The common PPR household pipes in the market have many colors, such as green, white, gray, and even blue, yellow, orange, etc. The main reason for the emergence of such a variety of colors is that different colors of "color master" are added in production. What is the "color master"? What is color master? The raw materials of color masterbatch mainly include: carrier, colorant and additives. Carrier is an important component of color master batch. Its main function is to carry colorants and disperse them into plastics that need to change color. Colorants are the key components in color masterbatch, which make color masterbatch present different colors; The content of additives is small, generally to help the colorant disperse or obtain some special properties, such as oxidation resistance, light stability, etc. Color masterbatch is generally divided into general color masterbatch and special color masterbatch. Their difference lies in the choice of carrier

PPR pipes and supporting pipe fittings from the same brand manufacturers should be used as much as possible in the domestic water pipe installation project. The reasons are as follows: PPR pipes and pipe fittings from different brands with more perfect connections are different in terms of product quality, performance, melting point and other aspects due to the use of different raw materials. The combination of pipes and fittings from different manufacturers may directly affect the combination quality of pipes and fittings. Different melting points and welding conditions will make it more difficult to control the quality of welding. Using products of the same brand series will make the pipeline connection more perfect. No size error The size of pipes and fittings produced by the same manufacturer has been repeatedly tested by the manufacturer, so there is almost no error between pipes and fittings. Because different brands are produced by different manufacturers, even if they are of the same specification, there will be errors, which will lead to

Can PPR household pipes and PPR accessories of different brands be mixed? What do we think about this problem? We believe that PPR pipes and fittings of different brands can be mixed in theory, but we do not recommend this. Why can it be mixed in theory? This is because the main raw material for manufacturing PPR water pipes is random copolymerized polypropylene. If you do not weld PPR water pipes with water pipes of other materials (such as PE pipes and PB pipes), they can be fused together in theory. Raw materials for PPR household pipe production can be divided into premix and self batching. The proportion of each group of premix is fixed, while the proportion of each group of self batching is controlled by the manufacturer. Then, why don't we suggest mixing PPR pipes of different brands? It is mainly based on the following two points:

Compared with traditional copper pipes, stainless steel pipes, plastic clad metal pipes and other pipes, PPR household pipes have the advantages of non-toxic health, heat preservation and energy saving, good heat resistance, and long service life. But at the same time, PPR pipe also has its special characteristics - low temperature brittleness. How to extend the life of PPR pipe more effectively while enjoying its health and environmental protection advantages? Note 1: Pay attention to protection during handling and construction. Compared with metal pipes, PPR pipes are characterized by low hardness and poor rigidity. Therefore, special protection shall be provided during handling and construction to avoid damage to pipe fittings and pipes due to human factors, which may affect the service life of pipes. Mark the pipeline position after concealed laying to avoid damage to the pipeline by secondary decoration. Note 2: PPR is fragile at low temperature and needs to be kept warm in winter. PPR pipe 5 ℃

PPR domestic pipe and PE pipe can be used as drinking water pipe materials, but there are differences between the two. The high temperature resistance of PPR pipe is different from that of PE pipe. The instantaneous temperature of PPR pipe can reach 110 ℃, while that of PE pipe as drinking water pipe is generally about 60 ℃ - 70 ℃. Therefore, PPR pipe can be used as cold water pipe or hot water pipe, while PE pipe can be used as cold water pipe. The difference between PPR household pipe and PE pipe lies in the following points: 1. The difference between PE pipe and PPR pipe in terms of cleaning first of all, PE pipe and PPR pipe are almost the same in terms of cleaning and safety, but the product quality is related to the raw materials selected by the manufacturer. Whether the raw materials meet the specified requirements and standards directly affects the product itself. All qualified PE and PPR water pipe products are necessary

Home installed pipes can be said to be the popular water pipe materials in home installed at present. As early as the 1980s, the main domestic water pipe in China was galvanized pipe, that is, the kind of pipe used for gas or heating. This kind of pipe can only go through the exposed pipe, and its disadvantages are very obvious. It is very easy to rust and breed bacteria. Therefore, the country will prohibit this. If the old houses equipped with galvanized pipes are decorated or reconstructed, the main pipes will not be replaced generally. If the pipes are seriously aged or seriously rusted, a very large amount of work will be required. First, the property or water company needs to close the main valve. In addition, because it will affect water use, it is also necessary to coordinate the residents upstairs and downstairs and need their cooperation. After the 1980s, the aluminum plastic composite pipe replaced the galvanized pipe. This pipe is a multi-layer pipe, which is divided into three parts

Common domestic pipes include the following: direct head: when the length is insufficient, the direct head can be used to connect the two pipes, and attention should be paid to matching the size of the pipe. Elbow: It is used to connect turns. The common ones are 90 ° elbow and 5 ° elbow. Since the principle of laying water pipes is horizontal and vertical, 90 ° is generally used for elbows, and 45 ° will be used for some locations where 90 ° cannot be used. Tee: used when leading from one water pipe to another. Stop valve: It is used to open and close the water flow. There are two kinds of stop valve and double hot-melt ball valve. Pipe cap: used to temporarily seal the water outlet and remove it when installing the faucet. Crossing the bridge bend: two crossing water pipes can be staggered up and down. In addition, there are internal and external wires for the direct connector, elbow and tee. The internal and external wires are used to connect the tap, angle valve and other different types of water pipes,

The application field of home piping is very wide, and many industries are using pipe materials. Different industries have different characteristics, so they have different technical requirements. Pipe is a relatively mature product, and all industries have corresponding technical standards. To test the pipes, select the corresponding product standards according to the industry in which the pipes are used, and test the corresponding technical indicators according to the needs of the industry. Generally, it includes dimension index, inner diameter, outer diameter and wall thickness. Strength indicators: the strength indicators of pipes include radial compressive strength, namely ring stiffness, flexibility indicators, bending indicators, impact strength, etc. For pipes used for drinking water, there are technical indicators in terms of sanitation and water pressure resistance. There are also other technical requirements for the communication industry.

PPR home installed pipeline is more and more widely used in today's society, because its own advantages and characteristics make it occupy a very important position in the pipe industry. It is random copolymer polypropylene, which is what we call Type III polypropylene. It is obtained by random copolymerization of propylene monomer and a small amount of ethylene monomer under the action of heating, pressure and catalyst.
