PPR pipe called three polypropylene tube, through the use of random copolymer polypropylene extruded into pipes, injection molded into the tube. Europe in the early 1990s the development and application of new plastic pipe products. PP-R is the late 1980s, using a gas phase copolymerization process so that about 5% PE in the molecular chain of PP random evenly polymerization (random copolymer) and a new generation of pipe materials. High strength, impact resistance and has good long-term creep performance. Life of up to 50 years, the market does not have any kind of cheaper materials can replace it. PPR pipe is used in most home improvement projects a water supply pipeline. PPR pipe interface with hot-melt technology, between the tubes completely fused together, so once installed pressure test through, never again leaks, high reliability. This is not to say that the water is not defective PPR pipes, heat resistance, pressure resistance somewhat less, long-term working temperature should not exceed 70 ℃; each finite length, and can not bend construction, long distance or if the pipeline around the corner and more, in the construction necessary to use a large number of joint; pipe fittings cheap but the price is relatively high. From the overall performance is concerned, PPR pipe is the high cost of the pipe, so the material of choice for home improvement plumbing transformation.
In the water reform in general, will replace the existing pipes, hot water pipes when all selected home improvement companies and businesses in the proposed installation of PPR pipe fitting, even if the cold water flowing through places with hot water pipes. PPR pipe diameters from 16mm to 160mm, home improvement is mainly used in 20mm, 25mm two kinds of (respectively known as 4 charge, charge 6), which used some more 4 charge. PP-R pipe in addition to general plastic tube with a light weight, corrosion-resistant, non-scaling, long life and other characteristics, but also has the following main features: non-toxic and health. PP-R materials molecule only carbon and hydrogen elements, no harmful toxic elements are present, hygiene can be *, not only for the hot and cold water pipes, can be used to clean drinking water systems. Energy-saving insulation. PP-R pipe thermal conductivity of 0.21w / mk, only steel pipe 1/200. Good heat resistance. Vicat softening point of PP-R pipe 131.5 ℃. The maximum operating temperature of up to 95 ℃, to meet building water specification requirements of hot water system. long lasting. PP-R pipe in working temperature 70 ℃, working pressure (PN) 1.OMPa conditions, the service life of up to 50 years; at room temperature (20 ℃) life of up to 100 years. Recyclable materials. PP-R waste through clean, after crushing recycling in pipe, tube production. Regrind amount does not exceed 10% of the total, does not affect product quality.
PPR PP-
1. polymerized from a monomer molecule from macromolecules called homopolymer (Homonolymer), composed of two or more than two kinds of molecules called monomers polymerized macromolecular copolymer (Copolymer);
2.PP-H is the polymerization of propylene Propylene monomer molecule made of a homopolymer;
3.PP-B and PP-R is polymerized from propylene monomer and ethylene monomer Ethene Propylene copolymer formed by (Poly Propylene Copolymer, i.e. PP-C) wherein:
1) The use of advanced technology gas copolymer, PE in the molecular chain of PP random, the polymerization uniformly, this material commonly known as PP-R (polypropylene random copolymer);
2) the use of PP and PE block copolymer, this material commonly known as PP-B (polypropylene block copolymer) .
What is PPR pipe? PPR pipe: As a new water pipe material, PPR tube has unique advantages, it can be used as cooling pipes, hot water pipes can also be used, because of its non-toxic, light, pressure, corrosion resistance, is becoming An extended material. Also applies to hot water pipes, and even clean drinking water pipeline. PPR pipe interface with hot-melt technology, between the tubes completely fused together, so once installed pressure tested, not like the presence of aluminum pipe as a long time aging water leakage, but not scaling PPR pipe.
