What Is Inconel 625 Spiral Wound Gasket?

Austenitic nickel base Alloy- 625 (UNS N06625) exhibits excellent resistance to oxidation and corrosion under a variety of corrosive conditions. The alloy 625 has exceptional fatigue resistance even at 1100 degrees Celsius. Even when welded, the alloy is resistant to intergranular corrosion. Inconel 625 spiral wound gasket is made of Alloy 625 steel strip and soft filler materials like graphite and PTFE. It has high strength and exceptional aqueous resistance to chloride pitting and crevice corrosion. Molybdenum and columbium’s solid solution effect is primarily responsible for the Alloy 625 spiral wound gasket strength.

What Are the Inner And Outer Rings In Alloy 625 Spiral Wound Gasket?

The inner ring makes up the spiral wound gasket’s both axial rigidity and resilience stronger. Its goal is to lessen turbulence around the flange and prevent excessive compression by high seating stress in high-pressure service. The Alloy 625 spiral wound gasket outer ring, also known as the guide ring is made of carbon steel. The main purpose of this component is to fit the gasket into a bolted flange joint while centering the gasket.

How Much Do UNS N06625 Spiral Wound Gasket Inner ring Compress?

Any gasket must have the ability to be both stiff enough to resist the applied forces without being harmed. Also, it is soft sufficient to compress and conform to the imperfections of the seating surface. A gasket’s “compressibility” is defined as its capacity to deform as desired under a specific load. With constant bolt stress of 25,000 psi for 1/2″, 3/4″, and 1″ for 150, 300, and 600 classes. And 30,000 psi for all other sizes, the UNS N06625 spiral wound gasket inner ring must compress to 0.130″(3.3mm) +/- 0.005″(0.13mm).

Reasons to Use Inconel Alloy 625 Spiral Wound Gasket Without Outer Ring?

Inconel Alloy 625 spiral wound gasket without an outer ring is used on Tongue and groove, male and female, and flat groove flanged connections. This kind of spiral wound gasket performs reliably and ensures a secure seal. Special design considerations are made to the inner ring to lessen the turbulent flow. It can also reduce flange erosion and prevent debris accumulation in the annular space between the pipe bore and the internal diameter. The inner ring in the gasket can also act as a barrier between the sealing element and the medium.

Don’t forget to check the selection criteria of alloy 625 nickel spiral wound gasket inner and outer ring as per ASME b16.20

How to Select an Inconel 625 Alloy Spiral Wound Style RIR Gasket?

  • STEP 1 = Verify the fluid category based on the fluid types being used.
  • STEP 2 = Choose the best pressure/temperature graph for the fluid category. Selectable Inconel 625 Alloy spiral wound-style RIR gasket should then be chosen based on the pressure and temperature applied to the gaskets.
  • STEP 3 = Consult the fluid matching table to see if the gasket you chose in Step 2 is compatible with the fluid you want to use.
  • STEP 4 = To determine whether the gasket can be manufactured, consider the size and shape of the gasket.

The same procedures can be applied when selecting a Nickel 625 spiral wound style R gasket.
