AMERICAN regularly furnishes pipe with welded-on outlets for proven effectiveness and simplicity in layout and installation. Outlets can readily be located at variable positions along the pipeline, and rotation of the pipe before it is assembled in the line can often position the outlet at any desired angle. This section provides detailed tabular data for 90° lateral and tangential welded-on outlets. Lateral outlets from 45°–90° in 15° increments from the parent pipe axis are also available as standard in some sizes with some additional outlet size restrictions. Consult AMERICAN for details.
The outlets are fabricated from centrifugally cast ductile iron pipe, manufactured and tested in accordance with ANSI/AWWA C151/A21.51. They may be furnished with any of AMERICAN’s bell ends, such as Fastite, mechanical joint, or Flex-Ring. They also can be furnished with plain ends. The parent pipe also can be furnished with any type of joints.
This is a shop-fabricated product and is not intended for field fabrication. Welded-on outlets for ductile pipe are produced with qualified procedures and welders as per guidelines contained in ANSI/AWS D11.2, Guide for Welding Iron Castings. Joint materials are furnished with Fastite, mechanical, and Flex-Ring bells. Parent and outlet pipe are normally furnished cement-lined in accordance with ANSI/AWWA C104/A21.4. Consult AMERICAN if other ends or linings other than cement are desired.

1.) The purpose of the 18" outlet diameter line is to provide this data when these standard outlets are applied on 30" and larger parent pipes only. Larger-diameter outlets may be available for some pressure and service applications. Contact AMERICAN for details.
2.) 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.
3.) “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. Flanges used on outlets meet ASME B16.1 class 125 requirements and may we welded or threaded on.
4.) 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".
Minimum nominal thicknesses for both parent and outlet pipe are shown in the above table. 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.
Contact AMERICAN for applications of any flanged welded-on outlets involving connecting piping, such as pump suction and discharge headers, etc. Flange outlets supplied by AMERICAN are provided per ANSI/AWWA C151/A21.51 and may be manufactured with either a welded or threaded flange.
