PPR Pipe Simple And Very Practical
PPR Pipe: As a new type of pipe material, PPR pipe has a unique advantage, it can be used as a cold tube, can also be used as hot water pipe, because of its non-toxic, light, pressure, corrosion resistance, A promotional material. Also applies to hot water pipes, and even pure drinking water pipes. PPR pipe interface using hot melt technology, the pipe completely integrated together, so once the installation of compression test through, and PPR Pipe will not scale
PP-R pipe fittings, the use of high-quality raw materials from injection molding, the performance of the products meet or exceed the national standard GB / T18742 the required indicators. Also has the following unique design and process advantages:
The use of large curvature of the bend design, can effectively reduce the formation of water hammer, to prevent the phenomenon of Zhenzhen occurred.
45 degree chamfer design, making welding easier.
PP-R is a random copolymer of polypropylene, that is, we call the type Ⅲ polypropylene. It is obtained by random copolymerization of propylene monomer and a small amount of ethylene monomer under heating, pressurization and catalyst. The ethylene monomer is randomly distributed to the long chain of propylene, wherein the vinyl monomer is generally controlled between 3-5%. Ethylene content and the polymerization of ethylene and propylene determines the characteristics of its cold brittleness. In the case of low temperature, especially in the winter construction process, the pipe at low temperature flexibility has been reduced, rigidity increased, the performance of brittle. In the external impact or excessive accident load, the possibility of pipe cracking and other cases. To the construction of inconvenience. For which the relevant national norms have made clear requirements for this issue. In the winter construction, should pay attention to the construction of water supply polypropylene (PP-R) pipeline low temperature brittle characteristics, and develop the corresponding construction program. GB / T50349-2005 this has a detailed requirement.
This method of judgment is wrong, can crack the PPR Pipe, which is a good mistake to determine the PPR errors, which does not test the PPR is good or bad, because the PP-R material itself with the performance of the ambient temperature The degree of change. In the case of low temperatures, especially in the winter pipe at low temperatures, flexibility is reduced, rigidity increased, the performance of brittle. In the external impact or excessive accident load, the possible fracture of the pipe and so on. To the construction of inconvenience. For which the relevant national norms have made clear requirements for this issue. In the winter construction, should pay attention to building water supply polypropylene
Most of the decoration or renovation of the owners for the home improvement when used PP-R (random copolymer polypropylene) water pipe can be described as ignorant, or hearsay that a lot of incorrect identification of good or bad methods, such as the current more popular one Kind of argument - "with the hammer to smash, hit the crack is not good, smashing is poor quality," this method is indeed very simple and practical on the surface, but the thin analysis is actually a misleading.
PPR water pipe consumers in the decoration is the preferred PPR Pipe ten brands of water pipes, all-round pipe is one of the top ten brands of PPR Pipe, and all the use of high-quality ppr raw materials in the market has made wide acclaim, is the current PPR Pipe Agents of the best choice, today all-around pipe to give you about the installation of all-round tube hot melt:
First of all, according to the size of the diameter of the use of different touch head, installed in the heating plate; and then plug in, open the switch
Second, set the required temperature, the indicator light from red to yellow when the temperature reaches the set temperature;
Finally, the first ppr pipe into the touch head, insert nearly half of the depth, the pipe into the touch head, to be reached at the same time to achieve the same depth and even when the overflow material, the pipe and pipe fused together in 3 seconds on the straight, Can not rotate, and then stabilize, to be cooled after the release, welding completed.
