Dimensions G, Go, and HL can be calculated for other outside diameters and a specific angle between run and outlet using the following formulas: Reinforcement of fittings, which may include increased wall thickness, collars, wrapper plates, or crotch plates, is not covered in this standard.
Deletion of Table awwwa. Deletion of alternate Table 3. The following guidelines for dimensioning fabriReferring to Figure 2, 1. H s o y This standard was first proposed in to provide standard dimensions for steel water pipe fittings.
Recommended dimensions are shown in Figure 3. Spigot ends may also be miter cut, provided that bell to spigot tolerances are maintained.
Minimum dimensions for reducing tees and reducing crosses are stated in Table 1. Addendum 2, was approved on June 4, Satyarthi, Baker Coupling Company Inc. Refer to Figure 1A. Minimum dimensions for laterals of unequal diameters and suitable for angle 8 of 30″ to 70″ are stated in Table 1.
Computation Method and Formulas for Compound Elbows If necessary to enable the valve operator to clear the outside diameter of the run pipe, a flanged spool should be awwa to extend the connection as required. Some variations from this format may swwa found in a particular standard.

Refer to Figures 1A and 1B. It is not a specification. Refer to Figure lD, Case 1 [equal diameters]. Deflection angles up to 5″ can be taken in welded lap joints using miter-cut bell ends, provided that bell and spigot tolerances are maintained.
See Figures 5 and 6 for geometric relationships. In their latest editions, these documents form a part of this standard to the extent specified within this standard. Many configurations of fittings are possible and alternatives to this standard may be agreed upon between the purchaser and manufacturer. The major revision was to clarify that the standard is a dimensional guide only and awwwa design of fittings should be in accordance with applicable sections of AWWA Manual M Stoner, Consultant, North Plainfield, N.
