What do flange S/40S, A182-F316L SS, RF, 150LB mean respectively?
This is the method for marking ASME B16.5 flanges; you can refer to these standards: ASME B16.5-2003 and MSS SP-25-1998. I hope this is helpful to you!
Flange S/40S ----- SCH40S; the wall thickness of the pipe fittings connected to the flange meets the SCH40S standards (it is made of stainless steel). Material: A182-F316L SS, a type of forged alloy steel. RF-----Flange sealing surface. 150LB---Flange pressure rating
Hehe, I really can’t figure out what type of flange this is: flange S/40S, A182-F316L SS, RF, 150LB. A182-F316L – material standard; SS – stainless steel; RF – sealing surface; 150LB – pressure rating; S40S – wall thickness; it should be WN.
S/40S -----It should be said that the counterpart’s pipe is SCH40. As for whether it’s WN or SO, that wasn’t specified
S/40S ----- SCH40S is a pipe fitting specification for connecting flanges to stainless steel fittings; A182-F316L --- material: SS, meaning stainless steel; RF ---- raised face – flange type; 150LB --- flange pressure rating
Based on your description, it is generally a ANSI B16.5 flange with a pressure rating of 150LB; it is made of 316L stainless steel and is a forged flange, while the pipe fittings used with it have a wall thickness of SCH40S. The sealing surface of RF. As for what kind of format it is, I don’t know. It should be WN or SW, I guess. But it’s more likely to be WN.
