Common OD range of spiral steel pipes is between 219mm and 3820mm, with wall thickness ranging from 2mm to 30mm.

Generally, the outer diameter of spiral steel pipes depends on the specifications of the production equipment and the thickness of the pipe material, with common sizes including 219mm, 325mm, 406mm, 508mm, 610mm, 711mm, etc. Custom sizes are also available upon customer request. The wall thickness of spiral steel pipes is a crucial parameter affecting their strength and pressure resistance, with common thicknesses ranging from 6mm to 14mm. Custom thicknesses can also be provided as per customer requirements.

Note that overly thin wall thickness can affect the pipeline's strength and corrosion resistance, while excessive thickness will increase production costs and transportation fees. Additionally, the material for spiral steel pipes is typically large-diameter low-alloy structural steel or carbon structural steel. In some special cases, stainless steel or high-performance alloys may be required. The specific choice should be made by the customer based on their application needs.

In summary, the outer diameter and wall thickness of spiral steel pipes may vary due to different production equipment, applications, and customer requirements, necessitating a specific analysis based on the actual circumstances.
