Circular duct chamfering machine PROTEM OHSB

for thick pieces

OD mount High Speed Pipe Bevelers for heavy wall thicknesses PROTEM OHSB For diameters 6 to 14 OD Facing Beveling : I, V, J, X shape or compounded bevels Counterboring Repeatable high quality surface High performance Perfectly suitable for manual or mechanised welding processes Perfect weld end preps on all materials: mild steel, stainless steel, exotic alloys such as incoloy, hastelloy, duplex, super duplex, copper, etc. The OHSB machine is hydraulically driven and is operated with a 55 kW HPU OHSB-OPTION : BORING BAR The particularity of the OHSB lies in its boring bar, which enables the ID of a pipe to be straight-turned over a depth of 0 to 200 mm. This option can be mounted either on the OHSB standard machine or on the OHSB-C Copying. This system element is located in the centre of the tool-plate. It holds one or two tool-blocks, sometimes more, on its end depending on its design. Boring bars can be delivered in very different configurations depending on machining require-ments. The tool-bars diameter may vary depending on the pipe ID, just like its length, which de-pends on the depth of bore required. - Possibilty to perform bevels up to 60 mm - Fast machining and easy mounting - Quick self align outside clamping system - Transportable machine. - Achieve perfect end surface - Deep conterboring - very powerful - high production rate - versatile - dependable - High precision - Safety chip guard For : - Spoolbases - Onshore - Offshore - Subsea - Barges - Prefabrication etc
