SAE Flanges

We manufacture an array of SAE flanges and Hydraulic flanges which corresponds to relevant international standards. These flanges find application in industries where flanged joints are encountered during the tasks of fabrication & maintenance. Our wide array of SAE Flanges can also be customized as per the drawings and specifications provided by the clients.

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.

The design for the SAE System calls for Forged Flanges to ASTM A 105 with Sleeves made from weldable material. In order to reduce costs, various manufacturer have introduced a two piece system where the sleeve & the Flange were combined into one Piece. Such a system is easily adaptable to both Butt Weld and Socket weld Systems. However in practice, the two piece system is used mainly for Socket Weld Flanges for cost considerations.

Many a times , with the introduction of more corrosive fluids in piping systems, the total joint is not required to be of non -corrosive material, e.g. - Stainless Steel - SS only the sleeves which are wetted by the fluid are required to be of SS. This makes for an economical Joint.

Hydraulic Flanges are available in Steel , Stainless steel - 304 , 316 , Brass Materials.
Hydraulic Flanges are available in various types as below :-

SAE Flanges are designed as per SAE J 518 C standards worldwide & VE-LOCK SAE Flanges can be Interchangeable.

The maximum recommended working pressure is indicated for each types given in catalogues Before selecting a Part , Pls take care of W.P. notification All Pressures indications are based on W. Temp. from - 20 degree C to + 90 degree C The indicated W.P. is refers to only flanges itself

For every single flange that being manufactured by us will be from Low carbon % for Proper welding Application We can Manufacture SAE Flanges from Various Steel materials like - Steel / Stainless Steel -304 or 316 Grades.

Note - Bolts with Grade 10.9 are to be used when the materials for the flanges is high tempered.

All steel SAE Flanges are sealed with O ring . This O rings are Manufactured from NBR or Viton Rubber materials NBR - Shore 90 hardness ( standard) / Viton - 85 -90 Shore Hardness ( Option)

SAE Flanges are available in various conncetions as below :-

Split Flanges are designed as per ISO 6162 - 3000 psi series & 6000 Psi Series only. Split Flanges are used for Hose assembly where easy removal piping can be possible with in close area Split Flanges are in 2 halves attached with Weld nozzle with Allen bolts , Nuts & O ring Seal.
