How to connect PE pipe and PPR pipe and melt them directly? What’s more, the specifications and models of the two pipes are the same?
The PPR pipe and PE pipe should not be connected by hot melt. The PPR Female Adapter should be directly connected with the PPR Male Adapter.
The wall thickness of PE tube is different from that of PP-R tube. The bonding strength of the two materials cannot meet the requirements. PE is connected with pp-r after being introduced into the room, and the small pipe diameter is converted to metal and the large pipe diameter is converted to flange. Cast iron pipe and steel pipe in the outdoor flange conversion, flange shaft with soft repair easy to replace.
The PPR tube can be connected by hot melt, but not by hot melt. If you want to connect them together, you can add a pipe joint in the middle to connect the two pipes.
The correct method of connection is to use flange for connection, and small diameter pipe can also be connected with toothed accessories, so as to effectively guarantee the connection strength and ensure the engineering quality.
Flange connection is to fix two tubes, fittings or equipment, respectively on a flange, and then add a flange pad between the two flanges, and finally bolt the two flanges tension so that it closely together a removable joint.
Flange connection is mainly used for the connection of cast iron pipe, rubber liner, non-ferrous metal pipe and flange valve, etc.
PE pipe and PPR pipe connection is reliable: the PE pipe system is connected by electric hot melt, the strength of the joint is higher than the strength of the pipe body. PE tube has better impact resistance than PPR tube: the low temperature embrittlement temperature of polyethylene is very low, which can be used safely in the temperature range of -60-60℃. During winter construction, due to the good impact resistance of the material, the pipe will not crack. The stress cracking resistance of PE tube is better than that of PPR tube: HDPE has low notch sensitivity, high shear strength and excellent scratch resistance, and excellent environmental stress cracking resistance. PE pipe is more resistant to chemical corrosion than PPR pipe: HDPE pipe is resistant to a variety of chemical medium corrosion, the presence of chemicals in the soil will not cause any degradation of the pipe. Polyethylene is an electrical insulator, so it will not decay, rust or electrochemical corrosion; Nor does it promote growth of algae, bacteria or fungi.
