Introduction: Because of its flexibility, the corrugated compensator can compensate the temperature difference deformation or other deformation between the equipment and the pipeline, and can prevent and reduce the thrust of the pipeline to the equipment and adapt to the uneven settlement of the oil tank foundation.

Ripple Compensator Because of its flexibility, it can compensate for the temperature difference and other deformation between the equipment and the pipeline, and can prevent and reduce vibration, reduce the thrust of the pipeline on the equipment and adapt to the uneven settlement of the oil tank foundation. Because it is sealed, it can be widely used in chemical industry, oil refining, electric power, light industry, atomic energy, metallurgy, machinery, etc. Because the power pipeline and heat pipe are widely used in the industrial and civil sectors, the demand for compensator is very large. In recent years, many large and medium-sized cities are building a large number of residential buildings. In order to save energy and eliminate environmental pollution, we should vigorously promote central heating and urban heating, which are inseparable from thermal pipelines.

    Corrugated compensator The metallurgical sector, the petrochemical sector, and the urban construction sector. Due to the change of customer demand, the market trend of corrugated compensator products will also change accordingly. In the future, the main development trends are as follows:

1. With the transfer of oil development to inland and offshore oilfields, and the development of power industry from thermal power below 300000 kW to thermal power, hydropower and nuclear power above 300000 kW, the performance and parameters of corrugated valve products should be changed accordingly according to the change of equipment application field;

2. A large number of low-pressure corrugated pipe valves are generally used in urban construction system, and they are developing into environmental protection and energy-saving types, that is, the transition from the low-pressure iron gate valve used in the past to the environmental protection type of rubber plate valve, balance valve, metal seal butterfly valve and middle line sealing butterfly valve, and the oil and gas transmission engineering is developing towards pipeline, which requires a large number of flat gate valves and ball valves;

3. The other side of energy development is energy saving, so from the aspect of energy saving, steam trap should be developed, and high parameters of subcritical and supercritical should be developed;

4. The construction of the power station is developing to a large scale, so it needs large diameter and high pressure safety valve and pressure relief valve, and also needs quick opening and closing of bellows valve;

5. According to the needs of the whole project, the supply of bellows valve has developed from single variety to multi variety and multi specification. It is more and more important for a project to supply all bellows valves from one manufacturer.
