For PE pipe connection is how much connection mode, really can not find their own suitable, to understand how to carry out welding PE pipe!
I. Preliminary preparation for PE pipe welding: check whether the switching power supply of the hot melt welding machine is connected, whether the turning tool can be drilled, whether the heating plate is heated, and whether the frame cylinder is operated.
Two, welding:
(1) Eliminate the waste (oil, dust, mud, water) at the port number of the pipeline.
(2) Place the PE tube in the frame slip.
(3) Mill the PE pipe port with milling cutter disk.
(4) Accurately measure the driving force of the frame cylinder support.
(5) Check whether the temperature of the heating plate is in the middle of the temperature value 190-230, and the normal temperature is 210±10℃.
(6) Put the heating plate into the frame.
(7) Reduce the working pressure of melting (0.02Mp).
(8) Convert immediately after the time limit is reached.
(9) Increase the working pressure so that it reaches a certain level, generally 2-3Mp, depending on the driving force of the cylinder support.
(10) To carry out pressure test refrigeration. |
