2. Non-toxic, good toughness, high impact strength.

3. Good insulation, wear resistance and chemical corrosion resistance.

4. Good heat insulation, medium flow resistance is small.

5. Laying is convenient and economical, safe and reliable

 

Precautions for construction of PE pipe fittings:

PE pipe fittings are an indispensable part of PE pipe construction, and the connection between pipes and PE pipe fittings is particularly important.

1. When splicing in cold weather (less than -5 degrees) and windy environment, maintenance measures should be taken or the splicing process should be adjusted.

2. Corresponding special heating machines should be used according to different interface methods, and open flames should not be used to heat pipes and PE pipe fittings!

3. Pipes and fittings of the same brand and matching performance should be used for the pipes that have been fused and connected. Pipes and fittings with similar performance must be tested and qualified before the construction can be stopped.

4. Before connecting PE pipes and pipe fittings, PE pipes, PE pipe fittings and facilities and equipment should be inspected according to the design requirements, and the inspection should be carried out before the construction site. Only when the pipes and fittings meet the requirements can the construction and operation begin. The main inspection items include product pressure rating, surface quality, matching product quality, etc.

 

Advantages of HDPE electrofusion fittings:

1. The electrofusion process is fully automated, and the operation is simple and safe.

2. Good hygienic performance.

3. The strength of electrofusion welding is high, which essentially guarantees the identity of the interface material and structure of the PE pipeline system and the pipe itself, realizes the high integration of pipe fittings and pipe materials, ensures no leakage at the interface, reliable connection and no hidden dangers, and is very durable grind.

4. Good corrosion resistance, long service life

5. Small friction coefficient and low resistance

6. Good flexibility and scratch resistance

7. Good ability to resist crack expansion

8. Good welding ability

9. Low installation cost, high efficiency and stable quality

10. The installation process is not limited by the environment and space

 

Connection instructions for electrofusion composite pipe fittings:

The polyethylene pipes and welded fittings in the composite piping system of the gas station are joined by electrofusion. Because this method is less affected by climate. This method is suitable for on-site installation at gas stations. Nevertheless, the welding site should be kept dry and clean during the welding process. When soldering, the ambient temperature should be between -15ºC and +45ºC (+5ºF and +113ºF). Lower temperatures can only be performed under conditions of stable air temperature and increased protection measures. The principle of electrofusion welding is to heat the resistance wire under the inner surface of the welding pipe to a certain temperature (about 200ºC), and melt the PE (polyethylene) material inside the pipe fitting and outside the pipe. Due to the slow heat transfer of polyethylene, only the material near the resistance wire is melted. melt. Under the action of temperature and pressure, the polyethylene in the melting area expands, while the surrounding low-temperature polyethylene material prevents the melting area from expanding, so that the pipes are evenly and firmly welded together. When using the welding machine, the required power, heat and welding time are automatically calculated. Other welding machines cannot be used.
