PPR pipe production line pipe connection using hand-held welding device for hot-melt connection. Before the connection, you should first remove the pipes and accessories on the dust and foreign matter. When the machine is lit and stabilized, it is aimed at the pipe (piece) DN <50 with hot melt depth of 1-2MM and DN <110. The hot melt depth is 2-4MM. When connecting, Inserted into the heating sleeve, to reach a predetermined depth. At the same time, without rotating the tube pushed to the heating head heating, to reach the heating time, immediately the tube and pipe from the heating sleeve and heating head at the same time removed, quickly without rotation, evenly inserted into the required depth, so that The joint forms a uniform flange.
In the specified heating time, just welded joints can be corrected, but is strictly prohibited to rotate. Pipe and pipe heating, should prevent excessive heating, so that the thickness of thinning. The pipe is deformed in the pipe fitting. In the hot melt intubation and correction, it is strictly prohibited to rotate. Operation site shall not have open flames, is strictly prohibited on the pipe with open flame bake. Will be heated after the pipe and pipe vertical alignment to push the force to light, to prevent elbow bending. After connecting, you must hold the tube and pipe to maintain adequate cooling time, cooling to a certain extent before the release.
