Can pe pipe and ppr pipe be hot melted?
Yes, but not direct fusion. For PPR pipe, it can be hot-melt connection, but if it is connected with PE pipe, it cannot be directly hot-melt connection.
Many people know that these two kinds of pipes are connected by hot melt and think they can be connected. But in reality, this approach is wrong. Even if they are hot fused together, there is no guarantee that water will not leak later because the molecular mechanisms of the two tubes are different, even though they appear to be connected on the surface. together, but without actually any adhesion.
The correct method is: pipes with thick mouths can be connected with flanges, and small-diameter PE pipes at home can be butted with pipes with outer or inner wires, so that the connection is effective. to ensure its engineering quality.
How to connect PE pipe
The connection methods of PE pipes are generally divided into four types: hot melt connection, saddle butt, steel-plastic flange connection and electrofusion connection. The most common method is thermal bonding. A hot melt connection is to use a hot melt butt welder to heat the pipe ends. After the pipe end is melted, it is quickly attached, maintaining a certain pressure, and cooling to achieve the purpose of welding.
