This process of precise winding density control provides a gasket designed to meet your specified seating stress and assures consistent sealing of your most critical fluids. Garlock FLEXSEAL® Spiral Wound Gaskets are durable and easily installed and removed. FLEXSEAL® gaskets seal pressures to flange ratings, in accordance with ASME B16.20.
Spiral Wound Gaskets shall be fitted with an inner metal ring (i.e. style CGI). WHEN ORDERING PLEASE SPECIFY EXAMPLE Gasket style Nominal pipe size (NPS) Pressure rating Gasket standard Winding materials Outer ring material Inner ring material Flexitallic Style CGI Spiral Wound Gasket 4 Class 900 ASME B16.20 316L/Flexicarb (FG) Carbon Steel Spiral Wound Finned tubes, Integral Finned tubes, Process Spiral Wound Finned Tube. Fins are basically external surfaces on tube for increasing the surface area of the bare tube, resulting in a compact Heat Exchanger. The method of attaching the fins over tube is of prime importance, since even a slightest air gap between the tube and fins will defeat the whole purpose of fins over the tube.
The core of our spiral heat exchangers is the concentric spiral plate coils nested in the shell. The coils form two completely separated channels with a countercurrent flow arrangement that allows the heat exchanger to achieve very close temperature approaches, making our spiral units excellent for heat
