Round off to 12 in. By the early s,both riveted and lock-bar methods were gradually phased out and welding dominated the pipe-making process. Minimum dimensions for tees and crosses are stated es in Table 1. Refer awws Figure 1A. Available records disclose installations of steel water pipe as early as Submittal of shop detail and assembly drawings.
Refer to Figure 1F.
In small diameters 4-in. Qf is a aqwa to be used in formulas to calculate design dimensions. In ,lock-bar pipe was introduced and, c2008 ,had nearly supplanted riveted pipe. Major revisions made to this standard in this edition include the following: Radius of elbows i.
The length of reducers L, is calcu- lated by the following formula. Revisions to the text were approved on June 21, ,and incorporated in the sixth and later printings. Until each optional feature is specified by the user, the product o r service is not fully defined. Minimum dimensions for 90″ wyes are stated in Table 1.
Purchaser Options and Alternatives Refer to Figure lD, Case 1 [equal diameters]. Tupac, Chair John H.
Brunzell, Brunzell Associates Ltd. AWWA standards are intended to represent a consensus of the water supply industry that. For angle 0 less than 30″, use 30″ lateral wye plus an elbow.
Other angles from 90″to 30″ may be used. Type of end connection required i.
This standard is intended to serve as a dimensional guide only. The use of A W A standards is entirely voluntary. Tangent dimensions provided in Table 1 or calculated by the formulas are minimum dimensions for fittings with plain ends or beveled ends for field welding.
The purpose of this standard is to provide the minimum requirements for the dimensions of fabricated steel water pipe fittings.
Addition of reducing tees and deletion of smooth 90″ elbow category from Figure 1 and Table 1. Reinforcement of fittings, which may include increased wall thickness, collars, wrapper plates, or crotch plates, is not awa in this standard. Revisions in the text were approved on Dec.
In their latest editions, these documents form a part of this standard to the extent specified within this standard. Spigot ends may also be miter cut, provided that bell to spigot tolerances are maintained. AWWA standards describe minimum requirements and do not contain all of the engineering and administrative information normally contained in specifications. Minimum dimensions for reducing tees and reducing crosses are stated in Table 1.
Refer to Figure 1C. This radius is recommended as a standard for water transmission lines where c28 requirements permit. Minimum dimensions for laterals of equal diameters and suitable for angle 6 of 30″ to 70″ are stated in Table 1.
Computation Method and Formulas for Compound Elbows B IV Modification to Standard 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. For an angle 8 less than 30″, use 30″ lateral wye plus an elbow.
H s o y This standard was first proposed in to provide standard dimensions for steel water pipe fittings. Table 2 was deleted from the standard. Stoner, Consultant, North Plainfield, N.
