Double Ball Rubber Expansion Joint

Flexible Protection for Piping Systems: The Antioxidant and Efficient Solutions of Carbon Steel Double Ball Rubber Expansion Joints​The Carbon Steel Double Ball Rubber Expansion Joint Antioxidant is crafted from premium synthetic rubber, boasting exceptional chemical molecular stability, antioxidant, ozone-resistant, aging-resistant, and dust-resistant qualities, ensuring a prolonged service life. Its inner wall features a smooth cylindrical surface lined with polyester cord, while the external protrusion incorporates a steel wire support ring. The inner layer is composed of media-resistant rubber, and the outer layer is standard rubber. This design primarily prevents collapse under negative pressure and withstands short-term internal pressure, mitigating swings at the lower end of the suction pipe caused by pump power and suction vibration.​The double sphere rubber joint ensures uniform water flow and reduces pump power consumption. Furthermore, the absence of grooves in the vertical…
