Flanges are important components of most mechanical systems. They offer a mechanical means of joining or assembling parts such as pipes, fittings, and valves. Besides, they can also be disassembled when used, making them ideal for use with systems that would require maintenance.

So, what is a flange? What are the types of flanges? What are the considerations when designing flanges? Read on we will provide information to help you make the right manufacturing decisions.

What Is A Flange?

Flanges, meaning rims, are symmetrical disc-like components that are used to attach or seal pipes, containers, or fixed-shaft mechanical pieces. These disc-shaped components are most frequently found in plumbing and are typically used in pairs. There are also different types of fasteners and threaded fixings are used to secure the flanges in place.

In addition, a flange features bolt holes. Two flanges are normally joined to pipe ends with a gasket in between, and the connection between them is made with bolts.

Characteristics Of Flanges

·Flanges have accurately drilled holes for easy assembly.

·They have controlled grain flow for optimal strength and stiffness.

·To facilitate good welding, flanges are machined bevels.

·For unrestricted flow when used for piping system, flanges are smooth and have accurate bore.

·This component has spot-facing to ensure fastener seating stays true and square.

How Does Flange Connection Work?

A flange connection is an assembly involving two pieces of equipment, pipes or pipe fittings, two flanges, flange mats, and bolts. Different types of washers are also used with the flange connection to secure the connection.

Besides, a flange connection culminates in joining two materials using inner and outer lip parts or flanges. For each of the opposing flange faces to form a seal, force (gasket compression or sealing pressure) must be exerted and maintained. To ensure flanges stay in place, they are often bolted with a gasket between the flange faces to form a tight seal. One of the gaskets often used for this sealing is a disk spring, which is a type of spring.
