watertight connction between flanged tube and flangless tube
watertight connction between flanged tube and flangless tube
(OP)
Hello all,
I have a flangless tube to install for a short time on a line and I'm strugling to make it watertight.
I tried to make flanged connections where the flange is bolted to the line's flange and the other side is only a simple tube of the same OD & ID of my tube.so the arrangement look like for a butt welding.
did anybody have this problem before?

Data such as size of your "tube", wt, material, flange rating, flange size
There are many screwed adaptors to connect tubes or pipes to flanges or you can just weld it.
Not sure what your problem is exactly...

Technically, the glass is always full - 1/2 air and 1/2 water.

thank you for your answers. here's a sketch.
the tube is DN50.
thanks a lot in advance.

A number of similar systems exist, but tend to have low or no axial strenght, so the pipe needs to be clamped to prevent end cap forces and external forces pulling it out of the joint.
Or you can do (not recomended) what I've seen in some countries where they ran out of mating flanges and just welded the pipe directly onto the flange(!!)
