END FACING AND BEVELING MACHINE (EFBM)

Pipe Production Systems

END FACING AND BEVELING MACHINE (EFBM)

PRD End Facing and Beveling Machines are suitable for pipe applications to meet any internationally known standards, including those of API and AWWA. End Facing and Beveling Machines can be used with pipes produced by the electric resistance welding (ERW) process as well as pipes produced by the submerged arc welding (SAW) process.

The range covered with PRD EFBM s are:

Pipe Diameter 20 (508 mm) to 120″ (3048 mm)
Pipe Length 4 meter to 20 meter
Material Thickness 5 mm to 25 mm
Material Grade Up to X 80
Cutting Angle 30 degrees with +5, -0 tolerances

Main EFBM components are:

“Pipe Clamps
“Spindle and Cutting Head Assembly
“Positioning System
“Pipe Rotating Unit
“Drive and Hydraulic System
“Controls and Tooling

PIPE CLAMPS

Two pipe clamps, top and bottom, are made of machined steel in sections. The top clamp is fixed while the bottom clamp can be vertically adjusted by means of hydraulically driven cylinders to fix the pipe in position. Bolt-on Inserts are fixed onto the clamps. Different bolt-on inserts are needed for each diameter of pipe.

SPINDLE AND CUTTING ASSEMBLY

The spindle is made of forged steel. A faceplate holding the cutter assembly with cutter heads is mounted onto the spindle by a flanged connection. The cutter assembly is mounted on the faceplate in such a way that any positioning of the cutter heads along the faceplate axis is possible. Cutter heads are complete with insert-type cutting tool holders. The complete assembly is mounted on a large anti-friction tapered-roll bearing, which is sealed and lubricated by a gear pump.

POSITIONING SYSTEM

Positioning of the faceplate and cutter heads feed is accomplished by means of servomotors and gear reducers. All high-speed in and out movements of the faceplate and fine and course feed of the cutter heads are controlled through the operator panel provided by the beveling head which allows continuous inspection by the operator during beveling.

DRIVE and HYDRAULIC SYSTEM

The faceplate and cutter head assembly is furnished with a variable speed, high torque, DC drive. Each beveling head has an independent drive and hydraulic system complete with hydraulic pumps, motors, reservoir, filters, valves and controls.

CONTROLS and TOOLING

All beveling head and pipe positioning controls are provided through an individual operator control panel located by the beveling head itself. The PLC system allows automatic operation for pipes having same characteristics.

Cutter head assemblies are designed and positioned on the face plate to bevel the pipe ends and to machine a flat surface perpendicular to the horizontal axis of the pipe. This is accomplished by one facing tool (fixture) which is stationary and one bevel tool (fixture) which is floating with respect to the cam follower provided.
