An Article on Micro Tunneling for Pipeline Installation tunnelling steel pipe systems

Micro Tunneling (M/T) is a process that uses a remotely controlled Micro Tunnel Boring Machine (MTBM) combined with the pipe jacking technique to directly install product pipelines underground in a single pass. This process avoids the need to have long stretches of an open trench for pipe laying, which causes extreme disruption to the community.Aggregate Conveyor Tunnel - True North Steel10 Diameter 10 Ga 3×1 Corrugated Steel Pipe is used as a conveyor tunnel to move aggregate from processing pile.
