Dn150 Flange Type Double Ball Flexible Stainless Steel Thread Expansion Rubber
Performance characteristics of double ball rubber joints
1. High elasticity: The double ball design improves the airtightness and waterproof performance of the product, and can also effectively improve the service life of the product and reduce noise.
2. High air tightness: The unique double-layer sealing structure achieves good water tightness and air tightness, making it have excellent sealing performance.
3. Media resistance: According to different media, double ball rubber joints can be made of different rubber materials, such as natural rubber, styrene-butadiene rubber, butyl rubber, nitrile rubber, EPDM rubber, neoprene, silicone rubber, fluorine rubber, etc., which have the functions of heat resistance, acid resistance, alkali resistance, corrosion resistance, wear resistance, oil resistance and so on.
4. Weather resistance: Double ball rubber joints can work normally in the temperature range of -65°C to 200°C, showing good weather resistance.
Application of double ball rubber joints
1. It is suitable for conveying pipeline system with temperature ≤ 120 degrees medium, including seawater, fresh water, hot and cold water, domestic sewage, etc.
2. It is especially used for the quick installation and maintenance of pump valves.
3. In the non-erosion environment of chemical and petroleum equipment, double ball rubber joints can be used for thermal insulation of water pipeline joints and heat resistance and anti-corrosion of cooling tower circulating water pipelines.
In general, double ball rubber joints have become an indispensable part of the piping system due to their excellent performance and wide range of application scenarios.
