AWWA standards describe minimum requirements and do not contain all of the engineering and administrative information normally contained in specifications. Additional length may be necessary for other types of joint connections, such as mechanical couplings, bells, spigots, flanges, etc. Type of fitting required i. The optimum radius for a fabricated elbow based on these considerations is 2. The Standards Committee on Steel Pipe, which developed this standard, had the following personnel at the time of approval: Refer to Figure 1F.
Revision of Table 2. Accordingly, each user of this standard is responsible for determining that the standard’s provisions are suitable for and compatible with awwq user’s intended application. The use of A W A standards is entirely voluntary.

This radius is recommended as a standard for water transmission lines where space requirements permit. 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. Refer to Figures 1A and 1B. If the outside diameter of the pipe is larger than the nominal c20, the dimensions can be calculated from the appropriate formulas.
Minimum dimensions for 90″ wyes are stated in Table 1. Minimum dimensions for laterals of unequal diameters and suitable for angle 8 of 30″ to 70″ are stated in Table 1. ANSI procedures require that action be taken to reaffirm, revise, or withdraw this standard no later than five years from the date of publication. Use of This Standard. An American National Standard is intended as a guide to aid the manufacturer, the consumer, and the general public.
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. Refer to Figure lD, Case 1 [equal diameters]. In certain applications, compound elbows and reducing elbows may be used.

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.
Miter welds greater than Wise, Canus Industries Inc. Expansion of Figure 3 to include sizes to in. Major c2208 made to this standard in this edition include the following: Deletion of Table 4. In small diameters 4-in.

Purchaser Options and Aewa. 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. It is not a specification. Three- four- and five-piece elbows: Minimum dimensions for tees and crosses are stated es in Table 1.
It is not intended to be a standard for wall thickness, pressure ratings, and structural or hydraulic design. Warren, Tetra Tech Inc. Some variations from this format may be found in a c2088 standard. Minimum dimensions for laterals of equal diameters and suitable for angle 6 of 30″ to 70″ are stated in Table 1. Steel pipe has been used for waterlines in the United States since the s.
This standard has no applicable information for this section. Spigot ends may also be miter cut, provided that bell to spigot tolerances are maintained. Many configurations of fittings are possible and alternatives to this standard may be agreed upon between the purchaser and manufacturer. For elbows in plant piping, where space is qwwa, a radius of less than 2. Refer to Figure 1A. Dimensions A and B can be calculated using the following formulas: These revisions include the following: Addition of a foreword to provide the history of a standard and major revisions.
In any case of conflict, the requirements f208 this standard shall prevail. Satyarthi, Baker Coupling Company Inc. A factor, f, was introduced in the new Table 1 to facilitate the use of formulas for computing fitting dimensions and provided formulas for elbow layout to facilitate the design of elbows not tabulated.
When swwa outlet diameterless than the run diameter refer to Figure lD, 0 is Case II, unequal diametersminimum dimensions G,Go, and HL can be calculated using the following formulas:
