German standard flange: What is the production process for flanges?
As a connecting and sealing component, flanges can leak during the production process if there are quality issues, 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 of flanges in German standard flanges?
German standard flange: What is the production process for 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 if there are any differences between them.
1. Forged flanges are made by hammering countless times with a forging machine, which tightens the internal organizational structure of the steel, 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 according to a certain size, heated to a certain temperature to become thermoplastic, and 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. Round holes on the flange should be punched on the steel billet through a stamping machine. The formed blank flange should be placed in an electric furnace for heat treatment to increase the strength of the flange. The flange blank should also be cut and polished to become a usable flange.
Cast flange
3. Cast flanges have the characteristics of low manufacturing cost and high efficiency, which can produce flanges with complex shapes. The cast flanges are mainly suitable for pipelines with low pressure.
4. Casting flanges is also a commonly used manufacturing process, which involves melting metal into liquid steel and pouring it 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, they play a very important role. 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 people's safety and reliability in use.
German standard flange: What are the advantages of flanges?
1. A flange, also known as a flange or flange, is a component that connects the pipe end, pipe end, and valve to each other. The two sides of the flange are connected to the pipe ends, and the flange itself has holes. These holes are used to tighten the flanges at both ends, in order to connect the pipeline and prevent leakage. Stainless steel flanges are 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. The flange is a pipeline component mainly made of stainless steel, which has excellent performance. Stainless steel flanges can effectively resist corrosion, pitting, and rusting in use, and the rigidity of stainless steel is strong, making it difficult to wear. Stainless steel flanges are one of the high-strength materials used in construction metal materials.
