  • Collaring Technology | Pipe Tee forming - T-DRILL | Tube ...

    Pipe branching – i.e. connecting a branch pipe to a run pipe – using T-DRILL method is also called collaring. The joint can be completed by brazing (= lap joint) or by welding (butt joint). For the lap joint process, a round hole is drilled in the pipe wall using a collaring head. After the tube wall is penetrated, two forming pins are extended from the drill bit.
