What is the production process of flanges?

As a type of connecting and sealing component, if there are quality problems during the production process, flanges may leak, causing economic losses, environmental damage, and even safety accidents. Therefore, the welding and production of flanges are very important. So, what is the production process for flanges?

What is the production process of flanges?

At present, there are two main production processes for flanges: forging and casting. Let's take a look at these two main production processes and see what are the differences between them.

1. Forged flanges are made by countless strikes of forging machines to make the internal structure of steel more compact, resulting in better mechanical properties and higher strength. Forged flanges are mainly suitable for pipelines with high pressure.

Firstly, the cylindrical steel billet is cut to a certain size, heated to a certain temperature to become thermoplastic, and then placed on a cold heading machine to continuously hammer the billet, making the interior of the billet more compact and having better mechanical properties than the original billet.

2. It is also necessary to use a stamping machine to punch circular holes on the flange on the steel billet. The formed blank flange needs to be placed in an electric furnace for heat treatment to increase its strength, and the flange blank needs to be cut and polished into usable flanges.

Casting flanges

3. Cast flanges have the characteristics of low manufacturing cost and high efficiency, and can produce flanges with complex shapes. The cast flanges are mainly suitable for pipelines with lower pressure.

4. Casting flanges is also a commonly used manufacturing process, which involves melting metal into liquid steel, pouring the steel into a preheated and constant temperature metal mold to form the shape of the flange. After the casting is naturally cooled and formed for a period of time, it is quickly cooled and demolded with water, which can also increase the strength of the flange. After polishing and rust prevention treatment, it can be used.

5. Although flanges are not prominent in the entire product, pipeline, or machinery, their role is very important. In the future, with the development of flange materials and processes, they can ensure more precision and firmness in the entire joint connection process, ensuring the safety and reliability of people's use.

What are the advantages of flanges?

1. A flange, also known as a flange or flange plate, is a component that connects pipe ends, pipe ends, and valves to each other. The two sides of the flange are connected to the pipe ends, and the flange itself has holes. The flanges at both ends are fastened through these holes to connect the pipeline and prevent leakage. Stainless steel flanges have a wide range of applications, widely used in industries such as petroleum, chemical, food manufacturing, construction, shipbuilding, and pharmaceuticals. The reason why stainless steel flanges have such a wide range of applications is because of the materials used in stainless steel flanges.

2. Flanges are pipeline components mainly made of stainless steel, which have excellent performance. Stainless steel flanges can effectively resist corrosion, pitting, and rust during use, and stainless steel has strong rigidity and is difficult to wear. Stainless steel flange is one of the high-strength metal materials used in construction.
