Parflange F37

The achieved pressure by tightening the flange bolts can be spread on a bigger contact surface of the insert, increasing the solidity of the connection.

The Parflange F37 system is used to connect haydraulic tubes, pipes and components without welding.

Depending on pipe and flange size, the F37 system is approved for pressure ratings up to 420 bar (6000 psi, respectively 42 MPa).

It is commonly used in shipbuilding, offshore and heavy machinery industry for moving and controlling of e.g. cranes and elevators.

Furthermore, the Parflange F37 technology allows to connect tubes and pipes from 16 to 273 millimeter outside diameter (1/2" to 10" flange size).

Advantages of Parflange F37 compared to welded flange connections are mainly in savings on time and costs.

by x-ray graphing) and post-weld acid cleaning is needed, making the connection also more environment-friendly and safer than welding.
