Pipe Debeaders

Debeader Internal

Internal debeaders supplied by Worldpoly are manufactured in Scandinavia to the highest standards. Although the internal beads are small and rounded causing little disturbance to flow, bead removal is sometimes required in order to comply with a clients' contract.
They have a capacity from 90 up to 630 mm / 3" to 24", and from SDR / DR 11 to 41. If beads thicker than SDR/DR 11 are to be removed, please contact sales@worldpoly.com for advice, and it is important to note that beads must be removed within the first 50% of the standard weld cooling time. This set consists of 6 pcs of alloy rods 2.15 meters each, one acting as a turn handle. 6 different pcs of centre rings are included to ensure that the first rod is aligned in the pipe. Alloy rods are delivered in a special carrying bag with a handle. 6 different debeader heads are available to suit inside diameters, and the internal debeader rod set can be extended up to 24 meters with the purchase of extra rods.
