The SSFL is a line of stainless steel refrigeration flanges, flange kits, and flange unions for refrigeration valves and piping systems. Flanges presently available in the industry are forged steel which can be welded but are highly susceptible to rusting. The standard location of the flanges in the piping system makes them near-impossible to paint, especially considering surfaces are obstructed by rusting steel nuts and bolts. Plating non-stainless flanges is possible but noxious gases are released from the plating burning during welding, possibly bothering welders.
Features:
Can be properly welded to either stainless steel or ordinary steel piping
Available from 3/4'' - 3" pipe sizes
Configurations are 2 or 4 bolt with traditional Henry, Frick, R/S, and Hansen dimensions
Buttweld, socket weld, or NPT threaded connections
Flange kits for valves available: includes a pair of male tongue flanges, gasket, stainless steel nuts & bolts, lock washer
Flange unions available: kits include 1 male tongue and 1 female groove flange, stainless steel bolts, nuts, lock washers and gasket
Threaded versions are made using single-point threading for tight NPT connections
