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.
