Saudi Arabia - 2004
Equipment used - 15 ton capacity OT Rollers with Accu-Roll System
This pipeline is being laid to transport water which is injected into oil wells to maintain pressures.
Hilman Rollers' 15 ton capacity OT Rollers with Accu-Roll System replace a cam follower arrangement in a Positive Seal Coupling Joining Unit machine. In this operation, the Pipe Coupler Machines are suspended in the air by cranes so they cantwist and turn to adjust to the pipe.
The 15-OT with Accu-Roll are guides for 16" travel block pistons and the Rollers move 2 feet in one direction and then back again while bearing a constant load of 10 tons.
The Hilman Rollers help make the system much more stable under load. They have the ability to withstand vertical loads upward or downward and horizontally.
