·Lawula ingcindezi ukuze uvimbele ukuchichima nokuqhunyiswa.
·Yehlisa ingcindezi ye-wellhead casing ngokusebenza kwe-valve yokuklinywa.
·Insimbi egcwele futhi enezinhlangothi ezimbili
·Ingaphakathi lokuklinywa lakhiwe nge-hard alloy, ekhombisa izinga eliphezulu lokumelana nokuguguleka nokugqwala.
·I-valve yokusiza isiza ukunciphisa ukucindezela kwe-casing nokuvikela i-BOP.
·Uhlobo lokucushwa: iphiko elilodwa, iphiko elikabili, iphiko elinamaphiko amaningi noma elikhuphukela phezulu
·Uhlobo lokulawula: manual, hydraulic, RTU
Bulala Okuningi
·Ukubulala okuningi kusetshenziselwa ukubulala kahle, ukuvikela umlilo kanye nokusiza ekuqothulweni komlilo.
