Expansion joints(compensators)
Expansion joints are flexible connectors used in piping systems to absorb thermal expansion, vibration, and movement while maintaining structural integrity. They are commonly made of materials like rubber, metal bellows, or fabric. Expansion joints allow for axial, lateral, and angular movements in pipelines, compensating for changes in temperature, pressure, and external forces. These components are crucial for preventing stress on pipes, equipment, and support structures, thus enhancing system longevity and reliability. Expansion joints find applications in various industries, including HVAC, petrochemical, power generation, and marine.
| Main Item | Classification | Description |
| Metal Expansion Joint | Elbow Expansion Joint | Bend the pipe into a U-shaped or other shape, also known as tension bends,are a type of expansion joint that utilizes the elastic deformation ability of the form to compensate. Its advantages are good strength, long service life, and on-site production.The disadvantages are space-consuming, high steel consumption, and high friction resistance. This type of expansion joint is widely used in various steam piping and long pipes. |
| Bellows Expansion Joint
| A bellows expansion joint is a metal component that allows pipelines to expand and contract axially, with some flexibility for bending. To prevent overextension, protective rods or rings are installed at each end, and guide supports are added along the pipelines. Angular and lateral expansion joints can also compensate for rotational and lateral deformations. While these joints save space and materials and can be easily standardized and mass-produced, they have a shorter lifespan. They're typically used in short pipelines with low temperature and pressure. As bellows production improves, they're becoming more versatile, now suitable for pipe systems with pressures up to 6.0 MPa. | |
| Slip-Type Expansion Joint | The slip-type expansion joint features inner and outer sleeves allowing axial movement, sealed with a stuffing box to maintain alignment. It comprises sleeves, shells, and sealing materials, primarily used for compensating axial expansion and rotation in pipelines at any angle. With a compact design and significant compensation capability, it's ideal for hot water, steam, and grease media. By sliding the sleeve against the outer one, it accommodates thermal expansion. Equipped with a high-performance self-sealing dynamic seal, the inner sleeve seamlessly slides within the shell, ensuring effective sealing for any pipeline. Enhanced with synthetic materials, the seal withstands high temperatures, corrosion, and aging, with an applicable temperature range of -40 to 150 degrees Celsius, extendable to 350 degrees Celsius in specialized conditions. It ensures axial sliding and prevents leakage, offering comprehensive functionality for pipeline applications. | |
| Non-metallic Expansion Joint | Rubber Expansion Joint | Composed of rubber and rubber-fiber composite materials, steel flanges, sleeves, and insulation materials, it is mainly used for flexible connections between various fans and ducts. Its functions include shock absorption, noise reduction, sealing, medium resistance, easy displacement and installation. It is an ideal accessory for shock absorption, noise reduction, smoke and dust removal in the field of environmental protection. |
| Fabric Expansion Joint | The fabric expansion joint is mainly made of fiber fabric, rubber, and other high temperature resistant materials. It can compensate for the vibration and deformation of fans and ducts.Fabric expansion joints can compensate for axial, lateral, and angular products, with features such as no thrust, simplified support design, corrosion resistance, high temperature resistance, noise reduction, vibration reduction,and others.It is particularly suitable for hot blast pipes and smoke and dust pipeline of power plant.The non-metallic compensator's fiber fabric and insulation cotton itself have the functions of sound absorption and vibration isolation, therefore they can effectively reducing the noise and vibration of boiler, fan, and other systems. Simple structure, light weight, and easy maintenance. |
