Reduced outlet Tee 6" x 6" x 2" is not listed in B 16.9 Stds, does that mean that the tee is not a B16.9 tee? if it is, please explain.

Hello,

Well, it means that the fitting that you want is not standardized by ANSI B16.9. Bottom line is that you will not be able to buy such a fitting so you will have to use a Tee and a reducer (or fabricate the branch connection by welding - See B31.3 Appendix H).

Regards, John.

Weel, I know you can by a 6 in x 2 in reducing tee, check the below link for example, but I am not sure if this tee could be specified as B16.9 Tee.

EHE-

I agree with John. Why not consider a weldolet http://www.bonneyforge.com/branch_prod.cfm?id=2 instead?

If you insist for some reason on having a tee then use an extruded tee.

Agree with others that the best solution might be a std. tee with a reducer on the branch. I say best because you can usually get stock materials unless there is something unusual about the material.

Hi EHE,

I guess what I was trying to say is that if it is not "listed" by B16.9, then it is not a "Standard Component". That being the case it does not comply with the B31 Pressure Piping Codes. If you use a component that is "not listed" then you are responsible to do a "little" extra work. See B31.3, See B31.3 paragraphs 315.3 and 318.1.2 AND especially see paragraph 304.7.2 )pressure design)to see how much is "a little" extra work.

There is a reason why we have Codes and Standards. AND, when the Code (e.g., B31.3) is mandated by a local (municipal, State, Province) building Code, then it has the force of law.

Regards, John.

Thank you guys for taking the time to respond to my question. The original question was[/color] Is a 6" x 6" x 2" reduced outlet tee a B16.9 tee? [color red]I gathered that the answer is no.
I have have been using a weldolet all alone, I was just wondering. I also have been using weld on branch connection (hot tap) for many years to tap into gas lines while in service.
