How to divide the steel pipe specification? Professional steel pipe cutting machine factory home Longxin machinery for you to summarize the classification of steel pipe specifications:
The theoretical weight calculation formula of steel tube per meter is as follows:
wy 3.1416 * ρ δ (d- δ) / 1000w- per meter theoretical weight kg / m;
ρ -steel density kg / dm-3 / 7.81 ~ 7.85 ~ 7.91d- the nominal outer diameter of steel pipe;
the nominal wall thickness of δ -steel pipe;
