Why Are Anti-Corrosion Steel Pipes Mostly Spiral Steel Pipes?

In recent years, anti-corrosion steel pipes have begun to be widely used in the construction of water, natural gas and thermal pipelines. Anti-corrosion steel pipes usually use spiral steel pipes. What is the reason? Let’s explore it in this article.

1. The diameter of spiral steel pipes is usually relatively large, which meets the current requirements of water supply pipelines, natural gas pipelines and heating pipelines.

2. Compared with ordinary open section steel sections, round tubes and square and rectangular tube sections have the characteristics of smooth surface, no dead corners, and small external area. Spiral steel pipes are conducive to saving anti-corrosion and fire-retardant coatings, and are easy to remove dust.

A. During the forming process, the steel plate is deformed evenly, the residual stress is small, and the surface is not scratched. The processed spiral steel pipe has greater flexibility in the size and size range of diameter and wall thickness, especially when producing high-grade thick-walled pipes, especially small and medium-diameter thick-walled pipes. There are many specifications for spiral steel pipes.

b. The use of advanced double-sided submerged arc welding technology can achieve excellent position welding, which is not prone to defects such as misalignment, welding deflection, and incomplete welding, and the welding quality is easy to control.

C. 100% quality inspection of steel pipes puts the entire steel pipe production process under effective inspection and monitoring, effectively ensuring product quality.

d. All equipment in the entire production line has the function of networking with the computer data collection system, real-time data transmission, and the central control room controls the technical parameters in the production process.

2. The wind resistance coefficient of the steel pipe section is small, which has significant advantages when exposed to fluids (such as wind and water flow).

3. The internal space of the steel pipe structure is available. For example, filling concrete steel pipes can not only increase the load-bearing capacity of the component, but also extend the fire resistance limit of the component; water is injected into the pipe and the internal water circulation can be used for fire prevention.

4. Can transport liquids in pipelines. At present, oil pipeline bridges and stormwater drainage pipelines have been developed based on this feature.

5. Prestressed cables can also be placed inside the pipe to apply prestress to the pipe body.

Generally speaking, the reason why anti-corrosion steel pipes are mostly spiral steel pipes is based on its own characteristics. If you want to know more, please contact: sales@union-steels.com
