Wet header – screwed fit or soldered?

[David HaynesParticipant @davidhaynes53962]

Hi folks,

If you have a 3/16" OD copper superheater tail going into the wet header, has anyone used a threaded join rather than the often specified soldered join, in order to facilitate easier superheater removal?

Thanks,

Dave

What choice for type of connection

[julian atkinsParticipant @julianatkins58923]

hi dave,

yes, once, with a male/female connection with cone and union nut.

however there is a limit to how much you can easily undo the union nut with an ordinary spanner from inside the smokebox. also depends what size fingers you have!

cheers,

hi Julian,

Thanks for that. I have made a 2 part wet header, with the front part that is fixed to the superheater tail bolted to the rear part which is in turn soldered to the smokebox tubeplate. So it is possible to take the superheater completely out of the smokebox, in a theory making a screwed connection possible. In the end, I have gone for a soldered joint for the superheater tail.

Thanks for the comment anyway!

Dave
