1. Definition:

A jacketed expansion joint comprises an inner expansion joint, an outer expansion joint, a ring plate and a lug plate. This mold using double bellows coaxing structure phase sets in the mezzanine to regulate the flow of heating medium temperature inner bellows built media. A jacketed joint adopting thin wall multilayer structure has good flexibility and enhances its performance.

Without affecting the axial compensation, its structure is based on the use of the jacket with the circulation of heat provided by the heat medium. It is designing to effectively solve the pipeline flow of cooling medium at runtime problem that easily avoid the occurrence of the pipeline where the built in medium streams solidification clogging, and it ensures the orderly production.

2. Advantages of jacketed expansion joint:

The inner expansion joint includes within in order to take over the ends are sealed coaxial bellows and inner pipeline section connected to the inner tube wall corrugated medium along the direction of flow diversion pipe fixed connection. The outer expansion joint includes coaxial ends in order to take over the outer seal connecting the outer bellows and the outer pipeline section. It transverses cross sectional area of the axial through hole for heating medium circulation.

3. Applications of jacketed expansion joint:

A jacketed expansion joint used as heat exchanger is applied to the pipe systems of the petrochemical industry. Medium flow in the petrochemical industry is a liquid state, the media stream process before and after the production process, mainly through pipeline transport. In order to do the project within the transmission medium flow temperature of the tube stable, generally design for casing with thermal design along the pipeline. The model is a jacket structure, without affecting the axial compensation, based on the use of the jacket with the circulation of heat provided by the heat medium to achieve internal compensator built medium heat or warming purposes, effective solve the pipeline flow of the cooling medium at runtime problem is easy to avoid the occurrence of the pipeline where the built in media streams solidification clogging, to ensure the orderly production.
