Hydraulic fluid power - Flange connections with split or one-piece flange clamps and metric or inch screws - Part 1: Flange connectors, ports and mounting surfaces for use at pressures of 3,5 MPa (35 bar) to 35 MPa (350 bar), DN 13 to DN 127 - Second Edition
 N 6162-1

Annotation

This part of ISO 6162 gives general and dimensional specifications for flanged heads, split flange clamps (FCS and FCSM), one-piece flange clamps (FC and FCM), ports and mounting surfaces applicable to fourscrew, split and one-piece flange clamp type tube connectors and hose fittings for use at pressures of 3,5 MPa (35 bar1)) to 35 MPa (350 bar). It also specifies the dimensions of the seals to be used, as well as the grooves that house the seals.

This part of ISO 6162 also recognizes the need to accommodate metric screw fasteners (type 1), as well as to provide a means to use existing inch screw fasteners (type 2).

These connections are intended for application in hydraulic systems on industrial and commercial products where it is desired to avoid the use of threaded connectors.

Surges of pressure higher than the nominal ratings can reduce the ability of the flange connections to retain the hydraulic fluid. This needs to be taken into account in the design of the hydraulic system.

1) 1 bar = 0,1 MPa = 105 Pa; 1 Pa = 1 N/m2.
