UDonsen unomlando omude futhi ungumkhiqizi ochwepheshile wamapayipi, okokufaka kanye namavalvu. I-Donsen yasungulwa ngo-1996, e-Ningbo, e-China, okuwumnotho othuthukile kanye nedolobha lezokuthutha elilula. UDonsen ungomunye wabakhiqizi abanohlelo oluphelele lomkhiqizo emkhakheni wamapayipi epulasitiki eChina.
Njengamanje, iqembu le-Donsen likhiqiza ikakhulukazi uchungechunge lwe-valve: i-valve ye-PPR, i-valve ye-PVC, i-valve ye-CPVC, i-valve ye-PE nezinye izinhlobo ze-valve yepulasitiki yethusi;Uchungechunge lokwakhiwa kwamanzi: ukufakwa kwepayipi le-PPR, ukufakwa kwe-PPR okusheshayo, ukufakwa kwepayipi leplastiki yethusi, njll. Uchungechunge lokuhlinzeka ngamanzi ezimbonini: Ukufakwa kwepayipi le-PE, njll.Uchungechunge lokuvikela umlilo womphakathi: Ukufakwa kwepayipi le-CPVC, njll.Ukuchelela amanzi okonga amanzi: Ukufakwa kwepayipi lokucindezela kwe-PP, ukufakwa kwepayipi le-PE, njll.Uchungechunge lokushisa okushisa: Ipayipi lokushisa eliphansi le-PERT, umsabalalisi wamanzi, njll.Inkampani yethu nayo inokukhiqiza isikhunta sepulasitiki: isikhunta sepayipi ye-PPR, isikhunta se-PPV, isikhunta se-PVC Ngesikhathi esifanayo, sisenochungechunge lwama-valve okufakwayo okufanele luthuthukiswe: uchungechunge lokufakwa kwamapayipi okuvamile aseMelika, uchungechunge lokufakwa kwamapayipi okuvamile e-PVC, uchungechunge lwe-DIN olujwayelekile lokufakwa kwepayipi le-PVC nokunye. Imikhiqizo yethu isetshenziswa kakhulu ekuhlinzekeni kwamanzi omphakathi, i-drainage yokwakha, ukuhlinzekwa kwamanzi nokushisa, ukuhlobisa ikhaya nokuchelela engadini, ukuchelela ngenkasa kwezolimo neminye imikhakha.
Ukuze wenze umndeni usebenzise ikhwalithi yemvelo yemikhiqizo yamapayipi, iDonsen yamukela impahla eluhlaza engenisiwe yokukhiqiza imikhiqizo, ukuze kuqinisekiswe ikhwalithi yomkhiqizo, uDonsen wethula umugqa wokukhiqiza wepayipi ohlanganisiwe we-aluminium odongeni osezingeni eliphezulu, njengomugqa wokukhiqiza we-fiberglass, umugqa wokukhiqiza i-PPR wethusi nomugqa wokukhiqiza wepulasitiki, uphindwe kabili umugqa wokukhiqiza ophumelelayo njll. Ngokuphelele 9 umugqa wepayipi othuthukisiwe kanye nesistimu yokutholwa egcwele komjovo wekhompiyutha engaphezu kuka-70 kanye nemishini ehlanganisiwe yokulawula umjovo wekhompyutha. & nokusebenza ngomshini esikhundleni semanuwali ukwenza ukukhiqizwa kweDonsen kuphephe kakhudlwana, kucace kakhudlwana futhi kuqeqesheke kakhulu. Ukuze kuzuzwe ikhwalithi ephezulu engu-100%, uDonsen unokulawula okuqinile nokuhlola ukuhlolwa kwezinto ezibonakalayo ezingenayo, ukuhlolwa kwenqubo, ukuhlolwa kokuthunyelwa, ukuqinisekisa ukugqwesa komkhiqizo.
Kuze kube manje, iDonsen inamafekthri amathathu amakhulu okukhiqiza amapayipi nokufakwa, imboni eyodwa yokubumba, kanye nolunye uhlobo olusha lwesisekelo sokukhiqiza esizenzakalelayo, imboni yeDonsen ineworkshop yesikwele engaphezu kuka-70000, abasebenzi abangaphezu kuka-700 kanye neqembu elilodwa elivelele lobuchwepheshe nokuphatha, isilinganiso seminyaka yobudala yaleli qembu elingaphansi kweminyaka engama-35 ubudala, sinamandla, ukusungula izinto ezintsha kanye nekhono, banganikeza amakhasimende esevisi ephumelelayo. Indlunkulu yaseDonsen (Ifektri) ikhiqiza ngokuyinhloko izifakelo zamapayipi e-PPR, izifakelo zamapayipi e-PE neminye imikhiqizo yokuphakelwa kwamanzi nazo zonke izinhlobo zamavalvu. Imboni ye-B ikakhulukazi ikhiqiza okokufakwa kwamapayipi e-PVC, ukufakwa kwepayipi le-HDPE neminye imikhiqizo yokukhipha amanzi; Imboni ye-C ikhiqiza ngokuyinhloko izifakelo zamapayipi okucindezela e-PP neminye imikhiqizo yezolimo yokonga amanzi. Imboni yokubumba inesibopho ngokuyinhloko sokukhiqizwa kwazo zonke izinhlobo zokubunjwa kwamapayipi futhi imboni entsha izokwandisa kakhulu ukukhishwa kwamapayipi ethu okufakwayo, ama-valve, amapayipi.
Njengamanje, inkampani isiphumelele isitifiketi se-CE se-European Union. Isitifiketi se-NSF e-USA; Isitifiketi se-SABS eNingizimu Afrika; Isitifiketi se-GOST eRussia; Isitifiketi se-WRAS eNgilandi, isitifiketi se-SIAA eJapan; Isitifiketi se-SKZ saseJalimane nezinye izitifiketi.
Imikhiqizo yethu ithunyelwa emazweni angaphezu kuka-100 emhlabeni, njengeRussia, Ukraine, France, Italy, Mexico, Middle East, Europe, South America, Asia, njll. Njengamanje, kukhona ama-ejenti wemikhiqizo yochungechunge lwe-Donsen kuwo wonke amazwe emhlabeni. U-DONSEN uzokusebenzela ngenhliziyo yonke , futhi efuna ama-ejenti .
