Plastic pipe preheating temperature control

Plastic composite pipe, is a steel matrix, by spray, roller, dip, suction process in steel (bottom tube) welding the inner surface of the coating layer of plastic or plastic composite pipe welded inside and outside surfaces of the plastic coating.

Preheat plastic pipe coating stage, preheat temperature control at 150 , after half an hour you can paint processing. Painting can be used when spraying or dip, high-voltage electrostatic spray painting is by way of the epoxy powder coated steel surface, dip is directly immersed in the well pipe, filling epoxy powder. 
Plastic pipe having excellent corrosion resistance and a relatively small frictional resistance. Epoxy coated steel pipes for conveying water supply and drainage, water, warm water, oil, gas and other media, PVC plastic pipe for conveying drainage, water, oil, gas and other media. Plastic pipe is the use of PE (polyethylene modified) or hot dip EP (epoxy) coated inside and outside of the product, has excellent corrosion resistance. Meanwhile coating itself also has good electrical insulation, does not produce galvanic corrosion. Low water absorption, high mechanical strength, low coefficient of friction, can achieve the purpose of long-term use. Can effectively prevent the destruction of plant roots and soil environmental stresses. Connection convenient, easy maintenance.
Hot dip steel can be called hot dip coated steel, the different nature of it and electrostatic spraying, the polymer coating is corrosion by high-pressure electrostatic plastic powder coated steel surface sprinkled in, and dip is put directly into the pipe Plastic wells polymer powder, processing the same purpose of these two are so welded at high temperature plastic powder in the surface of the pipe to form a composite tubular body. Diameter steel pipe is guaranteed due to the existing ordinary ordinary galvanized steel lined with plastic, so its actual diameter composite pipe significantly less than the specified diameter, coupled with its joints to achieve corrosion requirements, the actual path lined after its less than the specified diameter of 1/3. Lined steel reinforcement embedded within the outer layer of galvanized steel is specially processed, so its actual diameter composite pipe is fully consistent with the provisions of diameter, and pipe joints no path loss. 
Inner pollution prevention measures to improve: the use of ordinary steel pipe fittings to connect the traditional way, will cause secondary pollution of water after fitting threaded outer rust. Steel bars embedded in the plastic-lined using quick connect fittings, interior fittings in his possession were all lined handle, when connected to the pipe, the pipe system is not any metal material portion of the fluid in contact with the transmissionPsychology Articles, it is possible to effectively prevent the water quality secondary pollution.
