The square flange is used to close ends of piping systems. The Square Flange provides a dependable and long lasting isolation point. The Square Flange is similar in diameter to a standard flange and the laying length is compact, making it easily adaptable for your piping systems.

Applications Of Square Flanges

Square Flanges are used in Chemical and petrochemical processing.

Square Flanges are used in electronics.

Square Flanges are used in processing equipment for maintaining product purity in handling foods, synthetic fibers.

Square Flanges are used in marine and offshore engineering.

Dimensions of Square Flanges



A hydraulic flange properly directs the flow of a liquid medium, usually oil, through your hydraulic system. The direction of the oil flow is determined by the position of a spool. A hydraulic system can only function - as per requirements - by using flanges. Thus, you should always look for the correct type of hydraulic flange to serve your intended purpose. The required size is determined by the maximum flow of the hydraulic system through the flange and the maximum system pressure.

Hydraulic flange are available in a variety of sizes and according to multiple International Standards. Hydraulic flanges are available with many different mounting styles: e.g. mounting in pipe lines, with threaded connection as cartridge flanges, subplate mounting or flanged mounting. Hydraulic flanges are subdivided into three main categories: directional control flange, pressure control flange and flow control flanges. All flanges operate a different function in the hydraulic system.

Different flange function in different ways. Check flanges permit free flow in one direction and block flow in the opposite direction. The directional control flange is used to pass on the pressure medium (i.e. flow) in an orderly fashion to a particular direction. Pressure control flange switch (or control) at a certain pressure; the switching pressure may be adjusted on the flange. Flow control flanges regulate the flow this is done by adjusting the size of the bores (orifices)
