Beschreibung
Zusammenfassung:	FIELD: pipeline transport. ^ SUBSTANCE: multilayer bellows compensator comprises several layers of corrugated shells whose end sections are welded to the load-bearing rings. The thickness of the internal layer of the bellows which is in a contact with the oxidizing high-temperature and high-pressure fluid exceeds the thickness of the other layers of the bellows by a factor of 2-3. The internal layer of the bellows is made of the chrome-nickel alloy that comprises at least 70% of nickel. The other layers are made of stainless steel. ^ EFFECT: enhanced reliability. ^ 1 cl, 1 dwg
