The Double Ball Rubber Expansion Joint consists of two rubber balls connected by precision technology
Connected to pumps, valves,
Fire-fighting equipment is mainly used for fire fighting, water supply and drainage engineering,
chemical and petroleum pipelines, high-vibration pipelines, pipelines with frequent temperature changes;
It mainly plays the role of a shock absorber, allowing the pipe to expand and contract freely and protect safety
The operation of pipelines during production.
