Use of Seamless Pipe
round of industries use  this product like oil and gas industry,cooler,heat exchanger

Weight of Seamless pipe 36 id and 60 od is approximate  88 kg with length of  5.95 meter

Calculation of MS Pipe have different formula.

How to measure weight of Seamless or erw Pipes

Outer Diameter(OD) - Wall Thickness * Wall Thickness * 0.0075 it gives measurement is kilogram per foot

Now to convert kg/ft to Kg / mtr
Multiply  the kilogram/foot with 3.281 = answer will be in Kg per meter of M S Seamless Pipe or Erw Pipe

ERW Square Pipes

How to Calculate weight for Square and Rectangular pipe

1) First Calculate the OD from which this square can be made

add all the sides o square

Example : 200 * 200 Square weight determination

if we add all the sides it comes to 800

800 * 3.142 =
