High quality limit type expansion joint
The limiting device for limit type expansion joint shall be reasonably matched with the flexible rubber joint, which can limit the positioning displacement when used in the general connection of pipelines or in the pipeline with displacement requirements. When the flexible rubber joint is connected with pumps and valves, the limiting device shall be equipped on the flexible rubber joint to transfer force, It is an ideal substitute for steel force transmission joint.
Performance characteristics of limit type expansion joint
1. It has the advantages of small volume, light weight, good ductility, convenient installation and maintenance, etc.
2. Horizontal, radial and angular deviation can be caused during installation, which will not be limited by the uneven center of pipe plug and flange surface.
3. When working, it can reduce the transmission noise of the structure and has strong damping capacity.

Note:To select the proper piping limit type expansion joint , it is critical to understand the media compatibility with the materials selected, full temperature, pressure and vacuum ranges, movements required, and dimensions between pipe flanges. With this information, JINGNING application engineers can assist in determining the ideal expansion joint for any application.
Limit flexible rubber joint production flow
Do you know how is a high quality limit flexible rubber joint made?Let's see with JINGNING.
Limit type expansion joint advantage
1. The spherical structure has strong internal pressure stability, and combined with strong special reinforced nylon, it has excellent pressure resistance
2. Excellent shock absorption and noise reduction performance. Reduce the inherent vibration, noise and movement of the pipeline system, enable the isolation equipment to move freely, and eliminate the vibration and repulsive sound common in metal joints.
3. Compensate for greater elongation, compression, lateral and angular movement.
Limit type expansion joint application
Because the rubber joint has good comprehensive performance, it is widely used in chemical industry, construction, water supply, drainage, petroleum, light and light industry, refrigeration, sanitation, plumbing, fire protection, electric power and other basic industries.
