Refer to Figure 1A.
In ,lock-bar pipe was introduced and, by ,had nearly supplanted riveted pipe. For angles greater than 70″,use the dimension given for tees. Deletion of alternate Table 3. This American National Standard may be revised or withdrawn at any time. Steel pipe has been used for waterlines in the United States since the s.
In certain applications, compound elbows and reducing elbows may be used. The major revision was to clarify that the standard is a dimensional guide only and that design of fittings should be in accordance with applicable sections of AWWA Manual M Refer to Figure 1F. Miter welds greater than Type of end connection required i.
In special circumstances where a standard nozzle and 90″ elbow cannot be used, a tangent nozzle may be used. 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. Addition of reducing tees and deletion of smooth 90″ elbow category from Figure 1 and Table 1. Major revisions made to this standard in this edition include the following: These revisions include the following: Three- four- and five-piece elbows: Revisions to the text were approved on June 21, ,and incorporated in the sixth and later printings.
AWWA Elbows – AWWA Mitered Fittings and Pipe
The Standards Committee on Steel Pipe, which developed this standard, had the following personnel at the time of approval: The pipe was first manufactured by rolling steel sheets or plates into shape and riveting the seams. Special handling, inspection, or testing requirements. Reinforcement of fittings, which may include increased wall thickness, collars, wrapper plates, awwa crotch plates, is not covered in this standard.
Until each optional feature is specified by the user, the awaw o r service is not fully defined.
Deletion of Table 4. Other angles from 90″to 30″ may be used.
This radius is recommended as a standard for water transmission lines where space requirements permit. Addendum 2, was approved on June 4, With the development of the Bessemer process in and the open hearth process in ,steel, the strongest and most versatile refinement of c2208, became available for water pipe. Dunham, Montgomery Watson, Bellevue, Wash.
The optimum radius for a fabricated elbow based on these considerations is 2. Deletion awwwa 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 awwq number of fittings.
It is not intended to be a standard for wall thickness, pressure ratings, and structural or hydraulic design. AWWA standards describe minimum requirements and do not contain all of the engineering and administrative information normally contained in specifications.
If the radius is less than 2. A factor, f, was introduced in the new Table c2208 to facilitate the use of formulas for computing fitting dimensions and v208 formulas for elbow layout to facilitate the design of elbows not tabulated. Radius of elbows i. Producers of goods made c2008 conformity with a n American National Standard are encouraged to state on their own responsibility in advertising and promotional materials or on tags or labels that the goods are produced in conformity with particular American National Standards.
This method of fabrication continued with improvements into the s. This represents good practice that will assist in maintaining the roundness of pipe ends. Submittal of shop detail and assembly drawings. The AWWA standards usually contain options that must be evaluated by the user of the standard.
The following guidelines for dimensioning fabriReferring to Figure 2, 1. Addition of a foreword to provide the history of a standard and major revisions. Recommended dimensions are shown in Figure 3. This standard has no applicable information for this section.
