A ductile iron mechanical joint is a mechanical connection device used to connect pipes or equipment. Ductile iron is a high-strength cast iron material, and its comprehensive performance is close to that of steel, so it is widely used in situations that require high strength, high toughness, and high wear resistance. A ductile iron mechanical joint is mainly used to connect ductile iron pipes or pipe fittings with flanged pipes, valves, or equipment.
Ductile iron mechanical joint function
The main role of a Ductile iron mechanical joint is to connect and seal pipeline systems. has the characteristics of anti-corrosion, wear resistance, high-temperature resistance, and so on. It is widely used in pipeline systems of water supply, drainage, gas, petroleum, chemical industry, and other fields.
The flange connects the ductile iron mechanical flange, and the two sections of pipe are connected together, this connection is firm, and the sealing is good and easy to install. The characteristics of flanged ductile iron pipe include high strength, good toughness, and corrosion resistance, which make it in all kinds of harsh environments maintain good performance. In addition, ductile iron mechanical flange also has the characteristics of large radial compensation, easy installation, and maintenance, good sealing performance, long service life, and provides a guarantee for the safe operation of the pipeline system.
Advantages and features
The advantages of Ductile iron mechanical joints mainly include high strength, high toughness, corrosion resistance, wear resistance, fatigue resistance, and good high-temperature resistance and compressive strength.
Ductile iron mechanical joint is known for its excellent mechanical properties. Its tensile strength is as high as over 600MPa and its elongation exceeds 10%. These characteristics enable it to meet the needs of use under various complex working conditions. Compared with traditional gray cast iron flanges, Ductile iron mechanical joints have significant advantages in strength and toughness, and can withstand harsh environments such as high temperature, high pressure, and corrosion, ensuring the normal operation of equipment. In addition, it also has good corrosion resistance and wear resistance and can be used for a long time in harsh environments without damage.
