Note : The approximate Kg/Mtr. can be calculated using the formula : Kg/Mtr = (D-t) x t x 0.0246615
D = Outside diameter in mm, T= Thickness in mm
MPa = Megapascal = N/Sq.mm, N = Newton = kg.m/sq.second, s = second, t = thickness, D = diameter, Uti = Up to and including,
YP = specified minimum yield strength (psi), P = test pressure for plain - end pipe, ≥ = means ' Greater than or equal to',
≤ = means 'less than or equal to', YS = Yield Strength, TS = Tensil Strength, OD = Outside Diameter,
NB = Nominal Bore, L = Light series,
M = Medium series, H = Heavy series
