What Does Pull Pressure Mean?

Pull pressure is the physical force used or required to pull pipes into position. During installation, pipes may need to be pushed, pulled or rotated depending on the design and methods used. Pull pressure is one of the forces used and measured in trenchless construction operations.


Trenchlesspedia Explains Pull Pressure

Pipe installation, in simple terms, is the movement of pipe from one place to another. In conventional trenching, pipe is laid into the ground in an open trench. But trenchless construction requires a different type of movement. A pipe could be pushed forward using a method known as pipe ramming, or it can be attached to a machine that pulls it back through the borehole.

The pullback of a pipe is used in horizontal directional drilling once the pilot hole has been drilled and reamed. Pull pressure is the amount of force used to pull the pipe back through the borehole. The pressure used should not exceed the predetermined maximum safe pull pressure. Pull pressure can be measured with sophisticated instruments.
