Chipolopolo chachitsulo cha cholumikiziracho chimafunikanso kuganizira za kuyika kwa nyengo yozizira: mkuwa wopangidwa ndi nickel umapereka chitetezo chokwanira cha dzimbiri komanso mphamvu zamakanika m'malo ambiri akunja, koma m'malo ozizira kwambiri m'mphepete mwa nyanja - Norway fjords, Alaskan m'mphepete mwa nyanja, madoko a Russian Arctic - komwe kupopera mchere kumaphatikizana ndi chitsulo chosapanga dzimbiri chozizira kwambiri (AISI 316) zipolopolo zolumikizira ziyenera kufotokozedwa kuti zisawononge dzimbiri lomwe limachitika pamene mchere umanyowa mobwerezabwereza ndi madzi chifukwa cha kutentha. Mtengo wophatikizana wa jekete la PUR, zisindikizo za silicone, ndi zipolopolo zachitsulo chosapanga dzimbiri ndi pafupifupi 40-60% kuposa ma assemblies wamba a M12 amkati, koma mtengo uwu umaletsa kusweka kwa majekete a PVC, kutayika kwa kukanikiza kotsekedwa kuchokera ku ma gaskets olimba a NBR, komanso dzimbiri lopitirira la zipolopolo zamkuwa zomwe zimapangitsa kuti cholumikizira chisawonongeke msanga m'malo ozizira kwambiri.
