Introduction to Flanges

Flanges– Advantages & Disadvantages

Flanges used in different fields such as gas, petroleum, transport, & water. It is also used in chemicals, power generation, & chemical fertilizers. They come in different shapes & types. They also have a various material including stainless steel, low carbon steel, low-alloy steel, non-ferrous steel, & high-alloy steel in accordance with the service environment & type of fluid.

A flange is a way to connect valves, pipes, pumps & other equipment to form a system of pipes. It provides access to modification, inspection or cleaning. They can be screwed or welded. Joining 2 flanges with particular type of seal can put them together.

Different Types of Flanges

– Slip on Flanges
– Threaded Flange
– Lap Joint Flange
– Blind Flange
– Slip-on Flange
– Welded-neck Flange

Materials for Flanges

Pipe flanges are made of materials like cast iron, stainless steel, bronze, aluminum, plastic & many others. However, many of them have machined surfaces & are forged carbon steel.

Applicable Pipe Wall Thickness & Pipe Wall Diameter

It is noted that any size has different wall thickness. However, all wall thickness differs b size depends upon the SCH.NO. They range from (5B, 6B, 8B, 10B, 12B) having a difference in the outer diameter of ASME & JIS pipes even when they have the same diameter. The inner diameter changes due to outer diameter.

Welded Connections vs. Flanged Connections

There are no any specific standards that determine the use of a flange. Because one weld is needed to connect these pipes, customary flanges are used in a newly-installed factory. This saves flange costs. To get more information about flanges visit flanges suppliers in India.

Disadvantages of flanges

– It is expensive to insulate flanged pipes.
– Huge space is needed for flanged pipe systems
– A flange connection can leak

Benefits of flange connections

– Painting & blasting are not necessary.
– Piping spools can be assembled without welding.
– Numerous piping spools can be manufactured.
