AY type expansion joint pull rod coated with zinc

　　The AY type expansion joint is specially designed to address displacement issues in pipeline systems. It mainly consists of the body, expansion pipe, and sealing components. When the pipeline expands and contracts due to thermal expansion and contraction or mechanical vibrations, the expansion pipe can flexibly respond and compensate for the displacement, effectively alleviating pipeline stress and ensuring stable system operation. Its sealing components have excellent performance, preventing medium leakage. It is worth mentioning that the pull rod of this expansion joint undergoes a special zinc coating treatment, forming a dense protective film with outstanding rust and corrosion resistance, significantly extending the service life of the pull rod and ensuring that the expansion joint can work reliably even in humid and corrosive environments. It is widely used in industries such as water supply and drainage, chemical engineering, and construction, with easy installation that greatly enhances the reliability and safety of pipeline systems.
