Plastic pipes represented by PPR pipes have been widely used in daily life, occupying more than 80% of modern water supply and drainage pipes. Take PPR pipes as an example. The products produced by PPR pipe manufacturers are generally 4 meters each. Correspondingly, PPR pipes are corrosion-resistant, hygienic, and have excellent materials, but they cannot be bent. It is inevitable to use pipe fittings in pipeline installation and use. Connection, the common connection method of PPR pipe fittings.
When PPR pipe manufacturers produce pipe fittings, each type of pipe fitting is used in conjunction with pipeline installation. Different pipe fittings are used for connection in different construction environments. Common PPR pipe fitting connections have the following types:
1. PPR pipe coupling
Because the length of PPR pipes is limited (the PPR pipes produced by conventional PPR pipe manufacturers are each 4 meters long), PPR pipe coupling needs to be used for connection at this time;
If we need to connect PPR pipes of different sizes, we need to use reducer coupling
2. PPR fitting Elbow
The elbows include PPR 90° elbow, PPR 45° elbow, reducer elbow, union elbow, PPR FITTING FEMALE ELBOW(COPPER THREAD), PPR FITTING MALE ELBOW(COPPER THREAD), etc. When the pipeline waterway needs to be turned, then the elbow is sent Used
3. PPR fitting tee and cross
In the home and engineering decoration, we sometimes need to divert and change the direction of the waterway. At this time, we need to use TEE and CROSS connections, which can connect water pipes in different directions;
4. PPR FITTING FEMALE COUPLING(COPPER THREAD) AND PPR FITTING MALE COUPLING(COPPER THREAD)
When connecting with household faucets, water meters, and other water-using devices, due to the design of the water-using instrument, it is necessary to use the PPR FITTING FEMALE COUPLING and PPR FITTING MALE COUPLING for connection. Usually, most of the PPR FITTING FEMALE COUPLINGS are used in home decoration. It is necessary to remind everyone here that the price of wire connectors is usually more expensive, and we should try to reduce the number of connectors used;
5. PPR Ball valve and PPR STOP valve
Ball valves and shut-off valves are what we usually call water valves, which are used to activate and close the waterway. Ball valves are mostly used in home furnishings, and stop valves are mostly used in engineering and construction; in china, ball valves are used more in the south, and more stop valves are used in the north;
6. PPR over bend
The use of twisting is to use two cross but not connected water pipes, and its function is to facilitate the installation of disjoint water pipes on the same horizontal plane;
7. plug and end cap
The function of the plug is to block the temporarily unnecessary ports in the pipeline to play a sealing role, and it is removed when installing water faucets and other water instruments.
Conclusion: There are many ways to connect PPR pipe fittings, and they should be designed reasonably according to the requirements of the construction environment. At the same time, it is inevitable to avoid hot melting during connection. Pay attention to the hot-melt connection of PPR pipes and fittings to ensure the quality of the connection, prevent repeated construction, and waste manpower and material resources.
