Muaj ob hom corrugated kav siv nyob rau hauv stainless hlau hoses, ib tug yog ib tug kauv corrugated yeeb nkab thiab lwm yam yog ib tug annular corrugated yeeb nkab. Kauv corrugated yeeb nkab yog ib lub plhaub tubular nrog corrugations teem nyob rau hauv ib tug kauv zoo. Muaj lub kaum sab xis ntawm ob lub corrugations uas nyob ib sab, thiab tag nrho cov corrugations tuaj yeem txuas tau los ntawm txoj kab helical. Lub annular bellows yog ib tug tubular plhaub nrog kaw annular corrugations, thiab cov nthwv dej yog tsim los ntawm series ntawm annular corrugations. Lub annular corrugated yeeb nkab yog tsim los ntawm seamless yeeb nkab los yog welded yeeb nkab. Kev txwv los ntawm txoj kev ua, qhov ntev ntawm ib lub raj feem ntau yog luv dua li ntawm cov kauv corrugated raj. Qhov zoo ntawm annular bellows yog zoo elasticity thiab tsis tshua muaj zog.
