8" Transmission Pipe Pile

The MPS 8" Transmission Pipe Pile is a helical pile designed to resist large axial, lateral and moments loading. Transmission Pipe Piles are used in foundations of substations and lattice towers.


The MPS F-86 pile offers:

  • Our square on square coupler technology to optimize pile performance during installation and usage. 
  • Limiting rip out failure due to installation torque as seen in pipe sleeve connections. 
  • An economic deep foundation solution for poor subgrade conditions lacking adequate support due to low consistency soils such as swamps or beach environments.
  • A high capacity load resistance in compression up to 250 kips (1,112 kN), in tension up to 150 kips (667 kN) and in lateral up to 15 kips (67 kN).
  • Load resistance is based on pipe wall thickness and soil conditions.     
  • Features a double cut nose for ease of installation as well as an internal coupling system with threaded bolt holes to ensure a snug fit between pipe segments.

Leads are available with helices ranging from 14-24” (355-610mm) in 2” (50mm) increments on 5, 7, and 10 foot sections (1.5, 2.1, 3m).

Extensions are available with or without helices in 5, 7, and 10 foot sections.
