Electrofusion Flange Adaptor

1. What is Electrofusion Flange Adaptor?

1.1 Definition and Function

Electrofusion Flange Adaptor is a pipe fitting used to connect polyethylene (PE) pipes and metal flange systems. It uses electrofusion welding to form a high-strength integrated connection with PE pipes, and connects with valves, pumps, metal pipes and other equipment through flanges.

1.2 Main Features and Advantages

High-strength connection: electrofusion welding ensures firmness and no leakage.

Strong corrosion resistance: Suitable for water supply, gas, chemical and other industries.

Wide adaptability: Can be matched with flanges of different standards (PN10, PN16, ANSI 150, etc.).

Easy installation: Reduce additional sealing treatment and improve construction efficiency.

1.3 Main application areas

Municipal water supply and sewage treatment

Gas transmission pipeline

Agricultural irrigation and industrial pipeline system

Petrochemical and mining applications

2. Installation and use guide of Electrofusion Flange Adaptor

2.1 Preparation before construction

Make sure the adapter matches the PE pipe.

Clean the outer wall of the pipe to remove moisture, oil and dust.

Use a scraper to remove the oxide layer on the surface of the pipe to improve the welding quality.

2.2 Installation steps

1. Mark the welding position: measure and mark the welding area of the pipe.

2. Pipe pretreatment: use a scraper to remove the oxide layer.

3. Assemble the flange adapter: insert the Electrofusion Flange Adaptor into the pipe.

4. Electrofusion welding: connect the electrofusion welding machine and perform welding according to the recommended parameters.

5. Cooling and fixing: keep it still until it is completely cooled (10-20 minutes).

6. Connect the flange system: tighten the flange evenly with bolts.

2.3 Installation precautions

Avoid humid environment to prevent affecting the quality of welding.

Adjust welding parameters according to the manufacturer's technical requirements.

Perform welding when the pipeline is under no pressure to ensure the quality of the connection.

3. Materials and manufacturing standards of Electrofusion Flange Adaptor

3.1 Common materials

Main material: PE100 (high-density polyethylene)
