You are not allowed to lay down the jointed pipes on the ground after fusion welding. The jointed pipe should stay in the machine with/without pressure (according to different welding norms) until the cooling time ends.
The proper cooling time varies depending on the pipe material, pipe diameter, and wall thickness. You could always find the cooling time from MM-Tech operation manual for butt fusion welder.
It varies depending on the pipe material and welding norms. Please consult the pipe manufacturer’s recommended parameters.
Drag pressure is the pressure to overcome the friction during machine carriage movement. It should be added to the total fusion pressure.
You are always requested to measure the drag pressure with pipes stayed in the machine. Simply speaking, completely open the machine carriage, zero the pressure in the hydraulic system, close the pressure relief valve, then push the direction lever to maximum and gradually rotate the pressure regulated valve in a clockwise way until the machine carriage gets in motion. The current pressure shown on the gauge is the drag pressure. For more details, please refer to MM-Tech operation manual for butt fusion machine.
Before butt welding, the pipe ends must be rounded and aligned. A pipe roller support will give more help in alignment and reduce the drag pressure. When the mismatch of the pipe walls is still out of local regulation, please adjust the clamping jaws by tightening down the high side until the pipe ends are even.
Replacing the blade not depends on a certain period. But you should replace it when two sides of the blade are blunt or chipped. The life of blade varies depending on the hours of operation, material being face, periodical maintenance, etc.
