Special handling, inspection, or testing requirements. C2088 certain applications, compound elbows and reducing elbows may be used. Revisions in the text were approved on Dec.
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 Elbows – AWWA Mitered Fittings and Pipe
Refer to Figure 1E. Deletion of alternate Table 3.
When the outlet diameterless than the run diameter refer to Figure lD, 0 is Case II, unequal diametersminimum dimensions G,Go, and HL can be calculated using the following formulas: Addition of reducing tees and deletion of smooth 90″ elbow category from Figure 1 and Table 1. Qf is a factor to be used in formulas to calculate design dimensions. Number of pieces or segments for elbows. Until each optional feature is specified by the user, the product o r service is not fully defined.
If the outside diameter of the pipe is larger than the nominal diameter, the dimensions can be calculated from the appropriate formulas.
Design pressure and specifications for pipe to which the steel fitting will connect i. The stipulations of this standard apply when this document has been referenced and then only t o dimensions for fabricated steel water pipe fittings. Satyarthi, Baker Coupling Company Inc. The length of reducers L, is calcu- lated by the following formula.
By the early s,both riveted and lock-bar methods were gradually phased out and welding dominated the pipe-making process. Wise, Canus Industries Inc. In small diameters 4-in.

See Figures 5 and 6 for geometric relationships. Dimensions A and B can be calculated using the following formulas: 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 the standard; American National Standards are subject to periodic review, and users are cautioned to obtain the latest editions.
The commercial designation or dimension by which pipe is designated for simplicity. 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. Revision of Table 2. Round off to 12 in. Card, Brico Industries Inc. 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.
Submittal of shop detail and assembly drawings.
Stoner, Consultant, North Plainfield, N. Radius of elbows i.
AWWA C208-12 DIMENSIONS FOR FABRICATED STEEL WATER PIPE FITTINGS (43208-12)
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. Refer to Figure 1A. Minimum dimensions for reducing tees and reducing crosses are stated 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: This standard has no applicable information for this section. Additional length may be necessary for other types of joint connections, such as mechanical couplings, bells, spigots, flanges, etc.
Addendum 2, was approved on June 4, The following items should be covered in the purchaser’s specifications: The information in Table 1 was changed from a tabular format to a formula format in order to ascertain dimensions for tees, crosses, wyes, laterals, and reducers. This edition approved June 17, In special circumstances where a standard nozzle and 90″ elbow cannot be used, a tangent nozzle may be used. The standard was approved without further revision on Jan. The purpose of this standard is to provide the minimum requirements for the dimensions of fabricated steel water pipe fittings.
Use of This Standard. The action becomes effective on the first day of the month following the month of Journal AWWA publication of the official notice. In their latest editions, these documents form a part of this standard to the extent specified within this standard. This method of fabrication continued with improvements into the s.
Revisions to the text were approved on June 21, ,and incorporated in the sixth and later printings. The pipe was first manufactured by rolling steel sheets or 2c08 into shape and riveting the seams.
For angle 0 less than 30″, use 30″ lateral wye plus an elbow. Minimum dimensions for laterals of unequal diameters and suitable for angle 8 of 30″ to 70″ are stated in Table 1.
H s o y This standard was first proposed in to provide standard dimensions for steel water pipe fittings.
