Instruction for SAE J518 37 Flare Flange Clamps type:
All flare flange clamps of 4-bolt dimensions is the same to SAE J518 / ISO 6162 standards, the differences is connection way: Flare flange system is used for the deburred tube end is flared to 37°, An insert, soft sealed by an O-Ring, is located into each pipe end. By tightening the flanges together, a soft sealed, high pressure tube connection is made.
Material of Flare flange clamps and couplings:
Carbon steel C45; Stainless steel 304, 316 or 316L.
All carbon steel flare flange clamp connection system shall be plated or coated with a suitable material that passes a 72-h salt spray test in accordance with ASTM B117 (ISO 9227).
This flare flange connection is used in high and medium pressure applications, you will found in these industries such as shipbuilding and Offshore, Metals & Mining, Construction machinery. Flare flange system is also suitable for hydraulic, lubrication, hydro carbon, high pressure air, high pressure water cleaning lines etc piping systems.
The difference between SAE flare flange and Split flange clamp system: SAE flange clamps and split flange halves is used for tightening the flanged head with different types of tube connectors and hose fittings, or flange plugs connection; flare flange clamps is used for rigid seamless steel tubing without welding. The same sealing connection is O-ring flat face connection; the same SAE flange port dimensions; the same ISO 6162 and SAE J518 standards.
