API 7-1Non-Magnetic Drill Collars for Well Drilling
Iikhola zokubhola zityhubhu ezishinyeneyo ezenziwe ngoomatshini ukusuka kwimivalo yentsimbi eyomeleleyo kwaye zenziwe ngokwemigaqo ukuhlangabezana kunye / okanye ukudlula ukucaciswa kwe-API. Amava ethu ekucacisweni kwezixhobo, iipropathi zoomatshini, unyango lobushushu, umatshini kunye nokuhlola kubonakaliswa ekusebenzeni kwemveliso yethu. Iikhola zeDrill ziza kuyilo olutyibilikayo nolujikelezayo oluneempawu ezongezelelweyo zokusebenza ezikhuselekileyo nezingenazinkathazo.

Udumo lwe-JINBAICHENG ekwenziweni nasekuboneleleni ngezinto zomtya we-Non-Mag drill lusekwe kumava abanzi angaphakathi endlwini zombini kwi-metallurgy kunye nokwenziwa ngokuchanekileyo. I-JINBAICHENG ibisoloko iyinkokeli ekuphuhlisweni kwezinto ezingezizo iMag, iinkqubo ezikhethekileyo zokuvelisa kunye neenkqubo zokuvavanya ezifana nesando sokukroba kunye novavanyo lwendawo eshushu.
