If the PE pipe fails to connect or breaks during the hot melt connection operation,it indicates that the hot melt connection method is incorrect or the connection status of the water supply pipe is abnormal.At this point,it is necessary to stop continuing the hot melt connection and investigate the cause of the failure.Only after solving the problem can the hot melt connection continue,otherwise it will only lead to the inability to connect and the phenomenon of breakage.So what are the specific reasons that can cause the hot melt connection to break?
According to experienced construction personnel,the specific reasons for PE pipe fracture are summarized as follows:
1、It may be due to the use of different materials for the production of the pipes,and the incompatibility between the two materials,resulting in the fracture of the hot melt connection.
2、There are impurities at the connection point of the water supply pipe,which can cause uneven temperature at both ends during hot melting.
3、It is also important to note that heavy objects should not be placed on the water supply pipe before use,otherwise it may cause the pipe to rupture.Regular maintenance and upkeep of the PE pipe should be carried out during use.

Overall, the fundamental reason for the unsuccessful hot melt connection of PE pipes is that the preparation work before connection construction was not done properly, which led to the continuous failure of hot melt connection of water supply pipes. Therefore, it can be seen that whether it is hot melt connection or any other operation, preparation work must be done before construction to ensure that there are no problems before proceeding with the construction. Otherwise, it will only lead to continuous errors in the construction operation and affect the construction quality.
