When pvc fitting many users choose PE water supply pipes, because they don't know enough about it, they are often easy to choose the wrong one. They don't know whether to use ppr pipes or poly pipes for water supply projects in construction. What is the difference between the two. PPR pipe is an ideal pipe for drinking water pipes, but it is not as good as indoors in the outdoor environment. PE water supply pipes are used, which is also the ideal material for the main water pipe.The main chemical molecular component of PE water supply pipe is high-density polymer. Anyone who understands organic chemistry knows that the product is composed of two carbon atoms and five hydrogen atoms, and one of the hydrogen atoms is combined with carbon atoms by a double bond. The single molecule is polymerized in a certain way, and such a product is a high-density polymer product.The main component of the PPR water pipe is polypropylene, that is, three carbon atoms are combined with seven hydrogen atoms, and there is also a double bond between a hydrogen atom and a carbon atom, and the product formed by polymerization is a polypropylene product.

Both products have their own advantages, and the scope of application is quite wide. Of course, we still need to choose according to our own needs.We have a set of standards to test whether the PE gas pipe meets the requirements. Let's take a look at the following for details. 1. The inspector must inspect each roll of PE gas pipe delivered by the operator. The inspection items include dripping conditions, pressure, wall thickness, unit weight, width and narrowness. The length taken during the test shall not be less than 5 meters, and the number of samples for each roll shall not be Less than once.The inspector must carry out a rewind inspection of the PE gas pipe delivered by the operator. The inspection items include appearance, irregular shape, fullness of the labyrinth, number of joints, joint bundling conditions, number of meters. The quality inspector must record the various data of the random inspection product, including the long-distance drip test, and the recorded data must be true and must not be altered.


During the pressure test, the pressure of the PE gas pipe should be adjusted to see if the dripping is even, and the pressure can be tested after the dripping is normal. The pressure should not be lower than, if it is lower, another section should be taken for the pressure holding test , Keep the pressure in still water for 1 hour. As the application level of PE gas pipes becomes wider and wider, users have higher and higher requirements for their quality.PE water supply pipes need to be socketed in daily use, so what is the socket connection sequence and operation method of this material? In order to facilitate your operation and use, the following article will explain this aspect in detail. The socket connection steps of this kind of PE water supply pipe are: pipe cutting: the connection end of the pipe is required to be cut vertically to ensure that there is enough hot melt area .The performance characteristics of the silicon core tub the silicon core layer on the inner wall is solid, and the silicon core layer on the inner wall is simultaneously extruded into the high-density poly pipe wall, and is evenly distributed throughout the inner wall of the pipe without peeling or detaching.


The same life as the silicon tube; the characteristics of the inner silicon core layer remain unchanged, and the cable can be drawn repeatedly in the pipeline; the inner silicon core layer does not react with water, and water can be used to flush the pipeline after an accident.The above are the points that need to be paid attention to during the construction of plum blossom pipes. The construction is strictly in accordance with the construction to ensure safety and complete the project schedule. The silicon core tubes and general materials used in the project must have product qualification certificates and product records submitted by the manufacturer. Silicon core tube inspection content includes quantity, appearance, size specifications, physical and chemical properties; silicon core tube connector and other accessories inspection content includes quantity, appearance, size, air tightness, durability, physical and mechanical properties; steel pipe iron fittings and other materials inspection content There are appearance, size, rust prevention.
