Rubber expansion joints have been used in place of the traditional all-metal expansion joints to solve problems caused by the thermal and mechanical stresses generated in complex systems. Even though the power generation industry is a main user of rubber expansion joints, the product has found acceptance in many other industries.
1:Our products (with Diameter from DN25mm-- 6000mm) have excellent comprehensive performances ,like good characteristics of resistance of /oil/ heat/acid and alkali, high voltage (1.0-6.4MPa),long-range elasticity, air impermeability, medium, climate and radiation resistance , vibration and noise reduction, etc.
2:It is designed with smooth walls inside and has no influence on flow speed of medium in tests and never rusts either with outer by vulcanization.
