Ehara i te mea he whakapai ake hangarau noa iho te kawe mai i tētahi Pūnaha Papu Korehau Hihiri ki roto i tētahi tipu cryogenic o nāianei—he mahi toi anō hoki. Me tino tika koe, me mārama ki te whakamahana korehau, me te momo wheako ka puta mai i te mahi tahi me te hoahoa paipa cryogenic i ia rā, i ia rā. E mārama ana a HL Cryogenics ki tēnei. Hei ingoa ao mō ngā paipa cryogenic, ka aro nui rātou ki ia wahi e hangaia ana e rātou, kia whiwhi ai koe i te mahi pono, whai hua hoki—ahakoa ka heke te pāmahana ki raro iho i te kore. Ko tā rātou raina—Paipa Whakamarumaru Korehau, Ngongo Ngāwari, Vale, Wehewehe Wāhanga, me te Pūnaha Papu Korehau Hihiri—ka mahi tahi hei rōpū kia mau tonu te kounga o te korehau me te rere pai o te hau wai.

TePūnaha Papu Korehau Hihiriehara i te mea he tāpiri noa iho. Koinei te kaupapa o te pupuri i te whai huatanga o ngā pūnaha LN₂, ngā whakaurunga LNG, me ngā paipa hāora wai. He māmā noa te whakaaro: me whai wāhi hohonu te korehau i waenganui i ngā pakitara maitai kore waikura o roto, o waho hoki o ia paipa cryogenic hei aukati i te wera. Heoi, i roto i te wā, ka taea e ngā paipa pai rawa te ngaro i te korehau—he turuturu iti pea, he putanga hau iti pea. Koinei te wāhi e whai wāhi mai ai te pūnaha HL Cryogenics. Ka tangohia anō e ia te wāhi korehau ina hiahiatia, ka pupuri i te whakamarumaru pai rawa atu, ā, ka whakarite kia roa te ora o tō pūnaha.

Ina whakatikatika a HL Cryogenics i tētahi mahi whakahou, ka tīmata ā rātou kaihangarau mā te ruku ki roto i te tahora o tō tipu—mā te tirotiro i te whatunga paipa, te pēhanga, me te nekehanga o te wera mā roto i te pūnaha. I te nuinga o te wā ka honoa e rātou te pūnaha papu ki ngā putanga korehau kua tohua i runga i ngā paipa, i ngā takirere rānei e ngāwari ana te toro atu me te whakahaere. Ka honoa e te ngongo ngāwari ngā wae papu ki ngā wāhanga paipa rerekē, kia mau tonu te korehau me te kore e tāpiri i te ahotea, i ngā ara wera koretake rānei.

I roto i tePūnaha Papu Korehau Hihiri, ka kitea e koe ngā papu roughing me ngā papu turbomolecular kaha, e hono katoa ana ki ngā manifolds kowiri tira tika. Ka aroturuki tonu ngā ine mamati me ngā kaiwhakahaere atamai i ngā taumata korehau, ka pupuri i a rātou i roto i te awhe 10⁻³ ki te 10⁻⁵ mbar—he mea nui tēnei hei pupuri i te wera kia kore e puta, kia pumau hoki ō cryogenics.

He tino painga tēnei whakaritenga: he pai ake te pai o te wera, he iti ake te ngaronga o te hau wai, me ngā tukanga pumau. I roto i ngā tipu haurua-ira, ka whiwhi koe i ngā hua ōrite ake. I roto i te rokiroki cryogenic hauora, ko te tikanga o te korehau pumau he hāora wai pono, he argon rānei. I ngā teihana LNG nui, ka tautokohia e ia te mahi tonu, ka whakaiti i te hau kohua, ā, ka whakaiti i te wā whakatā.
