The reason why the electrofusion tube is peeled off

Ningbo Lianda Plastic Pipe Co.,Ltd | Updated: Oct 22, 2018

       The electrofusion tube means that the electric fuse is added to the mold in advance, and then the injection molded tube is mainly used for the connection of the steel mesh skeleton plastic composite pipe and the PE pipe in a special environment. And this article mainly introduces it in the process of use. The reason for the falling off of the electrofusion tube.

       First, observe the disconnected electrofusion tube and the pipe joint. Under normal circumstances, the inside of the electrofusion tube should melt and expose the electric fuse, and the outer surface of the pipe will melt and solidify. So look carefully at the pipe and the electrofusion pipe. The joint is the only way to find the problem of the fused tubing off. When observing the joints, the main causes of the shedding problem are as follows:

       1. The ports of the two pipes are not at the center of the electrofusion fitting. To put it simply, when the pipe is connected with the electrofusion tube, the connection is large and the connection is small, so that the connection between the two pipes is not located at the center of the pipe, and the other pipe is not firmly connected, thereby causing the electrofusion pipe to fall off.

       2. The pipe or electrofusion pipe is not polished. Grinding is an important step that must be required for steel mesh skeleton plastic composite pipe and electrofusion pipe fitting. Its main purpose is to remove the pipe and pipe fittings, the oxide layer which interacts with air during the production process, and better connect the pipe and the electrofusion pipe fitting. .

       3. Welding problems. If the construction personnel are not properly operated during the welding process, such as too long welding time or too short time, the electrofusion pipe fittings will not be firmly connected to the pipe, and the pipe fittings will fall off.

       4. There is dirt on the joint between the pipe and the electrofusion pipe. If the connection process, the pipe or the pipe joints are dirty, the connection will be weak and the electrofusion pipe will fall off.

       5. There is a problem with the quality of the product. Normally, according to the construction specifications, the electrofusion pipe will not fall off. In this case, there may be a problem with the quality of the product. We should promptly send the inspection to the professional department to ensure its legality. The rights are not infringed.

       6, improper suppression. If the operation is ok, the quality of the product is no problem, then you should carefully check the pressure equipment and the pressing process, such as pressure gauge problems, pressure failures, etc., will cause the electrofusion pipe parts to fall off.
