Plate Flange

Plate flanges are mainly used for light duty, lower pressure or non-critical applications, commonly referring to AS2129, BS10 or AS4087 standards. The manufacturing method involves cutting and machining from plate steel

Forged Flange

 Forged Steel flanges are commonly used and specified in the Oil, Gas, Petrochemical and mining sectors, where pressure, temperature and safety considerations often specify the ANSI B16.5, ASME B16.47 or BS4504 standards. The manufacturing method involves the hot forging of suitable steels prior to final machining.

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 flangealignment 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

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.

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.

Blind pipe 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 the pipe into the socket end and applying fllet weld around the top. This allows for a smooth bore and better flow of the fluid or

gas inside of the pipe.
