And seriously, logic allows you to be the first to check it ..? Go to a person who knows it, and by the way you will see how it should be done and you will have the answer

I guess hard soldering is not welding.

For a welder, yes, for a layman there are professional services. Ensuring tightness or testing it for an installation operating up to ~ 40mbar, not transmitting stresses other than those resulting from thermal expansion and own weight, is not rocket science. After that, a long time ago, copper and soldering went under the thatch.

It's about an old installation. and moving the stove. I will not do it, only the installer who says that it is not possible to weld gas, but it is electrically welded. ~~With tond~~ Hence my question. Thank you for your opinions.
As in the subject, will it be a permanent and tight connection? Or to look for another professional.

Such a weld should be tested for tightness. There are different methods. He should stamp what he did.

New or modified installations in the apartment must be brazed (copper pipes) or welded (seamless steel pipes). It is not written whether gas or electric welding. threaded connections are allowed in places where welding is not possible (e.g. at a gas meter).
Installation can only be performed by a specialist installer who has a valid exam and will sign the work.

And what, this stump cannot be threaded? Put on nipples, elbows or fittings?

After cutting, plug the hole after the stove connection three meters further, stick to the same connection to the stove and the pipe goes further to the bathroom stove.

And you can not cut it and thread it and insert a tee ?? You will also need some space for welding.

jalop · Answer

You need a professional company. Welding / cutting a hole in the pipe in the present case, I call stupidity. Colleagues do well - fittings and a specialist.

marqqv · Answer

The topic is closed with an electrically welded pipe, without any problems, tightness checked. You do not need a company but a decent professional who knows what he is doing. In general, it is possible to ask for it and it is tight.

I close and greet, thank you for the posts.
