Does anyone have a good source for design and fabrication of headers for th= e
rotary? I want to use 321 stainless X .065 wall at the inlet but what
practices should be observed as far as =A0slip joint construction? =A0Do yo= u
expand the tube to fit over the same size? =A0Do you purchase different siz= e
tubes? What is the preferred design of the slip joint? Is wall thickness maintained throughout the length? Thanks for any help
