Flange standards (MOST SIMPLE GUIDE) | ASME B16.5 | ASME B16.47 | ASME B16.34 | ASME B16.36

Flanges are used to connect pipes with each other, to valves, to fittings, and to specialty items such as strainers and pressure vessels.
ASME B16.5 Standard covers Pipe Flanges and Flanged Fittings from NPS 1/2 through NPS 24 Metric/Inch.
ASME B16.5 Standard covers pressure-temperature ratings, materials, dimensions, tolerances, marking, testing, and methods of designating openings for pipe flanges and flanged fittings.
ASME B16.47 (Large Diameter Steel Flanges) is a standard for large diameter steel pipe flanges sized from NPS 26 through NPS 60.
ASME B16.47 Standard covers pressure-temperature ratings, materials, dimensions, tolerances, marking, testing, and methods of designating openings for pipe flanges and flanged fittings.
ASME B16. 36 is often abbreviated and referred to as an ORFF. This threaded orifice flange for metering the volumetric flow rate of liquids and gases through a pipe
ASME B16.34 Valves Flanged, Threaded and Welding End applies to new construction. It covers pressure-temperature ratings, dimensions, tolerances, materials, nondestructive examination requirements, testing, and marking for cast, forged, and fabricated flanged, threaded, and welding end and wafer or flangeless valves of steel, nickel-base alloys, and other alloys Wafer or flangeless valves, bolted or through-bolt types, that are installed between flanges or against a flange are treated as flanged-end valves.

[@mohamedtair5120]

hello Thank you for the video
About the fact that 150 ratings are not covered in the ASME B16.36, i see that that in the scope of latest version of that ASME it is in fact covred in the scope
Plsease cold you share some explanation about that thank you :)

[@janashijin9457]

Hi Asad ..hope you are doing well. Can u please explain difference between class 150 and class 125...and some standard are coming b16.42 for ductile iron and b16,1 for cast iron valves ...

[@dhineshkrishnan812]

Kindly make a video about control valve trim types, stem types and stem coupling types.

[@circulasbutton409]

does this standard apply to frp flanges as well?

[@abdessamedghettas7167]

thanks

[@AsadPassionateEngineer]

Most welcome 😊

Please make video on how to selecting & calculation nozzle (orific dia.) in sefty relief valve

[@FUNNEWS998]

👍👍

[@AsadPassionateEngineer]

Thanks for your constant motivational comments 😊👌

[@ahmedsaidi8852]

Thanks for the vedio.
If I have understand well for orifice plate with pipe taps no need for asme b16.36 flanges. They are required only for orifice with flange taps. That's it or not ??

[@AsadPassionateEngineer]

yes, correct understanding.

[@midhunsarasakshan2515]

[@AsadPassionateEngineer]

Thank you

[@GemmyHeart]

Nice video.Look at me head.

[@AsadPassionateEngineer]

Thank you, I will

[@hamed5635]

I saw in a instruction "common flange" Does it mean a simple flange ?

[@AsadPassionateEngineer]

Can you please elaborate your question ? thanks :)

[@anthonychapman5552]

Hi Asad. Your videos are very informative but may I suggest you speak a little slower so that we may grasp the concepts a bit easier.
Thank you.

[@AsadPassionateEngineer]

Wow !! Anthony Such a beautiful way to address your concern 😊, I will Surely take care of my speed !! thank you !!

[@Srk7028]

ASME B16.5 Vs ANSI B16.5 , what is the difference ?

[@AsadPassionateEngineer]

These both mean the same standard.

[@Srk7028]

@@AsadPassionateEngineer thanks for the reply. Which standard classifies flanges in tables, table E, table F etc. ?
