard Compliance ：The entire process follows the latest version of the API 5L standard (such as API 5L-45), covering material grades (B, X42-X100, etc.), dimensional tolerances, mechanical properties, and non-destructive testing requirements, ensuring that product quality meets international standards.
- Diverse Materials ：Low-carbon steel, micro-alloyed steel, and other base materials are optional. Customized material solutions can be provided based on the characteristics of the transported medium, such as sulfur-resistant steel (HIC/SCC testing), low-temperature toughness steel (-40℃ impact energy compliance), etc.
- Advanced Technology ：Utilizing longitudinal submerged arc welding (LSAW), spiral submerged arc welding (SSAW), or high-frequency longitudinal welding (ERW) processes. The welds undergo online ultrasonic testing (UT), eddy current testing (ET), and hydrostatic testing, with welding strength reaching more than 95% of the base material.
- Custom Services ：Supports customized specifications with diameters φ219mm-φ3620mm and wall thicknesses 6mm-40mm. Surface treatments such as 3PE/2PE anti-corrosion coating, epoxy powder internal anti-corrosion, and galvanizing can be provided to meet the needs of different engineering environments.
Application Areas
- Oil and gas long-distance pipeline projects
- Urban natural gas pipeline network construction
- Industrial water circulation systems
- Mine tailings transportation pipelines
- Undersea pipeline projects
