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 Read more

WELDED Steel Pipe Piles （ERW ,LASW, DSAW ,SSAW.） The two most common methods for steel pipe welding are straight seam or spiral seam welding. Welded steel pipes are typically used to transport fluid (water or oil) and natural gas. It is typically less expensive than seamless steel pipe. Both types of welding are applied after the pipe has been rolled, which involves shaping a sheet of steel into the end shape. Straight Seam: Straight seam welded steel pipes are manufactured by adding a welding parallel to the pipe seam. The process is fairly straightforward: Straight seam pipes are formed when a sheet of steel is bent and formed into a pipe shape, then welded longitudinally. Straight seam pipes can be submerged arc welded (SAW) or double-submerged arc welded (DSAW). Spiral Seam: Spiral seam welded pipes are manufactured when hot-rolled strip steel is formed into a pipe through spiral bending and welded along the then spiraled seam of the pipe. This results in the weld length being 30-100% longer than that of a straight seam welded pipe. This method is more commonly used on large diameter pipe. (Note: this method of welding may also be referred to as helical submerged arc Read more

Spiral weld pipe pile, otherwise known as SSAW Pipe pile, is a type of pipe piling product used in the construction of deep foundations. It is made from steel that has been formed into a spiral shape and welded together. It is used in a variety of applications, including bridge foundations, retaining walls, deep foundations for buildings, dams, and other large structures. Spiral weld pipe pile is a high-strength, low-alloy steel pipe made from a combination of rolled steel plates and helically wound steel strips. It is highly resistant to corrosion and has a high strength-to-weight ratio, making it an ideal choice for deep foundations and other high-load applications. The process of creating spiral weld pipe pile begins with hot-rolling a steel plate into a coil. This coil is then fed into a machine which shapes it into a spiral shape. This spiral is then cut into sections and welded together to form a single pipe pile. After the welding is complete, the pipe pile is then heat treated and tested to ensure it meets the desired specifications. Spiral weld pipe pile is a strong and reliable choice for any deep foundation or other high-load application. It is resistant to Read more

  Introduction Steel pipe piles have been used for many years as a foundation element in various construction projects. They are commonly used in the construction of bridges, buildings, and other structures that require a strong and stable foundation. The use of steel pipe piles has evolved over the years, with new technologies and techniques being developed to improve their performance and durability. One of the most significant advancements in the use of steel pipe piles is the transition from traditional steel pipe piles to spiral steel welded pipe piles. This paper will explore the technical transition of steel pipe piles to spiral steel welded pipe piles, including the benefits and challenges associated with this transition.

They are commonly used in deep foundation applications where the soil conditions are poor or where the structure being built is heavy. Steel pipe piles are typically driven into the ground using a pile driver, which forces the pile into the soil until it reaches a predetermined depth. Once the pile is in place, it provides Read more

Steel pipe piles and steel pipe sheet piles have found extensive applications in various construction projects, including ports/harbors, urban civil engineering, bridges, and more. These versatile piles are used in the construction of piers, seawalls, breakwaters, earth-retaining walls, cofferdams, and foundations for steel pipe sheet pile foundations. With the increasing size of structures, deeper water depths, and construction work on sites with deep soft ground, the usage of steel pipe piles and steel pipe sheet piles has expanded significantly.
