The metal corrugated compensator is a kind of compensator. The metal corrugated compensator is made of austenitic stainless steel or materials according to user requirements. It has excellent flexibility, corrosion resistance and high temperature resistance (-235℃ ~ +450℃ ), high pressure resistance (up to 32MPa), can be connected in any direction in the pipeline to compensate for temperature and absorb vibration, reduce noise, change the direction of medium transport, eliminate mechanical displacement between pipelines or between pipelines and equipment, etc. The double flange metal corrugated hose is especially suitable for flexible joints of various pumps and valves with displacement and vibration.

The metal corrugated compensator chooses different metal materials for different purposes. Because of their different materials, the performance and use of the processed metal bellows are also different.

There are two types of corrugated pipes used in metal corrugated compensators, one is a spiral corrugated pipe, and the other is an annular corrugated compensator.

Spiral metal corrugated compensator

The spiral metal corrugated pipe is a tubular shell with corrugations arranged in a spiral shape. There is a spiral rise angle between two adjacent corrugations, and all the corrugations can be connected by a spiral line.

Ring metal corrugated compensator

The ring-shaped metal corrugated compensator is a tube-shaped shell with the corrugation in a closed circular ring shape, and the waves are formed by the series of circular corrugations. The annular corrugated pipe is formed by seamless pipe or welded pipe. Restricted by the processing method, the length of a single tube is usually shorter than that of a spiral corrugated tube. The advantages of the annular bellows are good elasticity and low rigidity.

The metal corrugated compensator is installed in the liquid conveying system as a kind of flexible pressure-resistant pipe to compensate for the mutual displacement of the connecting ends of pipelines or machines and equipment, absorb vibration energy, and can play the role of vibration reduction and noise reduction. It has good flexibility and quality Light weight, corrosion resistance, fatigue resistance, and high and low temperature resistance.

Metal bellows, as sensitive components, damping components, compensation components, sealing components, valve components and pipeline connectors, are widely used in automatic control and measuring instruments, vacuum technology, machinery industry, power industry, transportation and atomic energy industry. .

Metal bellows choose different metal materials due to their different uses. Because of their different materials, the performance and use of the processed metal bellows are also different.
