With the development of the Bessemer process in and the open hearth process in ,steel, the strongest and most versatile refinement of iron, became available for water pipe. Round off to 12 in. Tupac, Chair John H. Three- four- and five-piece elbows: Dimensions A and B can be calculated using the following formulas: Spigot ends may also be miter cut, provided that bell to spigot tolerances c2088 maintained.
Stoner, Consultant, North Plainfield, N. Lateral Less Than 30″ Revisions to the text were approved on June 21, ,and incorporated in the sixth and later printings. H s o y This standard was first proposed in to provide standard dimensions for steel water pipe fittings. A combination of standard miter cuts and pulled joints may also be used.
Qwwa ,lock-bar pipe was introduced and, by ,had nearly supplanted riveted pipe. It is not a specification. Deflection angles up to 5″ can be taken in welded butt joints using miter end cuts qwwa one or both pipe ends, provided that the difference in circumference of the true circle and the ellipse formed by the miter end cut does not result in a joint fit-up that would exceed the allowable plate edge offset see Figure 2A.
Addition of reducing tees and deletion of smooth 90″ elbow category from Figure 1 and Table 1. Other angles from 90″to 30″ may be used.
The existence of a n American National Standard does not in any respect preclude anyone, whether that person has approved the standard or not, from manufacturing, marketing, purchasing, or using products, processes, or procedures not conforming to the standard; American National Standards are subject to periodic review, and users are cautioned to obtain the latest editions.
The following guidelines for dimensioning fabriReferring to Figure 2, c20. Dunham, Montgomery Watson, Bellevue, Wash. Minimum dimensions for laterals of unequal diameters and suitable for angle 8 awws 30″ to 70″ are stated wawa Table 1.
Expansion of Figure 3 to include sizes to in. The revisions consisted of the addition of an explanatory paragraph, changes in the table for fittings for service in transmission and distribution mains, and clarification of the figures detailing the various fittings.
AWWA standards describe minimum requirements and do not contain all of the engineering and administrative information normally contained in specifications. For elbows in plant piping, where space is limited, a radius of less than 2.

As welding became more universal in pipeline construction and manufacturing, varying steel shapes able to accommodate pipeline hydraulics and locations became more prevalent. Dimensions G, Go, and HL can be calculated for other awws diameters and a specific angle between run and outlet using the following formulas: Major revisions made to this standard in this edition include the following: Purchaser Options and Alternatives.
All dimensions for fittings in Table 1 of this standard are based on the nominal diameter being the actual outside diameter OD of the pipe. The stipulations of this standard apply when this document has been referenced and then only t o dimensions for fabricated steel water pipe fittings.
The addendum added a note awa caution to Tables 2A through 2D concerning hoop tension concentration in elbows was with a radius of less than 2. Table 2 was deleted from the standard.
Minimum dimensions for tees and crosses are stated es in Table 1. A W A publication of a standard does not constitute endorsement of any product or product type, nor does AWWA test, certify, or approve any product. Deletion of Table 5.
