Spiral Wound Gasket Quote
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.
What to Include in a Spiral Wound Gasket Quote
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.
- Flange standard and size. Common examples include ASME B16.5, ASME B16.47, EN 1092-1, and JIS B2220.
- Pressure class. For ASME flanges this may be Class 150, Class 300, Class 600, or higher. For EN flanges this may be PN 10, PN 16, PN 25, PN 40, or higher.
- Gasket dimensions. Provide ID × OD × thickness in millimeters or inches. State whether the gasket includes a centering ring, an inner ring, or both.
- Winding material. Common options include 304 stainless steel, 316L stainless steel, 321 stainless steel, 347 stainless steel, Monel, and Inconel.
- Filler material. Common options include flexible graphite, PTFE, mica, and ceramic.
- Operating conditions. Include temperature range, pressure range, and the medium sealed.
- Quantity and delivery requirement. State the number of pieces and whether the quote is for a standard catalog size or a custom drawing.
Material Selection for Spiral Wound Gaskets
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 |
Standard and Custom Spiral Wound Gaskets
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.
How to Get a Spiral Wound Gasket Quote
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. COR
