Hydraulic fluid power square flange clamps connection
Metric square hydraulic flanges fittings are 4 bolt flange dimensions, according to ISO 6164 standards. It is the square pattern block flanges for the hydraulic applications to be the seal of motors, pumps, etc in mobile and industrial pipeworks equipment.
The dimension of the ISO square flange clamp is different from SAE J518 standard size chart, four-screw one-piece flange connections is used for high pressures of 42 MPa. Size from DN 25 to 80.
Working pressure is based on ferrous material of flange clamps, flanged head, screw, and port. minums
Square flange coupling connection assembly types as follows:
1. Flanged joint assembly with butt-weld
2. Flanged connection assembly to a port
Components of ISO square flange connection systems including:
1. Square Flange Clamps
2. Square Flange Adapters (flange head with or without groove)
3. O-ring seal
4. Screw
