One of the widely been used joining equipment available is flanges. They are generally used when the joints are to be connected or needs dismantling. It provides good flexibility for a low level of maintenance. The Flanges are generally used to join the pipe parts with equipment such as valves. Pipeline system may contain a breakup flange that must be maintained regularly during the plant operation.

Flanged joints or connection basically compose of 3 essential independent and separable components known as bolting, gaskets, and flanges. For gaining a high level of joining, the application and selection of the element must be done appropriately. It can be classified as based on facing type, based on connection type, based on material, and based on temperature rating.

The flanges can be produced from low alloy steel, stainless steel, exotic material or combination of material, and carbon steel. It can be covered in various specified fittings. Before the flanges are produced they certain things like bolt circle, outer and inner body diameter, and length of the hub is tested and inspected.

The flanges can be marked using manufacturing logo, material grade, material code, thickness, size, service rating based on pressure-temperature class, and heat no. The compact flanges help in increasing high installation, procurement, and maintenance cost. Thus the material is made of the large diameter of more space is required. With sophisticated designing and installation requirement, the tolerance level can be closely matched with the desired product. This makes it suitable for gas and oil-related applications.

Some of the common flanges types are threaded flanges, socket weld flanges, slip-on flanges, lap joint flanges and weld neck flanges. The flange facing type could be tongue & groove, raised face, flat face, ring joint, and female/male type. The flange face could be a serrated type or smooth type.

The flanges are rated based on pressure-temperature class. It got designed with large diameter flanges with the appropriate pressure-temperature rating.

The Flanges are tested using the test- flaring test, flattening test, hardness test, macro/micro test, and intergranular corrosion test.

After testing, certification is made ready and then packaging in wooden boxes, and crates are done.
