Home building materials PPR pipe network elements
PPR pipe officially called random copolymer polypropylene pipe, water pipe is home improvement projects.
PPR pipe interface using a hot melt technology, fully integrated in the tube, such a pressure test, once installed, never lose very reliable. However, this does not mean that the PPR pipeline pipe damage, a little 'high temperature resistance, pressure resistance, long running temperature not exceeding 70 DEG C, the length of each segment is limited, can not bend the construction, if the distance or angle necessary intake pipe, the pipe joint construction of the use of a large number of cheap, but the price relatively high part. The overall performance of the PPR tube is expensive, and it has become the favorite pipeline to improve the decoration material.
PPR pipe market there are three kinds of colors, white, green and gray, PPR and filler particles of raw materials are different between the results, why the dealer's answer. PPR tubes are green and white with the highest quality materials, gray, a little 'more than the time difference material.
Water in general, the reform will replace the existing pipeline, all pipes in the house with hot water and the proposed construction of the installation of PPR pipe, even in cold water, hot water pipes. They said that cold water pipes, hot water pipe stems, water pipes with water-saving transformation, technical parameters and price differences. Another fact is that if you want to buy cold water pipe market is also difficult to buy, because you are a single cold water market, rather than providing home improvement market.
Diameter PPR pipe diameter of 16 mm to 160 mm home improvement is mainly used for the 20 mm to 25 mm (commonly known as the six is responsible for) for further use, they are responsible for the four people in charge of the use of home improvement ().
In the first place, what is the PP-R tube?
PP-R pipe 3 is also known as polypropylene pipe, polypropylene random copolymer, through the catheter extrusion, injection molding parts. In Europe in twentieth Century, from the beginning of 90 years, the development and application of new plastic pipe products. PP-R is the use of the polymerization process in the late 80s of the late 20th century in the gas phase, making up about 5% of the total PE of the random molecular chain of polypropylene (random copolymer), a new generation of piping materials. Good impact resistance and long-term creep resistance.
PP-R, is there any connection with PP-C?
Some time ago, the local market, with PP-C, PP-R pipe and pipe fitting methods are consistent. Many people do not know, PP-R, PP-C, created a lot of misunderstanding and confusion. International standards for polypropylene, hot water and cold water pipeline stars PP-H, PP-B, PP-R, PP-C. In fact, the pipe market PP-C PP-B pipe, piping material of polypropylene resin block copolymer. PP-B pipe is hot and cold water pipes, the price is relatively cheap, heat resistance, pressure resistance, the difference between PP-R. For example, in the use of second conditions, the design pressure of 0.6MPadn25mm pipe, PP-R pipe thickness of 3.5 mm, 5.1 mm PP-B (PP-C); the design pressure is 0.8MPadn25mm PP- may use "the thickness of 4.2, PP-B (PP-C) from the thickness, because the required thickness is too thick and the size of the market structure is PP-R PP-C pipeline the same, using much less, must not be confused with the use of PP-R pipe, can under certain conditions, can not use the alternative design temperature of polypropylene PP-R pipe pipe C shown in Figure 2 to 70 DEG C water condition.
What are the characteristics of the PP-R tube?
In addition to the general plastic, light weight, did not form a scale, long live corrosion resistance and other properties, but also has the following main features: non-toxic, sanitary fittings, PP-R pipe. PP-R molecules only hydrogen carbon material, there is no harmful toxic elements exist, the health can not be used pipe can also be used for hot and cold water clean drinking water system.
2, heat preservation and energy saving. PP-R tube thermal conductivity 0.21w/mk, only for steel pipe 1/200.
Third, better heat resistance. VEKA PP-R softening point. Maximum operating temperature up to 95 DEG C under hot water system to meet the requirements of building codes.
4, long service life. Working temperature PP-R pipe 70 DEG C, working pressure (PN) 1.OMPa conditions, life of up to more than 50 years; up to 100 years, at room temperature (20 degrees C).
5 installation, easy connection can *. PP-R has a good welding performance and the furniture mix melting joint can be connected conveniently by virtue of the pipe connection part.
6 recyclable materials. PP-R pipe production washing, crushing and recycling waste. The total amount of recycled material does not exceed 10%, without affecting the quality of the product.
What is the main purpose of the PP-R tube?
1, cold and hot water systems, including central heating system;
2, heating systems in buildings, including floors, walls and floor radiant heating systems;
3, pure drinking water supply system;
4, the central air-conditioning system (medium);
5, the transfer or release of chemicals in the industrial pipeline system real estate agent.
