Haikou spiral pipe classification and application

2023-10-17
723number



Spiral pipe features:straight seam welded pipe production process is simple, high production efficiency, low cost, rapid development. The strength of spiral welded pipe is generally higher than that of straight welded pipe, and welded pipe with larger diameter can be produced with narrower billet, and welded pipe with different diameter can also be produced with billet of the same width=100%. However, compared with the straight seam pipe of the same length, the weld length is increased by 30 to 100%, and the production speed is lower. Therefore, the smaller diameter welded pipe is mostly straight seam welding, and the large diameter welded pipe is mostly spiral welding.

So, where are the different spiral tubes used?

1. ordinary carbon steel wire bushing is a steel pipe used to protect wires in industrial and civil construction, installation machinery and equipment and other electrical installation projects.



2. The straight seam electric welded steel pipe is a steel pipe whose weld is longitudinally parallel to the steel pipe. Usually divided into metric welded steel pipe, welded thin wall, transformer cooling tubing and so on.



3. Spiral seam submerged arc welded steel pipe for pressurized fluid transportation is a spiral seam steel pipe made of hot rolled steel strip, usually warm spiral forming, and welded by double-sided submerged arc welding.



4. Welding steel pipe for low pressure fluid transportation is called general steel pipe, commonly known as black tube. It is a welded steel pipe used for conveying water, gas, air, oil and heating steam and other generally low pressure fluids and other purposes.



5. Galvanized welded steel pipe for low pressure fluid transportation is also known as galvanized electric welded steel pipe, commonly known as white pipe. It is a hot-dip galvanized welded steel pipe used for conveying water, gas, air, oil, heating steam, warm water and other general low pressure fluids or other purposes.
