The flange type loose sleeve expansion joint is mainly used for vibration isolation and noise reduction and displacement compensation

Flange loose sleeve Expansion joint It is mainly suitable for vibration isolation, noise reduction and displacement compensation. The rubber flexible joint ball is composed of a rubber tube with a reinforced layer of multi-layer scraping nylon cord fabric, an inner rubber layer and an outer rubber layer. When rubber flexible joint is used in high-rise water supply, the pipeline must have fixed support or fixed bracket, and the force of fixed support or bracket must be greater than the axial force. According to the different media, the rubber materials used are also different, which have the functions of acid resistance, alkali resistance, heat resistance, corrosion resistance, wear resistance, oil resistance and so on. It is a kind of pipe joint with high elasticity, high air tightness, medium resistance and weather resistance.

The functional characteristics of the flange type loose sleeve expansion joint are: light weight, good elasticity, small volume, convenient installation and maintenance; axial, horizontal and angular displacement can be generated during installation, which is not limited by the pipe out of center and flange is not parallel; it can reduce the structure transmission noise and has strong vibration absorption capacity. According to the different materials, it can be made into various varieties, such as alkali resistance, acid resistance, oil resistance, corrosion resistance, heat resistance, and so on. It can adapt to a variety of media and environment connection methods: generally, there are flange connection, screw thread connection, clamp connection, etc.

Flange type loose sleeve expansion joint has good comprehensive function because of rubber flexible joint. Rubber flexible joint is composed of fabric reinforced rubber parts, flat flexible joint, loose metal flange or threaded pipe flange, which is used for pipe vibration isolation, noise reduction and displacement compensation.

Shanghai Huanjing is engaged in R & D of expansion joint, loose sleeve expansion joint, flange loose sleeve expansion joint and other expansion joints. The flange type loose sleeve expansion joint is mainly used for vibration isolation and noise reduction. The rubber flexible joint ball is composed of a rubber tube with a reinforced layer of multi-layer scraping nylon cord fabric, an inner rubber layer and an outer rubber layer. When rubber flexible joint is used in high-rise water supply, the pipeline must have fixed support or fixed bracket, and the force of fixed support or bracket must be greater than the axial force.
