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 neck provides good service under variety of temperature and pressure applications. A weld neck flange must specifiy the pipe schedule for the 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 ANSI 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 the pipe is welded on the slip on flange. The pipe is generally inserted all the way, inside the slip on flange, leaving only the gap equivalent to 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, permitting easy flange alignment of the bolt holes. A lap joint flange is also called Van Stone or Stub Flange. The stub ends are available in three styles (Types A, B, and C) and two lengths (Short and Long).
Threaded flange is also called screwed flange or screwed-on flange. This type of flange is used where welding is not an option. Threaded flange is most commonly used on low pressure applications and smaller pipes.
A blind flange is a solid flange with no bore or threaded hole and is used to close the end of pipe, fittings, valves or equipment. Blind pipe flange is also used for pressure testing equipment. Blind flange comes both as raised face and flat face.
