Heat Exchanger Fabrication Question?

[sooeey2u]

In a dilemma about exactly how tubes are stuffed in a multi baffle plate heat exchanger. The half plate baffles are already stitch welded on inside of exchanger pipe.

With only a 1/64" clearance in holes for tubes I cannot fathom how one would insert a 35 ft tube thru the full length of a pipe with half baffle plates every 8 ft..

It seems like you would need a broom handle type wood stick aligned thru full length of pipe thru each baffle and then use it as a guide for the tube.

I don't know, have you had any experience around heat exchanger fabrication?

Appreciate your comments and advice,
Robert

Dont worry, just install tie rods, then it will align the holes.
now start tube insertion, dont forget to chamfer the tube end.
if you send drawing or photograph, i will let you know more.
