Lined steel pipe manufacturers

After the product structure to determine what technology of production is a vital economic activity, it is directly related to the cost of production and production efficiency, while in turn the structure of the product design, choice of materials presented on process Claim. Lined steel reinforcement embedded within a unique complex mechanical drawing process, through the metal tube necking oppression inner plastic tube, two materials cause permanent reasonable interference, coupled with the inner surface of the pipe inner ribs unique tread design Embed effect on the plastic surface of the tube, as well as physical and chemical modification of composite plastic pipe before such reinforcement embedded within the plastic-lined steel pipe with a non-hierarchical, indented tube, long-term use is guaranteed technical characteristics. And won the national utility model patents in 2001. This unique process to produce high efficiency, process control easy, high quality composite. Galvanized coating inside water outside epoxy composite pipe galvanized pipe wall using a modified epoxy resin powder or water supply of food-grade polyethylene powder coated composite pipe water supply. Inside wall coating with excellent overall performance, with strong corrosion resistance and excellent chemical stability, it can transport fluid medium of -30 ℃ ~ 90 ℃. After testing with the drinking water distribution equipment and protective materials, safety evaluation criteria of. The inner wall of the coating adhesion, excellent impact resistance and strong anti-cathode peeling. Since the pipe wall surface is smooth coating to prevent microbial growth and scale, while conveying the fluid resistance, increase traffic, saving energy. Water inside the outer plastic composite pipe galvanized applies to drinking water supply pipes, pipe connections, using groove fittings, malleable iron pipe thread fittings and flanges. Can withstand the pressure of 25Kg or less.
