API 5l X65 pipe ISO 3183 L450 PSL2 PSL1 seamless steel line pipe

API 5L X65 pipeline and ISO 3183 L450 PSL2, PSL1 seamless steel pipes are key pipeline materials used for transporting natural gas and oil. X65 and L450 represent the minimum tensile strength of these pipelines, which is approximately 65000 PSI. These pipelines comply with international standards and have excellent corrosion resistance and welding characteristics. PSL2 and PSL1 define the quality control levels for pipeline manufacturing, with PSL2 having stricter requirements, including more rigorous chemical composition and mechanical performance testing.

API 5l X65 seamless steel pipes eliminate the potential weaknesses of welds and provide higher strength and sealing. Carbon steel materials make these pipelines suitable for various environmental conditions, with good plasticity and processability. The diameter range is wide and the wall thickness is diverse, which can meet the needs of different projects and provide support for reliable conveying systems.
