Ease of Installation， Sound Reduction， Vibration Reduction QT450 Patented product Ductile flange Rubber Expansion Bellow From Leading Brand Rubber Expansion Bellow Manufacturer， Welcome to call us to get the newest Infomation
Natural rubber: ordinary water, less than 80 degrees, no corrosion.
Acid and alkali resistant type: lined with polytetrafluoroethylene, strong acid and alkali resistant, high temperature below 120 degrees.
Wear-resisting and negative pressure-resisting type: The inner-lined guide barrel has the function of wear-resisting and vacuum-resisting. The guide barrel is made of carbon steel and stainless steel. The increase of the guide barrel will not affect the damping, noise reduction, elongation, compression, and displacement of the rubber expansion bellows.
Oil-resistant type: NBR production, which content is about 50%, has good resistance to hydraulic oil, lubricating oil, emulsion, and other effects, temperature below 120 degrees.
QT450 ductile iron introduction:
For ductile iron with ferrite type, toughness and plasticity are high. At low temperature, toughness changes to brittleness, but the low-temperature impact value is higher, and has certain resistance to temperature acute change and corrosion resistance. It is widely used in agricultural types of machinery, such as plows, plow columns, differential cases, etc. It is also used as a valve body, high and low-pressure cylinder in general machinery, steel cap of transmission lines, etc.
Ductile iron is a kind of carbon that exists in the form of spherical graphite. Its mechanical properties are much better than gray iron and are close to steel. It has excellent casting, cutting, and wear resistance. It has certain elasticity and is widely used in manufacturing high-grade castings such as crankshafts, gears, pistons, and many kinds of mechanical parts.
The advantages of the rubber flange joint are:
1, small volume, lightweight, good elasticity, easy installation, and maintenance.
2. After installation, it can absorb transverse, axial, and angular displacement caused by pipeline vibration; it is not restricted by pipeline dislocation and flange non-parallel.
3, after installation, it can reduce the vibration and noise generated by pipes and pumps.
4. The inner seamless high-pressure rubber expansion bellows can effectively prevent the corrosion of corrosive medium to the inner wall of the rubber expansion bellows in the pipeline with high-temperature resistance, acid and alkali resistance, and oil resistance, and improve the service life.
5. It has good comprehensive performance, so it is widely used in the chemical industry, construction, water supply, drainage, petroleum, light, and heavy industries, refrigeration, sanitation, water heating, fire protection, electricity, and other basic projects.
6. According to the different materials can be made into acid-resistant, alkali-resistant, corrosion-resistant, oil-resistant, high temperature-resistant, radiation-resistant, wear-resistant, aging-resistant, and other varieties, adapting to a variety of media and environments.
