Tangential Welded-on Outlets for Ductile Iron Pipe

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 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 standardly available in some sizes with some additional outlet size restrictions. (Contact AMERICAN for details.)

JOINTS
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, MJ, Flex-Ring, or Lok-Ring. They can also be furnished with plain ends. The parent pipe can also be furnished with any type of joints.

THICKNESSES
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 Table No. 7-17. Check AMERICAN for higher pressure applications.

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, MJ, Flex-Ring, and Lok-Ring bells. Parent and outlet pipe are normally furnished cement-lined in accordance with ANSI/AWWA C104/A21.4. Contact AMERICAN if other ends, or linings other than cement linings, are desired.

Notes:
*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, don't attach and suspend heavy piping items, etc. from outlet branch.
**Larger-diameter outlets may be available for some pressure and service applications. Check AMERICAN for details.
+"J" dimensions are approximate and are the same for all different outlet sizes on a particular parent pipe size. Check AMERICAN if different dimensions are required.
++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", etc.
Nominal thickness of 4"–54" diameter parent pipe and outlet pipe correspond to Special Class 53. Nominal thicknesses of 60" and 64" parent pipe correspond to Pressure Class 350 as shown in ANSI/AWWA C151/A21.51.
Where flanged welded-on outlets must be installed underground, system design and installation should be such so as to avoid bending loads on the flanged joints and/or outlets. It may be necessary in such cases to locate a flexible joint very close to the outlet. AWWA Manual M41 and the Appendix to ANSI/AWWA C115/A21.15 note that underground use of the flanged joint is generally not recommended because of the rigidity of the joint.
This is a shop-fabricated product and is not intended for field fabrication.
Contact AMERICAN for any applications of any flanged welded-on outlets involving connecting piping, such as pump suction and discharge headers, etc.

Tangential Welded-on Outlets
for Ductile Iron Pipe

Welded-on Outlets for Ductile Iron Pipe | To Top of Page

AMERICAN can furnish tangential welded-on outlets in certain diameters. Pipe with tangential outlets can often be positioned* with the outlets on bottom for blow-offs or on top for air release. Flanged and grooved joints are not available for tangential outlets. Minimum pressure classes and location of outlets are the same as for regular welded-on outlets. This is a shop-fabricated product and is not intended for field fabrication. Parent and outlet pipe are normally furnished cement-lined in accordance with ANSI/AWWA C104/A21.4. Contact AMERICAN if other ends, or linings other than cement linings, are desired.
