Stainless steel pipe is a kind of hollow long round steel, which is widely used in industrial transportation pipelines and mechanical structural components such as petroleum, chemical industry, medical treatment, food, light industry, mechanical instrument and so on. When the bending and torsional strength are the same, the weight of the stainless steel pipe is lighter. Therefore, it is also widely used in the manufacture of mechanical parts and engineering structures. Because of different purposes and ways of use, in order to meet the needs, stainless steel pipes have different sizes.

3. Dimensions of stainless steel square tube and stainless steel flat tube:
7×7 10×10 12×12 15×15 15.8×15.8 19×19 20×20 22×22 25×25 30×30 31.8×31.8 35×35 38×38 40×40 50×50 60×60 70× 70 76×76 80×80 90×90 100×100 120×120 125×125 150×150
Thickness: 0.4～8.0mm
Calculation formula: (outer diameter (mm) - thickness (mm)) * thickness (mm) * 0.02507 * length (M) = weight (KG)
Both 316 and 316L use this formula, 304 and 304L use this formula by changing 0.02507 to 0.0249
(D: outer diameter S: wall thickness)
The weight per unit length (per meter) of the steel pipe is:
201:(D-S)*D*0.02466.
304:(D-S)*D*0.02491.
316:(D-S)*D*0.02507.
