Anti-corrosion steel pipe should choose spiral welded pipe or seamless pipe?

The selection of anti-corrosion steel pipes should be determined according to actual needs and specific environments. Both seamless pipes and spiral welded pipes have their own advantages and disadvantages.

Seamless steel pipes have higher strength and corrosion resistance, and because they have no welds, they can withstand higher pressures. In addition, due to its manufacturing process, the dimensional accuracy and finish of seamless steel pipes are also high. These characteristics make seamless steel pipes widely used in pipelines in petroleum, chemical, electric power and other industries.

However, spiral welded pipe also has its advantages in some aspects. First, spiral welded pipe is more efficient to produce, which can keep costs down for projects that require a lot of piping. Secondly, the weld seam of the spiral welded pipe is usually located inside the pipe, and its corrosion resistance may be better for some external corrosive environments. In addition, the compressive capacity of spiral steel pipe is relatively low, but in some applications with low pressure requirements, it can fully meet the needs.

To sum up, the choice of anti-corrosion steel pipe needs to be weighed according to the actual situation. If the requirements for strength, precision and finish are high, or it is used in a high-pressure environment, it is recommended to choose seamless steel pipes. If you need a large number of pipes, or use it in an environment where the external corrosion is not serious, you can choose a spiral steel pipe. No matter which type of anti-corrosion steel pipe is selected, it should be ensured that it meets relevant standards and safety requirements.
