Piling Welded Steel Pipes: The Backbone of Strong Foundations

Piling welded steel pipes play a critical role in modern construction—especially where ground conditions demand high load-bearing capacity, long-term structural stability, and resistance to environmental forces. From high-rise buildings to bridges, ports, coastal facilities, and industrial foundations, these pipes form the invisible framework that keeps infrastructure standing strong.

As a supplier of engineered pipeline solutions across the Middle East, Africa, and Türkiye, Pipekom provides a wide range of piling-grade welded steel pipes—ERW, LSAW, SSAW/spiral welded—each designed to meet the unique technical requirements of different soil and project conditions.

🏗 What Are Piling Welded Steel Pipes?

Piling pipes are large-diameter welded steel pipes driven deep into the soil to support vertical loads or stabilize the ground. They can function as:

• Bearing piles

• Friction piles

• Combi-wall systems

• Microtunneling casings

• Marine jetty or quay wall piles

Welded piling pipes are preferred due to their strength, ease of fabrication, wide diameter range, and cost efficiency.

🔧 Types of Welded Steel Pipes Used in Piling

1️⃣ ERW – Electric Resistance Welded Pipes

• Produced from steel strip through high-frequency resistance welding.

• Available up to medium diameters (up to ~609 mm).

• High dimensional accuracy makes them suitable for many foundation works.

• Smooth internal surfaces and consistent wall thickness.

Best for: Building foundations, light industrial structures, and projects requiring high precision.

2️⃣ LSAW – Longitudinal Submerged Arc Welded Pipes

• Steel plate is formed and welded along a single longitudinal seam.

• Offers excellent strength, thickness capability, and straightness.

• Typically used for heavy load-bearing applications.

Best for: Bridges, port structures, offshore platforms, and large vertical loads.

3️⃣ SSAW / Spiral Welded Pipes

• Produced by helically welding steel plate or coil.

• Allows for very large diameters (up to 3 meters) with cost-effective manufacturing.

• Provides excellent flexibility in diameter-to-thickness ratios.

Best for: Marine piling, foundation piles, and deep soil stabilization projects.

⚙️ Technical Characteristics of Piling Steel Pipes

• FBE coating

• 3LPE / 3LPP

• Coal tar enamel

• Aluminum/zinc metallizing

• Concrete weight coating for marine piling

🌍 Applications of Piling Welded Steel Pipes

1️⃣ Building Foundations

Used to transmit loads of high-rise buildings into stable ground layers.

2️⃣ Marine & Port Infrastructure

Quay walls, jetty structures, dolphins, and offshore platforms all rely on piling pipes.

3️⃣ Bridge Construction

Ensures stability in varying soil conditions and riverbeds.

4️⃣ Industrial / Energy Projects

Tank farms, refineries, substations, compressor stations, and wind energy foundations.
