Profile: Wenzhou Dosen Bellows Factory focuses on corrugated tube, compensator, metal bellows, expansion joints and metal hose. Our products are applicable in metallurgy, chemistry and industry, oil, convenient, architecture and ship of making. Our expansion joints of corrugated compensator metal bellows take metal bellows as flexible parts and they are the structural components for displacement compensation, reducing distortions and vibrations in piping transmission systems, as they have the features such as anti-fatigue, anti-pressure, being highly resistant to high & low temperature. Our stainless steel bellows compensator is damping and is used in central air-conditioning pumps, fire pumps and water pumps. Our thin-walled corrugated metal pipe with stainless steel pipe for waveform processing is flexible and good temperature, pressure performance & applied in various industrial gases and water, oils, medicines & other fluid medium of transmission.
