Parker offers 1-piece full or 2-piece flange kits, and single or double block and bleed flange connections.
Flanges by Parker are Designed to:
- Provide different methods of connecting a tube, hose, pipe or other fittings to standard ports
- Replace weld fittings
- Interface with pressure measuring systems
Hydraulic Flanges are connection between hoses or seamless tubes where easy removal is required with in close quarters in the piping systems. Hydraulic Flanges are mainly used for Bigger sizes of tubes in NB ( Nominal Bore ) sizes. Hydraulic Flanges are used in bigger sizes of Piping joints Where Nut & ferrule assembly is not possible due to higher in Hex section sizes & High torgue require to tighetened / Grip the ferrule in to the tube & lead to loose the joints at High pressure application. In such cases the usage of Flanges with Butt weld or Socket weld has been found to be more practical leading to compact piping installation. Further , the orientation of Hydraulic Flanges joints can be so done to minimize the distance between pipes and provide for a compact installation. CETOP Flanges and ISO 6164 Specify Flanges with Butt weld ends and Square clamping Flanges for 250 bar and 400 bas static working Pressure respectively. These correspond to 160 bar and 315 Bar dynamic Working Pressures. The Flange System consist of a Sleeve to be Butt or Socket Welded to the Pipe and clamped together betwwen two square Flanges by a set of four Hex bolts , Nuts and Spring washers, One of the sleeves carries an O ring groove fitted with an O ring for sealing the interface.
The use of ISO 6164 Flanges has one disadvantage , The size of the Square Flange require a higher pitch between pipes due to the Flange Sizes. In order to reduce the distance between pipes , SAE introduced their own Standards which are now incorporated in to ISO 6162 for the 3000 psi and 6000 psi static Pressure ranges respectivelty. SAE system depends on the same set of butt welding sleeves held together by a set of Split Flange and Solid Flange secured by Hex Bolts and Nut.
