Metal Compensator/Metal Soft Joint

The role of metal compensators

Metal compensators are an important pipeline compensation element, and their main functions include:

 Compensation for displacement: used to compensate for the mutual displacement of the connection ends of pipelines, machines and equipment.

 Absorb vibration: reduce installation stress and absorb vibration generated when the pump is running.

 Damping and silencing: play a damping and silencing role when conveying gas and liquid media (such as hot water, steam, crude oil, etc.).

Application scenarios

 Iron and steel industry: application in large blast furnaces, hot blast furnaces and other equipment to compensate for pipeline displacement and reduce installation stress.

 Pumps and valves: as pump hoses, compensate for the thermal expansion of pipelines and reduce the thrust of thermal expansion on pumps.

 Tank inlet and outlet pipelines: compensate for displacement, absorb axial displacement caused by thermal expansion of pipelines and lateral displacement caused by sinking of tank foundations.

 Connection between equipment: compensate for thermal expansion of pipelines between equipment, make installation more convenient, and change the stress condition of equipment.

Common types

 Bend pipe compensator: uses the elastic deformation ability of the shape for compensation. The advantages are good strength and long life. The disadvantages are large space occupation and high steel consumption.

 Bellows compensator: It can expand and contract along the axis of the pipeline, and also allows a small amount of bending, which is used for axial length compensation.

 Sleeve compensator: It consists of inner and outer sleeves that can make axial relative movement.

Each has its own characteristics

 Bend pipe compensator: It is widely used in various steam pipes and long pipes.

 Bellows compensator: The advantages are saving space, saving materials, facilitating standardization and mass production, and the disadvantage is a short life.

 Sleeve compensator: It is suitable for pipes with low temperature and pressure and short length.

Application in the steel industry

In the steel industry, metal compensators are widely used in large blast furnaces, hot blast furnaces and other equipment, especially in pressure supply and exhaust pipe systems, cooling pipe systems, air supply pipes, oxygen supply pipes, cooling water pipes, etc., which can not only compensate for the displacement of the pipe, but also reduce the generation of installation stress.

Application in pumps and valves

As a pump hose, the metal compensator can compensate for the thermal expansion of the pipe, reduce the thrust of the thermal expansion on the pump, or absorb the vibration generated when the pump is running, thereby improving the working efficiency of the pump and extending its service life.

Application of inlet and outlet pipes of storage tanks

Installed in the inlet and outlet pipes of storage tanks, metal compensators can not only compensate for displacement, but also absorb axial displacement caused by thermal expansion of pipelines, and compensate for lateral displacement caused by sinking of tank foundations, which can not only prevent damage to pipelines and tank walls, but also have a certain anti-seismic effect.

Application of connections between equipment

The connection between equipment can compensate for the thermal expansion of pipelines between equipment, making installation more convenient, changing the stress condition of equipment, and making installation easier. These are important functions of metal compensators in the fields of steel, pumps and valves, and petroleum.

In summary, metal compensators play an indispensable role in modern industry, and their diverse types and wide range of application scenarios make them an indispensable and important component in pipeline systems.
