Kammprofile Gasket Without Guide Ring (LS_BST) is manufactured without a guide ring for tongue and groove, or recessed flange applications such as male and female.
Kammprofile Gasket Without Guide Ring (LS_BST) is manufactured without a guide ring for tongue and groove, or recessed flange applications such as male and female.
It is typically used in heat exchanger applications and applied as an upgrade to double jacketed gaskets. It is highly suggested to have the nubbin (if present) machined out as a best practice. Where pass partitions are required, they are also kamm profiled and laminated. They are the same thickness as the ring, and securely held in place with welds.
These gaskets are similar in construction to Style without inner & outer ring , with outer ring, with the addition of pass partitions designed for use in shell and tube heat exchangers. The partitions are typically supplied in double-jacketed construction, using the same material as the spiral wound component.
The LS_RF style gasket shares the same construction features as a standard gasket but is specifically sized to serve as a replacement for flanges machined to accept oval or octagonal ring joint gaskets. The sealing element is positioned between the groove ID in the flange and the flange bore.
Inward buckling of spiral wound gaskets remains a concern in the industry. Various industry committees are actively working to improve standards to address this issue. Some end users avoid using inner rings due to cost or bore intrusion. To meet this need, We offer LS_AB style gasket.
