Flange Parts are important joining function parts, which used in many important connection joint of devices and machinery. It normally connect pipe system with other equipment, valves, etc. while offering reliable connection effect and allows dismissing and changing to improve updating of the joint connection.

So, in some way, flange parts are many choices of devices to replace welding connection.

Below are some of the facts that you may not know about flanges. These key pieces of equipment can be challenging, but they are necessary for the continuing function of the pipeline industry.

The purpose of the flange depends on its design. It can help to increase the strength of the structure in the case of say an iron beam in structural steel. These are often useful in the construction of buildings and houses.

A flange can also be used as a guide to keeping a particular object in place. It is common in train wheels with flanges on either side to prevent the wheels from changing directions. The most common use of a flange is to help attach objects like pipes. With the use of these items, the pipes can be easily disassembled or assembled.


There are two different methods used for the creation of flanges. One is casting, while the other is forging. Both forged and cast flanges can work well, but each of the production method has advantages and disadvantages.

Cast products are essentially created when molten metal is poured into a mold or vessel in order to create the desired shape. Forged products are created when steel ingots or billets are exposed to mechanical and thermal pressures, which manipulate them into different shapes.

The main issue with cast flanges is that they are more prone to internal defects. This means that they cannot be used in extremely high-pressure situations, as they may fail suddenly with no warning. Due to their risk of internal flaws, cast flanges are also more likely to be heavily affected by corrosion.

In contrast, forged flanges are not only more reliable, but ultimately able to withstand more pressure. Forged parts actually have 37% higher fatigue strength, which means that they last longer. Therefore, it’s better to invest in high-strength forged products as they are usually better long term investments when used within high-pressure applications.


Flange distributors typically offer many different types of flanges. There is no single type of flange that is right for every situation. Rather, they need to be selected carefully. If the wrong flange is used in a project, it will fail. Some of the popular types of pipe flanges include blind, weld neck, slip-on, lap joint, threaded, socket, and orifice flanges. Each of these serves a different purpose.

If multiple types of products are needed for one project, it’s wise to work with a single distributor for all of them. This helps avoid sourcing issues and ensures that all of the products are made with the exact same quality standards.


This product is made from a lot of different materials, including aluminum, cast iron, bronze, plastic, carbon steel, and stainless steel. Occasionally, a single flange may be made of multiple materials. This is due to the fact that these products, which are referred to as lined flanges, are essentially constructed within layers of various lining materials. The materials used can have an impact on a product's performance, but the production process is just as important.


It’s important to know that the product you’re buying is of the correct material grade. Otherwise, it can be far too easy for you to buy a flange that is not suitable for your project. The material grade comes in a combination of numbers and letters and is indicative of the use, mechanical properties, and chemical composition of a product. Study material grades carefully before making a purchase decision.
