Coal mine pe pipe (pe mine tube) high density polyethylene (HDPE) is non-toxic, tasteless, odorless white particles, the melting point of about 130 ℃, the relative density of 0.941 ~ 0.960. It has good heat resistance and cold resistance, chemical stability, but also has high rigidity and toughness, good mechanical strength. Dielectric properties, resistance to environmental stress cracking resistance is also good. Coal mine pe pipe (pe mine tube) connection: Plastic connection: to use flange, threaded threaded connections and other methods. Electric welding: the use of special electric hot-melt welder will be straight with straight, straight pipe and pipe fittings connected. Generally used for the following pipe 160mm. Butt connection: Special butt welding pipe connected, generally used for more than 160mm pipe. To facilitate construction and ensure the construction quality, but also to prepare the appropriate tools. Such as: a rotary cutter cutting pipe; rotating scraper - scrape the tube surface oxide; climbing wall scraper - scrape the surface of the skin of large-diameter pipe; breathe Tools - achieve expire site operation. Coal mine pe pipe (pe mine tube) application areas: HDPE pipes are mainly used: municipal water systems engineering, building indoor water supply systems, water supply systems and outdoor buried residential area, the plant underground water supply systems, the old pipe repair , industrial water treatment projects in the pipeline system, garden, irrigation and other areas with water pipes. But it notes that HDPE pipe can not be used for hot water pipes. HDPE (high density Polyethylene) pipe currently supplies municipal pipe market in China, is steadily developing plastic pipe, PE pipes, PP-R pipe, UPVC pipes have a place where the strong momentum of development of the most remarkable PE pipe. Extensive field use PE pipe. Water and gas pipes which are the two largest application market.
