Different Tyoes o Flanges- Pipe Fittings

Different Types of Flanges can be used for Piping a Component as per their Requirements and its specific Functions. It depends mainly on the Required Strength for the Flanged Joint.

Let’s us dive into different types of Flanges which are used for Various Purposes.

WELD NECK FLANGE

A weld neck Flange is used in high Pressure and high/low temperature applications. Different Metals components are combined in order to make a Flange. Weld Neck Flange restricts the flow of fluid coming through a Piping System. The Dimension of the weld neck Flange should match the dimension of the connecting pipe because a negative effect at the Flanged Joints can lead to Erosion/Corrosion of the Metal. Weld Neck Flange as the name suggest has a neck which allows a smooth flow between the Pipes and the Weld Neck Flange. This is to detect Leakages and Welding Defects.

Weight, Dimensions and Specifications of Weld Neck Flanges are shown in this Article

LONG WELD NECK FLANGE

Long weld neck Flanges and weld neck Flanges are similar, the only things which is not common is the Neck. The Neck of a Long Weld Neck Flanges is Extended as compared to Weld Neck Flange and it acts as a Boring Extension. Long Weld Neck Flanges are used on Columns, Vessels, Barrels etc.

SLIP- ON FLANGE

Slip on Flanges also known as Hubbed Flanges is easy to recognize due to its slim and Compact Shape. Smooth Finishing, Corrosion Resistant, Wear and Tear Resistant are some of the key Features of Slip-on Flange. A Slip-on Flange is connected to the Pipes or Fittings with two Welds, on is connected inside and one outside the Flange. The Outside Diameter of a Slip-on Flange is shorter than the bore Size.

THREADED FLANGE

Threaded Flange — Pipe Fittings

Threaded Flanges are joined to the Pipes by screws onto the Flange and are required in explosive areas, such as Oil and gas stations, Big Plants because the execution of such flanges in such an Environment can be dangerous. joined to the Pipes. Threaded flanges are available in sizes up to 4 inches and multiple pressure ratings, however, they are used, mostly, small size piping in low pressure and low-temperature applications, like water and air utility services.

Features of a Threaded Flanges:

· High Level of Performance

· Corrosion Resistance

· Well Finished

SOCKET WELD FLANGE

Socket Weld Flanges are used for Small Size and high-Pressure Piping that do not Transfer high flow of Fluid. Strength of a Socket Weld Flange is similar to Slip-on Flange. This Type of Flange are subject to Corrosion between the Pipe end and the Socket Shoulder. Socket weld flanges are connected to pipes using a single fillet weld executed on the outer side of the flange. This gap shall be left to allow proper positioning of the pipe inside the flange socket after the solidification of the weld.
