ERW piling pipe | ERW Steel Pipe Pile | Welded ERW for Structure

ERW (Electric Resistance Welded) pipe piling is a type of steel pipe that is commonly used in construction and foundation applications, such as in the building of bridges, wharves, and other structures. ERW pipe piling is created by using a process in which a flat steel strip is rolled into a tube shape, and then the edges are heated and welded together using an electric current.

ERW pipe piling has a number of advantages over other types of piling, including:

Cost-effective: ERW pipe piling is generally less expensive than other types of piling, such as seamless pipe piling.

High strength: ERW pipe piling is highly resistant to bending, making it a strong and durable option for foundation applications.

Customizable: ERW pipe piling can be manufactured to meet specific size and length requirements, making it highly customizable and adaptable to different project needs.ERW Pipe Piling is available in a range of sizes and thicknesses, and can be produced in lengths of up to 100 feet or more. It is typically made from carbon steel or alloy steel, and can be coated with a layer of protective material to help prevent corrosion and extend the lifespan of the pipe.

Versatile: ERW pipe piling can be used in a variety of soil conditions, including hard rock, clay, and soft soil.

ERW Pipe Piling is characterized by its high strength and durability, making it suitable for use in heavy-duty applications. It is also relatively inexpensive compared to other types of steel pipe, making it a popular choice for projects with tight budgets. It’s important to consult with a structural engineer or construction professional to determine the best type of piling for your specific project needs.



Why is erw steel pipe used for piling pipe

Depending on the characteristics of the pipe in question, such as its diameter, wall thickness and type of weld used, a steel pipe pile foundation is capable of bearing millions of pounds weight.

Wood piles can be subject to a host of erosion and rotting issues in water, limiting their life span and usability. Driving concrete piles can cause significant vibration and displacement issues, and depending on the environment may not be a viable option.

In contrast,ERW steel pipe pilings can be coated and treated to withstand corrosion, and driving steel piles underwater is easily achieved with the right equipment.ERR Steel pipe can be tailored to fit your precise loading requirements, meaning they can be cheaper to source and install.

They’re relatively lightweight relative to concrete pilings, making them cheaper to transport. And testing and inspection of steel pipe pilings prior to installation is very straightforward.

Electric Resistance Welding (ERW) Process

In the Electric Resistance Welding (ERW) process, a flat sheet of steel is cold-formed into a cylindrical shape to manufacture pipe. Then current is applied to either edge of the steel cylinder, and the steel is heated to the point that the edges forcibly form a bond without welding filler material.
This type of welded pipes are majorly used for pipe pile and piling pipe.
