Ekuqaleni kweminyaka yoo-1990, imibhobho yokukhupha i-cuff eyandisiweyo yayisasetyenziswa ngokubanzi kwi-dredgers e-China, iidayamitha ezizezinye zezo hoses zisusela kwi-414mm ukuya kwi-700mm, kwaye ukusebenza kwazo kakuhle kokucofa bekuphantsi kakhulu. Ngophuhliso lweshishini lokutsala laseTshayina, le mibhobho yokutsala iyanda ingafanelekanga kwiimfuno zeeprojekthi zokwelula. Ukuze utshintshe le meko, i-CDSR yaqala ukuphanda kunye nokuphuhlisa i-Ø700 yentsimbi yokukhupha i-hose (i-hose yokukhupha nge-steel nipple) ngo-1991, kunye nebhetshi yokuqala ye-hoses yovavanyo yasetyenziswa ziinkampani ezininzi zokudonsa e-China. Ngokweziphumo zovavanyo, i-CDSR yenza uphando oluphuculweyo kwizinto eziphathekayo, isakhiwo kunye nenkqubo ye-hose. Emva koko, ngenkxaso yeNkampani ye-Guangzhou Dredging, ubude be-40 ye-steel flange discharge hoses eveliswe yi-CDSR yasetyenziswa kwiprojekthi yokubuyisela i-Airport ye-Macao xa kuthelekiswa nemibhobho enikezelwa ngabanye abavelisi.
Ngokusekelwe kwintsebenzo kunye neemeko zokusebenza kwee-hoses ze-40 zomzila, i-CDSR iphuculwe izixhobo, isakhiwo kunye nenkqubo ye-hose kwaye inikezela ngee-hoses eziphuculweyo kwakhona. Ekugqibeleni, i-CDSR's steel flange discharge hoses zaqatshelwa kwaye zadunyiswa ngumsebenzisi, kwaye izibonakaliso zabo zokusebenza zazingekho ngaphantsi kwezo zithunyelwa ngaphandle. Uphando kunye nophuhliso lwethumbu lokukhupha intsimbi ye-CDSR ye-flange lubhengezwe njengempumelelo. Ukusukela ngoko, kuye kwaba sisigqibo esingaphambili sokuba i-hoses yokukhupha intsimbi iya kusetyenziswa ngokubanzi kwiidrodi ezinkulu eTshayina.
Ngo-1997, i-CDSR yabonelela ngee-Ø414 zentsimbi yokukhupha imibhobho yentsimbi ye-200 m³ dredger entsha yeNantong Wenxiang Dredging Company, emva koko la mibhobho yasetyenziswa kwiprojekthi yokudiliza e-Bengbu. NgoJuni ka-1998, iNtlanganiso ye-12 yeSizwe yokuGqiba nokuBuyisa ubuChwephesha nayo yabanjwa e-Bengbu, ezi hoses zokukhupha iintsimbi ze-Ø414 ngokukhawuleza zaba yeyona nto iphambili kwintlanganiso ekwisiza, itsala umdla womntu wonke. Emva kwentlanganiso, i-hoses yokukhupha i-flange yensimbi yakhuthazwa ngokukhawuleza kwaye isetyenziswa e-China njengento efanelekileyo yokuthatha indawo ye-cuff yokukhupha i-hoses eyandisiweyo. Ukusukela ngoko, i-CDSR yenze indlela entsha yomzi-mveliso waseTshayina wokudiliza kwinguqu, ukusetyenziswa kunye nophuhliso lwemibhobho yokudonsa.
Ngaphezulu kweminyaka engama-30 idlulile, ukuphuhliswa rhoqo kweemveliso ezintsha kuhlala kungumxholo ongunaphakade weCDSR. Uphuhliso lwayo olutsha lwemveliso kunye nokutsha kwezobuchwepheshe, njengokuphuculwa kokuqinisa ithumbu, uphuhliso oluyimpumelelo lwethumbu lokulahla elidadayo, uphuhliso oluyimpumelelo lwemibhobho ye-armored, kunye nophuhliso oluyimpumelelo lwemibhobho yeoli ye-offshore (GMPHOM 2009), njl.n I-CDSR iya kugcina isithethe sayo esihle, iqhubeke nokubambelela kwindlela yokuqamba izinto ezintsha, kwaye izabalazele ukuba ngumvelisi okumgangatho wehlabathi wemibhobho emikhulu yerabha.
