Shandong Plastic Co., Ltd. is a modern new enterprise integrating scientific research, development, production, and sales of PE pipes and PE water supply pipes. The products are reasonable in price, complete in specifications, and can be customized according to customer requirements.
Which PE pipe is better? The products produced by our company have the following advantages: reliable connection: the electric heating between the polyethylene pipe system is melted, and the strength of the connection joint is higher than the strength of the pipe body; it has good low temperature and impact resistance: low polyethylene low temperature brittle temperature can Used in the temperature range of -60-60 ° C. Because in the winter construction materials, the impact resistance is good, and there will be no tube brittleness; it has good stress crack resistance: high density polyethylene has lower notch sensitivity, high shear strength and excellent scratch resistance, The resistance to environmental stress cracking is also very outstanding; it has good chemical resistance: high-density polyethylene pipes can withstand the corrosion of chemical media, chemicals, all kinds of substances in the soil will not cause any degradation of the pipeline; aging resistance, service life Length: The carbon black polyethylene pipe with 2-2.5 is evenly distributed, can be stored in the open air or used for 50 years, and will not be damaged by ultraviolet radiation. It has good abrasion resistance, flexibility and easier bending.
The connection methods of PE water supply pipes are mainly as follows: 1. Hot-melt connection is to use special heating tools to heat the polyethylene pipe or pipe to be connected under pressure, make it melt, remove the heating tool, and apply pressure. Connect the two molten faces together and hold for a while under steady pressure until the joint cools. Hot-melt connection includes hot-melt butt connection, hot-melt socket connection, and hot-melt saddle-type connection; 2. Electric-weld connection is to use a special electric-welded pipe with a built-in resistance wire in close contact with the PE pipe or pipe connection. The PE pipe heats the connection part through the embedded resistance wire, making it melt and join together until the joint is cooled. Electrofusion connection can be used to connect with different types of polyethylene pipes or socket fittings with different melt flow rates. Electrofusion connection is divided into fused socket connection and fused saddle connection. 3. Socket-type flexible connection is a type developed based on the socket-type flexible connection principle of cast iron pipe and polyvinyl chloride pipe (PVC-U). New connection method, one end of the pipe is welded with a reinforced polyethylene socket. The socket-type flexible connection is to insert one end of the polyethylene pipe directly into the special socket of the pipe or pipe fitting, and then use the locking ring in the socket to squeeze the anti-pulling and rubber seals to seal and achieve the purpose of connecting the pipe and the fitting; 4. The flange connection is mainly composed of polyethylene flange connector, steel or aluminum back-pressure looper flange, steel or aluminum flange piece, gasket or seal ring, bolt, nut, etc. The flange connection is to achieve the connection purpose by tightening the bolts and nuts to make the flange connection piece and the flange piece tightly contact. 5. Steel-plastic transition joint connection is to connect polyethylene pipes and metal pipes by cold-pressed or other prefabricated steel-plastic transition joints. Steel-plastic transition joints have pull-resistant locking rings and seals, which usually require good sealing performance, pull-resistant and pressure-resistant performance to be greater than polyethylene pipes in the system.
