Flanges

Flanges are piping components used for connecting pipes which needs dismantling & periodic maintenance, other piping components like valves, specialties, instrument items like orifice, flow meters etc on to the pipes. A flange is a Ring, Collar, Round Sheet type used to assemble pipes or components, for blocking of pipes or flow etc. There are different sizes and dimensions as per different standards requirements. KPS Forge has abilities to forge all kind of flanges in all grades. The different flanges we manufacturing are:

Weld-Neck Flange
The weld neck (or welding neck) flange is bored to the ID of the pipe and has a high neck to which pipe is welded. Probably the best welding flange available because of its high, heavy neck. Used wherever a sound welded joint connection is needed.

Slip-On Flange
The slip-on flange has a low hub and is bored slightly larger than the OD of the pipe. This flange is welded on both inside and outside of the flange face to prevent leakage. Used in lieu of welding necks when cost or space is a major consideration.

Threaded Flange
Like Slip-on except bore of this flange is threaded to match the pipe size. Used for low pressure systems and where welding could be hazardous.

Socket Weld Flange
The socket weld flange is bored to the ID of the pipe and counter bored slightly larger than the OD of the pipe to allow the pipe to be inserted and welded in place.

Lap joint Flange
Bored slightly larger than the OD of the pipe, the radius on the bottom matches the radius on the stub end. It is slipped over the pipe and a stub end is welded onto the pipe. The flange is then slipped over the stub end and bolted up. Used for systems that need frequent cleaning and/or inspection.

Blind Flange
This flange is a solid circle drilled to match a companion flange. Used to shut off or blank off piping. Custom Flange
