- Material:
- Electrofusion Fittings: Made of polyethylene (PE) with embedded electric heating wires.
- PE Fittings: Made entirely of polyethylene (PE).
2. Connection Method:
- Electrofusion Fittings: Connected by heating the embedded wires with an electric current to fuse the pipe and fitting.
- PE Fittings: Connected by heat fusion or mechanical means (such as clamps or flanges).
3. Applications:
- Electrofusion Fittings: Used in high-reliability applications like gas, water, and sewage pipelines.
- PE Fittings: Used in water supply, drainage, gas, agricultural irrigation, and industrial pipelines.
4. Advantages:
- Electrofusion Fittings: High connection strength and reliability; suitable for harsh environments; faster installation.
- PE Fittings: Lower cost; simpler equipment and technical requirements; wide range of pipe and fitting options.
5. Disadvantages:
- Electrofusion Fittings: Requires specialized welding equipment; higher cost.
- PE Fittings: May have lower connection strength; potential leakage risk in high-pressure conditions with mechanical connections.
