These corrugated membrane bellows find their application in: machine construction, vacuum technology, aviation and space engineering, medical technology, construction of special fittings, sealing element construction, as floating ring seals in pumps and compressors and as volume compensation bodies in oil-cooled high voltage insulators.A range of metal hoses, expansion joints, metal hose expansion joints, double-walled welded metal hoses and expansion joints, metal bellows and multiply axial expansion joints are provided by thethe company, and its daughter concern, company, and its daughter concern, witzenmann india, offers a range of metal hoses, expansion joints, metal hose expansion joints, double-walled welded metal hoses and expansion joints, metal bellows and multiply axial expansion joints witzenmann gmbh . These expansion joints find their applications for use in the chemicals industry and production plants. Corrugated membrane bellows provide a very high degree of elasticity, low spring rates, lows hysteresis and high bend fatigue strength or service life. They are especially suitable for components under low pressure or a vacuum. The expansion capacity of up to 80% of its construction length ensures maximum movement capacity. Apacity. Areas of application: machine construction, vacuum technology, aviation and space engineering, medical technology, construction of special fittings, sealing element construction, as floating ring seals in pumps and compressors and as volume compensation bodies in oil-cooled high voltage insulators.
