Can the pE composite pipe be cooled by electric fusion?
The pipe cannot be connected during cooling. Some sites will rush period tight, connecting pipe and welding at the same time, this is a very wrong way of construction, pipeline welding must ensure that the entire pipeline are connected, can operate welding, not in front of the connecting pipes, behind welding.
Non removable tread. This is a very important point, because the electric melting pipe with pipe welding, the contact surface has melted, must pass through the cooling process make it solidified into a whole, in this process, if the mobile pipeline or stampede will cause the weld, weld gap and so on, easy to cause the pipeline to Water Leakage.
Cooling time is more than 2 hours. When the wire mesh frame plastic composite tube after welding, must have at least the cooling time of 2 hours, this link can not be omitted, but also to ensure the cooling time must be more than 2 hours, but other aspects of the construction. If it is summer, it is recommended that the time be extended.
No water can be injected into the pipe during cooling. This is generally encountered in pipeline maintenance, owners eager to supply water, electric melting pipe welding is just good, let the cooling water directly, this method is not very scientific, pipeline after water injection will make the pipeline pressure, and just welded wire mesh frame plastic composite tube well is not completely by internal cooling the pressure will make the welding part again Water Leakage
