Theoretical weight of ordinary carbon steel, alloy steel round tube formula:
w=0.02466 (d-s) s ------ density of steel to take 7.85kg/dm?
Note: the weight of each meter kg/m = (OD - wall thickness) * wall thickness * 0.02466 unit to take the millimeters: mm For example, ф219 * 8 round tube weight per meter for
(219-8)*8*0.02466=41.626kg/m
Round pipe can be used for pipelines, thermal equipment, mechanical industry, petroleum and geological drilling, containers, chemical industry and special purposes. The specifications of round pipe are expressed in terms of external dimensions (e.g., outer diameter or side length) and internal diameter and wall thickness, and the dimensions cover a wide range, from capillary tubes with a very small diameter to large round steel tubes with diameters up to several meters.
