Product Details

SAE code 61 2-screw bolt flange connections is used as hydraulic flange clamps, only low working pressure rating as like the SAE J518-1 (code 61) connections, but it is not SAE J518-1 4-screw flange connections.

 

Code 61 flange clamps used in the same standards of SAE J518-1 port dimensions, flange head dimensions, also compatible with ISO 6162-1 port connections and flange heads.

 

Material of SAE 2-screw flange clamps connections:

Flange clamps material is carbon steel C45, stainless steel 304, 316 or 316L.

Hexagon head screws or socket head screws of property class 10.9 (minimum)

Washers conform to ISO 7089 Type A, Class 300HV

O-ring Seals is NBR(Nitrile) with a hardness of 90±5 IRHD

 

Corrosion protection

All carbon steel flanges shall be plated or coated with a suitable material that passes a 72-h salt

spray test in accordance with ASTM B117 (ISO 9227).

 

Pressure/temperature requirement

Pressure test: Burst test and cyclic endurance testing shall be conducted in accordance with ISO 19879.

Temperatures: Carbon steel flange clamp connectors used at fluid temperatures between –40°C and +120 ºC; Stainless steel flange clamps used at temperatures between –60 °C and +50 °C.
