GBT9711 L485/X70 PSL1 LSAW Pipeline Production

GBT9711 L485/X70 PSL1 LSAW Pipeline is a pipeline product widely used in the fields of oil, natural gas, etc. The following is a detailed description of its manufacturing process and advantages:
Manufacturing process:
Plate preparation: Select L485 or X70 steel that meets the GBT9711 standard, cut and process it, and prepare the required plates.
Forming: Through the straight seam submerged arc welding (LSAW) process, align the edges of the plates, weld and form them to form a straight seam pipeline.
Welding: Use advanced welding technology to ensure the quality and strength of the weld. During the welding process, strictly control the welding parameters to ensure the stability of the welding quality.
Non-destructive testing: Perform non-destructive testing on the welded pipeline, such as ultrasonic testing, radiographic testing, etc., to ensure that the pipeline is defect-free.
Heat treatment: Heat treatment is performed on the pipeline as needed to improve its performance and organizational structure.
Anti-corrosion treatment: In order to extend the service life of the pipeline, the pipeline is treated with anti-corrosion treatment, such as coating anti-corrosion paint, etc.
Advantages:
High strength: L485 and X70 steels have high strength, which enables the pipeline to withstand high pressure and load, and is suitable for high-pressure transmission systems.
Good welding performance: The straight seam submerged arc welding process can ensure the quality of the weld and improve the sealing and reliability of the pipeline.
High dimensional accuracy: The manufacturing process of LSAW Pipeline can ensure the dimensional accuracy of the pipeline and reduce the installation error of the pipeline.
Good corrosion resistance: Through anti-corrosion treatment, the pipeline can effectively resist the erosion of corrosive media and extend its service life.
Safe and reliable: The pipeline undergoes strict quality control and testing during the manufacturing process to ensure its safety and reliability and reduce operating risks.
High transmission efficiency: Due to the smooth inner wall of the pipeline and low resistance, it can improve the transmission efficiency of the fluid and reduce energy consumption.
Strong adaptability: LSAW Pipeline is suitable for various terrains and environmental conditions and can meet the needs of different projects.
In summary, GBT9711 L485/X70 PSL1 LSAW Pipeline has been widely used in oil, natural gas and other fields with its advanced manufacturing process and excellent performance advantages.
