                  Volume calculation method of material

                  ■ sheet material: V m3=L x W xδ 

                  L—length (m) W—width (m) δ—thickness (m)

                   

                  ■ Pipe: V m3=(D+δ)x δ x 3.142 x L 

                  D—Inside diameter of insulation pipe(m) δ—Wall thickness of insulation pipe (m) L—Length of insulation pipe(m)
