Umwaka mushya uzana intangiriro nshya. Tianjin Zhengneng Pipe Industry Co., Ltd. ni uruganda rwumwuga ruhuza umusaruro, kugurisha no kohereza hanze. Ibicuruzwa nyamukuru by’isosiyete birimo imiyoboro itekesha, imiyoboro y’ifumbire, imiyoboro ya peteroli hamwe n’imiyoboro yubatswe.
Inganda za Zhengneng ziyemeje gutanga umushinga wizewe kandi ufite agaciro nigisubizo cyibikorwa kubakiriya nabafatanyabikorwa kwisi yose, harimo inganda zikora amashyiga, inganda za peteroli na gaze, kubungabunga amazi, ubucukuzi bwamabuye y'agaciro, inganda ninganda zikoreshwa mubukanishi. Ibicuruzwa bigurishwa mu majyepfo yuburasirazuba bwa Aziya, Uburasirazuba bwo hagati, Amerika ya Ruguru na Amerika yepfo.
Uyu munsi tuzamenyekanisha ibicuruzwa byingenzi byikigo cyacu. Ibicuruzwa byingenzi byikigo cyacu ni: Imiyoboro ya Boiler ihwanye na 40%; imiyoboro y'umurongo igera kuri 30%; Imiyoboro ya peteroli ifite 10%; imiyoboro ihindura ubushyuhe igera kuri 10%; Imiyoboro ya mashini ihwanye na 10%.
