I-DHDZ iyindinganiso kazwelonke enomkhiqizi we-Flange Flange. Le nkampani inamandla aqinile wezobuchwepheshe, ingakwazi ukuklama nokwakha imininingwane ekhethekile ekhethekile yemikhiqizo efanelekile yepayipi ngokuya ngezidingo zomsebenzisi. Ngokuhlolwa kwe-metallographic, ukuhlolwa ngokomzimba, ukuhlaziya kwamakhemikhali, ukuhlolwa okungelonakalisa okulimazayo neminye imishini yokuhlola okuthuthukile nezindlela.
Abakhiqizi be-Flange bazibandakanyeka kakhulu ku: I-GB Intamo ye-Flange, i-Flat Flat Welding Flange, i-Flange engekho emthethweni kanye nezinye izinhlobo zezinyawo zentamo. Ngitshala nginenombolo enkulu yemishini yamapayipi abasebenzi abasemuva, imishini ethuthukisiwe ebekiwe kanye ne-metallography ebukekayo, ukutholwa kwefishi, ukuhlolwa okugcwele kwemishini yokuhlola, inkampani isebenzisa ngokuqinile uhlelo lokulawulwa okujwayelekile. Usungule uhlelo lokuqinisekisa ikhwalithi yesayensi, uhlelo lokuqinisekisa ikhwalithi ephelele kanye nobuchwepheshe bokukhiqiza lwesayensi kuqinisekisa ikhwalithi yomkhiqizo.

Abakhiqizi be-DHDZ Flange basetha umnyango wokulawula osezingeni eliphezulu kanye nesikhungo sokuhlola amapayipi aphezulu kanye nokutholwa kwepayipi okuphakathi nendawo okuphansi, okutholwa kwe-FASPET, ukuhlolwa kwe-meallokic, ukuhlolwa kwe-mechation, ukuhlolwa kwengcindezelo yamanzi, ukuhlolwa kwengcindezelo yamanzi, ukuhlolwa kwengcindezelo, ukuhlolwa kwengcindezelo, ukuhlolwa okubonakalayo, ukuhlolwa okubonakalayo, Ukuqapha okwenziwe nge-infrared nezinye izinto zokuhlola.
Abakhiqizi be-Flange ye-China GB Abakhiqizi - Win ngekhwalithi, inzuzo encane kodwa baqhubeka nomgomo wokuthola imali, ekuncintisaneni okuvuthayo kwemakethe, ngokubambisana okuhle nokubambisana okuqotho nomoya wokusebenza oqotho ukuzuza iningi lamakhasimende ukwethembana nokuthuthuka okusheshayo. Ukuseza phambili, ukuphishekela ubuhle, ukufunda okuqhubekayo, akukaze kwanelisekile ngenkolelo yamakhasimende ethu ukudala isimo sokuwina esiphindwe kabili, kwakha ikusasa elingcono.
