API 7-1Non-Magnetic Drill Collars for Well Drilling
Drill makora akakora-madziro tubulars akagadzirwa kubva kusimbi simbi mbariro uye akagadzirwa kune zvakatemwa kusangana uye / kana kudarika API zvakatemwa.Chiitiko chedu mukugadzirwa kwezvinhu, michina zvivakwa, kurapwa kwekupisa, machining uye kuongorora zvinoratidzwa mukuita kwedu kwechigadzirwa.Drill makora anouya mune anotsvedza uye anotenderera madhizaini ane mamwe maficha ekuchengetedzeka uye asinganetse mashandiro.
