How to Correctly Determine the Thickness of Stainless Steel Welded Pipes

The thickness of a stainless steel welded pipe refers to its wall thickness. Normally, this label is affixed to the pipe itself, allowing customers to determine the thickness. However, what if the label has fallen off? The most professional method is to use calipers. But what if you don't have calipers or don't know how to use them? Here's a method to calculate the thickness of stainless steel welded pipes. We can calculate the thickness of a stainless steel welded pipe based on its outer diameter and weight using the following formula: Weight of round pipe: (Outer diameter - Thickness) * Thickness * 6 * 0.02491. For example, a stainless steel welded pipe with a cross-section of 38mm * 25mm, a thickness of 1.4mm, and a length of 6000mm can be calculated using the formula: (38 + 25) * 2 / (3.14 - 1.4) * 1.4 * 6 * 0.02491. This gives a theoretical weight of 8.10 kg/piece. When unsure of the stainless steel welded pipe's thickness, weighing it and then using the formula above will clearly indicate whether the purchased stainless steel welded pipe meets the thickness promised by the seller.
