Types of Flanges - Flange Gaskets

Flange gaskets play a critical role across numerous industries by forming a static seal between two flange faces, enduring various operating conditions including fluctuating pressures and temperatures. New Age Gaskets, headquartered in Delhi, has been a key supplier of high-temperature and high-pressure flange gaskets to industries across Punjab, Haryana, Rajasthan, Himachal Pradesh, and other North Indian states. While we've covered the fundamentals of flanges in a previous post, let's now explore the different types of flanges.

A typical flanged connection comprises three essential components: pipe flanges, gaskets, and bolting. The selection of flanges depends on the specific piping system and its intended usage, as there's no one-size-fits-all solution for flanges. The most commonly used flange types include welding neck, slip-on, socket weld, lap joint, threaded, and blind flanges. Additionally, there are specialized flanges tailored to specific requirements, such as orifice, long welding neck, weldoflange/nipoflange, expander, and reducing flanges.

Flanges, along with their accompanying fittings and pipes, can be crafted from various materials such as stainless steel, cast iron, aluminum, brass, bronze, and plastic, with forged carbon steel featuring machined surfaces being the prevailing choice.

When discussing flange gaskets in Rajasthan, three main types come into focus:

Non-metallic gaskets: These are employed with flat-face and raised-face flanges in low-pressure applications.
Semi-metallic gaskets: Suitable for a wide range of operating conditions, including high-temperature and high-pressure applications, these gaskets are favored for raised face, male-and-female, and tongue-and-groove flanges.
Metallic flange gaskets: Paired with specialized flanges mentioned earlier, these gaskets ensure reliable sealing when the correct choice of profiles and materials is made.
