The rubber expansion joint from LAD's consists of a flange and a cylindrical structure with two rubber layers: an inner layer that provides a sealing function and an outer layer that protects and supports. LAD uses specialized rubber that is highly resistant to abrasion and corrosion for these joints. Reinforcing ribs are commonly present internally to improve deformation resistance. This flexible joint is widely used in various piping systems due to its excellent flexibility and sealing properties. Its advantages are particularly prominent in high-pressure, low-temperature, and corrosive environments.
