Quick Answer: Need a spiral wound gasket quote? Send the flange standard, pressure class, ID × OD × thickness, winding material, filler material, ring type, operating temperature, pressure, medium, and quantity. CORASEALS supplies standard and custom spiral wound gaskets for flanged joints, heat exchangers, and pressure vessels.
A spiral wound gasket quote should match the gasket style to the flange service conditions. Size and quantity are not enough. The metal winding, filler, ring construction, and flange pressure class affect both sealing performance and price.
Spiral wound gaskets combine a metal strip and a soft filler. The metal strip gives mechanical strength and resistance to blowout. The filler compresses against the flange face to create the seal. A reliable quote depends on accurate application data.
The winding material and filler material must be selected together. A common combination is 316L stainless steel with flexible graphite. A 316L stainless steel and flexible graphite combination is used in many steam, oil, and chemical services. For aggressive acids or oxidizing media, the winding material may need to be a higher alloy or the filler may need to change to PTFE.
| Winding Material | Common Application |
|---|---|
| 304 stainless steel | General water, steam, and oil services |
| 316L stainless steel | Chemical, petrochemical, and marine environments |
| 321 or 347 stainless steel | High temperature services where carbide precipitation is a concern |
| Monel | Salt water and some acid services |
| Inconel | Corrosive and high temperature media |
| Filler Material | Common Application |
|---|---|
| Flexible graphite | Steam, high temperature hydrocarbon, and general plant services |
| PTFE | Aggressive chemicals, acids, and caustic media |
| Mica | Very high temperature services |
| Ceramic | Very high temperature services |
CORASEALS quotes standard flange gaskets by flange size and pressure class. Custom gaskets are quoted by drawing, sample, or measured dimensions. For heat exchangers and pressure vessels, the original drawing or a clear photo with ID, OD, and thickness helps reduce pricing errors.
For a spiral wound gasket quote, send us the gasket type, flange standard, pressure class, ID × OD × thickness, winding material, filler material, ring type, operating temperature, pressure, medium, and required quantity. If you have a drawing or sample photo, include that with the inquiry. CORASEALS will confirm the material combination and dimensions before pricing.
Provide flange standard, pressure class, ID × OD × thickness, winding material, filler material, ring type, operating temperature, pressure, medium, and quantity.
An inner ring prevents inward buckling and protects the sealing element in high pressure or high temperature services. A centering ring helps locate the gasket on the flange. Some general service gaskets use only a centering ring. The flange design and service conditions determine the correct style.
Yes. CORASEALS can quote custom sizes based on drawings, samples, or measured ID × OD × thickness.
Flexible graphite is commonly selected for steam service because it seals well on flanged joints and tolerates high temperatures. The final choice depends on steam pressure, temperature, and the flange system.
Send the flange standard, nominal size, pressure class, and the sealed medium. CORASEALS can help confirm the correct gasket dimensions and material combination for the flange.
