The Large Diameter Split Frame (LDSF) is designed for cold cutting, bevelling, facing and counterboring on large diameter pipes, vessels and flanges. Each machine covers a 15in (381mm) diameter range and will simultaneously cut and bevel most wall thicknesses and materials. Spring loaded O.D. tracking slides allow the tooling to maintain continuous contact even on irregularly shaped pipe. A new patent pending Counterboring and Reverse Bevel module (CRBM) counterbores in vertical orientation, and reverse bevels in angled orientation.
