If you work in the energy industry, you may have heard of electric-resistance welded, or ERW, pipe. But what is ERW and how does it differ from seamless pipe? Read on for more information and a detailed video illustrating the manufacturing of ERW pipe at our facility in Lone Star, Texas.
Simply put, electric-resistance welded pipe is manufactured by welding the seam of an uncoiled roll of steel sheet together using electrical current and applied force; this differs from seamless pipe, which is produced by using a rotary piercing mill to transform a heated billet into a tube shell before further processing turns it into a finished pipe. Depending on the application, Lone Star Tubular Operations can produce welded pipe anywhere from 4-1/2" to 16" in outside diameter. Here is a video detailing how it all comes together:
Today, you can find our ERW pipe all over the United States, including many prominent hydrocarbon producing regions such as the Permian and Marcellus shale plays. We hope this has been informative.
