Many times in the piping industry there is a need to make a connection to a pipe where it is not practical or feasible to use a manufactured fitting or it is not possible to do so. These types of connections are sometime called branch and header connections. The “Header” is the main line that is being tied into and the “Branch” is the line come off of the Header. The branch is either the same size as Header or smaller in size.
We will go over three types of templates for making these types connections. We will use all of the tools from the two and three piece 90° turns covered in previous chapters.
