What do you need to do before using hdpe jointing machine?

1. The temperature control must be correct. The hot melt welding temperature of hdpe jointing machine is 253℃-274℃. If the temperature is lower than 253℃, the pipes and fittings will only melt on a thin surface layer. Once they are welded, the strength of the weld cannot be guaranteed. This is what we usually call the phenomenon of false welding; If the temperature is higher than 274℃, the surface molecules of the pipes and fittings will be destroyed by the high temperature, which will cause the PP-R to form a thin liquid

After the connection, the inner diameter of the pipe will become smaller. More importantly, the connecting part of the hdpe jointing machine will be brittle, especially when the pipeline system is fully completed and pressurized. Such problems often occur.

2. The constant temperature time should be long. The length of the constant temperature time of hdpe jointing machine is one of the important signs of the performance of hot-melt welding equipment. There is still a problem of heat consumption for hot melt equipment after heating up to the set temperature. Especially in winter, the heat consumption at the tuyere, even in the non-operating gap, is also very large, and once it is in operation, its pipes and fittings All are consuming heat energy separately, which requires hdpe jointing machine to have strong heat energy storage capacity and timely replenishment capacity.

What are the possible problems that may be encountered in the use of hdpe jointing machine?

It should be said that the piping system for construction operations strictly in accordance with the requirements of the welding process and welding technology, there will be no problems when used under normal temperature and pressure. However, we often find that bursting or blisters occur at the joint of the hdpe jointing machine during daily construction.

The main reasons are as follows:

1. The temperature of hdpe jointing machine is incorrect, too high or too low, which will change the properties of polypropylene;

2. hdpe jointing machine The surface of the welding sleeve has not been treated well, or the surface coating has fallen off, causing blisters in the contact part of the pipe;

3. The size of hdpe jointing machine is wrong, and the design is wrong, which makes the melting depth of the pipe and the welding structure inappropriate;

4. The welding surface of the pipe was not cleaned before hdpe jointing machine;

5. The pipes and fittings of hdpe jointing machine are not kept concentric or straight.

What is the reason for choosing hdpe jointing machine?

1. The hdpe jointing machine is not affected by the magnetic field (arc welding and electron beam welding are easy), and can accurately align the weldment. 　　

2. The hdpe jointing machine can weld two metals with different physical properties (such as different resistances). 　

3. The hdpe jointing machine does not need vacuum or X-ray protection.

With the increase in market demand, the types of hdpe jointing machines are also expanding. To meet these growing demands, WELPING Co., Ltd. has various hdpe jointing machines and they are all more effective, reliable, and consistent.
