Product Description

ASTM A694 Gr.F65 Alloy Steel Flange Square 

ASTM A694 refers to the material of carbon and alloy steel pipe flanges, fittings, valves and parts for high pressure liquid transmissions.
It covers material grades of F42, F46, F50, F52, F56, F60, F65 and F70.


210 Bar 3000 Psi ss400 ss304 ISO 6164 SAE 4 Bolt Square Flange
The 4 bolt flange connections conforming to SAE J518 and ISO 6162-1 and -2 are proven, leak-free connections, especially suited for larger sizes, high pressures and assembly in tight quarters. Threaded port connections such as SAE straight thread O-ring and ISO 6149 are reasonably easy to assemble and provide 6000 psi and higher pressure capability up to size 12 (M27). Beyond this size the pressure rating starts to decrease and assembly torques increase rapidly. The 4 bolt flange port connections provide ability to connect larger sizes and achieve higher-pressure capability at reasonable assembly torques. Because of the lower assembly torques compared to an equivalent size threaded port, these connections are well suited for tight quarters where wrench clearances are limited.
