PPR pipe has the advantages of energy saving and material saving, environmental protection, light weight and high strength, corrosion resistance, smooth inner wall without scaling, easy construction and maintenance, and long life. Fluid transportation, agricultural irrigation and other construction industries, municipal PPR pipes are extruded into pipes with random copolymerized polypropylene, and then injected into pipes. the

The connection method of PPR pipes is emergency hot-melt connection, but if the hot-melt connection operation method is not good, even if a good pipe is selected, it is difficult to ensure the quality of the installation and the quality of the connection. First, you need to choose the hot melt adhesive that matches the manufacturer. , The heating time and heating temperature of the heat welding machine need to be strictly implemented in accordance with the operating procedures.

Since the 20-63mm PPR fittings is connected by thermal fusion, the connection between the pipes can only be used once. Therefore, when the water supply branch pipe is concealed in the wall, it is necessary to accurately provide materials according to the planning requirements and the specific environment of the construction site. In some cases, in order to reduce the interface of the buried part, it is necessary to make it thinner.

PPR pipes need to be carefully cleaned of oil, impurities and burrs on the pipe and surface before welding; the length of the pipe that is too thin to insert into the pipe needs to be appropriate, and the jointed pipe needs to form a uniform flange at the research point. If it is not uniform, one side should be stable. Insufficient welding, its research is difficult to guarantee to avoid water leakage, in this case, it needs to be reconnected immediately.

The connection between the PPR pipe and the pipe should adopt the method of thermal welding. It is not allowed to directly wind the wire on the pipe and the pipe. It can be connected with the metal pipe with the flange. The connection with the water spray pipe needs to use a pipe with a metal insert; in order to ensure the welding Quality, construction requires the use of reliable quality fusers.

Use special scissors to cut off the pipe vertically, smooth and free of burrs; use a pencil to insert the pipe and pipe indicating the depth of welding on the pipe into the cladding device, and heat according to the specified time; after heating, take out the trachea and trachea, and connect them immediately. The timing of the connection of the trachea and the trachea, if the two are not in the correct position, a small amount of adjustment can be made within a certain period of time, but the rotation angle cannot exceed 5 degrees; After reaching a certain level, release the hand and decorate the next trachea continuously.

Several characteristics of PPR coupling wholesale

1. Non-toxic and healthy. PPR pipes only contain carbon and hydrogen, and there are no harmful and toxic elements. It is not only suitable for cold and hot pipes, but also for pure drinking water systems.

2. Good heat resistance. The Vicat softening point of the PPR pipe is 131.5. The working temperature can reach 95. It meets the requirements of the hot water system in the "Code for Water Supply and Drainage in Buildings".

3. Heat preservation and energy saving. The thermal conductivity of PPR pipe is 0.21W/MK, which is only 1/200 of that of steel pipe.

4. Long service life, the operating temperature of PPR pipe is 70. Operating pressure (P.N) 1. Under OMPA conditions, the service life can reach more than 50 years; the service life at normal temperature (20) will reach more than 100 years.
