Counterboring Pipe

Counterboring is machining the inside (ID) of the pipe, after the initial surface weld prep and prior to welding, to create transition, tapers or smoothing. All Wachs split frames, equipped with counterboring accessories, are ideal for counterboring, with 3 inch and 6 inch pivot counterbore modules available depending upon the depth required, for use with the DynaPrep MDSF. Wachs EP 424 and SDB end prep machines are capable of limited counterboring as well.
