UPVC water pipes and steel pipes, construction technology is simple, there is a certain degree of flexibility, but more important is not used for preservative treatment, will save a lot of processes. Disadvantages of the device than the steel pipe, the construction of special attention to the safety of heating space, and can not be exposed to the sun in the air, and sensitive to chemicals to prevent the leakage of sewage pipe damage.

1, cleaning pipe end;

2, the pipe clamped in the welding equipment, the use of double-sided dressing machine repair two welded joints face;

3, remove the dressing equipment, through the propeller so that the two ends of the contact, check the consistency of the two surfaces, strict control to ensure correct end;

4. Insert a hot plate at 210 ° C between the end faces to push the tube at a specified pressure to press the tube end on the hot plate and form a uniform fused beam (annular projection) around the two tube ends,

5, once the completion of heating, the rapid removal of the heating plate to avoid the heating plate and the melting end of the pipe friction;

6, with the specified connection pressure will be pushed into the two ends of the combined to form a double-edged melting beam (flanging on both sides, inside and outside the flanging of the annular bulge) fusion welded joints cooling at least 30 min.
