“ERW welded steel pipe” is a straight seam resistance welded pipe, abbreviated as ERW. It is used to transport vapor and liquid objects such as oil and natural gas and can meet various requirements of high and low pressure. It currently plays a decisive role in the field of transportation pipes in the world.
1. Ordinary welded steel pipes refer to ordinary “submerged arc welded steel pipes”, which are represented by “SC” in electrical engineering. They can be used as water and gas pipes or as threading pipes. They are relatively thick.
2. The pipe conduit is also a wire conduit. It is relatively thin and is represented by “T”. It can only be used as a threading conduit.
3. ERW pipe is a “high-frequency resistance welded steel pipe”. It is different from the welding process of ordinary welded pipes. The weld seam is melted from the base material of the steel strip body, and its mechanical strength is better than that of ordinary welded pipes.
ERW stands for resistance welding. Resistance welding has the characteristics of high production efficiency, low cost, material saving, and easy automation. Therefore, it is an important welding process that is widely used in various industrial sectors such as industry, energy, electronics, automobiles, and light industry.
