Compared with steel pipes, the construction process is simpler and has a certain degree of flexibility. More importantly, it does not require anti-corrosion treatment, which will save a lot of processes. The disadvantage is that it is not as mechanical as steel pipes. During construction, special attention should be paid to the safe distance of thermal heating, and it cannot be exposed to the air and sunlight. It is sensitive to chemicals to prevent damage caused by leakage of sewage pipes.

As a result, when two pipes are butt-jointed and installed, multiple bolts need to be tightened in sequence using tools. This is not only very troublesome to operate, but also very time-consuming and labor-intensive, affecting the speed of PE pipe butt-jointing installation. At the same time, the general PE replacement pipe has poor thermal insulation performance, and the interface is prone to freezing and cracking when the temperature is low, which greatly reduces the practicality of the pipe body when in use.

[0004] Therefore, the utility model provides a PE solid wall pipe assembly which is convenient for fixed connection to solve the above problems. Utility Model Content
