Pipeline laying system

The process starts with digging the trench.

Next, a table or rack is set up above the trench to hold one or more sections of pipe. A roller system is required for the initial rack as well as the full length of pipe to be installed.

Next, a roller system is installed to straddle the trench so that the original pipe can be pulled off the table and will be at the same height and position as the next piece of pipe on the table. The two pieces of pipe can be welded together very easily.

Now these two sections of pipe can be pulled down the roller system just far enough so that the next piece of pipe can be positioned to align with the previous section of pipe. This can be repeated numerous times until the pipe sections have reached a designated stopping point.

Next, the welded pipe can be pulled down the roller system to make room for another system of pipes to meet the original system of pipes. This will only require one weld to connect these sections. This can be expanded to as many sections as conditions allow. When that direction is complete, the same process can be used going in the opposite direction.

When a hill is causing a problem by having to work on uneven ground, the answer is simple. Go to the top of the hill and set up a work station. It is easy to weld pipes together and pull them down hill with only one weld required. This works going down the other side of the hill.

For very long pipelines, work stations can be set up so numerous work crews can work at the same time.

When ready to install the pipe into the trench, a lift station can be installed on top of a roller station.

They have a hand winch and cable. The lift station lifts the pipe several inches and allows removal of the roller in the roller station. Now the pipe can be lowered into the trench with the winch.

This process eliminates stacking 4X4 lumber to position the pipe for welding. It also eliminates rental of lots of heavy equipment required to get the pipe into the trench.
