Scope

This method supports half-pipe jackets attached to a shell or head with a thickness between 3/16” (19 mm) and 2” (50 mm) inclusive. The half-pipe is limited to NPS 2, NPS 3 and NPS 4. There must be positive pressure in both the vessel and the jacket. The method has some consideration for external loads on the shell or head; but not on the jacket.
