Gore idzva rinounza mavambo matsva. Tianjin Zhengneng Pipe Indasitiri Co, Ltd inyanzvi bhizinesi rinobatanidza kugadzirwa kwepombi, kutengesa uye kutumira kunze. Zvigadzirwa zvikuru zvekambani iyi zvinosanganisira maboiler pombi, pombi dzefetereza, pombi dzepetroleum nemapombi akaumbwa.
Zhengneng Pipe Indasitiri yakazvipira kupa purojekiti yakavimbika uye yakakosha uye mhinduro dzekushanda kune vatengi uye vanobatika pasirese, kusanganisira indasitiri yeboiler, indasitiri yemafuta negasi, kuchengetedza mvura, migodhi, indasitiri yesimba uye indasitiri yemidziyo yemagetsi. Zvigadzirwa zvinotengeswa kuSoutheast Asia, Middle East, North America neSouth America.
Nhasi tichazivisa zvigadzirwa zvikuru zvekambani yedu. Zvigadzirwa zvekambani yedu ndezvi: Boiler Pipes account ye40%; mapaipi emutsetse anotora 30%; Petrochemical pipes inotora 10%; heat exchanger tubes account ye10%; Mechanical pombi dzinoita 10%.
