Weld Neck Flange

This flange type is designed to be connected by a butt weld connection to the pipe or equipment requiring a flanged joint. Welding neckprovides good service under variety of temperature and pressure applications. A weld neck flange must specifiy the pipe schedule forthe bore. Due to the welding neck, it is a popular choice on pressure vessels and for creating man-holes etc, These flanges are also

knows as ANSl Flange or ASME B16.5 Flange

Slip On Flange

A slip on flange is designed to slip over the end of pipe. it allows for easy positioning before welding. Both the inside and outside of thepipe is welded on the slip on flange. The pipe is generally inserted all the way, inside the slip on flange, leaving only the gap equivalentto wall thickness of pipe

Lap Joint Flange

Lap joint flanges use a stub end that is welded to the pipe. A ring flange fits loosely around the stub end, permiting easy flangeaignment of the bolt holes. A lap joint flange is also called Van Stone or Stub Flange. The stub ends are available in three styles (TypesA,B, and C) and two lengths (Short and Long)

Threaded Flange

Threaded flange is also called screwed flange or screwed-on flange. This type of flange is used where welding is not an optionThreaded flange is most commonly used on low pressure applications and smaller pipes.

Blind Flange

A blind flange is a solid flange with no bore or threaded hole and is used to close the end of pipe, fitings, valves or equipment. Blindpipe flange is also used for pressure testing equipment. Blind flange comes both as raised face and flat face.

Socket Weld Flange

Socket weld pipe flanges are typically used on smaller sizes of high-pressure pipes. These pipe flanges are attached by inserting thepipe into the socket end and applying fillet weld around the top. This allows for a smooth bore and better flow of the fluid or gas insideof the pipe.
