This manual provides a review of experience and design theory regarding steel pipe used for conveying water. Major revisions to the third edition included in this edition are: the manual was metricized and edited throughout, a discussion of Chemistry, Casting and Heat Treatment (Sec. 1.3) and a discussion of stress evaluation in spiral-welded pipe (Sec. 1.12) were added to Chapter 1, Table 4-1 was revised to reflect new steel grades and Charpy test requirements for pipe with wall thicknesses greater than 1 - 2 in. (12.7 mm), calculations for external fluid pressure (Sec. 4.4) were revised to include consideration of pipe stiffness added by the cement-mortar coating and lining, in Table 6-1, values of E' used for calculation of pipe deflection were revised to reflect increasing soil stiffness with increasing depth of cover, in Chapter 7, the discussion of ring girder design was revised, and a design example was added, Chapter 9, Fittings and Appurtenances, was revised to reflect the provisions of AWWA C208-96, a new section on installation of flanged joints was added to Chapter 12, and, thrust-restraint design calculations in Chapter 13 were revised.
