Sewage pipes sewer pipes lined steel roller Features:? 1. It has excellent physical performance? 2. It has excellent corrosion resistance? 3. Health non-toxic, non-fouling, non-breeding microorganisms, fluid quality assurance? 4. Chemical resistant, corrosion-resistant soil and marine life, resistance to cathodic stripping widely used in petroleum, chemical, chemical, chlor-alkali, dyes, pesticides, pharmaceuticals, environmental protection, metallurgy, electric power and other sectors of the media transport and environmental treatment systems, drinking water projects and to drainage works. Sewer pipes lined steel roll steel roller track main features: 1, the use of advanced rotary melt new technology internationally, with a large rotary presses once pattern forming domestic initiative 2, seamless, impact.? anti-static, non-toxic, medium temperature -15 ° C -. + 90 ° C resistant to positive and negative pressure, and a molding, etc. 3, spot welding metal mesh strengthened so (PTFE) materials and metal mesh intertwined. melt as a whole, firmly polymerization cooled on the inner surface of the device, and the overall strength of the steel, and will not delaminate, long-term use under negative pressure. 4, the performance ability of various concentrations of acid, alkali, salt and some corrosive organic solvents, can replace stainless steel, titanium, ceramics, rubber and other similar products, the price is relatively cheap, easy to shape, can be widely used in large and complex equipment Lined shaped device. 5, PTFE products can be made use of secondary repair. Corrosion resistance similar to PP. Sewers heat rotomolding (PTFE) pipes and fittings is the use of 20 # seamless steel pipe inner surface after rust treatment. All with the overall steel shell lined with plastic overall rotational molding. No plastic weld completely overcome some plastic. Disadvantages: poor welding properties (such as PP, etc.) to make products more reliable and durable. Can withstand high temperature, high pressure, to eliminate the phenomenon of thermal expansion and contraction coefficient Plastic Peng Zhang produced inconsistent. Is the acid pipeline corrosion chemical companies, power companies of the water, in addition to the salt water, sewage treatment, de-sulfur corrosion engineering choice wear-resistant pipe. Be my defense Corroded upgrade products. is no splash stream to provide a reliable guarantee delivery specifications and availability in a DN25 3500mm. Any special parts and non-standard parts can be customized according to FIG.
