General Information

The ZHTN-1200/400 welding machine is used for the production of PE and PP branch tees and interceptors in the following diameter ranges: main pipe Ø450 - Ø1200 / outgoing pipe Ø90 - Ø400. The ergonomic design additionally enables the device to be used for butt-welding of branch tees in existing PE pipelines directly at the construction site. The equipment is clipped to the main pipe (pipeline) with transport straps. In the next step, the oxidised layer in the area where the connection is to be made is removed using a scraper. In the area thus prepared, the drilling unit of the device drills a hole. Next, the appropriately cut outgoing pipe in the diameter range Ø 90 - Ø 400 is clamped in the moving jaw of the welding machine. The saddle shape required at the pipe end can be produced using the saddle shape clamping device type UZKN-1200/400. Then a special heating matrix dedicated to the specific diameter combination of the trunk pipe and the outgoing pipe attached to the heating plate heats up the sides of the trunk pipe and the cut end of the branch pipe. Once the material has heated up and the plate has been removed, the outgoing branch pipe is reheated. The unit operates in semi-automatic mode (calculates times and pressures, monitors the sequence of stages and records the parameters of the completed connection). The unit is supplied with drills and heating dies as agreed with the customer.
