Flangeolet vs Weldolet was created by Ajak Piper
Good day,
Just wondering, if flangeolet can be forged and supplied by Vendor up to 24", why are for some larger connection (example 40" x 10") , combination of weldolet welded to weldneck flange is used?
Is it just because the branch table in Piping Material Specs indicate for such connection, weldolet shall be used instead of flangeolet?
But again what is the basis of creating the branch table limiting usage of flangeolet to certain sizes (in most project i have worked, up until 2" only)?
Request for your expertise to enlighten me on this matter.
Thank you.
regards,
AjakPiper

Ajak,
You will possibly get a lot of responses to your question that are far off the subject. Don't get discouraged.
My comment is as follows: Consider the possibility that "Large-diameter' (larger than 2") Flange-O-Lets are not available is a cost and demand issue.
You would need to have a long discussion with a manufacturer of these types of combination fittings. You would need to provide them with some "example" size combinations and estimates of hypothetical quantities.
Then you would need to do a one-on-one comparison of standard Weld-O-Let plus Weld Neck Flange fittings plus the joining weld to get a proper cost comparison.
I think, in the end you will find that what is done now (Flange-O-Let available in 2" and smaller) and standard Weld-O-Let plus separate Weld Neck Flange (for all larger sizes) is the most economical option.

Thank you Jop for the explanation.
It was my first thought also that cost and demand were the main reasons.
Can i say that most of the flangeolet supplied is up until 2" because it is usually applied for Instrument connection that require such sizes (2" ans below). Since there is no necessity to have flangeolet larger than such sizes (due to cost), combination of weldolet and weldneck flange are used.
This is because i usually come across flangeolet is called for in the Instrument Hook Up drawing and some chemical injection point.
Thank you.
