API 5L GB standard pipes are manufactured according to Chinese national standards, ensuring high quality and reliability for various applications. These standards cover a wide range of seamless steel pipes,GB steel pipes are widely used in various industries due to their strength and durability. Common applications include structural support, fluid transport, boiler and pressure vessels, shipbuilding, and the petroleum and chemical industries.
General-purpose seamless steel pipes (low/medium pressure)
Seamless pipes for boilers (high-temperature/pressure resistance)
Seamless Steel Pipes for Low-Temperature Pipelines and heat exchanger pipes
Covers L245 to L555 grades for oil/gas pipelines.
High-temperature and high-pressure fluid transport
GB standards ensure high quality, safety, and reliability for pipes, meeting diverse industrial needs.
1. Size Standards:
ASTM Pipes: Use British size standards, such as 1/2 inch, 3/4 inch, 1 inch, etc.
GB/T Pipes: Use metric size standards, such as 15mm, 20mm, 25mm, etc.
2. Standards:
ASTM Pipes: Follow standards developed by the American Society for Testing and Materials.
