Description

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 through specific 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 high strength 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.

Usage: Used for low pressure liquid delivery, such as water, gas, and oil; construction and piling

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.

Applications

Steel pipe pile is a most recommend piling material for sea port constructions, yard buildings. It has been widely used in sea works or marine works, to create the tough foundations. Other than this, typical uses also as under buildings, bridges, and structural constructions. More details uses as below list:

Onshore and offshore constructions
Marine foundations / constructions
Tower building
Railway, highway construction
Dock yard construction
Sea works, marine works
Oil and gas filed fundations
Structural support in special buildings
and etcs.
