Spiral steel pipes can be categorized in different ways based on various criteria. Here are several common methods of classification:

Categorically classified by pipe type: general welding spiral steel pipes, X80 large diameter high-strength spiral steel pipes, and alloy spiral steel pipes. Classified by diameter: large diameter spiral steel pipes and small diameter spiral steel pipes. Classified by wall thickness: thick-walled spiral steel pipes and thin-walled spiral steel pipes. Classified by specification: such as 219 spiral steel pipes, 273 spiral steel pipes, 325 spiral steel pipes, 529 spiral steel pipes, 630 spiral steel pipes, etc. Classified by material: Q235B spiral steel pipes, Q345B spiral steel pipes, X60 spiral steel pipes, etc. Spiral steel pipes of different types have various characteristics and applications. Choose the appropriate spiral steel pipe type based on the actual application scenario.
