Are there any requirements regarding the type of sealing surface for wound gaskets used in shell-and-tube heat exchangers according to JB/T4719? The standard should specify gasket rings with internal reinforcement; I wonder if they can be used for RF-type sealing surfaces?

JB/T4719-92 is generally only suitable for uneven surfaces. RF optional toothed gasket.

Can’t a wound gasket be used for that RF sealing surface? Mainly, in the case of split partition grooves, how should one make a choice?
