Hydraulic Flanges

Hydraulic flanges provide leak-free connections for hydraulic hose, pipe and tube assemblies. A flange is a protruding rim, edge, rib or collar, as on a wheel or a pipe shaft. Flanges are used to strengthen an object, hold it in place or attach it to another object. Hydraulic flanges ensure leak proof joints under severe working conditions.

Hydraulic flanges are mainly 4-bolt flanges available in standard configurations of split flange that is comprised of two separate flange halves and captive flange, a one-piece flange. The bolt-hole dimensions for these flanges are size-for-size identical. Flanges with flareless fittings type can be used as a conversion fitting and thus make piping easy and clean.

Types of Hydraulic Flange

Hydraulic flanges are usually of the following types:

• Split flange halves
• Flange clamp
• Flat socket weld flange
• Flat Female Thread Flange
• Socket weld flanges
• Female Thread Flanges
• Rectangular Flange

Uses of Hydraulic Flange

The hydraulic flange, also referred as four bolt flange connection is a proven leak-free connection. It is specially designed to used for larger sizes, high pressures and assembly in tight quarters. Hydraulic flange has achieved worldwide acceptance in varied industrial applications. The flanged heads in hydraulic flanges are used in those fittings having suitable means for attachment of pipes, tubes, or hoses to provide connection ends. These flanges are intended for application in hydraulic systems, on industrial and commercial products, where the use of threaded connections is avoided.
