Qaybaha ilkaha ee birta ah ee saliidda API IADC217 8.5 inji (215mm) oo loogu talagalay qodista dhagaxa

Isticmaalka bit Tricone oo leh xarig joornaal ah, dusha sare ee madaxa oo adag., oo leh qaab koone ah oo lagu dahaadhay dahaarka yareeya is jiidjiidka ka dibna lagu dahaadhay qalin. Awoodda culayska iyo iska caabbinta qabsashada ee garabka ayaa si weyn loo hagaajiyay.
Shaabadda O-ring waxay ka samaysan tahay bunni cufan oo aad u adkaysi badan oo leh qaybta shaabadda oo kordhay iyo flange shaabadaysan oo si sax ah loogu talagalay aagga shaabadda koonaha ayaa kordhisay kalsoonida shaabadda. Qalabka qabsashada ayaa kubbad lagu xiri karaa.
Birta ilkaha, dusha sare ee ilkaha waxaa lagu dhejiyaa nooc cusub oo iska caabiya xirashada.
Maaddada iyo sidaas darteed cimriga shaqada ee qaab-dhismeedka jarista iyadoo weli la ilaalinayo ROP sare
----- Qaab-dhismeedka Jarida
Ilkaha Birta ah: Kaarboohaydrayt tungsten ah oo tayo sare leh oo si adag u wajahaya dusha sare, waxay si weyn u xoojisaa iska caabbinta xirashada ilkaha.
Gelinta Tungsten Carbide: Noocyo kala duwan oo gashado carbide tungsten tayo sare leh ayaa lagu qalabayn karaa bits-ka, xirfadlayaal iyo
Xulashada cilmiyeed ee gelinta sida waafaqsan codsiyada kala duwan iyo habka qodista si loo gaaro qodis hufan oo heer sare ah
