Incazelo
I-S Pipe Ram isetshenziselwa i-Ram Blow Out Preventer eyodwa noma kabili (BOP). Usayizi wenqama uhambisana ne-OD yepayipi. Ingavalwa phakathi kwesiqu sepayipi kanye nendawo ye-annular kahle. Ngokungeziwe emininingwaneni eshiwo, uhlobo lwe-S Pipe Ram lusebenza njengengxenye ebalulekile kumhlangano owodwa noma kabili weRam Blow Out Preventer (BOP). Idizayini yayo eyingqayizivele, eklanyelwe ngokukhethekile ukufanisa ububanzi bangaphandle bepayipi, iqinisekisa uphawu olusebenzayo noluqinile, okusiza ukugcina ubuqotho be-wellbore phakathi nezimo zokucindezela okuphezulu.
Uhlobo lwe-S Pipe Ram lwenziwe ngenhlanganisela yokuqina nokunemba. Yakhiwe kusetshenziswa izinto ezisezingeni eliphezulu ezingamelana nezimo ezinzima zokumba, ezithuthukisa ukuphila kwayo isikhathi eside nokwethembeka. Idizayini yalo mhlangano wenqama ifinyelela ibhalansi phakathi kokuqina nokuvumelana nezimo, okuvumela uphawu olufanele ezimweni ezihlukahlukene zokusebenza.
Isici esivelele sohlobo lwe-S Pipe Ram yikhono layo lokwakha uphawu oluvikelekile phakathi kwesiqu sepayipi kanye nesikhala se-annular somthombo. Lokhu kusebenza kuqinisekisa ukuqukatha okusebenzayo koketshezi lokumba, kuvimbele ukuchitheka kanye nokuba negalelo emikhubeni ephephile yokulawula umthombo.
Ukusebenziseka kalula kokufakwa nokugcinwa kahle kuyizici ezibalulekile zalo mhlangano wenqama, okunciphisa isikhathi sokuphumula kanye nezindleko zokusebenza. Ukuhlanganiswa kohlobo lwe-S Pipe Ram kumhlangano we-BOP akudingi ukuguqulwa okuphawulekayo, okuthuthukisa ukusebenza kwayo emisebenzini ehlukahlukene yokumba.
Ngaphezu kwalokho, ukuguquguquka kohlobo lwe-S Pipe Ram kuyenza ivumelane nohlu olubanzi losayizi wamapayipi, ivumelane nezidingo zokumba ezihlukene. Idizayini yayo iwukubonakaliswa kokuzibophezela kukhwalithi, ukusebenza, nokuphepha, okuyenza ibe ithuluzi elibalulekile lokulawula kahle kahle.
