Electrofusion fittings need to pay attention to the problem:
1. First, in the process of installation, no organic matter or contaminants can occur on the inner wall and the fusion zone of the electrofusion tube. At the same time, during the welding process, a certain distance must be maintained to avoid unnecessary damage.
2. The field of fused pipe fittings needs to be located under the frozen soil layer. It should be noted that during the installation and welding process, the pipes cannot be soaked in water;
3. In the harsh environment where the temperature difference between day and night is relatively large, it is necessary to select centralizers and other pipe materials in a timely manner so as to avoid the principle of thermal expansion and contraction and affect the quality of the final welding; at the same time, if the temperature is extremely low, Do insulation measures to avoid unnecessary losses;
4. the final is in the process of pipe cooling, can not move freely.
In general, we have to pay attention to all kinds of details in the installation process so that we can improve the use of fused pipe fittings.
