The hdpe pipe belongs to the green environmental protection pipe, compared with the traditional metal pipe, has extremely significant advantages, not easy to rust, corrosion resistance, non-toxic and tasteless. Therefore, it has become a substitute for the traditional metal pipe in drinking water pipes. fitting suppliers of HDPE pipe fitting suppliers is the most influential tool for pipe fitting suppliers.
First, the performance advantage of the hdpe tube
1, green environmental protection
This is one of the extremely outstanding advantages of the hdpe tube. Its production material is non-toxic and tasteless. The pipe made with it definitely has the nature of non-toxic and tasteless. This makes it safer to use without worrying about contamination of the environment and the liquid being transported.
2. Strong impact resistance
The pipe will be subjected to a certain external impact force during operation. If the bearing capacity is insufficient, the pipe is easy to be damaged, let alone put into use. The pipe will not break when subjected to some heavy pressure.
3. Excellent low temperature resistance
The pipe has a lot of use environment, whether it is elevated temperature or low temperature will have a certain impact on the pipe. In order to make the pipe better into the actual production, it is required to adapt to a certain low temperature and elevated temperature conditions. hdpe tube has excellent low temperature resistance, even in a very low environment will not appear brittle crack.
4. Slight friction coefficient
During the operation of the pipe, the pipe wall will be worn due to the influence of the conveying medium flow in the pipe. hdpe pipe wall flat, low flow resistance, so the fluid friction performance is excellent, not only wear-resistant and elevated transport efficiency.
5. Good flexibility
Plastic itself has a certain degree of flexibility, and compared with metal pipes, its plasticity is elevated. And hdpe this plastic pipe also has a unique flexibility and construction is more convenient.
Two, the pipe connection
1. Hot melt connection
This is the common connection method of hdpe pipe. The pipe is connected through the adjustment, heating, joint, pressure and cooling procedures of the pipe interface. During operation, the heating temperature should be paid attention to. It should not be too high or too low. The heating tool should be removed after melting. When applying pressure, it should continue for a certain time to cool down, so as to avoid affecting the connection quality of the pipe.
2. Socket connection
The connection mode is: first of all, one end of the pipe is welded and then reinforced, so that the remaining end is directly inserted in the pipe receiving port, but also sealed with rubber sealing ring, to enhance the sealing of the connection port.
3. But a welding connection
This connection method is extremely simple. Normally, additional tools or equipment are needed to connect the pipe. The butt welding connection does not need additional parts, it has a rigid connection, can not be disassembled, strong tensile resistance and so on.
4. Flange connection
This is a detachable connection, and its application is extremely wide. Numerous places that need to be connected with different types of pipes or fittings and equipment can be connected with flanges.
5. Wire buckle connection
This connection mode is not widely used and is suitable for the installation of some simple detachable connectors. Therefore, its application scope and scenarios are limited.
Three, the application field of a pipe
1, construction engineering: construction engineering is inseparable from the transport of water, including building foundation drainage pipes, household water or sewage discharge pipes, and additional building parts of the drainage or water supply system required to use the place.
2. Civil and public engineering: This aspect includes a wide range, because hdpe pipe has corrosion resistance, wear resistance and environmental protection characteristics, and is commonly used in water supply and drainage. On this basis, it has the unique electrical insulation property of plastic, so it can also be used in power pipes, telecommunication pipes and other protective pipes. The drainpipe can be used for sewers, slopes, railways, highways, bridges, tunnels and other places.
3, agricultural engineering: there are numerous places in agricultural engineering that need water, vegetation growth without water to irrigate, of course, but also to prevent the rain from flooding the vegetation. Therefore, hdpe pipe is also widely used in agricultural land drainage pipes and crop irrigation pipes.
The above is about the content of the pipe. The pipe is widely used, but we must consider it according to the actual construction and working condition in the application. Only by choosing the corresponding pipe can we ensure the normal work of the pipeline system.
