9、具有良好的綜合性能，所以它廣泛用于化工、建筑、給水、排水、石油、輕重工業、冷凍、衛生、水暖、消防、電力等基礎工程。
10、根據材料不同可制成耐酸、耐堿、耐腐蝕、耐油、耐高溫、耐輻射、耐磨、耐老化等各個品種，適應多種介質和環境。
The advantages of double ball rubber joints are:
1, the design of the product itself is longer than that of the single ball type, and has good damping and noise reduction effects.
2. It has good performance of telescopic displacement.
3, the service life is longer than that of the single ball.
4, the probability of using double ball rubber joints abroad is greater than that of single ball rubber joints.
5, small volume, light weight, good elasticity, easy installation and maintenance.
6. After installation, the transverse, axial and angular displacement caused by vibration of pipeline can be absorbed; it is not restricted by the dissymmetry of pipeline and the non-parallel flange.
7, after installation, it can reduce the vibration and noise generated by pipes and pumps.
8. Internal seamless high-pressure rubber joints, choose different rubber materials in high-temperature, acid-alkali resistance, oil-resistant pipelines to effectively prevent the corrosive medium on the rubber joints of the corrosion of the inner wall, improve service life.
9. It has good comprehensive performance, so it is widely used in chemical industry, construction, water supply, drainage, petroleum, light and heavy industries, refrigeration, sanitation, water heating, fire protection, electricity and other basic projects.
10. 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, adapt to a variety of media and environment.
