| High Light | Limit Rod Single Sphere Joint ，Large Diameter NBR Flange Joint ，Chemical Resistant Restrained Joint | ||
The Liwei Limit Rod Single Sphere Flexible Rubber Expansion Joint is a large diameter restrained compensator fitted with a limit rod / limit device that controls axial displacement and prevents pipe pull-out. Built with an NBR (nitrile) rubber body, it offers strong oil resistance and chemical resistance for large bore pipelines. The limit device keeps the single sphere body within its safe movement range while still absorbing vibration, noise and thermal movement. With multi-standard DIN / ANSI / JIS flanges and a DN25 to DN4000 range, it is a durable and leak-free solution for large diameter water, oil and chemical lines.
