Specs Clarification

I know what SFA means , but cannot help you with SF.

SFA mean, what?

Ask your colleagues and friends. The "S" stands for "Sweet" and with a little imagination you'll get the rest.

Have you tried one of the internet search engines looking at "SF" or even consulted your local design drawings? It might even be a local jargon.

Could mean "Structural Ferrous", or "Shallow Filled". Anyone who gives you a definitive answer cold be (unintentionally) leading you in the wrong direction.

In your reply to this entry, please include some additional detail that describes the context, pipe sizes involved, context (above or below ground, lengths involved and number of bends and fittings.) and anything else that yuo believe will help us visualise what you need. There are literally hundreds who read these things, but with nothing to go on people are only guessing.

Also, I'd suggest that you register, then instead of being an anonymous guest, people will recognise you and help you when they can.

In piping specs if RF stand for "raised face" or BE stand for "beveled end"...my question is SF stands for what?

anyone who knows..

thanks

Interesting. That's two guests asking the same question.....

My guess: Stub Flange (full face).

I don't know is this answer's your question, "SF" is a new abbreviation for me, maybe the owner has built into their pipe specification, if so you got to go thru the "definitions" section of the specification.

The only thing that rings in my mind is, has someone used SF for Smooth Finish? The smooth finish is defined in Raised Face Flange finishing requirement like

"RF" Smooth Finish is the

"Average roughness ("Ra") Maximum Value 125 AARH (3.2 Microns)

maybe this could help you, let me know.

Contact the people who wrote the specifications. They should be able to give you a definitive answer.

SF= STRAIGHT FLANGE

MERO

SF=serrated finish

In a search for SF Flanges, there is a reference to "Suction Flanges SF Series:" there is a reference to SF Pipe Series: and an SF Series Cap Plug (polyethylene). There are nearly 9,000,000 entries for SF with most of those referring either to science fiction of San Fransisco. too may entries, alas, to continue the search for the specific meaning of SF for your question. Whoever had written the spec may have looked at a catalog, found what was required for the job, and specified that item, and not know what the SF means, but it wouldn't hurt to ask the writer of the specification.

SF = square feet. You are assuming from the question that it is related to pipe. It could be in reference to paint coverage.

1" square feet? Hardly makes sense.

If the specification was written by a compentent person, there should be a page at the beginning of the specification that lists the abbreviations used and what they mean. There can be literally hundreds of meanings for the same abbreviation. SF may be a common abbreviation used in your line of work in which case, a definition may not be required. When uncommon abbreviations are used, they need to be defined for the reader. That is just good writing skills.

Anyone who works in chlor-alkali project knows wat is SF?

since i new also in SF...

Maybe before going to guess what SF means, we should try to solve the other enigma: "Chlor". I know of Chlorine, Chloride and some others.

When refereeing to piping, SF maybe similar to To NSF (Sweet fat..., and non sweet fat...) as other poster tried to help you with, which is verified by organoleptic analysis (taste,smell etc.) http://en.wikipedia.org/wiki/Organoleptic or maybe goto http://www.nsf.org/ ... health safety standards for piping.

Hope it helps and maybe even tasty.
