PPR pipe is officially known as the random copolymerized polypropylene pipe, is currently Jiezhuang works by a water supply pipe.
The hot melt technology of PPR pipe interface, between the pipe completely fused together, so once the installation of pressure test, will never Water Leakage, high reliability. But this is not to say that PPR pipe is not defective hose,high temperature resistance, pressure resistance is little worse, long-term working temperature should not exceed 70 ℃; each segment length is limited, and must not be bent construction, if the pipeline laying long distance or the corner, in the construction will be used a lot of joint; pipe cheap but accessories relatively high prices. From theperformance of speaking, PPR is the higher price of pipe, so become the first choice for home improvement materialswater reform.
The market sales of PPR pipe mainly has two kind of colors, white and grey, why there is this difference, the dealer's answer is the raw material of PPR particles caused by different.
In general, water and electricity transformation, the original water can replace, Jiezhuang companies and businessesto install the PPR tube with hot water pipe in the proposed fitting, even the cold water flowing through the place withhot water pipe. They say is due to the technical parameters of the hot water pipe is higher than that of the cold water pipe, and the price difference, so the water transformation with the hot water pipe. Another is the fact that even if youwant to market is also very difficult to buy buy cold water, because cold water pipe supply only tooling market, notsupply Jiezhuang market.
Diameter PPR pipe diameter can be from 16mm to 160mm, Jia Zhuang, mainly use the 20mm, 25mm two(respectively, commonly known as 4 in, 6 in, 4 of which work) to more.
pipe with plastic pipe features of light weight, corrosion resistance, no scale formation, long service life, but alsohas the following main features:
1, non-toxic, health. Raw material molecular PP-R only carbon, hydrogen, no toxic harmful elements exist, health can be *, not only for the cold and hot water pipes, but also can be used for pure drinking water system.
2, energy-saving insulation. Thermal conductivity of tube is 0.21w/mk PP-R, only for the steel 1/200.
3, good heat resistance. PP-R VEKA softening point 131.5 ℃. The maximum operating temperature up to 95 ℃, canmeet the building to use the hot water system, drainage standard.
4, long service life. PP-R tube in the working temperature is 70 ℃, working pressure (P.N) under 1.OMPa conditions,the service life of up to 50 years; room temperature (20 ℃) with a life span of 100 years.
5, convenient installation, reliable connection. PP-R has good welding performance, pipe, pipe heating and welding connection, convenient installation, the joint can be *, the joint strength is greater than the strength of the pipe itself.
6, the material Recyclable utilization. PP-R scrap through cleaning, crushing recycling in pipes, pipe fittings. No more than 10% of the total amount of recycled material, does not affect the quality of the products.
