Seamless Steel Rubber Lined Pipe DN25-DN1200 Corrosion Resistant Industrial

Product Description:

The Seamless Steel Rubber Lined Pipe is a high-integrity industrial pipeline engineered specifically for oil, gas, and sewage transport applications where leak-proof performance and corrosion resistance are critical. Manufactured using American Standard seamless steel pipe technology, the outer shell provides superior structural uniformity without weld seams that could become potential failure points under high-pressure fluid conveyance conditions. The premium multi-material rubber lining delivers exceptional resistance to hydrocarbons, hydrogen sulfide, sewage effluents, and chemical contaminants commonly encountered in oilfield and municipal wastewater systems.

The seamless steel construction eliminates the longitudinal weld seam inherent in welded pipes, providing consistent wall thickness and uniform mechanical properties throughout the entire pipe length. This is particularly important for high-pressure oil and gas transport where weld seam stress concentration can lead to premature failure. Combined with natural rubber, neoprene, EPDM, or nitrile lining materials, the pipe offers tailored chemical resistance for specific fluid compositions while the rubber layer provides additional sealing integrity at flange connections.

Available in DN25 to DN2000 diameters with standard ANSI/DIN/JIS flanged connections, this seamless steel rubber lined pipe integrates seamlessly into existing oilfield gathering systems, gas transmission networks, and sewage treatment plant piping. Liwei provides full OEM and ODM customization including specialized rubber compounds for sour service (H2S resistant), custom lengths, and non-standard flange drilling patterns.

Applications:

This seamless steel rubber lined pipe is purpose-built for oilfield gathering and injection systems, natural gas transmission laterals, and municipal sewage transport where seamless pipe integrity and corrosion resistance are mandatory requirements. The absence of weld seams eliminates the most common initiation point for stress corrosion cracking in sour service environments, while the rubber lining provides a robust chemical barrier against internal corrosion from produced water, hydrogen sulfide, and carbon dioxide.

In sewage and industrial wastewater applications, the seamless construction combined with chemical-resistant rubber lining prevents leakage of hazardous effluents into surrounding soil and groundwater, ensuring environmental compliance. Liwei manufactures all seamless steel rubber lined pipes under strict quality control with ISO 9001, TUV, WRAS, CO, MTC, PL, and IV certifications. Each product undergoes hydrostatic pressure testing and lining integrity inspection before shipment with a one-year warranty.
