IX seal ring gasket product information

IX seal ring gaskets are solid metallic profiled gaskets and often supplied with corrosion resistant coating.

IX seal ring gasket materials

IX seal ring gasket material is usually chosen to be compatible with the flange material, i.e. SS316 seal ring gasket in SS316 compact flange.
For in service use, Table 1 gives a guideline for seal ring selection.
ix-seal-ring-gasket materialselection

Table 1 – IX seal ring gasket materials selection

Flange material	Service temperature	ring material	ring PTFE colour
Carbon steel	-50°C to +250°C	Carbon steel CS360LT or low alloy steels, e.g. AISI 4140	Blue
Stainless steel	-50°C to +250°C	22Cr Duplex	Yellow
Stainless steel	-50°C to +250°C	17/4-PH	Orange
Stainless steel	-101°C to +250°C	Nickel alloys such as Alloy 625, Incoloy 800, 825 ,or similar	Black

Listed IX seal ring gasket materials may be less resistant to corrosion than the stainless steel of the flanges, and this is justified by the low probability of corrosion due to the stressed contact between heel areas of the mating flanges, and due to the seal at the outer circumference of the flanges preventing ingress of moisture and water. Other materials are available on customer’s requirement.
The thickness of PTFT coating shall be 10 µm to 30 μm. The coating colour of IX ring gaskets shall be in accordance with the requirements of Table 1.
Silver coating available to meet customer's need
Metallic IX seal ring gaskets shall have dimensions and tolerances as specified in Table 2. Medium tolerances to ISO 2768-1 shall be used for non specified tolerances.

Inspection and testing

No special requirements regarding hardness are required for the IX seal ring gasket as opposed to standard ring joint gaskets to ASME B16.20. There is no requirement for Charpy impact testing of seal ring materials.
The IX seal grooves are identical for all pressure classes and dimensions are hence given per DN. The outer diameter DA3 of the grooves and the groove angle αA2 are only valid for the flat face flanges, i.e RI, PS, PB and OS flanges. For flanges with face bevel angle (WN, BL, IF and RT), these dimensions vary with the face angle.
