Large Diameter Steel Pipe Installation: Equipment Guide for 20–56 Inch Trenchless Projects
Installing steel pipeline from 20 to 56 inches requires specialized equipment that scales to the forces involved — often exceeding 1,000,000 lbs of push or pull force on long crossings. This guide covers the three key equipment categories: pipeline-class HDD rigs, pipe feeders, and mud systems. The UNI-PF250 pipe feeder contributes up to 400,000 lbs (200 short tons) of supplementary push force and supports HDD pullback, microtunneling, pipe jacking, and Direct Pipe® tunneling.
