Fabricated Outlets

Minimum nominal thicknesses for both parent and outlet pipe are shown in the following tables. The outlets are rated 200 to 250 psi working pressure, depending on size, as noted in Standard Dimensions. Consult AMERICAN for higher-pressure applications.

System design and installation should be such so as to avoid beam loads or impacts on the outlets. It is particularly important in underground service to use flexible joints, such as Flex-Ring or Fast-Grip, for outlet piping to allow for at least some incidental movement between the parent and outlet piping. It should be noted that AWWA Manual M41 and the Appendix to ANSI/AWWA C115/A21.15 state that underground use of the flanged joint is generally not recommended because of the rigidity of the joint, and AMERICAN concurs with this guidance. Flexible outlet pipe joints should not be modified to make them rigid, nor should they be installed fully deflected.

This is a shop-fabricated product and is not intended for field fabrication.

Consult AMERICAN for any applications of any flanged welded-on outlets involving connecting piping, such as pump suction and discharge headers, etc.

1 Do not attempt to lift or rotate outlet pipes by attaching to or exerting force on the outlet or any branch piping attached thereto. Likewise, do not attach and suspend heavy piping items, etc., from outlet branch.

2 Larger-diameter outlets may be available for some pressure and service applications. Consult AMERICAN for details.

3 Nominal thickness of 4"-54" diameter parent pipe and outlet pipe correspond to Special Thickness Class 53. Nominal thicknesses of 60" and 64" parent pipe correspond to Pressure Class 350 as shown in ANSI/AWWA C151/A21.51.

4 “J” dimensions are approximate and are the same for all different outlet sizes on a particular parent pipe size. Consult AMERICAN if different dimensions are required.

5 Minimum ”B” dimensions are dependent on outlet diameter and are not directly related to parent pipe diameter. For example, a “B” dimension for 6" outlets on all sizes of parent pipe (including 10") is 15 1/2".
