Two ends.
One pipe.

Butt fusion melts two HDPE pipe ends together into a strong, leak-proof joint. We supply the hydraulic butt fusion and electrofusion machines that do it.

  1. 1 Face and align

    Both pipe ends are trimmed square and clamped in line.

  2. 2 Heat

    A heater plate softens the ends until a bead of melt forms.

  3. 3 Change over

    The plate comes out quickly, before the ends cool.

  4. 4 Fuse and cool

    The ends meet under pressure and cool into one continuous joint.

Why HDPE

It can be bent and curved, so you need fewer fittings. It fuses into leak-proof joints. And it stands up to corrosion and harsh chemicals.

  • Leak-free joints

    Fusion welding makes strong, reliable, leak-proof connections.

  • Corrosion resistant

    Handles harsh chemical environments with long-lasting performance.

  • Flexible

    Can be bent and curved, minimising the number of fittings needed.

  • Lightweight

    Cheaper to transport and easier to install than traditional metal pipe.

  • Smooth bore

    Low-friction interior improves flow and reduces pressure losses.

  • Low maintenance

    Once installed, minimal upkeep keeps lifetime costs down.
