How Electrofusion Fittings Work?
Electrofusion fittings contain built-in electrical heating coils. When connected to an electrofusion control unit (ECU) and energized, the coils heat the surrounding material and the pipe surface. This controlled heating softens and melts the material, creating a strong molecular bond between pipe and fitting. Fusion indicators on the fitting confirm when the process is complete, ensuring a leak-free, pressure-resistant joint.
Applications & Use Cases
Water Supply & Plumbing Systems — leak-resistant joints in potable water installations
Gas Distribution — reliable fusion joints for low / medium pressure gas lines
Irrigation & Agricultural Piping
Industrial Process Piping — chemical, food, or wastewater lines
Mining / Infrastructure Projects — robust and field-friendly fittings
FAQ
Q1: What is an electrofusion fitting?
A: It’s a specialized fitting with embedded heating elements that fuse to PE pipes when energized, creating a permanent, leak-proof joint.
Q2: What pipe types are compatible?
A: These fittings are designed for
HDPE / PE100 pipe systems; ensure pipe SDR and wall thickness match fitting specifications.
Q3: How to choose between coupling and saddle fittings?
A: Use
couplers for inline connections;
saddles for tapping laterals or branch lines without cutting the main pipe.
Q4: What is the rated pressure for electrofusion fittings?
A: It depends on the fitting model, commonly PN10 / PN16 / PN20. Always refer to manufacturer data sheet.
Q5: How do electrofusion fittings work?
A: Electrofusion fittings use embedded heating wires to fuse with the pipe surface. When electric current passes through, the heat melts the pipe and fitting interface, forming a permanent, leak-proof joint.
Q6: What is the difference between electrofusion and butt fusion?
A: In electrofusion, the fitting itself provides the heat via coils, making it ideal for tight spaces or repairs. Butt fusion requires heating the pipe ends directly with a heating plate before joining.
Q7: What materials are electrofusion fittings made of?
A: Most electrofusion fittings are made from
PE100 or HDPE material, designed to be compatible with polyethylene pipe systems.
Q8: Where are electrofusion fittings used?
A: They are widely used in
gas distribution, water supply, sewage systems, industrial pipelines, and mining projects where strong, leak-free joints are essential.
Q9: What pressure can electrofusion fittings withstand?
A: Depending on size and design, electrofusion fittings can typically handle
PN10, PN16, or PN20 pressure ratings. Always check manufacturer specifications.
Q10: Do electrofusion fittings require special equipment?
A: Yes. Installation requires an
electrofusion control unit (ECU), pipe scraping tools, and clamps to ensure alignment and proper fusion.
Q11: How long does the electrofusion process take?
A: Fusion times vary depending on fitting size and pipe diameter but typically range from
a few seconds to several minutes. Cooling time is also required before pressurization.
Q12: Are electrofusion fittings reusable?
A: No. Once fused, the fitting cannot be reused. A new fitting must be installed for each joint.
Q13: Can electrofusion fittings be used underground?
A: Yes, they are commonly used in buried gas and water pipelines because of their durability and strong sealing performance.
Q14: How reliable are electrofusion fittings?
A: When installed correctly, electrofusion fittings provide
long-lasting, leak-free joints with lifespans often exceeding
50 years in standard service conditions.
