How to weld PP pipe? What's the difference with PPR welding?

PP pipe fittings are hot-melt sockets and should be welded by hot-melt welder. If it is hot-melt butt welding, it should be welded by hot-melt butt welding machine. If PP pipe fittings are socket type, they can be welded by plastic welding torch.

Different welding methods:

1, PPR welding: a welding process in which the workpiece is permanently connected by reaching the binding force between atoms or molecules by heating or pressurizing or both, with or without filler.

2.PP welding: it is a way to use exothermic flux chemical reaction as heat source to fix the ends of two workpieces to be welded in the mold in advance to produce high temperature to connect the workpieces.

Characteristics of PP tube:

1, no rust: PP pipe can withstand the corrosion of high concentration acid and alkali with PH value of 1 ~ 14 in a large temperature range.

2、? Wear resistance and no scaling: the inner walls of PP pipes and fittings are even and smooth, with small flow resistance and no scaling.

3. Reduce vibration and noise: PP pipe has excellent sound insulation performance, which can significantly reduce vibration and noise caused by liquid flow.

4. Anti-freezing crack: PP material has excellent elasticity, so that the cross section of pipes and fittings can expand with frozen liquid without cracking.

5, anti-condensation, less heat loss: PP material is a bad heat conductor, which can reduce condensation and reduce less heat loss.

6. Simple installation: PP pipe is light in weight, easy to install and operate, and has weldability.

7. Long service life: The service life of the PP pipe system is 50 years under the specified service conditions.
