The pipe was first manufactured by rolling steel sheets or plates into shape and riveting the seams. An American National Standard is intended as a guide to aid the manufacturer, the consumer, and the general public. Minimum dimensions for laterals of equal diameters and suitable for angle 6 of 30″ to 70″ are stated in Table 1. Minimum dimensions for 90″ wyes are stated in Table 1. For angles greater than 70″,use the dimension given for tees.
Qf is a factor to be used in formulas to calculate design dimensions. Card, Brico Industries Inc.

The fitting dimensions shown in Figures 1, 2, 3, 4, and 6 and in Table 1 are the minimum dimensions for fittings with plain ends. For an angle 8 less than 30″, use 30″ lateral wye plus an elbow. Addition of a foreword to provide the history of a standard and major revisions. It is not intended to be a standard for wall thickness, pressure ratings, and structural or hydraulic design. 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.
Lateral Less Than 30″ If the outside diameter of the pipe is larger than the nominal diameter, the dimensions can be calculated from the appropriate formulas. In any case of conflict, the zwwa of this standard shall prevail. This standard has no applicable information for this section. Minimum dimensions for reducing tees and reducing crosses are stated in Table 1. The addendum added a note of caution to Tables 2A through 2D concerning hoop tension concentration awa elbows was with a radius of less than 2.
This standard is intended to serve as a dimensional guide only. Awwa standards are intended to represent a consensus of the water supply industry that. In special circumstances where a standard nozzle and 90″ elbow cannot be used, a tangent nozzle may be used.
Dimensions A and B can be calculated using the following formulas: Wise, Canus Industries Inc. Refer to Figure 1F. Miter welds greater than Some variations from this format may be found in a particular standard.
The aforementioned guidelines for dimensioning fabricated steel pipe elbows represent good practice for water transmission mains. See Figures 5 and 6 for geometric relationships. Major revisions made to this standard in this edition include the following: Spigot ends may also be miter cut, provided that bell to spigot tolerances are maintained.
Use of This Standard. Submittal of shop detail and assembly drawings. This method of fabrication continued with improvements into the s. The following items should be covered in the purchaser’s specifications: Addition of reducing tees and deletion of smooth 90″ elbow category from Figure 1 and Table 1.

Lining and coating required. A factor, f, was introduced in c2088 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. 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.
In small diameters 4-in. Revision of Table 2.
