Shanghai Metal Corporation is a leading PPR Pipe manufacturer and supplier.
PPR is the acronym for Polypropylene-Random. Commonly known as three-type polypropylene. PPR pipe is the replacement product of UPVC water supply pipe, aluminum-plastic pipe, PE pipe, PE-X pipe and PE-RT pipe. Because it uses random copolymerization technology, the strength and high temperature resistance of polypropylene are well guaranteed, thus becoming the main force of water pipe materials.
If you want to know more about our PPR Pipe or get price please feel free to contact us, we will reply you within 24 hours.
1. Non-toxic and hygienic
PP-R's raw material molecules are only carbon and hydrogen elements, and there are no harmful and toxic elements. It is hygienic and reliable. It is not only used for hot and cold water pipes, but also for pure drinking water systems.
2. Insulation and energy saving
PP-R pipe thermal conductivity is 0.21w/mk, which is only 1/200 of steel pipe.
3. Better heat resistance
PP-R tube has a Vicat softening point of 131.5°C. The maximum working temperature can reach 95 ℃, which can meet the requirements of the hot water system in the building water supply and drainage specifications.
A. The cold and hot water system in the building, including the central heating system.
B. The heating system in the building, including floor, siding heating and radiant heating system.
C. Direct drinking water supply system.
D. Central air-conditioning supply and return water system.
E. Agriculture, garden irrigation system.
F. Rainwater pipe network.
Cutting: Cut the pipe, and use a pipe cutter to cut it vertically. If there is no pipe cutter, use other tools to cut the pipe. After cutting, the cutting head should be cleaned.
Heating: When the fusion splicer is heated to the working indicator green light, the pipes and fittings are simultaneously pushed into the melter and heated to 5-7 seconds.
Connection: The heated pipe and fittings are pushed vertically and maintained for more than 10-12 seconds. Do not push too hard when pushing to prevent the pipe head from bending.
Pressure test: In order to ensure the quality of the welding, the pressure test shall be conducted after 24 hours of pipeline connection.
Acceptance: Before the pipeline project is completed and delivered for using, it must be pressure tested for acceptance before it can be sealed for use.
Insulation: Insulation and sun protection measures should be taken when laying outdoors or exposed to freezing indoors.
Packing of PPR Pipe:
Precautions during hot melt:
1. Before heat welding, make sure the pipe and pipe fittings are clean.
2. Pipes and fittings are pushed into the welder mold with both hands.
3. When the pipe and pipe fittings are overheated, the pipe will be deformed in the pipe fittings, and water leakage may occur.
