PPR Pipe Cap/Pipe Fittings
Green PPR pipe called three polypropylene tube, through the use of a random copolymer polypropylene extruded into tubing, injection molded into the tube. Europe in the early 1990s to develop the application of new plastic pipe products. PPR is the late 1980s, the use of gas-phase copolymerization process makes about 5% PE in the molecular chain of PP random evenly polymerization (random copolymer) and a new generation of pipe materials. It has good impact resistance and long-term creep properties.
***Features of Green PPR Pipe Fittings
Green PPR pipe fittings in addition to general plastic tube with a light weight , corrosion , scaling , long life and other characteristics, but also has the following main features:
1 , non-toxic , health . PPR raw molecules only carbon and hydrogen elements , no harmful toxic elements are present , reliable health, not only for the hot and cold water pipes , but also for pure drinking water systems .
2 , thermal insulation . PPR pipe thermal conductivity 0.21w/mk, steel is only 1/200.
3, preferably heat resistance. Vicat softening point PPR pipe 131.5 ℃. The maximum operating temperature of up to 95 ℃, water supply and drainage construction to meet the requirements of the specification using hot water system .
4 , long life . PPR pipe operating temperature 70 ℃, working pressure (PN) 1.OMPa conditions , the service life up to 50 years ; room temperature (20 ℃) life of up to 100 years.
5, easy to install , reliable connection . PPR has good weldability, pipes, fittings can be melt and fused connection , easy to install , reliable joints connecting parts is greater than the strength of the strength of the pipe itself .
6 , the material is recyclable . PPR waste cleaned , crushed and recycled in pipe, tube production . Recycled material
The amount does not exceed 10% of the total , does not affect product quality.
***Use of Green PPR Pipe Fittings
1, building hot and cold water systems, including central heating systems;
2, the building heating system, including flooring, siding and radiant heating systems;
3, can be directly purified drinking water supply systems;
4, Central (centralized) air-conditioning systems;
5, transfer or discharge of chemical mediators such as industrial piping systems.
***PPR Pipe Connection Method
1.A view of the die is complete
2.The die is fixed by screws stresses hotplate
3.Reinforcement die with a hex wrench
4.Cutter the PPR pipes, and remain flat fracture.The pipes and fittings vertically into heat welding head
5.After sufficient heating, pipes and fittings pulled out quickly inserted vertically and remain for some time in normal weld joints should have a uniform weld ring.
