Selemo se secha se tlisa qalo e ncha. Tianjin Zhengneng Pipe Industry Co., Ltd. ke kgwebo ya profeshenale e kopanyang tlhahiso ya diphaephe, thekiso le ho romela kantle ho naha. Dihlahiswa tse ka sehloohong tsa khamphani di kenyeletsa diphaephe tsa boiler, diphaephe tsa manyolo, diphaephe tsa peterole le diphaephe tsa meaho.
Indasteri ea Zhengneng Pipe e ikemiselitse ho fana ka litharollo tsa merero le tsa ts'ebetso tse tšepahalang le tsa bohlokoa ho bareki le balekane lefatšeng ka bophara, ho kenyeletsoa indasteri ea liboiler, indasteri ea oli le khase, paballo ea metsi, indasteri ea merafo, indasteri ea matla le indasteri ea lisebelisoa tsa mechini. Lihlahisoa li rekisetsoa Asia Boroa-bochabela, Bochabela bo Hare, Amerika Leboea le Amerika Boroa.
Kajeno re tla hlahisa dihlahiswa tse ka sehloohong tsa khamphani ya rona. Dihlahiswa tse ka sehloohong tsa khamphani ya rona ke: Diphaephe tsa Boiler di etsa 40%; diphaephe tsa mohala di etsa 30%; diphaephe tsa peterole di etsa 10%; diphaephe tsa mocheso di etsa 10%; diphaephe tsa mechini di etsa 10%.
