Calculate the app. weight of steel pipes

Before you learn how to calculate the approximate weight of fittings, you need learn to calculate the approximate weight of pipes first, then how to calculate the app. weight of stainless steel pipes? There is a formula to get it. See as follows:

For 316L materail stainless steel pipes: Weight/meter=(OD-WT)*WT*0.02507

Take 219*3.76 316L 6meters pipe for a example:

(219-3.76)*3.76*0.02507*6=121.74kgs

For 304L materail stainless steel pipes: Weight/meter=(OD-WT)*WT*0.02491

Take 219*3.76 304L 6meters pipes for a example:

(219-3.76)*3.76*0.02491*6=120.96kgs
