Product Description
Pipework expansion bellows is a type of pipeline joint with high elasticity, high gas tightness, medium resistance, and weather resistance. It is mainly composed of inner and outer layers of rubber, curtain layers, and steel wire rings to form a tubular rubber component, which is vulcanized and then combined with metal flanges or parallel joints to form a loose sleeve. Each part has its specific function and function, together forming the unique structure of rubber joints.
Performance characteristics of rubber joints:
Pipework expansion bellows are widely used in various fields, including construction, chemical industry, shipbuilding, tap water, gas, chemical pipelines, petroleum pipelines, food pipelines, air conditioning pipelines, and sewage treatment.
