[MW:1835] Re: Fabrication of eccentric reducer, ASME B 31.3

the best way is to manufacture a reducer is  in 2 halves formed from plate. These 2 nos long seams will be acceptable.you need to develop the plate profiles. Talk to any manufacturer of heat exchangers who did kettle type ones, in case you need some guidelines for the above development..

Dear Sir,

I need a help regarding the fabrication of Eccentric reducer. When we
made this with a seamed pipe, on of the cut of the reducer come along
with the seam of the pipe. Our client rejected this reducer due to
this reason.(reducer comes in process piing) What is the procedure we
have to do in this case(NDT methods, like that). Is there any clause
in ASME B 31.3 for this? Is there any clause in ASME Sec VII? Can the
cuts of the reducer be considered as a longitudinal joints?

Thanking You
