　　German standard flange: What is the production process of flange?

Flange as a connection sealing parts, in the production process, if there is a quality problem will leak, resulting in economic losses, environmental damage and even safety accidents, so flange welding and production is very important, then the German standard flange: what is the production process of flange?

German standard flange: what is the production process of flange?

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 is different between them.

Forging flange is through the forging machine countless times beat, so that the internal structure of the steel becomes close, so the mechanical properties will be better, the strength will be high, the forging flange is mainly suitable for those with higher pressure in the pipeline.

First of all, the cylindrical billet is cut down according to a certain size, turned into thermoplastic by heating to a certain temperature, and placed on the cold heading to make the forging machine beat the billet continuously, so that the billet interior is more compact and the mechanical properties are better than the original billet.

2. The round hole on the flange shall be punched out on the billet by the punching machine. The formed blank flange shall be put into the electric furnace for heat treatment to increase the strength of the flange, and the flange blank shall be cut and polished to become a flange that can be used.

Cast flange

3. The casting flange has the characteristics of low manufacturing cost and high efficiency, and can produce flanges with complex shapes. The casting flange is mainly suitable for those pipelines with low pressure.

4. Casting flange is also a commonly used manufacturing process. It melts the metal into liquid steel, pours the steel into a metal mold that is preheated and kept at a constant temperature to form the shape of the flange. After the casting is naturally cooled for a period of time, it can be quickly cooled and demoulded with water, which can also increase the strength of the flange. It can be used after polishing and antirust treatment.

5. Flange this small part, although in the entire product, pipeline or machinery and inconspicuous, but the role played by the flange is very important, the future with the development of flange materials and technology, to ensure that the entire joint connection process more precise and firm, to ensure that people use safe and reliable.

German standard flange: what are the advantages of flange?

1. Flange, also known as flange or flange plate, is the pipe end and pipe end and valve connected to each other parts. The two sides of the flange are connected to the pipe end, and the flange itself has holes. The flanges at both ends are fastened through these holes to achieve the purpose of connecting the pipeline and preventing leakage. Stainless steel flanges are widely used in petroleum, chemical, food manufacturing, construction, shipbuilding, medicine and other industries. The reason why the application range of stainless steel flange is so wide, it is because of the material used in stainless steel flange.

2. The flange is mainly made of stainless steel pipe parts, itself has very excellent performance. Stainless steel flanges can effectively resist corrosion, pitting, and rust during use, and stainless steel is very rigid and difficult to wear. Stainless steel flange is one of the high strength materials in metal materials for construction.
