Compared with traditional welded pipes, S235 J0 spiral steel pipe has the following significant features:

A. During the forming process, the steel plate deforms evenly and has minimal residual stress. Not only does this extend the life of the pipe, it also ensures that the pipe surface is smooth and free of scratches or defects.

b. Our advanced double-sided submerged arc welding process enables precise welding in the best position. This significantly reduces the occurrence of defects such as misaligned edges, welding deviations, and incomplete welding. As a result, our pipes have excellent welding quality, are easy to control and ensure excellent performance.

C. Quality is our top priority. Therefore, we perform thorough 100% quality inspection on every steel pipe we produce. This comprehensive inspection guarantees that our pipes meet the highest industry standards, giving you peace of mind throughout the production and use process.

a. The deoxidation method is designated as follows: FF: Fully killed steel containing nitrogen binding elements in amounts sufficient to bind available nitrogen (e.g. min. 0,020 % total Al or 0,015 % soluble Al). b. The maximum value for nitrogen does not apply if the chemical composition shows a minimum total Al content of 0,020 % with a minimum Al/N ratio of 2:1, or if sufficient other N-binding elements are present. The N-binding elements shall be recorded in the Inspection Document.
