It is suitable for the installation and use of pumps, drainage pipes, water towers, water meters and valves, and plays a regulating role in the temperature difference expansion of pipelines; Widely used in metallurgy, electric power, chemical industry, water supply and drainage and sewage treatment and other industries.
The limit expansion joint is an improved version of the loose sleeve expansion joint, which is secured with double nuts when it reaches its maximum expansion. This allows the pipeline to expand within a safe range and acts as a limit when it exceeds its maximum capacity, ensuring the pipeline's safe operation. It is particularly suitable for vibrating or inclined pipelines, as well as turning connections.
