LHY 1200 Hydraulic Butt Welding Machine

LHY1200 Hydraulically operated Butt-welding Machine, suitable for PE and PP pipes and fittings from 630 to 1200mm. This hydraulic butt welding machine is the result of continuous participation in the PE pipe industry for many years, providing high-quality machines for field and factory welding. The use of original aluminum castings and German hydraulic seals can achieve lightweight without affecting strength and performance. Welding can be carried out between clamps 3 and 4 for the tee, elbow, and manifold operation. This butt fusion welding machine can be integrated with an optional data logger and overhead electric crane.

How does electrofusion welder work?

The electrofusion welding machine for hdpe pipe provides the electric energy needed for the heating coil. When the coil is electrified, the material adjacent to it melts, forming an expansion pool in contact with the surface of the pipe. The continuous introduction of heat energy will lead to the melting of the pipe surface. At the end of the thermal cycle, the pipe fittings and pipes will cool, and the melted material will solidify and form a good joint.

Hot and cold areas, the length of these areas is particularly important. The electrothermal fusion welding machine electrifies the electric melting zone and heats up the electric heating wire in the electric melting zone. The heat energy melts the surface of the pipe and pipe fittings, and then the plastic pipe together according to cold fusion welding. Each area ensures that the melting is controlled to the exact length of the connector socket, and the pitch and positioning of the coil relative to the inner surface of the socket are precisely controlled, ensuring a uniform heat distribution.

Classification of Hydraulic electrofusion welding machine

The main results are as follows: 1) the pipe fusion welding machine is used for the electric fusion welding of PE and PP electric fusion fittings. it is a kind of adjustable voltage source, which can meet the welding requirements of different electric fusion pipe fittings.

2) Tropical electric fusion welding machine this kind of electric fusion welding machine is used for PE electrothermal fusion welding, its output adopts useful value constant current output, and is mainly used for non-pressure PE and PP straight pipe or bellows electric fusion welding.

Plaswelding is a professional  butt welding machine manufacturer, and we can provide various kinds of electrofusion machines in good price, to meet your needs in all kinds of industries.
