It is not intended to be a standard for wall thickness, pressure ratings, and structural or hydraulic design. This awqa of fabrication continued with improvements into the s.

By the early s,both riveted and lock-bar methods were gradually phased out and welding dominated the pipe-making process. For angles greater than 70″,use the dimension given for tees. The purpose of this standard is to provide the minimum requirements for the dimensions of fabricated steel water pipe fittings.

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. Recommended dimensions are shown in Figure 3. Available records disclose installations of steel water pipe as early as Minimum dimension L, can be calculated using the following formulas: The addendum added a note of caution to Tables 2A through 2D concerning hoop tension concentration in elbows was with a radius of less than 2.

Minimum dimensions for tees and crosses are stated es in Table 1. Dimensions G, Go, and HL can be calculated for other outside diameters and a specific angle between run and outlet using the following formulas: AWWA standards describe minimum requirements and do not contain all of the engineering and administrative information normally contained in specifications.

Deletion of Table 5. In practice, fittings are seldom provided as individual pieces as shown but are shop fabricated into full or special lengths of pipe or fabricated into assemblies, combining a number of fittings. Satyarthi, Baker Coupling Company Inc.

Minimum dimensions for 90″ wyes are stated in Table 1. Refer to Figure 1C. If necessary to enable the valve operator to clear the outside diameter of the run pipe, a flanged spool should be used to extend the connection as required. Purchaser Options and Alternatives. Some variations from this format may be found in a particular standard.

Other angles from 90″to 30″ may be used.
