standards and applications:
API 5L X70 welded pipe: This type of welded pipe follows the API 5L standard and is mainly used for oil and gas pipelines. X70 grade welded pipes represent high strength requirements and are suitable for oil and gas transportation that requires higher pressure and diameter.
A252 GR.3 welded pipe: This type of welded pipe follows the A252 standard and is mainly used for industrial pipelines and structural supports. A252 GR.3 is usually used to make pillars for structures such as storage tanks, pressure vessels and bridges.
Manufacturing process:
API 5L X70 welded pipe: Hot rolling or cold rolling process may be used in the manufacturing process, and the cooling process is controlled to ensure that the welded pipe has the necessary mechanical properties and compressive strength.
A252 GR.3 welded pipe: This type of welded pipe usually uses seamless welding technology to ensure the integrity and strength of the structure, and is suitable for structural support that requires high safety.
Performance characteristics:
API 5L X70 welded pipe: Due to its high strength, X70 grade welded pipes can withstand higher pressure and stress, and are suitable for use in harsh external environments and geological conditions.
A252 GR.3 welded pipe: focuses on structural robustness and durability, passing strict tests and standards to ensure stability and safety in various environments.
