Chaka chatsopano chimabweretsa chiyambi chatsopano. Tianjin Zhengneng Pipe Viwanda Co., Ltd. ndi akatswiri ophatikizira kupanga mapaipi, kugulitsa ndi kutumiza kunja. Zogulitsa zazikulu za kampaniyi ndi mapaipi a boiler, mapaipi a feteleza, mapaipi amafuta ndi mapaipi apangidwe.
Zhengneng Pipe Industry yadzipereka kupereka ntchito yodalirika komanso yofunikira komanso mayankho ogwira ntchito kwa makasitomala ndi othandizana nawo padziko lonse lapansi, kuphatikiza makampani opangira boiler, mafakitale amafuta ndi gasi, kusunga madzi, migodi, mafakitale amagetsi ndi zida zamakina. Zogulitsa zimagulitsidwa ku Southeast Asia, Middle East, North America ndi South America.
Lero tiwonetsa zinthu zazikulu za kampani yathu. Zogulitsa zazikulu za kampani yathu ndi: Mapaipi a Boiler amawerengera 40%; mapaipi a mzere amawerengera 30%; Mapaipi a petrochemical amawerengera 10%; machubu osinthira kutentha amakhala 10%; Mipope yamakina imakhala ndi 10%.
