What is Pipe Fusion Welding?
Pipe fusion welding is an advanced process that creates continuous, leak-proof joints between PE pipes. Unlike traditional mechanical fittings or adhesives, fusion welding uses heat and pressure to fuse the pipe materials together at a molecular level, resulting in a homogeneous, seamless connection.
Electrofusion Welding
Electrofusion welding, on the other hand, utilises specialised fittings embedded with a heating coil. The process involves:
- Preparation: The pipes and fittings are cleaned and scraped to ensure proper fusion
- Alignment: The fitting is aligned and clamped onto the pipe ends.
- Fusion: An electrical current is passed through the heating coil, melting the plastic in both the fitting and the pipe surfaces.
- Cooling: Once fully fused, the joint is allowed to cool, creating a sturdy, leak-proof connection.
Our electrofusion welding capabilities extend from 20mm up to 800mm pipe diameters, catering to a wide array of applications.
Butt Fusion Welding
Butt fusion welding is a technique suited for joining PE pipes end-to-end. The process involves:
- Facing: The pipe ends are precisely trimmed to create parallel, clean surfaces.
- Aligning: The pipe ends are carefully aligned and clamped together.
- Heating: A heated plate is inserted between the pipes, melting the surfaces.
- Joining: The heated plate is removed, and the molten pipe ends are brought together under controlled pressure, fusing them into a single, continuous length.
Our team is equipped to handle butt fusion welding for pipe diameters ranging from 63mm up to 900mm, providing solutions for projects of all scales.
What are the Benefits of Fusion Welding?
Both butt fusion and electrofusion welding offer numerous advantages over traditional pipe joining methods:
Leak-proof Joints
Fusion welding creates homogeneous, monolithic connections, virtually eliminating the risk of leaks..
Strength and Durability
The fused joints are as strong, if not stronger, than the pipes themselves, ensuring long-lasting performance.
Chemical Resistance
PE pipes fused through these methods remain highly resistant to corrosion and chemical attacks.
Versatility
Fusion welding is compatible with various thermoplastic materials, including high-density polyethylene (HDPE), medium-density polyethylene (MDPE), and polypropylene.
No Additional Adhesives or Solvents
The fusion welding process does not require any additional bonding agents, reducing potential environmental impacts and long-term maintenance issues.
By following this rigorous process, we ensure that the water sampling data you receive is accurate, reliable, and compliant with industry standards.
