Specialty Pipe Piling and Piles
Pipe piles are one of the most versatile pile found in the deep foundation industry. As such, there are several types of pipe piles that should be considered based on the application. These include:
Standard Steel Piles: Load bearing piles that support a large range of different pile types. Various attachments, including conical points, can be welded to the pile for more efficient driving throughspecific soil types
Micro Piles: Ideal for projects with minimal workspace and low headroom. In a mini caisson, the pile is filled with concrete to help reduce high underground pressures and reinforced with highstrength rebar
Helical piles or Screw Piles: These piles have a screw or helix welded to the end of the pile shaft. The pile is then“screwed”into the ground for deep foundation projects. This leads to an ease of installation, shorter project times and less soil displacement than other pile types.
The widely used forms of pile pipe: Usually in big diameters (heavy-duty steel pipe), dimensions from 16 inch up to 60 inch, manufactured using seamless, longitudinal welded (LSAW), or spiral welded(SSAW). Depends on the soil environments, pipe could be coated with zinc (galvanized), FBE or 3PE coated. In this way to provide moisture resistance and corrosion resistance.
