Ko te rokiroki me te kawe i te hauwai wai te pūtake o te whakamahinga haumaru, whai hua, nui, me te iti o te utu o te hauwai wai, ā, koinei anō hoki te huarahi matua ki te whakaoti rapanga i te whakamahinga o te hangarau hauwai.
 
E rua ngā momo o te rokiroki me te kawe i te hauwai wai: te rokiroki ipu me te kawe paipa. Mēnā he hanganga rokiroki, ka whakamahia te tāke rokiroki porowhita me te tāke rokiroki porotaka mō te rokiroki me te kawe ipu. Mēnā he waka kawe, ka whakamahia te wakatō hauwai wai, te waka tāke tereina hauwai wai, me te kaipuke tāke hauwai wai.
 
Haunga te whakaaro ki te pānga, te wiri me ētahi atu āhuatanga e pā ana ki te tukanga kawe wai tuku iho, nā te iti o te kohua o te hauwai wai (20.3K), te iti o te wera huna o te mimiti me ngā āhuatanga mimiti ngāwari, me whakamahi te rokiroki me te kawe ipu i ngā tikanga hangarau tino pakari hei whakaiti i te turuturu wera, me whakamahi rānei i te rokiroki me te kawe kore-whakangaro, hei whakaiti i te nui o te mimiti o te hauwai wai ki te iti rawa, ki te kore rānei, ki te kore ka piki ake te pēhanga o te tāke. Ka arahi ki te mōrearea o te pēhanga nui, te ngaronga rānei o te pupuhi. E ai ki te pikitia i raro nei, mai i te tirohanga a ngā huarahi hangarau, ko te rokiroki me te kawe hauwai wai te nuinga o te whakamahi i te hangarau adiabatic kore mahi hei whakaiti i te kawe wera me te hangarau whakamatao hohe e honoa ana i runga i tēnei kaupapa hei whakaiti i te turuturu wera, hei whakaputa rānei i te kaha whakamatao tāpiri.
 
I runga i ngā āhuatanga ā-tinana me te matū o te hauwai wai, he maha ngā painga o tōna momo rokiroki me te kawe i te momo rokiroki hauwai hau pēhanga-tiketike e whakamahia whānuitia ana i Haina, engari nā te uaua o te tukanga whakaputa, he ngoikoretanga anō hoki ōna.
 
He nui te ōwehenga taumaha rokiroki, he watea te rokiroki me te kawe waka me te waka
Ki te whakaritea ki te penapena hauwai hau, ko te painga nui o te hauwai wai ko tōna matotorutanga teitei. Ko te matotorutanga o te hauwai wai he 70.8kg/m3, arā, he 5, 3 me te 1.8 ngā wā o te hauwai pēhanga teitei 20, 35, me te 70MPa. Nō reira, he pai ake te hauwai wai mō te penapena me te kawe i te hauwai i roto i te tauine nui, ka taea ai te whakaoti i ngā raruraru o te penapena me te kawe i te pūngao hauwai.
 
He iti te pēhanga rokiroki, he ngāwari ki te whakarite i te haumaru
Mā te rokiroki hauwai wai i runga i te kaupapa o te whakamarumaru, ka pumau te ipu, he iti te taumata pēhanga o te rokiroki me te kawe i ia rā (i raro iho i te 1MPa), he iti rawa atu i te taumata pēhanga o te rokiroki me te kawe hau me te hauwai pēhanga teitei, he māmā ake te whakarite i te haumaru i roto i te tukanga mahi o ia rā. I te whakakotahitanga me ngā āhuatanga o te ōwehenga taumaha rokiroki hauwai wai nui, ā, i te heke mai, ka whai pūnaha whakahaere haumaru ake te whakatairanga nui o te pūngao hauwai, te rokiroki me te kawe hauwai wai (pērā i te teihana hauwai hauwai wai) i ngā tāone nui he nui te kiato o ngā whare, he kiki te taupori me te utu whenua nui, ā, ka kapi te pūnaha whānui i tētahi rohe iti ake, me te iti ake o te utu haumi tuatahi me te utu whakahaere.
 
Teitei o te parakore o te mimiti, e tutuki ana i ngā whakaritenga o te pūrua
He nui te whakamahinga ā-tau o te hauwai parakore teitei me te hauwai tino parakore o te ao, inā koa i roto i te umanga hikohiko (pēnei i ngā haurua-ira, ngā rauemi hiko-korehau, ngā papa silicon, te hanga muka whatu, me ētahi atu) me te mara pūtau wahie, kei reira te whakamahinga nui o te hauwai parakore teitei me te hauwai tino parakore. I tēnei wā, kāore e taea e te kounga o te maha o ngā hauwai ahumahi te whakatutuki i ngā whakaritenga pakari a ētahi kaiwhakamahi mutunga mō te parakore o te hauwai, engari ka taea e te parakore o te hauwai i muri i te mimiti o te hauwai wai te whakatutuki i ngā whakaritenga.
 
He nui te haumitanga o te tipu wai, ā, he nui hoki te whakamahinga pūngao
Nā te whakaroa o te whanaketanga o ngā taputapu me ngā hangarau matua pērā i ngā pouaka makariri whakapūnga hauwai, ko ngā taputapu whakapūnga hauwai katoa i roto i te ao rererangi ā-rohe i raro i ngā kamupene o tāwāhi i mua i te marama o Hepetema 2021. Ko ngā taputapu matua whakapūnga hauwai nui kei raro i ngā kaupapa here hokohoko ā-rohe e tika ana (pērā i ngā Ture Whakahaere Kaweake o te Tari Tauhokohoko o Amerika), e aukati ana i te kaweake o ngā taputapu me te aukati i te whakawhitiwhiti hangarau. Nā tēnei ka nui te haumitanga taputapu tuatahi o te tipu whakapūnga hauwai, me te iti o te tono ā-rohe mō te hauwai wai ā-iwi, kāore i te rawaka te tauine tono, ā, ka puhoi te pikinga o te tauine kaha. Nō reira, he nui ake te whakapaunga pūngao whakaputa kotahi o te hauwai wai i te hauwai hau pēhanga teitei.
 
Ka ngaro te mimiti i roto i te tukanga rokiroki me te kawe hauwai wai.
I tēnei wā, i roto i te tukanga rokiroki me te kawe hauwai wai, ko te mimiti o te hauwai i puta mai i te turuturu wera ka rongoatia mā te whakaputa hau, ka arahi ki te ngaronga o te mimiti. I roto i te rokiroki me te kawe pūngao hauwai ā muri ake nei, me mahi ētahi atu mahi hei whakaora i te hau hauwai kua mimiti hei whakaoti i te raruraru o te whakaiti i te whakamahinga i puta mai i te whakaputa hau tika.
 
Taputapu Cryogenic HL
I whakatūria a HL Cryogenic Equipment i te tau 1992, ā, he waitohu hono ki te HL Cryogenic Equipment Company Cryogenic Equipment Co.,Ltd. E whakapau kaha ana a HL Cryogenic Equipment ki te hoahoa me te hanga i te Pūnaha Paipa Cryogenic Ārai Korehau Teitei me ngā Taputapu Tautoko e pā ana ki tēnā hei whakatutuki i ngā hiahia o ngā kiritaki. He mea hanga te Paipa Ārai Korehau me te Ngongo Ngāwari ki ngā rauemi ārai motuhake ārai korehau teitei me te maha-paparanga maha-mata, ā, ka tukuna mā roto i te raupapa o ngā maimoatanga hangarau tino pakari me te maimoatanga korehau teitei, e whakamahia ana mō te whakawhiti i te hāora wai, te hauota wai, te hauhā wai, te hauwai wai, te hēriuma wai, te hau ethylene wairewa LEG me te hau taiao wairewa LNG.
