China Short Drill tubbada warshadaynta
Sharaxaad:
Hardbanding: Kala-goysyada qalabka iyo mararka qaarkood jirka tuubada daloolka gaaban waa la adkeyn karaa si ay u kordhiso caabbinta xirashada iyo daxalka.
Xidhiidhada Dhamaadka: Xidhiidhada dhamaadka waa isku xidhka API ee u oggolaanaya in tuubada lagu daro qaybaha kale ee xadhigga laydhka.
Darajada: Darajada tuubada daloolista gaaban waxa ay tilmaamaysaa xoogga iyo cimriga tuubada. Darajada waxaa inta badan lagu go'aamiyaa xoogga wax-soo-saarka walxaha.
Sharaxaad:
Tuubbada qodista gaaban waa qalab lagu hagaajinayo dhererka u dhexeeya qalabka qodista si loo gaaro ujeedo farsamo oo gaar ah oo ku saabsan habka qodista. Marka loo eego qaabka garabka, waxay u qaybsan tahay qaab-dhismeedka garabka ee jilicsan iyo qaab-dhismeedka garabka toosan.
Alaabooyinka taxanaha ah ee dhuumaha daloolista gaaban ayaa inta badan loo isticmaalaa si ay ugu habboonaato isticmaalayaasha goobta saliidda leh ee tiirarka tuubada daloolista. Laga sameeyay birta qaab dhismeedka daawaynta xoogga badan ka dib daaweynta kulaylka, waxqabadka farsamada, iyo dunta wadajirka ah waxay waafaqsan yihiin shuruudaha API.
