Chang Yuan Flex co twin sphere thread union rubber expansion joint is a benchmark in flexible piping solutions designed to meet the most stringent industrial requirements. This design has two spherical elements for superior movement in all directions while preserving strength. The twin sphere configuration permits better axial compression, extension as well as lateral deflection performance for demanding piping systems with thermal expansion, vibration and misalignment properties. The thread union connections allow easy  installation and maintenance saving downtime and labor cost in HVAC and heavy industrial applications.

This twin sphere thread union rubber expansion joint by Chang Yuan Flex Co. uses advanced materials and manufacturing techniques. The rubber body is usually made of EPDM or other special elastomers and reinforced with high-Tensile polyester tire cord for resistance to pressure, temperature variations and chemical exposure. Its twin sphere design distributes stress equally across the joint and extends service life in comparison with single sphere alternatives. Also the thread union feature allows quick and secure connections making it an ideal choice for frequent inspections or replacements.

Chang Yuan Flex co twin sphere thread union rubber expansion joint can meet various industrial needs with high quality standards. Available in sizes from DN25 to DN300, this expansion joint can work at up to 16 bar working pressure and operate at temperatures from -20 to + 110degC depending on model and material choice. The twin sphere design absorbs multi-direction movements such as axial compression up to 30mm, extension up to 20mm and lateral deflection up to + -20mm. That extra flexible nature coupled with the convenience of threaded connections makes twin sphere thread union rubber expansion joint a must have for all modern piping systems.
