As welding became more universal in pipeline construction and manufacturing, varying steel shapes able to accommodate pipeline hydraulics and locations became more prevalent. 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. Type of fitting required i. American National Standard An American National Standard implies a consensus of those substantially concerned with its scope and provisions.
Lateral Less Than 30″ Minimum dimensions for laterals of equal diameters and suitable for angle 6 of 30″ to 70″ are stated in Table 1. Table 2 f208 deleted from the standard.
Expansion of Figure 3 to include sizes to in. 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 Number of pieces or segments for elbows.
Purchaser Options and Alternatives Card, Brico Industries Inc. Many c28 of fittings are possible and alternatives to this standard may be agreed upon between the purchaser and manufacturer. Addition of a foreword to provide the history of a standard and major revisions.
Stoner, Consultant, North Plainfield, N.
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. AWWA has no responsibility for the suitability or compatibility of the provisions of this standard to any. B IV Modification to Standard Until each optional feature is specified by the user, the product o r service is not fully defined.
With the development of the Bessemer process in and the open hearth process in ,steel, the strongest and most versatile refinement of iron, became available for water pipe. Minimum dimensions for reducing tees and reducing crosses are stated in Table 1.
For elbows in plant piping, where space is limited, a radius of less than 2. Lining and coating required.

Refer to Figure 4. Revisions in the text were approved on Dec. Minimum dimensions for 90″ wyes are stated in Table 1. Use of This Standard A W A publication of a standard does not constitute endorsement of any product or 2c08 type, nor does AWWA test, certify, or approve any product. A combination of standard miter cuts and pulled joints may also be used. Three- four- and five-piece elbows: Actual outside diameters may be larger than the nominal pipe diameter. Special handling, inspection, or testing requirements.
The pipe was first aqwa by rolling steel sheets or plates into shape and riveting the seams. 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 butt joints using miter end cuts of one or both pipe ends, provided that the difference in circumference of the true circle and the ellipse formed by the miter end cut does not result in a joint fit-up that would exceed the allowable plate edge offset see Figure 2A.
The existence of a n American National Standard does not in any respect preclude anyone, whether that person has approved the standard or not, from manufacturing, marketing, purchasing, or using products, processes, or procedures not conforming to awwa standard; American National Standards are subject to periodic review, and users are cautioned to obtain the latest editions.
This radius is recommended as a standard for water transmission lines where space requirements permit. Minimum dimensions for tees and crosses are stated es in Table 1. Submittal of shop detail and assembly drawings. All dimensions for fittings in Table 1 of this standard are based on the nominal diameter being the actual outside diameter OD of the pipe.
Refer to Figure 1F. Refer to Figure 1E.
The action becomes effective on the first day of the month following the month of Journal AWWA publication of the official notice.
