Thaum ntxov xyoo 1990, cov tsoos loj cuff tso tawm hoses tseem siv dav hauv cov dredgers hauv Suav teb, cov nominal diameters ntawm cov hoses muaj li ntawm 414mm txog 700mm, thiab lawv cov dredging efficiency tsawg heev. Nrog rau txoj kev loj hlob ntawm Tuam Tshoj txoj kev lag luam dredging, xws li dredging pipelines yog nce tsis haum rau cov kev xav tau ntawm dredging tej yaam num. Txhawm rau hloov qhov xwm txheej no, CDSR pib tshawb fawb thiab tsim Ø700 steel flange tso hose (tso tawm hose nrog steel txiv mis) hauv xyoo 1991, thiab thawj pawg ntawm cov kav dej tau siv los ntawm ntau lub tuam txhab loj dredging hauv Suav teb. Raws li cov txiaj ntsig kev sim, CDSR tau tshawb xyuas kev txhim kho ntawm cov ntaub ntawv, qauv thiab txheej txheem ntawm cov hose. Tom qab ntawd, nrog kev txhawb nqa ntawm Guangzhou Dredging Company, 40 qhov ntev ntawm cov hlau flange tso tawm hoses uas tsim los ntawm CDSR tau siv rau hauv qhov project reclaiming ntawm Macao tshav dav hlau piv nrog cov hoses muab los ntawm lwm cov tuam txhab.
Raws li kev ua tau zoo thiab kev ua haujlwm ntawm 40 txoj kab hoses, CDSR txhim kho cov ntaub ntawv, qauv thiab txheej txheem ntawm lub hose thiab muab cov hoses txhim kho dua. Thaum kawg, CDSR's steel flange discharge hoses tau lees paub thiab qhuas los ntawm tus neeg siv, thiab lawv cov ntsuas kev ua tau zoo tsis muaj tsawg dua li cov neeg tuaj txawv teb chaws. Kev tshawb fawb thiab kev txhim kho ntawm CDSR cov hlau flange tawm hose tau tshaj tawm tias ua tiav. Txij thaum ntawd los, nws tau dhau los ua qhov kev txiav txim siab ua ntej uas cov hlau flange tso tawm hoses yuav siv dav hauv cov dredgers loj hauv Suav teb.
Xyoo 1997, CDSR tau muab Ø414 steel flange tso tawm hoses rau 200 m³ dredger tshiab ntawm Nantong Wenxiang Dredging Company, thiab tom qab ntawd cov hoses no tau siv rau hauv qhov project dredging hauv Bengbu. Thaum Lub Rau Hli 1998, 12 Lub Rooj Sib Tham Hauv Lub Tebchaws Dredging thiab Reclaiming Technology kuj tseem muaj nyob rau hauv Bengbu, cov Ø414 steel flange tso tawm hoses sai sai tau los ua qhov tseem ceeb ntawm lub rooj sib tham ntawm qhov chaw, nyiam txhua tus neeg mloog. Tom qab lub rooj sib tham, cov hlau flange tawm hoses tau nce sai thiab siv nyob rau hauv Tuam Tshoj raws li ib tug zoo hloov ntawm enlarged cuff discharge hoses. Txij thaum ntawd los, CDSR tau tsim txoj hauv kev tshiab rau Tuam Tshoj txoj kev lag luam dredging hauv kev hloov pauv, siv thiab tsim cov dredging hoses.
Ntau tshaj 30 xyoo dhau los, kev tsim khoom tshiab tas li yog lub ntsiab lus nyob mus ib txhis ntawm CDSR. Nws cov khoom tsim kho tshiab thiab thev naus laus zis tshiab, xws li kev txhim kho hose reinforcement, kev vam meej ntawm kev tso tawm hose, kev txhim kho ntawm armored hoses, thiab kev vam meej ntawm offshore roj hoses (GMPHOM 2009), thiab lwm yam. CDSR yuav tuav nws txoj kev coj noj coj ua zoo, txuas ntxiv mus ua raws li txoj hauv kev ntawm kev tsim kho tshiab, thiab siv zog los ua lub ntiaj teb-chav tsim khoom lag luam loj ntawm cov roj hmab hoses.
