Hi. What's the name of these branch

Hi. What's the name of these branch

Hi. What's the name of these branch

(OP)
Hi. What's the name of these branches guy???

RE: Hi. What's the name of these branch

Commonly called weldolets, though that is officially a brand name of Bonny Forge, so "integraly re-inforced branch fittings" is what B 31.3 calls them.

They are just tacked on at the moment

A closer look makes me think the branch connection is the socket welded version so a "sockolet"

Theres some more information on this post or search weldolet http://www.eng-tips.com/viewthread.cfm?qid=418080

LI,
A Star for you.
I agree on the "sockolet" call.

Sometimes its possible to do all the right things and still get bad results

RE: Hi. What's the name of these branch

Branch connection fitting
90° Branch Outlets – Socket Welding: MSS SP-97

RE: Hi. What's the name of these branch

This looks like a pressure vessel more than a pipe. If it is a vessel, wouldn't they simple be classified as socket nozzles?

RE: Hi. What's the name of these branch

Or nozzolets? smartyglasses

RE: Hi. What's the name of these branch

Or Vessolets.

RE: Hi. What's the name of these branch

gtaw,

Nozzle is typically a piece of pipe welded in, with or without re-inforcement.

A "sockolet" is a single piece item which doesn't need re-inforcement.

This, to me, is a nozzle.

RE: Hi. What's the name of these branch

I've seen nozzles that consisted of weldneck flanges welded directly to the vessel.

The fittings and their design would be dependent on the design code, i.e., whether reinforcement was needed, etc.

I suspect the fitting in the photograph would have different trade names depending on the manufacturer. They look like half socket couplings to me. I couldn't tell if they were integrally reinforced branch fittings from the photograph. I doubt they are IRBFs because I could not see a beveled edge where the tack welds were located and I did not see any radius where the fittings butted up against the vessel wall.

As mentioned, I could not tell if these were branch fitting welded to a run pipe or if they were welded to a vessel.

Merry Christmas everyone.

Best regards - Al

RE: Hi. What's the name of these branch

With respect Al, the bevelled edge can be seen in the fittings further to the right in the photograph. Whether attached to a pipe or vessel, I believe that they are "sockolets" as identified by LittleInch.
Cheers and seasons greetings!

RE: Hi. What's the name of these branch

I think I see what you are referring to. I can't "blow up" the photo and it isn't clear.

However, the term "Sock-o-let" is a trade name. As mentioned previously by Little Inch, B31.3 uses the generic term "integrally reinforced branch fitting".

Merry Christmas!

Best regards - Al
