General colors: black, gray, blue, red, white, green; Coating thickness: PE(modified polyethylene) coating thickness of 400um - 1000um, EP(epoxy resin) coating thickness of 100um-400um; Coating method: PE(polyethylene) for hot dip EP, (epoxy resin) for internal and external spraying; Product specifications: DN15 -- DN1660; Ambient temperature: -30℃ to 120℃; Connection mode: screw buckle (DN15-DN100), groove (DN65-DN400), flange (applicable to any caliber), welding type, bimetal connection, socket, pipe joint, sealed connection, etc.1. Various forms of circulating water system (civil circulating water, industrial circulating water), excellent performance, anti-corrosion life up to 50 years. 2. Fire water supply system. 3. Water supply and drainage of each building (especially for cold and hot water systems of guesthouses, hotels and high-end residential areas). 4. All kinds of chemical fluid transport (acid, alkali, salt corrosion). 5. Buried pipe and crossing pipe of wire and cable. 6. Ventilation pipes, supply pipes and drainage pipes of mines and mines1. Adapt to buried and humid environment, and can withstand high temperature and very low temperature. 2. Strong anti-interference ability. If coated plastic steel tube is used as cable sleeve, it can effectively shield external signal interference. 3. Good pressure strength, maximum pressure up to 6Mpa. 4. Good insulation performance, as a wire protection tube will never happen leakage phenomenon. 5. No burr, smooth pipe wall, suitable for the construction of wire or cablePowder coated plastic steel tube, Is the use of PE(modified polyethylene) hot-dip plastic or EP(epoxy resin) for internal and external coating products, with excellent corrosion resistance. At the same time, the coating itself also has good electrical insulation and will not produce electrical erosion. Low water absorption, high mechanical strength, small friction coefficient, can achieve the purpose of long-term use. It can also effectively prevent the destruction of plant roots and soil environmental stress. Convenient connection and easy maintenance.
