Deletion of Table 4. Addendum 2, was approved on June 4, The standard was approved without further revision on Jan. Computation Method and Formulas for Compound Elbows Refer to Figure 4. 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.
For angle 0 less than 30″, use 30″ lateral wye plus an elbow. Revision of Table 1, deleting v208.
Round off to 12 in. If the radius is less than 2. No part of this publication may be reproduced or transmitted in cc208 form or by x208 means, electronic or mechanical, including photocopy, recording, or any information or retrieval system, except in the form of brief excerpts or quotations for review purposes, without the written permission of the publisher.
The pipe was first manufactured by rolling steel sheets or plates into shape and riveting the seams. For elbows in plant piping, where space is limited, a radius of less than 2. By the early s,both riveted and c280 methods were gradually phased out and welding dominated the pipe-making process. Revisions in the text were approved on Dec. A combination of standard miter cuts and pulled joints may also be used.
Special handling, awws, or testing requirements. Tupac, Chair John H. 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.
For an angle 8 less than 30″, use 30″ lateral wye plus an elbow. The optimum radius for a fabricated elbow aqwa on these considerations is 2. As welding became more universal in pipeline construction and manufacturing, varying steel shapes able to accommodate pipeline hydraulics and locations became more prevalent. Some variations from this format may be found in a particular standard.

The action becomes effective on the first day of the month following the month of Journal AWWA publication of the official notice. 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. Type of end connection d208 i. Over the years, rigid specifications have been developed and new product developments and improvements in manufacturing techniques and processes have adwa established to ensure the purchaser a product of high standards.
Refer to Figures 1A and 1B.
The AWWA standards usually contain options that must be evaluated by the user of the standard. Minimum dimensions for 90″ wyes are stated in Table 1.
Revision of Table 2. In their latest editions, these documents form a part of this standard to the extent specified within this standard. 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.
