molded dual arch rubber expansion joints，Molded double-arch rubber expansion joint，Double spherical rubber expansion joint
EPDM molded dual arch rubber expansion joints，Double spherical rubber expansion joint
The rubber expansion joints are all equipped with ANSI 150# carbon steel 304L, 316L, floating metal flanges and metal fixed rings.
The corrugated tube spherical framework of the rubber expansion joint contains no any metal reinforcement materials.
Instead, it is composed of at least five layers of high-strength nylon synthetic fabric.
Each layer of high-strength nylon fabric is impregnated with rubber or synthetic compounds,
thus ensuring the mobility and flexibility between the high-strength nylon fabrics.
It mainly serves as a buffer, allowing the pipeline to expand and contract freely, thereby ensuring the safety of the pipeline.
