Trustworthy Flanges for Offshore Hook-Up?? (Hydrocarbon service)
Trustworthy Flanges for Offshore Hook-Up?? (Hydrocarbon service)
(OP)
Ive been given the task of identifying trustworthy flange-types on the market, suitable for hydrocarbon and utility service, that will provide an alternative to welding and susequently minimise offshore hook-up time.
Does anyone know of any flange products that have a relative success story for offshore service?
Thanks

Like as post by BigInch it would help we could get in the same arena on your requirements.

Your terminology is strange -"Trustworthy"? Anything on the market must meet Code requirements, so by definition is trustworthy. I suggest that you talk to your piping engineer who, I guarantee, will steer you towards ASME B16.5 flanges, unless size, material, cost considerations make these other systems attractive.
Finally, does your company have piping specifications? If not, are you developing them, and if so I would again suggest talking to an experienced piping engineer?

Flanges are always the prefered choice. But if weight is a consideration, then clamp rings are the way to go. But remember that pressure testing with a clamp system can be a problem, because of the difficulty to use blind flanges between fixed sections.
Good pipe support and alignment are a pre-requisite for a large bore clamp system. Otherwise a good seal during pressure testing can be a problem.
Makers of lage bore clamp systems are Galperti, Graylock ( large bore 30").
Weco,ANSON for smaller bore and hammer lock systems. Benefits are quick rig up and down,ideal for temporary packages. Very popular in the oil exploration business and well proven.
