Hāʻawi ka makahiki hou i kahi hoʻomaka hou. ʻO Tianjin Zhengneng Pipe Industry Co., Ltd. kahi ʻoihana ʻoihana e hoʻohui ana i ka hana pipeline, kūʻai aku a hoʻokuʻu aku. ʻO nā huahana koʻikoʻi o ka ʻoihana e pili ana i nā paipu paila, nā paipu momona, nā paipu ʻaila a me nā paipu kūkulu.
Hoʻokumu ʻo Zhengneng Pipe Industry i ka hāʻawi ʻana i ka papahana hilinaʻi a waiwai a me nā hopena hana i nā mea kūʻai aku a me nā hoa hana a puni ka honua, me ka ʻoihana boiler, ka ʻaila a me ka ʻoihana kinoea, mālama wai, mining, ʻoihana ikehu a me nā ʻoihana mīkini. Kūʻai ʻia nā huahana i ka Hikina Hema, ʻAmelika Hema, ʻAmelika Hema a me ʻAmelika Hema.
I kēia lā e hoʻolauna mākou i nā huahana nui o kā mākou hui. ʻO nā huahana koʻikoʻi o kā mākou hui ʻo: Boiler Pipes account no 40%; ʻO nā paipu laina he 30%; He 10% ka paipu petrochemical; ʻO nā paipu hoʻololi wela he 10%; ʻO nā paipu mechanical he 10%.
