Product Description

Acu-Tech sells Bead removers to remove the bead left by Butt Welding. Also known as De-beaders, these poly pipe installation tools remove the weld bead on the inside, or outside of the pipe. A different tool is used for removing the exterior HDPE pipe bead, and for removing the interior HDPE Pipe bead. Removing the bead will allow better flow through the pipeline and reduce friction.

Acu-Tech can supply External Debeaders, Internal Debeaders and Bead Gauges. Poly Bead Gaugegs are used to gauge the final bead width of a butt welded joint to ensure that the width is within the specified tolerance.

An External Debeading tool removes the outer bead that is formed on the exterior of the HDPE pipe when butt welding. External Debeaders dig into the bead, and use a ratchet motion to cut the bead smoothly off the outside of the pipe. Outside Debeaders are usually required for Casing or Sliplining, which is a method of repairing leaks or restoring structural stability to an existing pipeline. Sliplining involves installing a smaller carrier pipe into a larger host pipe, and the space between the two pipes is filled with grout or concrete, to stop movement. The smaller carrier pipe must have a smooth outside, and therefore the butt welding bead must be removed.

An Internal Debeader tool is used to remove the inner weld bead on the inside of a HDPE pipe. Unlike the outside debeader, the internal debeader has to reach up the length of pipe, sometimes up to 24m. The Internal Debeader overcomes this by using a drive handle and a cutter head to reach in and cut the weld bead from the HDPE Pipe. The inside debeader is usually used when the pipeline will carry slurries or other heavy fluids, where the internal bead will cause extra friction and sediment to build up. The standard internal de-beader suits pipe diameters from 90mm to 450mm, but larger internal debeaders are available for pipes up to 800mm. Contact our equipment team for more information!
