GENERAL, NOTES:

(a) 1 in.= 25.4 mm.

(b)1lb/t =1.4882 kg/m.

(c)Weights (masses) are given in pounds per linear foot (kilograms per meter) and are for carbon steel pipe with plain ends.

(d)Thedifferent grades of stainless steel permit considerable variations in weight (mass). The ferriticstainless steels may beabout 5%less,and the austenitic stainless steels about 2% greater, than the values shown in this Table, which are based on weights (masses) for carbon steel.

NOTES:

(1)These wall thicknesses do not permit threading in accordance with ASME B1.20.1.

(2)These dimensions do not conform to ASME B36.10.
