Red Tee ... how to purchase?

Red Tee ... how to purchase?

Red Tee ... how to purchase?

(OP)
Hello all,
We are buying some red tees, concentric/eccentric reducers,etc, and this in different sizes.... my question is: how to purchase them if I have two different schedules (e.g. Sch 80 x Sch 40).  Should we put both in the purchase order ot the thickest one?
Thanks !!!

RE: Red Tee ... how to purchase?

The question:
"Should we put both in the purchase order ot the thickest one?"

No, you should specify in detail exactly what you want.
Example:
8" sch 80 x 8" sch 80 x 4" sch 40 Carbon Steel (ASTM ???) Concentric Reducing TEE, w/ Bevel Ends

RE: Red Tee ... how to purchase?

To purchase a 8" x 8" x 6" red tee:

"...8" SCH 40 x 8" SCH 40 x 6" SCH 80 red tee..."

Green or blue tees are not acceptable.

Regards,

SNORGY.

RE: Red Tee ... how to purchase?

You must put on the purchase order EXACTLY what you want quoted (and therefore, what you think want purchased.)  Which may even be what you get delivered.   8<)    

As above, if you have two different schedules desired - even the rest of the part uses the same words, you MUST list each part separately.   

If you want a single "red tee" to connect three different pipes which themselves are two different schedules, you need to re-think your "design" - the tee will not isolate the higher pressure from the lower pressure, so any high pressure fluid (or accident) coming down the main run WILL overpressure the low pressure part of the tee.   Buy a simple high pressure (that is, Sch 80) reducing tee of the size and end prep that you want, then change pipe schedules after the tee to the lower pressure (Sch 40) pipe.   

I will make no comment regarding the pressure ratings of green or blue red tees.   8<)

Joke on purchasing dept. wall : Damn , they sent what we ordered !

RE: Red Tee ... how to purchase?

Call your vendor and ask them how they would like to see it.  AND maybe they will get right!!

RE: Red Tee ... how to purchase?

You'd order the Sch.80 Red Tee, and request the supplier to "back taper" the end you wanted to mate-up to the Sch.40. Make sure you request a MIN. 4 to 1 taper when they do this back taper!!!
