What are the advantages of traditional fittings over PE electrofusion fittings?

With the accelerated pace of technological progress, the continuous emergence of new processes, new materials, new technologies to make pvc fittings relative to the traditional pipe fittings advantages are becoming more and more obvious, then PE electrofusion fittings and traditional fittings (such as metal pipes, cement pipes, etc.) compared to the end of what is different?

What are the advantages of traditional fittings compared with PE electrofusion fittings?

Their differences are mainly expressed in the following aspects:

    First, PE electrofusion pipe fittings impact resistance, tensile strength compared to traditional pipe fittings better;

    Second, the specific gravity of PE electrofusion fittings is small, in general, is one-sixth to one-tenth of the metal pipe;

    Third, PE electrofusion fittings corrosion resistance is stronger;

    Fourth, PE electrofusion fittings of the friction coefficient is small, fluid resistance is small;

    Fifth, PE electrofusion pipe fittings are simple to install and easy to transport;

    Six, PE electrofusion pipe fittings service life than the traditional pipe fittings a little longer, can reach thirty to fifty years.

It can be seen that in the long time after, pvc pipe fittings and other pipe fittings than, will be more advantageous.

Secondly, PE electrofusion pipe fittings in the installation also have some need to pay attention to:

1. Installation of electrofusion pipe fittings and pipe fusion area of the inner wall is strictly prohibited organic and other substances contamination.

2. Welding fittings must be away from the welding fittings until the completion of the welding cooling 30S before approaching.

3. According to the temperature of the site environment and the working voltage changes. The welding time can be appropriately compensated during welding.

4. According to the requirements of the electrofusion welding machine to enter the matching power supply, the farther away from the power source electrofusion welding machine, the larger the diameter of the power cord is required to avoid undervoltage affecting the quality of welding.

5. Pipe installation, elbow, tee fittings must be good pier reinforcement or bracket fixing and proper pipeline compensation.

6. Pipe landfill must be below the permafrost layer, pipe trench in the installation and welding can not have water soaked pipes.

7. When the temperature is low, welding electrofusion pipe fittings must do a good job of insulation.

8. Work in the environment of a large temperature difference between day and night, must be used to support the corrective device and other tools to fix the pipe on both sides of the electrofusion fittings, so as not to be affected by thermal expansion and contraction of the welding quality.

9. In the cooling process, can not move the pipe and fittings.

Of course, there are many different specifications of these pipes, specific specifications of how to use can consult the electrofusion pipe fittings manufacturers.
