Sentry Ram BOP
Āhuahira
Ko ta matou Sentry RAM BOP he pai mo nga riu whenua me nga riu hiko. He pai ake i roto i te ngawari me te haumaru, te mahi i raro i te wera nui ki te 176 °C me te tutuki i te API 16A, 4th Ed. PR2 paerewa. Ka whakahekehia nga utu mana ma te ~ 30% me te whakarato i te kaha kutikuti teitei i roto i tana akomanga. Kei te waatea ano te Hydril RAM BOP mo nga Jackups me nga riipene Platform i te 13 5/8” (5K) me te 13 5/8” (10K).
Ko te Sentry BOP he whakakotahi i te ngawari o te tiaki, te ngawari o te whakahaere, me te utu iti e tika ana kia whakataetae i te maakete whenua o enei ra. He poto ake, he mama ake i era atu 13 in. drilling ram blowout preventers , ko te hoahoa Sentry te pupuri i te kaha me te pono mo te Hydril Pressure Control BOPs kua mohiotia mo nga tau 40+ kua hipa. Ka taea te whakarite i nga huihuinga ki te whakatutuki i nga hiahia o te kaiwhakamahi me:
1. Kotahi, takirua ranei te tinana
2. Kaimahi takitahi, tandem ranei
3. Poraka hipi kutikuti matapo
4. Nga poraka hipi paipa kua whakaritea
5. Poraka hipi taurangi
6. 5,000 psi me 10,000 psi putanga
Āhuatanga:
Ko te BOP he mea hanga motuhake me te whakawhanake mo nga mahi Mahi Mahi.
I raro i te ahua o te diameter rite, ka taea e te mahi mahi te makona i te tohu pehanga o te bop anake ma te whakakapi i te diameter hono hono me te huihuinga kuaha.
Ko te aratau whakaurunga o te kuaha he taha-tuwhera, na reira he pai ki te whakakapi i te huihuinga kuaha.
