Hot melt connection method of PE-RT plastic pipe and the matters needing attention
In the specified processing time, the newly welded joint can be adjusted, but no rotation.
When the heating time is reached, the pipe and the pipe are removed from the heating sleeve and the heating head at once, and the rapidly rotating straight line is inserted uniformly into the marked depth, and a uniform flange is formed at the joint;
When the connection is made, the pipe end without rotating is inserted into the heat sleeve to be inserted into the marked depth, and at the same time, the pipe fittings without rotating are pushed on the heating head to reach the designated mark. Heating time should meet the requirements of the above table (also according to the provisions of the manufacturer of hot melt tools);
When welding elbow or three way, according to the design drawing requirements, should pay attention to the direction, in the pipe fittings and pipe in the straight direction, with auxiliary sign mark its position;
1 hot melt tools connected to the power, to reach the working temperature indicator light, you can start the operation;2 cutting pipe must be made perpendicular to the end of the pipe line. The general use of the pipe or pipe cutting shear pipe cutting machine, if necessary, use a sharp saw, but after cutting the pipe section should remove burrs and burrs;3 the end face of pipe and pipe must be clean, dry and oil-free;4 use calipers and suitable pens to measure and mark the depth of hot melt at the end of the tube.
