ERW BLACK
STEEL
PIPE |
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. |
We can do |
1. All the pipes are high-frequency welded. |
2. Both inner and outer welded stabs can be removed. |
3. Special design available according to requirements. |
4. Pipe can be necked down and punched holes. |
5. Supplying BV or SGS Inspection if the client needs it. |
