Advantages Of Flanges And Their Materials And Dimensions

Flanges are used to connect pipes, valves, pumps, and other parts to form a piping system. Flanges are typically screwed or welded. The use of flanges allows a person to easy repair and maintains the pipe system. Instead of taking out the whole pipe for inspection, the small section of the pipe can be inspected to find the fault with the help of flange. The flange will allow easy inspection and cleaning of a pipe.

Two flanges are joined together by bolts by using gasket between them for seal. The flanges are used on chemical industry, petroleum industry, and oil and gas industry. The important types of flanges are slip on flange, welding flange, socket flange, blind flange, lap joint flange, threaded flange etc. There are some special type of flanges that are orifice flanges, expander flanges, reducing flanges, nipoflange, long welding flanges, and neck flanges.

Materials used for flanges –

Flanges are made of steel, aluminum, cast iron, brass, bronze, and plastic materials. The material which is used commonly is forged carbon steel. In addition, some flanges have different internal material, which is different from the material of the flanges. These flanges are called ‘lined flanges ‘.

The material of the flange in most cases is the material of the pipe. During the construction of the pipe, the material of the flange is also determined.

The dimension of the flanges are varies. Each flange has number of standard dimensions. The dimensions of the flanges are same all over the world for smooth operations and repair and maintenance work .the dimension are in millimeters.

The basic dimension of a flange consists of an outside diameter, bolt diameter, thickness and number of bolts and their sizes. The bolts are on the front outside of the flange. The gasket which is used between two flanges also has the same size and bolts as that of flanges.

Advantages of flanges connections –

Smaller pieces of pipe MS Seamless Pipe Dealers in India ( can be manufactured in a factory and transported to any destination with easy. There the pipe can be joined by flanges to create the large pipe system.

There is no need for hydro testing or x ray testing, because the tests are conducted in the laboratory or workshop. Even the painting and blasting is not necessary, as these things are already done in the workshop. The fabrication of small pipes becomes easy when they are joined by flanges. The repair, cleaning and inspecting the fault becomes easy by opening the flanges used at short distances.
