OEM ODM 317L Stainless Steel Flat Ring Gasket For Tongue And Groove

The soft facing material provides low stress gasket seating, while the serrated geometry of the metal core enhances sealing performance by inducing stress concentrations on the sealing surfaces.  The serrations minimize lateral movement of the facing material, while the metal core provides rigidity and blowout resistance. The gasket exhibits excellent compressibility and recovery characteristics, maintaining joint tightness under pressure and temperature fluctuations, temperature differential across the flange face, flange rotation, bolt stress relaxation, and creep.   Suitable from vacuum to extremely high pressure applications.
 
Style No: RS3-PN 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.
 
Style No: RS3-ZG is constructed with an integral guide ring for aligning purposes. It is suggested to be used in raised face flanges. The gasket is typically designed and sized per EN12560-6 spec for ASME B16.5 flanges, but can be manufactured to fit other standards.

 
Style No: RS3-ZA utilizes a loose fit guide ring. This popular design is preferred for nominal pipe size and pressure class raised face flanges and is used in equipment with excessive radial shear characteristics,thermal cycling,and expansions.
The gasket is typically designed and sized per EN12560-6 spec for ASME B16.5 flanges, but can be manufactured to fit other standards.
 
Kammprofile gaskets are an ideal upgrade for equipment applications where standard spiral wound gaskets, double jacketed designs, and corrugated metallic gaskets are commonly used.
 
Kammprofile RS3-PN dimensions can be the same as Style RS1-R gaskets that are seated in large male/female, large tongue/groove, and small tongue/groove joints. Technically, the dimensions that are specified for large spiral wound ASME B16.20 for ASME B16.47 Series A and B flanges can still apply for the Kammprofile Gaskets per RS3-ZG/RS3-ZA design.

        Corrugated metal is covered with graphite, ceramic or PTFE layer's. An additional finishing layer is applied depending on the requirements of the medium to be sealed. Such gaskets are used on uneven or distorted sealing surfaces, where more elastic materials with better sealing performance are needed.
 
Note: The metal is 0.5 mm thick and the corrugation pitch is 3mm, 4mm or 6mm depending on the width of the gaskets. The thickness of corrugation is approx. 1mm to 1,5mm, depending on gasket size. Corrugated metal can be covered with graphite, ceramic or PTFE layers in thickness 0.5mm, 1mm or 1,5mm.
