Different Types of ERW Pipe

　　ERW pipe moves through the welding electrodes since it involves flattening of the steel and passing it through a hot furnace. The copper disk type is connected to a secondary assembly of revolving transformers whose main function is to attach on each side of the seam. It makes it possible for temperature being raised up to the welding point. When the tube is leaving the electrodes, the outer flash is removed during the process. The air hamer can wipe out the inside flash when the tube has been cooled. End product can be called ERW pipe, which is short for electric resistance welded pipe.

　　ERW pipe or electric resistance welded steel pipe is used for different purposes both in domestic and commercial sectors. The ERW pipe can be classified into general pipes, galvanized pipes, metric pipes, roller tubes, automobile tubes. The main function of ERW pipe is for transporting low pressure fluid. There are some methods to testing the bending and flattening capacities, like surface quality.The quality of metric pipe is similar to that of seamless pipes. The materials used to make metric pipes are general tropic low alloy-based steel, qualified carbon steel. You can use it for making structural components of engine drive shafts as well as transmission fluid.
