Piling Pipe

To manufacture high-quality steel pipe piling, we use the coils or plates – between 5mm and 50mm thickness with the Submerged Arc Welding technology , comply to SSAW and LSAW type with spiral welding seam and straight welding seam respectively.

Our pipe pilings are typically 12 to 36 inches in diameter but can be custom made to your exact size and specification. These pilings are effective load bearers and are perfect for construction with heavy loads or deep foundation structures.

Description

Steel pipe piles are cylindrical steel foundation members used to transfer structural loads to deeper, more competent soil or rock layers. They can also serve as permanent casings for cast-in-place concrete piles. Depending on the project design, steel pipe piles can be manufactured with longitudinal or helical weld seams, with diameter, wall thickness, length, and material grade selected to meet the required structural performance.

Technical Specifications:

Outer Diameter (OD): 219.1 mm to 3048 mm (8" to 120")
Wall Thickness (WT): 5.0 mm to 50.0 mm
Length: Single lengths up to 18–24 meters, custom fabrication, and field-spliced lengths available.

Welding Technology:

SSAW (Spiral Submerged Arc Welded Pipe)
LSAW (Longitudinal Submerged Arc Welded Pipe)

ERW (Electric Resistance Welded Pipe)

Applications of steel pipe piles

Steel pipe piles are used in foundation and infrastructure projects where the required load capacity or ground conditions cannot be adequately addressed by shallow foundations alone.

Typical applications include:

Building and industrial foundations
Bridge piers and highway infrastructure
Marine piles for ports, docks, and quay structures
Foundation support for heavy equipment and structures
Pile foundations in deep or variable soil conditions
Steel casings for cast-in-place concrete piles

Value-Added Services & Customization:

Beveling & End Preparation (30°, 37.5° for field welding)

Welding Accessories: Drive shoes, backing rings, conical points, and pile caps.

Protective Coatings: 3PE/3PP, Single/Double layer FBE, Coal Tar Epoxy, and Marine Anti-corrosion Coatings.
