AC welding is divided into low-frequency welding, intermediate-frequency welding, super intermediate-frequency welding, and high-frequency welding according to the different frequencies. High-frequency welding is mainly used for the production of thin-walled steel pipes or ordinary thick-walled steel pipes. High-frequency welding is divided into contact welding and induction welding. DC welding is generally used for small-diameter steel pipes. Generally speaking, the high-frequency welded pipe is included in the ERW welded pipe, which is a kind of ERW welded pipe produced by the high-frequency welding process. ERW longitudinal welded pipe is a steel pipe with advanced performance, leading quality, and a relatively economical product in the field of oil and gas storage and transportation.\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:heading -->\r\n<h2>What is the Raw material required for manufacturing Seamless &amp; ERW Stainless steel Pipes?<\/h2>\r\n<!-- \/wp:heading -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nSeamless Steel Pipe is made from a solid round steel \u2018billet\u2019 which is heated and pushed or pulled over a form until the steel is shaped into a hollow tube.
