Stainless steel gaskets are common in many plants for chemical and petrochemical service. The results of pressure and temperature fluctuations together with bolt stress, relaxation and creep demand a gasket with adequate flexibility and recovery to maintain a seal under varying conditions.
Spiral Wound – Are specially designed in various metals and selections. It has a metal winding, a filler material and a guiding ring. It accommodates class 150 and 300 to 2,500 PSI.
Mica Graphite 350°F
Graphite 99.8% Purity 2200°F
PTFE (Teflon) 500°F
Inner / Outer Ring
Stainless Steel 304/304L/316/316L/321/347
There are many styles of Spiral Wound:
Style WR – Guiding Ring with windings
Style WR1 – Guiding Ring with winding and inner ring
Style W1 – Winding with inner ring only
Style W – Winding only
Ring Type Joint RTJ (Solid Steel) – A solid metal oval/octagonal shaped gasket, generally installed in various machined grooves. It is ideal for low pressure and low bolt loads.
Single/Double Jacket – Has greater compressibility and resilience than solid metal gaskets. It protects the edges and fillers.
Corrugated (Serrated Gasket) – Is made of machined flat, metallic plate with waved or corrugated surface in 90º angles. Has strong corrosive resistance, applicable to high pressure and temperature; is stable and has reliable sealing function.
Kamprofile – Consists of a metal core with concentric grooves on either side with sealing materials. Offers excellent flexibility and has a very wide sealing stress range. High suitability for varying temperatures and pressures.
Exchanger gaskets (metal jacketed) – comes in different profiles and ribs. It is specially designed and widely used on smooth flange applications. Ideal for heat exchangers, flue stacks, boilers, gas-mains, valve bonnets, pumps, etc.
Metal Shim Stock – A wide variety of custom, aluminum, stainless steel shims and shim kits (with/without slots). Stainless steel shims provide years of alignment protection in highly corrosive atmospheres and environments.
