Analysis of Henan PE pipe fittings repairing the damaged pipe network

If PE pipe fittings are used to repair some corroded pipe sections, PE pipe fittings shall be connected with steel pipes or cast iron pipes. In the construction process, after the PE liner penetrates into the pipe and is rounded, flange crimping can be used, or hot melt welding can be used to connect its end with the repaired pipe. http://www.sdpegj.com

Flange crimping is to weld the steel flange on the pipe end first, then heat the PE liner pipe at the steel flange mouth to flan, and then press the two steel flanges together with bolts http://www.zbpeg.com Used for low pressure pipeline. Hot melt welding is to pre wrap the electric wire on the electrothermal melting pipe fitting. When connecting the PE liner, the electric wire will be electrified and heated to melt the pipe fitting and PE liner at the same time. After cooling, the two will be fused together to achieve the purpose of connection and sealing.
