What is the theoretical weight per square meter of the steel pipe diameter of the outer frame and the thickness of the tube wall 3mm 48mm?
The outer steel tube diameter is 48mm, the tube wall thickness is 3mm, the theoretical weight per meter is 3.3291kgCalculation formula: (outside diameter wall thickness) * wall thickness *0.02466(48-3) *3*0.02466=3.3291kg
Formula: outside diameter - wall thickness * wall thickness *0.02466=, weight per meter! : 48-3*3*0.02466=3.3291
Dimensions of ordinary steel tubes (taken from GB/T 17395-1998)The theory of weight / (kg/m) | wall thickness (2.9 3.0mm: 3.33)
