Flange is an important component used to connect pipelines and equipment in pipeline engineering, mainly including Galvanized Pipe Flange Blind Flange， Malleable Iron Floor Flange. Its quality is directly related to the safety and stability of the entire pipeline system. As a high-quality metal material, malleable steel has significant advantages in manufacturing flanges.
What is a flange?
A flange is also called a flange or flange. It is a part that connects shafts to each other and is used to connect pipes, pipe fittings or equipment. As long as the connection parts are bolted and closed around two planes, they can be collectively called flanges.
Classification of flanges:
The basic structure of a End Flange With Bolt Hole Fig consists of a flange body and a connecting thread. The flange body is usually disc-shaped, with a through hole in the center that matches the diameter of the pipe, which is used to connect to the pipe or other equipment. The connecting threads are distributed around the flange, through which the flange can be tightly connected to the pipe or other components with corresponding internal threads.
High strength and pressure resistance, can withstand greater pressure and tension, and stabilize the operation of the pipeline system.
Good sealing, effectively preventing liquid or gas leakage at the connection.
Easy to install, saving installation time and cost.
Wide applicability, threaded flanges meet the connection requirements for conveying liquid media such as water, gas, steam, etc.
Blind flange is a special form of flange.
Features: There is no hole in the middle, which can close or block the interface of the pipeline system to maintain the continuity of the system. Blind flanges are usually made of carbon steel, stainless steel, alloy steel and other materials. Its shape and size are the same as other flanges, but its sealing surface is usually flat.
Blind flanges are widely used in pipeline systems. When repairing or cleaning the system, a pipeline interface can be temporarily closed before subsequent operations.
Blind flanges have the advantages of simple structure, easy use, high reliability, good sealing, and are not prone to leakage and other problems.
Blind flanges have good sealing performance and can be used as a reliable isolation method for systems that need to be completely isolated.
In terms of materials, blind flanges can choose suitable materials such as carbon steel, alloy steel, stainless steel, etc. according to the different use environments and media to meet the needs of different scenarios.
Advantages of Malleable Iron Floor Flange:
1. Excellent mechanical properties
Forged steel has excellent mechanical properties. High strength, high toughness, and good fatigue resistance. It can withstand greater pressure and tension.
Forged steel has a high elastic modulus, which can effectively absorb and disperse vibration and impact in the pipeline system and extend the service life of the flange.
2. High reliability
The flange structure made of forged steel is reasonably designed, fully considering the operating characteristics and needs of the pipeline system.
Precise forging and processing technology enables the flange’s dimensional accuracy and surface quality to reach a high standard.
3. Wear and corrosion resistance
Good wear resistance and corrosion resistance, resisting erosion and wear from a variety of media. Reduces the cost of repair and replacement due to corrosion and wear.
4. High production efficiency
Good plasticity and machinability, able to meet the needs of a variety of processing technologies.
5. Wide range of applications
Forged steel flanges are particularly suitable for some special fields with high material requirements, such as petrochemicals, marine engineering, etc.
