Pipeline steel plate is a high-strength steel material specially developed for oil, gas and energy transportation projects. China pipeline steel grades are widely used in the fabrication of transmission pipelines, pressure pipeline systems and energy infrastructure due to their excellent strength, toughness and weldability.

    CEHE STEEL supplies a wide range of Chinese pipeline steel plates, including L245, L290, L320, L360, L390, L415, L450 and L485, manufactured according to GB/T 21237 and related international requirements. These grades are commonly used as base materials for oil and natural gas pipelines, with performance comparable to widely used API 5L grades such as Grade B, X42, X46, X52, X56, X60 and X65.

    With stable supply from qualified Chinese steel mills, CEHE STEEL provides pipeline steel plates in various thicknesses, widths and delivery conditions. We support customized sizes, mill test certificates (MTC), third-party inspection and export packaging to meet the requirements of global pipeline fabrication companies, EPC contractors and energy projects.

    Pipeline steel plate is mainly used to manufacture pipes for transporting crude oil, natural gas, refined petroleum products, water, and other fluids. It is also used in pipeline fittings, pressure components, and energy infrastructure projects where high strength and reliable weldability are required.

    Although both are carbon steels, pipeline steel is produced to meet stricter requirements for strength, toughness, chemical composition, and weldability. It is specifically designed for pressurized pipeline systems, while structural steel is primarily intended for buildings, bridges, and general construction.

    The appropriate grade depends on several factors, including operating pressure, pipeline diameter, transportation medium, service temperature, welding requirements, and the design standard specified by the project. If you're unsure which grade is suitable, sharing your technical specification or project requirements allows us to recommend the most appropriate material.

    Yes. Plates can be cut to customer-specified dimensions before shipment. Additional services such as beveling, drilling, shot blasting, surface preservation, and CNC flame cutting are also available, helping reduce fabrication time after delivery.

   Yes. Pipeline steel plates can be supplied with third-party inspection upon request. Inspection agencies such as SGS, BV, TUV, Lloyd's Register, or other customer-designated organizations can witness production, verify dimensions, review mechanical properties, and issue inspection reports before shipment.
