How to correctly judge the thickness of stainless steel welded pipe

How to correctly judge the thickness of stainless steel welded pipe The thickness of stainless steel welded pipe refers to the wall thickness of the pipe. In general, the wall thickness of stainless steel welded pipe will be affixed to the pipe body. Customers can know the thickness through the label on the pipe body. Fire-fighting steel-plastic composite pipe, but if the label on the steel pipe body falls off, how to judge its thickness? The more professional method is to use a caliper to measure, but what should I do if I don’t have a caliper or I don’t know how to use it at all? Torch here explains a method to calculate the thickness of stainless steel welded pipes. We can use the following formula to calculate the thickness of the tube according to the outer diameter and weight of the tube. The formula is as follows: Round tube weight: (outer diameter-thickness)*thickness*6*0.02491 For example, the cross-section is 38mm*25mm Stainless steel welded pipe, thickness 1.4mm, length 6000mm, we can use the formula: (38+25)*2/3.14-1.4)*1.4*6*0.02491, the calculated theoretical weight is 8.10 kg/piece. When we are not sure about the thickness of the pipe, we can use a scale to weigh the weight, and then use the above formula to calculate, we can clearly know whether the stainless steel welded pipe we buy reaches the thickness promised by the merchant, and will not be deceived by some unscrupulous merchants.
