Additional length may be necessary for other types of joint connections, such as mechanical couplings, bells, spigots, flanges, etc. Until each optional feature is specified by the user, the product o r service is not fully defined. Refer to Figures 1A and 1B. Purchaser Options and Alternatives For angle 0 less than 30″, use 30″ lateral wye plus an elbow.
awa In their latest editions, these documents form a part of this standard to the extent specified within this standard. Refer to Figure 1A. The following guidelines for dimensioning fabriReferring to Figure 2, 1. For an angle 8 less than 30″, use 30″ lateral wye plus an elbow.
AWWA C208-12 DIMENSIONS FOR FABRICATED STEEL WATER PIPE FITTINGS (43208-12)
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.
Design pressure and specifications for pipe to which the steel fitting will connect i. The commercial designation or dimension by which pipe is designated for simplicity.
Wise, Canus Industries Inc. The length of reducers L, c20 calcu- lated by the following formula. Producers of goods made in 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 standard is intended to serve as a dimensional guide only.

The aforementioned guidelines for dimensioning fabricated steel pipe elbows represent good practice for water transmission mains. Minimum dimensions for laterals of equal diameters and suitable for angle 6 of 30″ to 70″ qwwa stated in Table 1.
It is not a specification. The use of A W A standards is entirely voluntary. Submittal of shop detail and assembly drawings.
AWWA standards are intended to represent a consensus of the water supply industry that.
Stoner, Consultant, North Plainfield, N. This standard has no applicable information for this section. This edition approved June 17, Add additional length to these dimensions when necessary for flanged, mechanical couplings, or bell and spigot joints, or as needed to meet other design conditions.
The information in Table 1 was changed from a tabular format to a formula format in order to ascertain dimensions x208 tees, crosses, wyes, laterals, and reducers. With the development of the Bessemer process in and the open hearth process awwx ,steel, the strongest and most versatile refinement of iron, became available for water pipe.
A W A publication of a standard does not constitute endorsement of any product or product type, nor does AWWA test, certify, or approve any product. 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. Refer to Figure lD, Case 1 [equal diameters].

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.
