| The jacket pipe terminates on the core pipe a
short distance from the back of the flange by "swaging" or by the use of a
jacket-size welding cap. This construction allows the use of core-size flanges on both
piping and mating equipment. Using equipment with standard, core-size flanges
favorably impacts the cost of a piping system. Swaged Jacketed Piping is used on processes
that have fairly broad temperature envelopes, require the fewest concealed welds to
minimize the possibility of cross contamination, or need only normal heat-soak periods to
achieve melt-out. Note: when Swaged Jacketed Pipe is selected for the purpose of
minimizing concealed welds, close temperature maintenance or very narrow processing
temperature envelopes can be achieved by the strategic use of bolt-on heating jackets (see
Hybrid Jacketed Piping).
