Method for using steel wire mesh skeleton plastic composite pipe
After welding, make sure that it is cooled for more than 120 minutes before water pressure test.
Welding replacement of electric melting pipe fittings, must ensure that the pipeline without water retention, otherwise it is difficult to weld the fused pipe solid.
When the cut pipe or pipe fittings are connected with the original pipeline, the angle must be reasonable, no tension or other force can be avoided, and the electric welding pipe can be displaced during welding so as to leak water.
1, prepare tools: cutting machine, grinding machine, electric welding machine, steel ruler, mark pen, hammer, wood pad and replacement of pipes and pipe fittings fused.2, advance the water emptying pipe, tube or Water Leakage resection site fused fittings; then using the ruler to measure the length of the replacement parts, and then the interception of the same length of the tube, if you need to advance fused fittings, calculate the position and size, to avoid error.
