Load and spring back figures are based on Inconel X750 in the age hardened condition. 321 stainless steel will only generate 1/3 of the given Inconel figures. Actual load figures and to a lesser extend spring back can differ hugely from the given data. Tolerances on groove depth, plating, diametrical clearance and differences in material batches can create differences of up to 100% for the smaller cross sections, down to 50% for the bigger cross section.

Seal Diameter (DSI) 006609 = 66,09 mm, for groove ID 65,66 Ihe seal diameter is always the
inside diameter
without plating. The diameter is calculated as
follows: |

2.39M |
Cross Section Select the proper cross section or axial section (AS) in the table, then select the material code “L, M or H” based on the desired wall thickness. |

Resilient metal seals from High
Tech Metal Seals NV are used in the most extreme environmental conditions.
Spring Energised Metal C Rings are used under extreme conditions where
temperature can range from cryogenic up to extreme high temperatures, such
as 800°C.
To serve the harsh conditions in today’s Oil and Gas exploration, High Tech
Metal Seals NV designs and manufactures resilient metals seals which comply
and exceed the ISO 15848 leakage requirements for valves intended for
application with volatile air pollutants and hazardous fluids. High Tech
Metals Seals are manufactured from high alloy materials so that the finished
product complies with NACE MR0175 requirements. Silver plated Metal O rings
or Metal C Rings, because of ductile layer are successfully used in high
vacuum applications. Silver plated or PTFE coated spring energised C Rings
and Metal C Rings comply and exceed the ISO 15848 leakage requirements, from
cryogenic temperatures up to extreme high temperatures and pressures. In
nuclear applications, particle research, and other radiation application,
typically high load resilient metal seals, such as spring energized metal C
Rings or Metal O Rings, with a ductile layer of silver are successfully
used. High Tech Metal Seals NV, seals for extreme environmental conditions
are particularly suited for high pressure. The system pressure assist in
maintaining intimate contact with the mating flanges.
