Fabrication of Welded Steel Wye Branches
Welded steel wye branches are a key component of most water projects where flows must be divided. They are also a specialty item that requires many engineering considerations. The design of intersecting pipes has been studied by many agencies over the years and good design guidance can be obtained from several sources including the American Water Works Association (AWWA) Manual M11, Steel Water Pipe: A Guide for Design and Installation, where the focus is determination of proportions of steel reinforcement necessary to resist internal pressure. However, fabrication of wye branches is often left to the fabricator and little guidance is offered. There are many design related issues requiring a high degree of skill on the part of the fabricator to complete the design and to make it function reliably as a safe, integral part of a conveyance system, as intended by the designer. This paper will address several areas of wye branch fabrication that are not well covered by other sources including steel selection, geometry, welding, heat treatment, and non-destructive testing. Welding code provisions can be a valuable resource and their contribution to steel wye branch fabrication will be explored.
