QT450 ductile iron flange rubber joint

It is ferritic nodular cast iron with high toughness and plasticity. At low temperatures, the toughness transforms to brittleness, but the low-temperature impact value is high, and it has certain resistance to temperature acute changes and corrosion resistance. It is widely used, in agricultural machinery for share ploughs, plough columns, differential housings, etc.; in general machinery as valve bodies, high and low-pressure cylinders, etc.; it can also be used for steel caps for power transmission lines, etc.

QT450 Ductile Iron Introduction:

It is a ferritic ductile iron with high toughness and plasticity. At low temperatures, the toughness changes to brittleness, but the low-temperature impact value is high, and it has certain resistance to acute temperature changes and corrosion resistance. It is widely used in agricultural machinery for plows, plow columns, differential housings, etc.; in general machinery, it is used as valve bodies, high and low-pressure cylinders, etc.; it can also be used for steel caps for power transmission lines, etc.

Ductile iron is a form of carbon that exists in the form of spherical graphite. Its mechanical properties are far superior to gray iron and close to steel. It has excellent casting, cutting, and wear resistance, and has certain elasticity. It is widely used in the manufacture of crankshafts, gears, pistons, and other high-grade castings and various mechanical parts.

Advantages of Ductile Iron Flange Rubber Joints:

1. Small size, light weight, good elasticity, easy installation and maintenance.

2. After installation, it can absorb the transverse, axial, and angular displacement caused by pipeline vibration; it is not limited by pipeline eccentricity and flange non-parallelism.

3. After installation, it can reduce the noise generated by pipeline pump vibration and has strong vibration absorption capacity.

4. The inner seamless high-pressure rubber joint can more effectively prevent the corrosion of corrosive media on the inner wall of the rubber joint in pipelines resistant to high temperature, acid, alkali, and oil, and improve the service life.

5. It has good comprehensive performance, so it is widely used in basic projects such as chemical industry, construction, water supply, drainage, petroleum, light and heavy industry, refrigeration, sanitation, heating, fire protection, and power.

6. According to different materials, it can be made into various varieties such as acid resistance, alkali resistance, corrosion resistance, oil resistance, high temperature resistance, radiation resistance, wear resistance, and aging resistance, and adapt to various media and environments.

Flexible pipe fittings made of rubber as the main material and formed by vulcanization process, used to compensate for thermal displacement of pipelines, absorb vibration and reduce noise.
