Similar to H-Piles, piling pipe 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.
Piling pipe are also used in conjunction with sheet piles to add lateral stiffness and bending resistance where loads exceed the capacity of sheet piles alone.
Threeway steel provides ERW, DSAW and Spiral weld pipe pile in a wide range of sizes and lengths to meet your requirements. In addition, Threeway steel provides value added services such as coating and welding to facilitate complete pipe pile solutions. The piling pipe shown on this page was coated and welded into 160’ lengths.
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.
