Sec. 192.155  Welded branch connections.

    Each welded branch connection made to pipe in the form of a single 
connection, or in a header or manifold as a series of connections, must 
be designed to ensure that the strength of the pipeline system is not 
reduced, taking into account the stresses in the remaining pipe wall due 
to the opening in the pipe or header, the shear stresses produced by the 
pressure acting on the area of the branch opening, and any external 
loadings due to thermal movement, weight, and vibration.
