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)
Flange part: carbon steel/stainless steel flange
3.2 Main manufacturing standards
ISO 4427 Polyethylene (PE) pipe system standard for water supply.
EN 12201 Pressure pipe system standard.

3.3 Choose the right Electrofusion Flange Adaptor
Choose the flange standard (PN10, PN16, ANSI150) according to the pipeline pressure level.
Confirm the compatibility of the pipeline material and the adapter.
Choose products that meet international standards to ensure long-term and stable use.
4. Comparison between Electrofusion Flange Adaptor and other connection methods
| Connection | Main Features | Applicable scenarios |
| Electrofusion Flange Adaptor | No additional sealing required, high welding strength and good corrosion resistance | Water supply, gas, industrial pipelines |
| Mechanical Fittings | The construction is quick, but the connection strength is slightly lower than that of electric fusion connection | Short-term projects, low-pressure pipeline networks |
| Butt Fusion | Requires specialized equipment, suitable for large diameter pipes | Long distance pipelines (municipal water supply, gas) |
| Direct welding of steel flange | Suitable for high temperature and high pressure systems, but the cost is relatively high | Chemical, mining, industrial pipelines |
4.1 Applicability analysis
Electrofusion Flange Adaptor is suitable for PE pipe systems with high requirements for sealing, especially in municipal water supply, gas transmission and other fields.
