mtengo wogulitsa China Petroleum Pipe, Chitoliro Chabwino cha Mafuta, Chitoliro Chobowola Mafuta
Zofuna zathu zamuyaya ndi malingaliro a "msika, kutengera chikhalidwe, sayansi" ndi chiphunzitso cha "khalidwe loyambira, khulupirirani woyamba ndi kasamalidwe kapamwamba" pamtengo wamtengo wapatali China Petroleum Pipe, Chitoliro cha Mafuta, Kubowola Mafuta. Pipe, Tsopano tili ndi gulu la akatswiri pazamalonda apadziko lonse lapansi. Titha kuthetsa vuto lomwe mumakumana nalo. Titha kukupatsirani zinthu zomwe mukufuna. Chonde khalani omasuka kuti mulumikizane nafe.
Kampaniyi imakhazikika mu bizinesi yogulitsa kunja chitoliro chachitsuloChina Drill Pipe, OCTG PIP, Mapaipi amafuta, Chidebe cha mapaipi amafuta, smls mapaipi, W Kuwonjezera pa malonda, ifenso nthawi zonse timayang'anitsitsa kayendedwe ka katundu. Tiye tikambirane za mitundu ya zotengera.
