Pōtae Porowhita Porowhita Cryogenic mō te -196 ℃
✧ Whakaahuatanga
He takirere porowhita Cryogenic me te taupoki whānui e whakamahia ana mō te -196℃, e whakamahia whānuitia ana i roto i te umanga matū, te hinu, te hau māori, te whakarewa, te hiko me ētahi atu umanga. Ko te takirere porowhita maitai hanga he hanganga kua oti te whakarewa, ā, ko te tinana takirere me te kuaha he mea hanga ki ngā wāhanga maitai hanga. He pai te mahi hiri o te takirere, he kaha te ātete ki te waikura me te roa o te ora mahi. He māmā tōna hanganga, he iti te rahi, he ngāwari ki te tāuta me te tiaki. He ngāwari te pana kuaha, ā, ka taea te tapahi katoa i te rere waenga me te kore e turuturu. He whānui te awhe pāmahana o te takirere porowhita maitai hanga me te pēhanga mahi teitei, ā, ka taea te whakamahi mō te whakahaere rere waenga i raro i te pāmahana teitei me te pēhanga teitei me te pāmahana iti me te pēhanga teitei.
✧ Ngā Āhuatanga o te API 602 Cryogenic Globe Valve Extended Bonnet mō te -196℃
1. He māmā ake te hanganga i te takirere porowhita, ā, he watea ake te hanga me te tiaki.
2. Kāore te mata hiri e ngāwari ki te mau, ki te rakuraku, ā, he pai te mahi hiri. Kāore he reti tata i waenga i te kōpae takirere me te mata hiri o te tinana takirere ina whakatuwheratia, ina kati rānei, nō reira kāore te mau me te rakuraku e kino, he pai te mahi hiri, ā, he roa te ora ratonga.
3. He iti te whiu o te kōpae ina whakatuwheratia, ina kati hoki, nō reira he iti ake te teitei o te takirere aukati i te takirere porowhita, engari he roa ake te roa o te hanganga i te takirere porowhita.
4. He nui te taipana whakatuwheratanga me te katinga, he uaua te whakatuwheratanga me te katinga, ā, he roa te wā whakatuwheratanga me te katinga.
5. He nui te ātete wai, nā te mea he pōturi te hongere reo i roto i te tinana takirere, he nui te ātete wai, ā, he nui te whakapaunga hiko.
6. Te ahunga rere o te reo Ina te pēhanga ingoa PN ≤ 16MPa, ka rere whakamua te reo, ka rere whakarunga mai i raro i te kōpae takirere; ina te pēhanga ingoa PN ≥ 20MPa, ka rere whakamuri te reo, ka rere whakararo mai i runga i te kōpae takirere. Hei whakanui ake i te mahi a te hiri. Ina whakamahia, ka taea anake te rere o te reo takirere porowhita i te kotahi ahunga, ā, kāore e taea te whakarerekē i te ahunga rere.
7. Ka memeha te kōpae ina tuwhera katoatia.
✧ Ngā Painga o te takirere porowhita maitai whakarewa API 602
I te wā e whakatuwheratia ana, e kati ana hoki te takirere porowhita maitai hanga, nā te mea he iti ake te waku i waenga i te kōpae me te mata hiri o te tinana takirere i tērā o te takirere porowhita, ka ātete ki te kakahu.
He poto noa te whiu whakatuwheratanga, te whiu kati rānei o te kakau takirere, ā, he tino pono te mahi tapahi, ā, nā te mea he rite te huringa o te putanga nohoanga takirere ki te whiu o te kōpae takirere, he tino pai mō te whakatikatika i te tere rere. Nō reira, he tino pai tēnei momo takirere mō te tapahi, te whakahaere rānei me te whakawhāiti.
