B16.5 Flange Surface Finish

B16.5 Flange Surface Finish

B16.5 Flange Surface Finish

(OP)
I have a 1977 version of B16.5. In paragraph 6.3.4.1 it states the following about flange facing finish:

"Either a serrated-concentric or serrated-sprial finsh having from 24 to 40 grooves per inch shall be used. the cutting tool employed shall have an approximate 0.06 in. or larger radius. The resultant surface finish shall have a 500 microinch approximate roughness."

If anyone has access to the 1996 version, would you reply with what it says now.

Thanks

RE: B16.5 Flange Surface Finish

Dear owlscreech,
Cl 6.4.4.3 of ASME B16.5a-1998 reads as follows:-
"Either a serrated concentric or serrated spiral finish having a resultant surface finish from 125microin to 250microin average roughness.The no of grooves should be from 45 grooves/in to 55 grooves/in with acutting tool having a nose radius of approx 0.06in or larger."
This finish is ofcourse for  RF flanges.
The surface finishes for T &G and RTJ are 125microin and 63 microin resply.

White Paper - How ESI is Helping Move New Medical Device Product to Market Quicker & More Cost Effic
Early Supplier Involvement has long been a strategy employed by manufacturers to produce innovative products. Now, it almost seems like a necessity. Because decisions made in the design phase can positively affect product quality and costs, this can help add value to OEM bottom lines. This white paper will discuss many facets of ESI, including why it’s so valuable today, what challenges limit the benefits of ESI, how cost is impacted, and more. Download Now
White Paper - Moving to a Driverless Future
This white paper describes what we see as the best practices to support a sustainable engineering process for autonomous vehicle design. It exposes how to use simulation and testing in common frameworks to enable design exploration, verification and validation for the development of autonomous cars at a system, software and full-vehicle level to drive a mature product development process for automated driving.

Research Report - How Engineers are Using Remote Access
Remote access enables engineers to work from anywhere provided they have an internet connection. We surveyed our audience of engineers, designers and product managers to learn how they use remote access within their organizations. We wanted to know which industries have adopted remote access, which software they are using, and what features matter most. Download Now
