How to identify flange parameters?
Thread Content
This post was last edited by outnow2 on 2011-10-21 at 17:52. I’m new to flanges. What do the following two American standard flanges mean? TS B16.5 DN80 150LB WT5 WN RF A350LF2 CL1 H1CSSC10070500VB1-1 11.15H NACE; TS B16.5 DN50 900LB WT7.1 WN R24 A350LF2 CL1 H1CSSC10070500VB1-1 11.16H NACE. I tried to look it up on my own – TS seems to stand for special, B refers to non-ferrous metals. What do LB and WT stand for? It seems to be pounds and thickness, right? What do LF2CL1 and the other terms that follow it mean? I tried to look them up but couldn’t figure out what they meant. Thanks. What’s still unclear to me is 11.15H NACE at the very end
TS: Special equipment mark； B16.5: ASME Flange Standard ； LB: Pressure rating ； I don’t know what it means after that
Reply to 1# outnow2: It’s better to specify all the parameters; otherwise, others can only guess. For example, wn refers to butt welding, while rf denotes the sealing surface of a flange. You put all the abbreviations together; it’s too hard to read.
