    ERW, DSAW And Spiralweld

    Similar to H-Piles, Pipe Piles are also designed to transfer structural loads through the foundation to soils below. Where H-Piles are typically classified as point bearing, Pipe Piles are most efficient as friction piles. Pipe Piles have substantial surface area that interacts with the surrounding soil to provide great frictional load resistance.

    Pipe Piles are also used in conjunction with sheet piles to add lateral stiffness and bending resistance where loads exceed the capacity of sheet piles alone.

    L.B. Foster provides ERW, DSAW and Spiralweld pipe pile in a wide range of sizes and lengths to meet your requirements. In addition, L.B. Foster provides value added services such as coating and welding to facilitate complete pipe pile solutions. The piling  shown on this page was coated and welded into 160’ lengths.

    Pipe Pile Technical Data


    Electric Resistance Weld pipe  is normally produced in sizes from 2 3/8 inch OD thru 24 inch OD.

    ERW is produced from individual sheets or continuously from rolls of skelp. There are two important differences in the production of ERW pipe as versus CW pipe. ERW pipe is cold formed into a cylindrical shape rather than hot formed. An electric current rather than a flame is used to heat the edges of the strip for the fusion weld. Revolving copper discs serve as electrodes and raise the temperature to about 2600°F for effective welding. As in CW pipe, no extraneous metal is added; in fact, due to the extreme pressure of the rolls, steel is extruded on both the inside  and outside of the pipe at the point of the weld. This is called flash and is  removed on the O.D. by stationary cutters while still white-hot for A252 grades, and both the I.D. and O.D. for other grades. As in CW production, ERW  pipe is subject to numerous finishing operations. ERW pipe is primarily used as API Line pipe for the transmission of gas and oil. It is also used for the transmission of water, under AWWA specifications, as piling and slurry pipe and in mechanical applications.

    L.B. Foster provides ERW piling  in sizes ranging from 8 5/8" OD to 24" OD with the wall thickness  range of 0.250" to 0.625". L.B. Foster is proud to be the exclusive  distributor of TRU 12™ ERW pipe piling. TRU 12™ pipe piling is produced with an  actual 12" OD diameter versus the common 12.75" OD providing cost  savings in weight per foot of pile, shipping costs and construction fill.

    Double Submerged Arc  Weld Pipe

    Double submerged arc welded  pipe (DSAW) derives its name from the welding process wherein the welding arc is submerged in flux while the welding takes place. Both inside and outside welds are required and are usually accomplished in separate processes, hence  the word "double." These separate welds consume a portion of the other, resulting in a single high quality weld nugget.

    DSAW pipe is produced in sizes from 18" through 66" OD and wall  thicknesses from .250" through 1.5".

    Two different processes are used to manufacture DSAW pipe; the pyramid rolls  method, and the U-0-E method. The difference in the processes is found only in  the method of forming the cylinder. In the pyramid rolls process the cylinder  is formed between 3 rolls arranged in a pyramidal fashion. As the name implies, the U-0-E method uses a "U" press, and "O" press for  forming. Other parts of the process such as finishing and inspection are  similar. Both processes use flat steel plate as the raw material.

    DSAW pipe may or may not be cold expanded. Cold expansion is a process where  the pipe is expanded (up to 1.5%) to obtain its final OD dimension. In the  process, a gain of yield strength results. Expansion is most often utilized in  a U-O-E mill due to the need to recover the yield strength lost during forming  in the "O" press.

    DSAW pipe is normally produced in double random lengths with square ends or beveled for welding.

    DSAW pipe is used in high-pressure gas and oil transmission lines (both onshore and offshore), structural members and pipe piles.

    Spiral Weld Pipe

    Spiral Weld Pipe, as the name  implies, is a steel pipe that has a seam running its entire length in a spiral form.

    In the past, due to the method of manufacture, Spiral Welded pipe was relegated to low pressure and structural applications. With the development of the Submerged Arc Welding process, the production of large hot rolled coils of sufficient width and the development of dependable non-destructive testing methods, it is now possible to produce Spiral Weld pipe for high-pressure  service.

    Present Spiral Weld mills consist of a de-coiling device (in the case of strip  base material) or a plate preparation table (where the base material is in  plate form) a strip connecting welder, straightening rollers, edge preparation tools (shearing and trimming), prebending devices, a three roller bending and cage forming system, an internal welder, an external welder (both Submerged Arc), ultrasonic testing apparatus and cutting devices.

    The material passes through all these production stages continuously. The angle between the flat strip being fed into the machine and the finished pipe leaving the machine controls the pipe diameter in ratio to strip width and the angle of the weld in the pipe.

    Because of the method of manufacture, a wide variety of diameters can be  produced. The diameter tolerance is small, particularly with regard to ovality; and the pipe, due to its axial symmetry, has an inherent straightness. The length range is infinite and is controlled only by the economics of transportation.

    Spiral Weld Pipe is used for dredging, slurry, water and other pipelines, as well as piling and structural applications.

    Spiral Weld Pipe is produced in accordance with the dimensional and tolerance requirements of various ASTM, AWWA, and API Specifications.
