Selecting a corrugated metal hose by characteristics of bellow
Made of stainless steel bellow is pressure bearing part of corrugated metal hose. It provides base characteristics of high-pressure corrugated metal hose – tightness, resistance and reliability. VZM offers as standard bellows that meet the majority of requirements as special modifications.Send us all known parameters (working pressure, bend radiuses, temperature and others) to select a corrugated metal hose with optimal bellow for your operation conditions. Characteristics of some types of bellows are also shown on our website (go to the Tables below).
