The cut must be flat when the PPR pipe is hot melted

The cut of the PPR pipe should be flat, clean and free of burrs. If the pipe cut is skewed, the pipes and fittings are likely to be out of line during welding, and the welded PPR pipe will not be straight. Moreover, the overlapping lengths of the PPR pipes and fittings in the joints are inconsistent. When the water flows through, it will have a certain impact on the hot melt joints and shorten the life of the joints.
