A WCB body can be substuted for a LCC body up to 89mm OD in a low temp application?
A WCB body can be substuted for a LCC body up to 89mm OD in a low temp application?
(OP)
I am revising my company's piping specification 'CSA Z662 - Pipline risers at low temp. (-45C to 120C)', and I found a note "A WCB body can be substuted for a LCC body up to 89mm OD".
I know WCB body is for regular temp application, so how does this note come from? I just did a quck go through the CSA Z245.15 and did not find any reference. Any help is going to be appreciated.

LCC (or LCB, which has a marginally lower tensile strength, lower yield, and a higher max allowed carbon content compared to LCC), and WCB are very close in chemical compostion, so much so that some raw-material manufacturers dual-certify the same forging/bar/casting as both standards. Still, WCB is not the steel of choice for low temp below -30ºC, so the note you found is odd.
Any particular need to move from LCC to WCB?
Oxidation-proof valves for offshore environments.
