LHY 1600 Hydraulic Butt Welding Machine

LHY1600 CNC controlled hydraulically operated butt-welding machine, suitable for HDPE & PP pipes and fittings from 1000 to 1600mm. This butt fusion welding machine has simple operation using CNC control through a mobile tablet, and extremely strong construction exhibits in PE pipe systems. Welding immediately according to ISO9000 low-pressure standard, including 10000 + welding data records. Excellent design and construction provide high-quality machines for field and factory welding. Welding can be carried out between clamps 3 and 4 for the tee, elbow, and manifold operation. All hydraulic devices are located on the main welding frame of the hydraulic butt welding machine.

HDPE butt fusion steps

1. The two PE pipes to be installed and connected are placed on the hdpe butt fusion machine clamp at the same time (the clamp can be replaced according to the diameter of the pipe to be installed), and the other end of each pipe is supported to the same horizontal plane with a pipe bracket.

2.  The end face of the pipe is cut flat with an electric rotary knife to ensure that the contact surface of the two pipes can fully match. Then the electric heating plate is heated to 210 °C, placed in the middle of the end faces of the two pipes, and the hd pipe joint machine is operated so that the two end faces are fully heated in contact with the electric heating plate at the same time.

3. After the heating meets the requirements, remove the heating plate and operate the butt welding machine hydraulic device again to fully dock the end faces of the two melted pipes and lock the hydraulic device in order to prevent rebound.

4.  During plastic fusion welding, pipe crimping thickness and docking time should strictly meet the material process requirements, generally can also refer to the technical parameters and specification requirements provided by butt welder manufacturers.
