DIFFERENT TYPES OF FLANGES


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.
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.
Slip-on Flange Descriptions  is shown in this Article.
THREADED FLANGE

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.

5 Flanges Tools for Pipeline Engineers

Image
“A flange is a mechanical device used to connect pipes, valves, pumps and other equipment to form a piping system. It is connected to valves making it easier for removal and maintenance to the pipework. Flanges are usually welded or screwed. Flanges Provide easy access for cleaning, inspection, and Modification. Flanges joints are made by bolting together two flanges with a gasket between them to provide a seal”. During the construction of new projects or industry say, the petrochemical industry a huge amount of work revolves around Flanges in this industry for connecting the sections of pipe, valves, and pumps. To complete this challenging task high-quality tools and equipments are used by the person responsible for the particular task. So, what tools and equipment are available and where can you get your hands on them? To help you out we’ve put together our list of 5 essential flange tools Flange Facing Machines New flanges can be damaged during transit to the cons...

What is Buttweld Fitting & its Types

Image
What is Buttweld Fitting? A buttweld fitting is a weldable pipe fitting that allows changing the pathway of flow, to reduce or increase the pipe bore size or attach auxiliary equipment. Forged Steel buttweld fittings are manufactured in accordance with ANSI / ASME B16.9. Buttweld fittings  are available in different grades, dimensions, and multiple shapes i.e. they are available in (elbows, tees, caps, reduces and outlets). These pipe fittings are the most common type of welded pipe fitting and are specified by nominal pipe size and pipe schedule . Cast Iron, Aluminum, Glass, Rubber, Alloy, Stainless Steel, Carbon steel are some of the  most common materials used to produce a buttweld fitting,  but to develop the shape of elbows, tees, reducers buttweld fittings use the seamless or welded pipe as the starting material which is then formed through multiple processes. Some of the benefits of Buttweld fittings are; The Welded connection helps to ...
