Pipe Facing Machine & Hydraulic Power Unit
The CRC-Evans Pipe Facing Machine (PFM) isused to machine precision bevels with extremeaccuracy for manual or automatic welding. Theyare typically used on cross-country pipelines,barges, and in stationary yards.
The PFM has two major parts; the clamping sectionand the machining section. The clamp section has twosets of hydraulically powered clamping shoes thatare designed to work equally and simultaneously. Themachine is secured to the pipe end by expanding theclamp shoes inside the pipe on PFMs ranging from8”-60” pipe. The machining section of the PFMconsists of a rotating faceplate with four or six toolholders each holding tunsten carbide cutting tips.
The tools can be set to machine a wide variety ofbevel designs and wall thicknesses. Each tool holdermay cut a different bevel angle simultaneously.
The PFM operation takes from 2 to 6 minutesdepending on pipe wall thickness and the experienceof the operator.
A CRC-Evans Hydraulic Power Unit (HPU) orequivalent is required to power the PFM. The CRC-Evans HPU is able to power the full range ofCRC-Evans PFMs. The PFM can also be directlyconnected to an excavator. Please ask CRC-Evansfor the appropriate flow chart.
Counterbore and Miter Pipe Facing Machines arealso available from CRC-Evans. Contact CRC-Evansfor sizes and counterbore depths.
