The rubber flexible joints, made up of Inner rubber layer and fabric reinforcement layer (reinforcement layer has multiple layers of scraped nylon cord fabric), middle rubber layer, outer rubber layer and end reinforcement metal ring or wire ring, is vulcanized by high temperature and high pressure. It can match with with metal flange or parallel joint loosening sleeve when working.

According to performance, it can be divided into three main categories: general, special and heat resistant.

1. General type: it is suitable for water from -15°-80°C and Acid solution or alkali solution concentration below 10%.

2. Special type: Suitable for special performance requirements, such as oil resistance, plug resistance, ozone resistance, wear resistance and good chemical corrosion resistance.

3. Heat resistant type: suitable for carrying single ball rubber joints and water at temperature above 80°C.

According to the connecting way between products and pipes, it can be divided into three categories: loose flange, fixed flange and threaded flange.

According to the structure, it can be roughly divided into five types: single sphere, double sphere, different diameter sphere, curved sphere, and air pressure coil. In addition, different diameter sphere can be divided into concentric equal diameter, concentric different diameter and eccentric different diameter.

In industrial pipelines, the rubber quality will directly affect the long-term use of rubber flexible joints in pipelines. Under repeated working conditions, rubber molecular chain breaks to form free Tsuen. If not replaced in time, the rubber soft joints will cause joints physical expansion in a short time under the pipe pressure (such as Pipeline vibration, pipeline inside pressure too large). Once a slight crack appears on the surface of the rubber soft joint, it will gradually expand and cause fracture. Therefore, in order to overhaul more conveniently, the joint surface is forbidden to paint and wind thermal insulation material.
