Pb pipe in the pipeline when the construction, whether it is hot melt connection or flange connection, are the need to use some equipment and equipment.
The main equipment and equipment are pipe cutting tools, cutting shear, hand-held hot melt welding machine, welding head, base, timer, pencil and so on. And auxiliary tool materials are: power outlet, must have a safe reset over-voltage protection device, three holes with grounding protection welding equipment; alcohol / pure wood pulp paper, must use 95% alcohol and pure wood pulp paper, used Clean the welding surface. It is important to note that the three elements of welding are pressure, temperature and time, where the pressure causes the molecules to be squeezed together; the temperature melts the material in order to open the molecular chain; the time is the heating time and the cooling time.
In the use of these devices at the same time, we should pay attention to the use of methods and rules, so as to avoid operational errors and other issues.
