BW HW NW Casing
1. Iityhubhu zethu zeNw Hw Pw Casing zikowona mgangatho uphezulu, zenziwa ukuba zibe neenkcukacha ezichanekileyo kusetyenziswa iteknoloji yokuqhubela phambili.
2. Zenziwa kwi-tube yensimbi engenamthungo ngokutsalwa ngokubanda.Izinto eziphathekayo ziyi-XJY850 / 30CrMnSiA ehlangabezana nomgangatho wehlabathi.
3. Iinduku ze-drill zenziwe kwizinto ezisemgangathweni zokushisa ukushisa eziqinisekisa amandla aphezulu, ukuxhatshazwa kokugqoka kunye nokuqina kwizicelo ezinzima kakhulu.
4. Iinduku kunye ne-casing zenziwe phantsi kwemigangatho yoshishino olungqongqo, kwaye intsimi ivavanywa phantsi kweemeko ezahlukeneyo.
5. Zonke iintonga ziyilelwe ukuba zihambelane nezinye iintonga ezenziwe kumgangatho weDCDMA.
