GBT9711 L485/X70 PSL1 LSAW Pipeline

GBT9711 L485/X70 PSL1 LSAW Pipeline, tailor-made for the oil and gas industry, strictly follows the national standard GB/T 9711 and is carefully manufactured using advanced Longitudinal Submerged Arc Welding (LSAW) technology. This technology ensures high precision and quality in the manufacturing process of the pipeline, establishing its leading position in the oil and gas transportation field.

Excellent material properties: L485/X70 pipeline steel, through the fine tuning of the chemical composition, including the base elements of carbon, silicon and manganese, as well as the appropriate addition of strengthening alloying elements of niobium, vanadium and titanium, realizes a significant improvement in mechanical properties. With a yield strength of not less than 485 MPa (or 70 ksi) and higher tensile strength, the material ensures that the pipeline remains robust and reliable in high-pressure environments. At the same time, the material still shows excellent impact toughness at low temperatures (-27℃), providing a solid guarantee for safe operation in extreme environments.

Wide range of applications: With its high strength and excellent welding performance, GBT9711 L485/X70 PSL1 LSAW Pipeline is widely used in the construction of long-distance, large-diameter oil and gas transportation pipelines. It is not only an important bridge connecting oil and gas fields, refineries, gas storage tanks and other key facilities, but also a key infrastructure to ensure energy security and promote economic development.

Exquisite production process and strict quality control: In the production process, advanced longitudinal submerged arc welding technology is used to accurately weld high-quality steel plates into pipelines. The whole process strictly follows the established technology to ensure stable and reliable product quality. At the same time, comprehensive quality control and testing measures are implemented, including chemical composition analysis, mechanical properties testing, non-destructive testing, etc., to ensure that each pipe meets the national standards and customers' requirements, providing worry-free protection for oil and gas transportation.

To summarize, GBT9711 L485/X70 PSL1 LSAW Pipeline plays an indispensable role in the oil and gas industry with its excellent performance, wide range of applications and strict quality control, and is a leader in the field of oil and gas transportation.
