The Difference Between Spiral and Annular Metal Bellows
The ring-shaped metal bellows is a tube-shaped shell with a corrugated ring, and the waves are formed by a series of ring-shaped corrugations. The ring-shaped metal 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 metal bellows. The advantages of the ring-shaped metal bellows are good elasticity and low rigidity. The ring-shaped metal bellows is a hydraulic forming process.
Spiral metal bellows is a tube-shaped shell with corrugations arranged in a spiral shape. There is a spiral angle between two adjacent corrugations. All metal corrugations can be connected by a spiral line. Spiral metal bellows is a hydraulic extrusion molding process.
Metal hose is a high-quality flexible pipe in modern industrial piping. It is composed of metal bellows, metal mesh sleeves and joints. Its inner tube is a thin-walled metal corrugated tube with a spiral or circular wave shape, and the outer mesh sheath of the metal corrugated tube is woven from stainless steel wire or steel belt according to certain parameters. It is suitable for pipelines that need to be sufficiently flexible to prevent vibration in piping. It is also suitable for steam, coal gas, air, heavy oil, petroleum, chemical drugs, etc.
Labideal is a professional research, development and production of vacuum hoses, vacuum bellows, metal bellows , Metal hose, stainless steel bellows, flange metal hose, metal corrugated compensator, metal compensator, corrugated compensator, stainless steel compensator. It can manufacture four types of metal compensators for axial type, horizontal type, angular type and hot air pipeline for working pressure 0.1-6.0MPa, temperature range -200-1300 ℃, nominal diameter DN6-1000mm. At the same time, our company can also develop other types and uses of corrugated compensators for users according to the user’s working environment, conditions and fatigue damage times.
