Ductile Iron Backing Flange is often used to connect two or more pipes. It is a high-strength cast iron material whose comprehensive performance is close to that of steel, with high strength, high toughness, corrosion resistance, wear resistance, fatigue resistance and other characteristics.

 

Features

Ductile Iron Backing Flange is famous for its high strength, high toughness, corrosion resistance, wear resistance, fatigue resistance and other characteristics. These characteristics make it have excellent performance under various complex working conditions. Compared with traditional gray cast iron flange, Ductile Iron Backing Flange has significant advantages in strength and toughness, with a tensile strength of more than 600MPa and an elongation of more than 10%, which can meet the needs of use under various complex working conditions. . In addition, Ductile Iron Backing Flange also has good corrosion resistance and wear resistance, and can be used for a long time in harsh environments without damage.

 

Application

Ductile Iron Backing Flange has a wide range of applications, including but not limited to pipeline systems in petrochemical, electric power, metallurgy, water treatment, construction and other industries.

In the petroleum and chemical industries, it is used to connect various pipelines and equipment and withstand harsh environments such as high temperature, high pressure, and corrosion;

In the power industry, the pipeline system is used to connect boilers, turbines, generators and other equipment to ensure the normal operation of power equipment;

In the metallurgical industry, the piping systems used to connect smelting furnaces, rolling mills, cooling systems and other equipment are subject to high temperature, high pressure and erosion by corrosive media;

In the water treatment industry, it is used to connect pipeline systems such as water supply, drainage, and sewage treatment to ensure the safety and stability of water quality;

In the construction industry, it is used to connect the building's water supply, drainage, fire protection, air conditioning and other piping systems to ensure the normal use of the building.
