<< It is extremely important, in the design stages of any project that
involves pressure tapping, that the designer be aware of the size of the equipment that is required to make the tap. For those who work with steel pipe, tapping fittings generally consist of a welded branch connection. However, when tapping into a pipe that is cast iron, asbestos cement or concrete, we cannot, of course, weld the fitting onto the existing header. In this tapping situation one of a great variety of alternate fitting attachment techniques must be used. It is important to understand the different types of fittings that are available and which can be interchanged in the event of an emergency situation. >>

A Code Evaluation of Integrally Reinforced Branch Outlet Fittings WFI
<< A piping branch connection is simply the joining of two pieces of pipe at
some predetermined angle to split the flow of the fluid, gas or particulate flowing in the piping system. Anytime a hole is cut in one pipe to join another to it, the pipe with the hole cut in it has been weakened. The pipe with the hole is commonly referred to as the run pipe. If pipes of the same schedule are connected, welded together without any additional reinforcement at the point of attachment, failure will occur at the point of attachment at a pressure which is lower than the failure pressure of an unweakened pipe. Early piping systems were simply constructed by connecting one pipe to another without any reinforcement at the point of attachment. For example, Roman wooden, clay and stone piping systems most often used a compression joint by forcing the branch pipe into a hole cut in the main run pipe. In the early centuries, when the did not create a serious safety problem. >> Received on Thu Aug 31 16:31:00 2000
