Standards for spiral steel pipe

Date:2024-07-26

Spiral steel pipes are extensively used across various industries due to their flexibility and cost-effectiveness, especially for large-diameter applications. Manufactured by spirally welding strips of steel to form a pipe with a spiral seam, these pipes are highly efficient and versatile. This article introduces the standards governing spiral steel pipes.
