watertight connction between flanged tube and flangless tube 1

[Weinstein]

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?

Without knowing your specific configuration (i.e. no sketch), could a tubing flange adapater work for you?

Some data would be useful and a sketch maybe.

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...

In this case, a picture with something to indicate scale in it (ruler?) that is accompanied by some descriptive text in the post may help a lot.

Good luck,

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

Hello all,

thank you for your answers. here's a sketch.

the tube is DN50.

thanks a lot in advance.

Then follow XL83NL's advice. Compression fitting to flange adapter.

Although I can'tget it to work, try "victaulic" for compresion type fittings for lower pressure systems. This can also join two pipes directly without a flange.

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(!!)

XL has good answer - could also Google "restrained flange adapter" (as dependable restraint is often necessary where flanged piping is used)
