LINE PIPE
Founded in 2013, Yantai Xinbaoshang Materials Technology Co., Ltd.
China's leading line pipe manufacturer and supplier
Pipeline pipes are steel pipe products specifically designed and manufactured for the safe and efficient transportation of various fluid media. They form the core component of transmission networks for petroleum, natural gas, water, and other industrial fluids. Their production adheres to international standards such as API and ASTM, employing processes like seamless rolling or high-frequency resistance welding (ERW) to ensure the pipe body's reliability under high-pressure, corrosive, and variable load conditions. Pipeline pipes effectively resist internal pressure, external impacts, and geological stresses, ensuring safe long-distance transportation. Products can be selected from different grades of carbon steel, alloy steel, or stainless steel based on the corrosiveness, temperature, and pressure rating of the conveyed medium. Special treatments such as internal coatings, external anti-corrosion layers, and insulation layers can be applied to withstand extreme environments and extend service life. Due to their critical transport performance and enduring durability, pipeline pipes are widely used in major engineering projects including onshore and subsea oil and gas pipelines, urban water supply and drainage systems, chemical medium transportation, and strategic energy reserves.
As a leading manufacturer and supplier of line pipe products in China, our products cover most application scenarios in terms of size and standards. Our products strictly comply with international standards such as API and ASTM. If you have any other requirements for product specifications, please feel free to contact us for customization.
