He ʻāpana koʻikoʻi ka hana ʻeli ʻana i ka wai o ka ʻenekinia moana, ka mea e hōʻoiaʻiʻo ai i ka holo mālie ʻana o nā wahi wai e like me nā awa, nā uapo, a me nā ala wai. Me ka hana hou a me ka hoʻomohala ʻana o ka ʻenehana, ua lilo nā hose ʻeli i ʻāpana koʻikoʻi o nā hana ʻeli ʻana. ʻO ka hana ʻana i nā hana ʻeli ʻoi aku ka maikaʻi, palekana a me ka maʻalahi, ʻo ia ke kuhikuhi noiʻi o CDSR.
Hose ʻeli CDSRʻO ka maʻamau i haku ʻia me ka lining, ka hoʻoikaika, ka uhi waho a me nā hui hose ma nā wēlau ʻelua, me ke kūpaʻa maikaʻi o ke kaomi, ke kūpaʻa flex, ke kūpaʻa tensile, ke kūpaʻa ʻaʻahu, ka sila elastic, ka hoʻomoʻo haʻalulu, ke kūpaʻa ʻelemakule, ke kūpaʻa corrosion a me nā ʻano ʻē aʻe, ua hoʻohana nui ʻia nā hose dredging CDSR i nā papahana dredging.
Fʻanos:
（1）Hoʻopilikino ʻia ke kumu ma ka lawe ʻana i nā mea
（2）ʻO ke kūpaʻa maikaʻi loa i ka ʻaʻahu a me ka palaho
（3）Mahana hana kūpono: -20°C a 50°C
（4）Can kamaʻilio ʻanae hoʻomaʻemaʻe mālie i nā mea ke kulou ʻia i kekahi ʻano
（5）ʻO ka flange i hoʻopili ʻia me ka sila, e hōʻoiaʻiʻo ana i ka sila maikaʻi ma waena o nā flanges i hoʻopili ʻia
（6）Kaomi hana a me ka nui o ka flange ma ke noi
（7）Hoʻonohonoho maʻalahi, manawa lawelawe lōʻihi, ākea o nā noi
ʻO ka CDSRpaipu hoʻoheheʻeisloaʻa me ʻeluanā ʻano hono——nā nipple kila a me nā flanges sandwich.Hiki ke wehewehe ʻia nā Flanges he mau mea nui i hoʻohana ʻia e hoʻopili i nā paipu, nā valves, nā pamu a me nā lako ʻē aʻe.ʻO ka paipu waimeʻaoʻao sanwikanāhe kūpaʻa maikaʻi komi a me ka hana kūlou, ait hoʻohana pinepine ʻia ma nā ʻāpana kūikawā o ka waʻa hana, e like me: ka lima rake o ka dredger omo hopper hope, ka pilina alahaka o ka mea ʻoki omo dredger, a me nā ʻāpana mua a me hope o kepamu,a pēlā aku. ʻO ka hose me ka nipple kila he kūpaʻa maikaʻi kona, ka maʻalahi a me ke kūpaʻa tensile, a hoʻohana pinepine ʻia i lokolana ananā paipu. Loaʻa i ka flange o ka hose CDSR ka hana sila maikaʻi, hiki ke pale pono i ka liki ʻana o ka wai a me nā mea haumia a pale maikaʻi i ke kaiapuni kaiaola i ka wā e hoʻohana ai i ka hose no nā hana dredging.
He mea koʻikoʻi nā uhi pale i ka abrasion i ka hana hose, a me ka ʻoi aku o 50 mau makahiki o ka ʻike ʻoihana, loaʻa iā CDSR ka ʻike e koho i nā lako dredging maikaʻi loa no kāu noi kikoʻī.
I nā hana dredging, pono pinepine ka lawe ʻana i ka nui o ka sediment, gravel a me nā mea ʻē aʻe. Ua hoʻolālā mākou i nā ʻano hose like ʻole no nā mea like ʻole. Hiki i nā hose dredging maʻamau ke lawe i ka wai (wai kai), silt, lepo, ka hui ʻana o ka lepo a me ke one. ʻO kahose pale kauaua hoʻokomo ʻia me ke apo kila pale ʻaʻahus, kūpono loa no nā kūlana hana paʻakikī ʻaʻole hiki i nā hose dredging maʻamau ke hoʻomanawanui no ka lōʻihi. He kūpono ia no ka lawe ʻana i nā mea pālahalaha angular, paʻakikī, a me nā ʻano nui e like me nā koʻa a me nā pōhaku i hoʻopau ʻia.
Pono ka hoʻokō ʻana o nā hana dredging i ka maʻalahi kiʻekiʻe no ka mea e pili ana i nā kumu he nui e pili ana i ka wai, ka geology, ka ecology, a me nā mea ʻē aʻe. E hāʻawi mākou iā ʻoe i nā lawelawe maʻamau piha asa mekākoʻo loea kiʻekiʻema muli okāu mau pono papahana kikoʻī, hōʻoiaanai hiki ke hoʻokō pono ʻia kāu papahana.
