- What is black pipe?
Black pipe is a kind of steel pipe with black surface, also called black welded pipe or welded black pipe. It is usually made of ordinary carbon structural steel, low alloy structural steel or alloy structural steel through welding, processing and other processes.
Second, the characteristics of black pipe
Black pipe has the following characteristics:
- black surface, compared with other steel pipe has a better aesthetic;
- high strength, strong pressure resistance, can withstand greater pressure;
- excellent corrosion resistance and better ability to withstand chemical action;
- good mechanical properties, tensile, compressive, bending ability is stronger.
Third, the application field of black pipe
Black pipe is widely used in construction, engineering, petrochemical, chemical, metallurgy, shipping, electric power, environmental protection and other fields, and its application covers steel components in various fields. For example, columns, beams, supporting structures of steel plate overlap in construction; pipelines for conveying liquids and gases in petrochemical and chemical industries, as well as for making equipment such as steam boilers, pressure vessels, coolers, heat exchangers and so on.
The difference between black pipe and other steel pipe
The difference between black pipe and other steel pipe mainly lies in the surface treatment and manufacturing process. The surface of black pipe is black, while the surface of other steel pipes can have different treatments such as galvanized, sprayed, etc.; black pipe is usually made through the welding process, while other steel pipes may use different manufacturing processes.
- Conclusion
Overall, as a widely used steel component, black pipe has many features and advantages. It is hoped that through the introduction of this paper, readers can have a better understanding of the relevant knowledge of the black pipe, which can provide reference for the application in practical work and life.
