NF ISO 6162-2
Hydraulic fluid power - Flange connectors with split or one-piece flange clamps and metric or inch screws - Part 2 : flange connectors for use at pressures of 35 MPa (350 bar) to 40 MPa (400 bar), DN 13 to DN 51
ISO 6162-2:2002 specifies complete general and dimensional characteristics for flange heads, split flange clamps (FCS), one-piece flange clamps (FC) and ports applicable to four-screw, split and one-piece flange clamp type tube and hose connectors for use at pressures of 35 MPa (350 bar) to 40 MPa (400 bar). It also specifies the dimensions of the seals to be used, as well as the grooves to house the seal. ISO 6162-2:2002 also recognizes the need to accommodate metric screw fasteners, as well as to provide a means to use existing inch screw fasteners.

La présente norme fixe toutes les caractéristiques générales et les dimensions des raccordements à brides rectangulaires à 4 boulons pour usages normaux sous pressions 250 et 400 bar. Ces raccordements sont destinés à être utilisés dans les transmissions hydrauliques sur les produits industriels et commerciaux lorsqu'on désire éviter l'utilisation de raccordements filetés.
<p>ISO 6162-2:2012 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 four-screw, split and one-piece flange clamp type tube connectors and hose fittings for use at a pressure of 42 MPa (420 bar ). It also specifies the dimensions of the seals to be used, as well as the grooves that house the seals.</p> <p>ISO 6162-2:2012 also recognizes the need to accommodate metric screw fasteners (type 1) (for DN 13 to DN 76), as well as to provide a means to use existing inch screw fasteners (type 2) (for DN 13 to DN 51).</p> <p>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.</p> <p>Surges of pressure higher than the nominal ratings will 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.</p>
