Sec. 192.153  Components fabricated by welding.

    (a) Except for branch connections and assemblies of standard pipe 
and fittings joined by circumferential welds, the design pressure of 
each component fabricated by welding, whose strength cannot be 
determined, must be established in accordance with paragraph UG-101 of 
section VIII, Division 1, of the ASME Boiler and Pressure Vessel Code.
    (b) Each prefabricated unit that uses plate and longitudinal seams 
must be designed, constructed, and tested in accordance with section I, 
section VIII, Division 1, or section VIII, Division 2 of the ASME Boiler 
and Pressure Vessel Code, except for the following:
    (1) Regularly manufactured butt-welding fittings.
    (2) Pipe that has been produced and tested under a specification

to which they will be subjected under the anticipated operating 
conditions.
    (c) Orange-peel bull plugs and orange-peel swages may not be used on 
pipelines that are to operate at a hoop stress of 20 percent or more of 
the SMYS of the pipe.
    (d) Except for flat closures designed in accordance with section 
VIII of the ASME Boiler and Pressure Code, flat closures and fish tails 
may not be used on pipe that either operates at 100 p.s.i. (689 kPa) 
gage, or more, or is more than 3 inches (76 millimeters) nominal 
diameter.
