Product Details

ERW black steel pipe refers to the steel pipe produced by the high-frequency resistance welding process. The welding seam is formed by melting the base material of the steel strip itself, which has better mechanical strength than ordinary welded pipe. ERW black steel pipes are widely used to transport vapor and liquid objects such as oil and natural gas and can meet various requirements of high and low pressure. ERW black steel pipe occupies a pivotal position in the field of transportation pipes in the world. ERW black steel pipe has the characteristics of high production efficiency, low cost, material saving, and easy automation, which make it widely used in various industrial sectors such as energy, electronics, automobiles, and light industry, and is an important welding process.
