METALLIC GASKETS

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.

          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.
