4" 150lb threaded Flange

4" 150lb threaded Flange

4" 150lb threaded Flange

(OP)
Need to know how I can get the ANSI Specs for this flange

RE: 4" 150lb threaded Flange

Just order the ASME B16.5 book

RE: 4" 150lb threaded Flange

Call a Vendor who sells forged steel pipe flanges.  The Vendor can furnish you excerpts, dimensions, ratings, etc.

RE: 4" 150lb threaded Flange

The title of ASME B16.5 is Pipe Flanges and Flanged Fittings
NPS 1/2 Through NPS 24 Metric/Inch Standard.  This standard is about 230 pages.

Let us know if you have a specific question about the 4-inch nominal pipe size Class 150 flange. You may need to clarify your request too.  By threaded I am guessing that you speak of a reducing flange using a 4-inch flange that is threaded for a smaller size.  Is this correct?

BTW, consider discussing flange classes such as Class 150 instead of 150 pound.  Many people use 150# or 150 lb, left over from another era.  The ASME B16.5 flange nomeclature changed from 150 lb to Class 150 with the 1973 revision.

John

RE: 4" 150lb threaded Flange

kingsa,
       Suggest you post this in the ASME Code Issues forum since the Standard for flanges is ASME B16.5.

Amigo forista

Se refiere a Ansi Spec a las dimensiones generales de dicha brida ?

RE: 4" 150lb threaded Flange

jusmmerfield - It's funny that you mention that.  I was born in 1972 and I still most commonly hear them called 150 lb or 300 lb flanges ever since I entered the work force about 10 years ago.  It wasn't until a few years ago that I myself learned the true designations are now Class 150/300.

As a stress guy, I shudder to think what someone wants to use a 4" threaded flange for.
