There are four main colors of PPR pipes on the market: white, gray, green, and curry color, mainly because of the different masterbatches added, it is recommended to buy white PPR pipes, which is to avoid the use of recycled materials by manufacturers to produce PPR water pipes, and to cover up the defects caused by impurity of raw materials by adding color masterbatches.

Good soft PPR pipe, the pipe fittings are not easy to be deformed by extrusion, even if deformed, they will not break, and greatly reduce the amount of joints used, which can resist the erosion of chemical elements in water, and the smooth inner surface can avoid the formation of scale. The water pressure of the pipe fittings at room temperature is 45 kg/cm², the temperature of the pipe is not deformed at 112 degrees Celsius, and the PPR pipe has a long life, the pipe fittings have strong anti-aging, and the normal function mission reaches more than 50 years, the flexibility of the pipe fittings makes the construction very fast, and easy to connect (connected with a hot melt machine socket), safe and reliable, due to the simple construction, there is no contradiction and influence between the pipe and other projects, shorten the construction period, and the construction cost is 60% less than the copper pipe, which has superior economy.

PPR The main component of the pipe is propylene, which is mainly used as a household water supply system, and the diameter of the PE pipe is much larger than that of the PPR pipe, the main chemical molecular component is polyethylene, PE is the main pipeline water supply, Under normal circumstances, PPR pipes and PE pipes cannot be hot-melt connected, and the internal teeth should be directly connected with the external teeth, and the wall thickness is inconsistent, and the welding strength of the two materials cannot meet the requirements.

After PE is introduced into the room, it is connected with PPR pipes, the small pipe diameter is converted by metal, the large pipe diameter is converted by flange, the cast iron pipe and the steel pipe are flanged converted outdoors, the flange masonry is easy to overhaul and replace with soft connection, the correct connection method is to connect with flanges, and the small diameter pipes can also be connected with tooth fittings, so as to effectively ensure the connection strength and ensure the quality of the project.
