How PP-R hoses should be properly installed

PP-R water pipe has become the primary choice for today's renovation, but many people may not understand the installation method of PP-R water pipe. Here is a brief introduction:

1. Keep the fusion parts of electrofusion fittings and pipes free from moisture.

2. The connecting surfaces of pipes and fittings must be kept dry, clean and free of oil.

3, cutting the pipe must make the end face perpendicular to the pipe axis. Pipe cutting or pipe cutting machines are generally used for pipe cutting. If necessary, sharp hacksaws can be used. However, cutting of the pipe section should remove burrs and burrs.

4, hot-melt tool power, reach the operating temperature green indicator light can start operation

5. When heated, the end of the tube is introduced into the heating jacket without rotation and inserted into the marked depth. At the same time, the tube is pushed onto the heating head without rotation to reach the specified mark. The heating time should be performed according to the welding tool instructions.

6. Immediately after the heating time is reached, the pipe and fittings are removed from the heating mold at the same time, and they are quickly inserted into the marked depth without rotation, so that a uniform flange is formed at the joint.

7. In the specified time, the just-welded joints can be corrected, but they must not be rotated.

8. When welding elbows or tees, according to the requirements of the design drawings, attention should be paid to the direction. In the straight direction of the pipe fittings and the pipe, use the auxiliary signs to mark the position.

9. The standard heating time of the fused connection should be provided by the manufacturer and should be adjusted with the ambient temperature.

10. When the pipeline is installed, it shall not be bent. When passing through the wall or floor, it shall not be forced to correct. The net distance shall be greater than 100mm when laying with other metal pipes, and the polypropylene pipe shall be inside the metal pipe.

11. The indoor surface mounted pipeline shall be completed after the civil construction is finished. Before the installation, the hole shall be properly reserved for the civil construction. The size shall be 50mm larger than the outer diameter of the pipe. When the pipeline passes through the floor, a steel casing should be installed. The casing rises 50mm above the building (ground) surface.

12. When the pipeline crosses floors and roofs, strict waterproof measures shall be taken. Fixed brackets shall be installed on both sides of the crossing points.

13. Concealed pipelines underneath the floor surface and inside the wall should be well accepted and recorded for hydrostatic testing and concealment works.

14. When the pipeline is wearing the foundation wall, metal casing should be set to make your installation more secure.
