The working principle of pp pipe is to install it under the heat preservation or cold preservation pipe rack as support and fix and then clamp the red pine block with a double bolt pipe clamp to make it more fixed on it, thereby increasing its overall stability.
PP pipe is also a kind of supporting air-conditioning product. It has strong anti-corrosion and anti-aging effects. It can play its role and value well when in use, because the cold energy of the cold insulation pipe may be transferred to the structural beam through the support base. Therefore, the installation of this product is to prevent the diffusion of cold energy, thereby creating a cold bridge, which plays the role of heat insulation, cold preservation, vibration reduction, or thermal expansion buffer. Therefore, it is more convenient to use, simple to install, and can meet people’s needs.


Pay attention to the following points when using the hot melt connection method:
The hot melt tool can be turned on to reach the working temperature, and the operation can be started after the indicator light is on;
When cutting the pipe, the end face must be perpendicular to the pipe axis. Generally use special scissors or pipe cutting machine to cut the pipe, if necessary, use a sharp hacksaw, but the burrs should be removed after cutting the pipe section;
The connecting end faces of pp pipes and pipe fittings should be clean, dry and free of oil;
When welding elbows or tees, pay attention to the direction according to the requirements of the design drawings and mark the position with auxiliary marks in the straight-line direction of the pipe fittings and pipelines;
When connecting, the tube end is guided into the heating jacket without rotating, and inserted into the standard depth. At the same time, push the tube onto the heating head without rotating to reach the specified mark.
After the heating time is over, immediately remove the pipes and fittings from the heating jacket and the heating head at the same time, and insert them directly into the marked depth, do not rotate, so as to form a uniform flange at the joint. The joint can be corrected at this time, but rotation is strictly prohibited.
After the specified cooking time is reached, the pipe sleeve is fastened to the pipe.
The key technology of hot melt connection is to control the heating temperature, heating time and cooling time, which is greatly affected by the ambient temperature and requires the operator to master the appropriate “degree”.
