Mena kei te hoko koe i ngā taputapu cryogenic i Ūropi, kāore e taea e koe te karo i te tiwhikete CE i raro i te Pressure Equipment Directive (PED 2014/68/EU). Ko ngā mea katoa e rere ana i runga ake i te 0.5 pae me whai tohu CE—kāore he okotahi. I te US, ko te ASME te paerewa matua. Ka kite koe i te ASME B31.3 mō ngā paipa me te ASME Wāhanga VIII mō ngā oko pēhanga, inā koa mō te ratonga cryogenic. Kātahi ka whai koe i ngā paerewa ISO—ISO 9001 mō te whakahaere kounga, ISO 21009 mō ngā oko whakamahana korehau pao—e tonoa ana e te tini o ngā kaimahi EPC me ngā kaiwhakahaere tipu huri noa i te ao. Hei tāpiri atu ki ēnā mea katoa, ka whakatakotohia e ngā whenua takitahi ā rātou ake waehere. Hei tauira, ka whakamahia e Haina te raupapa GB/T 18442 mō ngā oko pēhanga cryogenic whakamahana korehau pumau. I HL Cryogenics, kei a mātou ngā tiwhikete ASME, CE, me ISO, kia taea ai e mātou te hanga pūnaha cryogenic e rite ana ki ngā whakaritenga ture ā-motu.
He aha te hiranga o tēnei tiwhikete katoa? Ehara ngā pūnaha cryogenic i ngā taputapu tukatuka noa. Ina neke koe i te hauota wai i te -196°C, i te LNG rānei i te -162°C—tae atu ki te hauwai wai i te -253°C—kāore he wāhi mō ngā hapa. Kotahi te hapa iti pēnei i te whakarewa kino, i te rauemi rānei kāore e taea te tu atu i te makariri ka raru nui, ka tūpono hoki te tangata ki te mōrearea. Koia te take e tohe ana ngā whenua ki te tiwhikete pakari mō ēnei taputapu—ehara i te mea he mea whakarite noa iho. Mā ēnei ture ka whakarite kia tika te hoahoa o ngā taputapu, kia hangaia mai i ngā rauemi tika, kia roa te hanga, kia haumaru hoki te whakamahi mō te wā roa.
Nō reira, mō te hunga e whakahaere ana i ngā kirimana hoko, e whakahaere ana rānei i ngā kirimana EPC, ko te kimi i ngā tiwhikete e hiahiatia ana e tō kaupapa te mea tuatahi hei tohu. Ko te huarahi tēnei e karo ai koe i ngā take ture, e karo ai i ngā ohorere kino i ngā tari taake, me te karo i ngā whakaroa i te whakatūnga. Kāore ngā ture tiwhikete e ōrite ana i ngā wāhi katoa—ka rerekē i ia whenua ki ia whenua, i ia pūnaha ki ia pūnaha, ā, e whakawhirinaki ana ki ngā taipitopito pēnei i te pēhanga me ngā pāmahana whakahaere. Mā te tika o te mahi mai i te tīmatanga, ka kore e pāngia te katoa e te maha o ngā raruraru.

Te Kotahitanga o Ūropi: Te Anga Tohu PED me te CE
I Ūropi, ki te hiahia koe ki te hoko, ki te tāuta rānei i tētahi pūnaha cryogenic, me tutuki e koe ngā whakaritenga tohu CE i whakatakotoria e te Pressure Equipment Directive (PED 2014/68/EU). Ka whai mana te PED mō ngā taputapu katoa, ngā huihuinga rānei me te pēhanga mōrahi e whakaaetia ana i runga ake i te 0.5 pae. Nō reira, tata ki ngā pūnaha cryogenic ahumahi katoa—ahakoa hePaipa Whakamarumaru Korehauwhatunga, he rāneiNgongo Ngāwari Whakamarumaru Korehau—me tutuki. Kāore rawa he huarahi hei karo mēnā kei te mahi koe i roto i te EU.
Ka whakarōpūhia e te PED ngā taputapu ki ngā kāwai, i runga i ngā mea pēnei i te pēhanga, te rōrahi, me te mōrearea o te wai. Kei ia kāwai tana ake rārangi mahi hei whakamana. Tērā pea me whai rōpū whakamōhio koe hei tirotiro i tāu mahi, hei whakamātautau momo, hei whakatū rānei i tētahi pūnaha whakaū kounga kua whakaaetia. Ina mahi mātou me tētahi mea pēnei i tā mātouTakirere Whakamarumaru Korehaus rāneiWehewehe Wāhanga Whakamarumaru KorehauKo te tikanga o te tutuki i ngā whakaritenga PED me tautoko e koe ō tataunga pēhanga, me whakahaere ngā whakamātautau wai me te hau, me whakarite kei te taea te whai i ngā rauemi, ā, me te whakamana i te tirotiro tutuki whakamutunga.
Heoi anō, he nui atu anō ngā mea. Ehara i te mea ko te PED anake te mea me whai koe. He maha ngā ture hangarau motuhake kei roto i ngā paerewa EN kua whakaōritehia. E whakamārama ana te EN 12501 i ngā whakaritenga rauemi mō ngā pāmahana iti. E kapi ana te EN 13648 i ngā taputapu haumaru i roto i ngā tautuhinga cryogenic. E whakamārama ana te EN 10204 i ngā mea e hiahiatia ana e koe mō ngā pepa whakamātautau rauemi me te tiwhikete. I te katoa, ka honoa e ēnei paerewa ngā mea katoa, me te whakarite kia tutuki i ia wāhanga—mai i te paipa o roto, te koti o waho, tae noa ki te putanga korehau—ngā paerewa kounga me te haumaru Pākehā tino pakari.
Te Hononga o Amerika: Te Pūnaha Waehere ASME
Mā te whakakotahi i ā mātouPūnaha Papu Korehau Hihiri, Takirere Whakamarumaru Korehau, meWehewehe Wāhanga, ka hoatu e mātou he whakaritenga hei neke i te hēriuma wai me te whakaiti i ngā utu. Ā mātouTāke ItimeNgā Ngongo NgāwariTukua mātou kia whakahaere i ngā mahi pūkoro me ngā mahi pumau me te tino tika.
Ko te paerewa e whakamahia ana mō te tiwhikete taputapu cryogenic i te United States ko te pūnaha waehere a te American Society of Mechanical Engineers (ASME). Ko te ASME B31.3 Process Piping e whakatakoto ana i ngā paerewa whānui e pā ana ki te hangarau, te hoahoa, te hanga, te huihuinga, te whakatūnga, te whakamātautau, te tirotiro, me te whakamātautau i ngā paipa i roto i te ratonga cryogenic. Kei roto hoki i ēnei paerewa ngā whakaritenga mō te ratonga wai pēhanga teitei, ngā paerewa rauemi, me te whakamātautau kore-whakangaro o ngā hononga whakarewa.
Mō ngā oko pēhanga, ko te hoahoa me te hanga o ngā wāhanga kei roto te pēhanga e whakahaeretia ana e te Wāhanga VIII o te ASME. Mō ngā oko pēhanga cryogenic, kei roto i te Wāhanga VIII o te ASME Wāhanga 1 ngā whakatakotoranga taipitopito mō te tatau i te matotoru o te anga, te whakapakari i te pūwero, me ngā taputapu whakamāmā pēhanga.
Kua whakamanahia ā mātou kaimahi e HL Cryogenics mō te Welder, te Welding Procedure Specifications (WPS) me te Kore-whakangaro, tae atu ki te Tiwhikete Pūnaha Kounga ASME. Ehara i te mea he mahi whakamiharo noa iho tēnei; engari, he whakamana whai take i ā mātou tukanga hanga e tutuki ana i ētahi o ngā paerewa tino pakari o te umanga.
Ngā Paerewa o te Ao me Haina: Ngā Paerewa ā-Motu o GB/T
Ka taea e ngā paerewa ISO te whakamahi hei paearu ā-ao mō ngā kaupapa e horapa ana i ngā rohe maha, hei taahiraa whakahaere kounga anō rānei mō ngā tīma hoko. Ko te tikanga o te tiwhikete ISO 9001 kua aromatawaitia tētahi kamupene i runga i te tikanga whakahaere kounga pai rawa atu. I roto i te HL Cryogenics, ka pā te ISO 9001 ki ngā wāhanga katoa o te tukanga hanga hua, mai i te whiwhinga o ngā rauemi ki ngā tirotiro whakamutunga me te tuku.
Mō ngā oko waikura kua whakamahanatia ki te korehau, ka hoatu e te ISO 21009 (Ipu Waikura – Ipu waikura pumau) ngā paearu taipitopito e pā ana ki te hoahoa, te hanga, te tirotiro me te whakamātautau i aua oko. E pā ana te Wāhanga 1 o te paerewa ki te hoahoa o te oko, ā, e pā ana te Wāhanga 2 ki te whakahaere o te oko. Ko te tutuki i ngā paerewa ISO 21009 e tohu ana kua hoahoatia, kua hangaia hoki he Tanka Iti, he oko pumau rānei, me ngā āhuatanga whakamahana korehau e mau tonu ana i roto i tōna oranga mahi.
Kei roto i te raupapa GB/T 18442 ngā whakaritenga hangarau mō ngā oko pēhanga waikura korehau pumau i Haina, ngā taputapu waikura rānei hei hanga ki Haina hei kaweake ki ētahi atu whenua. Ko te Wāhanga 5 o GB/T 18442 e pā ana ki ngā tikanga whakamātautau me te tirotiro i te wā e hangaia ana, ā, i muri hoki i te hanganga o aua hua. Kei roto i te raupapa GB/T 18443 ngā tikanga whakamātautau mō te mahi a ngā taputapu waikura korehau, me ētahi atu ko te whakatau i te tere mimiti pumau. Ka tutuki te tukanga hanga HL Cryogenics i ēnei paerewa ā-motu katoa.
Te Take Hangarau mō ngā Whakaritenga Tiwhikete
Ehara ngā tiwhikete i te rārangi arowhai tūpono noa iho—e ahu mai ana i ngā mātāpono hangarau taketake e pā tika ana ki te mahi me te haumaru o te pūnaha. Whakaarohia ngā momo matua e toru o te whakawhiti wera: te kawe hiko, te whakawhiti wera, me te irahiko. I roto i tePaipa Whakamarumaru Korehauhe ngongo waikura rānei, ka whakakorea katoatia te whakawhiti wera ā-whakawhitiwhiti e te āputa korehau i waenganui i ngā paipa o roto, o waho hoki, ka whakaitihia te turuturu wera katoa mā te neke atu i te 90% ki te whakaritea ki ngā paipa whakamahana tikanga. Ko tēnei whakaiti nui i te urunga wera ka hua tika ki te iti ake o ngā tere kohua, te iti ake o ngā utu whakahaere, me ngā pāmahana tukanga pumau ake.
Heoi, he wero te pupuri i taua korehau i roto i te wā. Ahakoa ngā turuturu iti rawa, ngā hau rānei e puta mai ana i ngā rauemi o roto, ka taea te whakaiti haere i te mahi korehau. Koinei te wāhi ePūnaha Papu Korehau Hihirika whai wāhi mai. He rerekē ki ngā pūnaha korehau korehau e memeha haere ana i roto i te wā, ka tangohia tonutia e tā mātou pūnaha hihiri ngā hau iti mai i te annulus, ka mau tonu te pono o te korehau puta noa i te oranga mahi o te pūnaha. Ko tēnei huarahi kaha ki te whakahaere korehau he rerekētanga matua e mōhiotia ana e ngā rōpū tiwhikete—ā, koinei te take e paahitia tonutia ai e ā mātou pūnaha ngā whakamātautau mahi roa tino pakari.
Ko te whiriwhiri rauemi tētahi atu wāhanga e akiaki ana i te hiranga o te hangarau e ngā whakaritenga tiwhikete. I ngā pāmahana cryogenic, he maha ngā konganuku noa ka pakarukaru, ka ngawari hoki te pakaru. Ka tohua e mātou ngā maitai kore waikura austenitic pēnei i te 304L me te 316L mō ā mātou paipa o roto nā te mea ka mau tonu te pakari me te ātete ki te waikura ahakoa i te -269°C. Ka tīpakohia ā mātou koti o waho i runga i ngā āhuatanga taiao motuhake o te kaupapa—tērā pea me whakanui ake te tiaki waikura mō ngā whakaurunga takutai, ko ngā whakaurunga koraha ia ka whakatairanga i te ātete UV.
Ko te whakaheke wera tētahi atu whakaaro nui. Ina whakamatao te pūnaha whakawhiti cryogenic mai i te pāmahana taiao ki te pāmahana whakahaere, ka tino whakaiti te paipa. Mena kāore i te tika te hoahoa o ngā hononga whānui, ngā piko, ngā wāhanga ngāwari rānei, ka taea e tēnei whakaheke te whakaputa i ngā ahotea whakangaro. Tā tātouNgongo Ngāwari Whakamarumaru KorehauHe mea hanga motuhake ngā hua hei whakauru i ēnei nekehanga, e whakarato ana i te wehenga wera me te ngāwari ā-mīhini i roto i te huihuinga kotahi.
Ngā Taupānga Rohe me ngā Whakatutukitanga o te Ao Tūturu
Ehara ngā whakaritenga tiwhikete kua kōrerotia e tātou i te ariā noa iho—engari e puta ana i roto i ngā kaupapa tūturu i ia rā, i ia rā. Whakaarohia tētahi whakawhānuitanga o te teihana LNG i te Tonga-mā-rāwhiti o Āhia. I hiahiatia he maha ngā mahi mō te kaupapa.Paipa Whakamarumaru Korehaungā pōro, mahaWehewehe Wāhanga Whakamarumaru Korehaungā waeine, me te huinga oTakirere Whakamarumaru Korehaungā huihuinga. I tohua e te kaiwhakatū EPC te tutuki i ngā whakaritenga o te ASME B31.3 mō ngā paipa, te tohu PED CE mō ngā oko pēhanga, me te ISO 21009 mō ngā wāhanga kua whakamahanahia ki te korehau. Nā te mea kei a mātou ngā tiwhikete e toru, i taea e mātou te hanga me te tuku i te pūnaha katoa me te kore e whakaroa i ngā tukanga tiwhikete tuatoru.
I Ūropi, i hiahiatia he pūnaha hauota wai tino ma i tētahi whare hanga haurua-haurua i Āhia ki te Rāwhiti mō tā rātou tukanga hanga. I hiahiatia e te pūnaha kia mau tonu ngā taumata poke iti-ppm me te tuku hauota wai i ngā pēhanga tino whakahaeretia. Ko ā mātou otinga paipa cryogenic me ngā ngongo cryogenic, kua whakamanahia i raro i te PED me te hangaia ki ngā paerewa EN, i tutuki i ā rātou whakaritenga parakore me te pēhanga pakari me te pupuri tonu i te mahi whakamarumaru korehau e tika ana hei whakaiti i te kohua.
Mō ngā kaupapa hauwai i te Middle East, he nui ake ngā tūponotanga. He tino uaua te hangarau i te hauwai wai i te -253°C: ko te rerekētanga pāmahana i waenga i te wai cryogenic me te taiao ātea e tata ana ki te 300°C, ā, ko te iti o te rahi ngota o te hauwai he tino ngāwari ki te turuturu. Mā te tiwhikete i raro i ngā anga ASME me ISO ka whakapumau ka taea e ēnei pūnaha te mahi haumaru i roto i tētahi o ngā taiao tino uaua o te ao.
Whakamutunga: Te Tiwhikete hei Tūāpapa mō te Whakawhirinaki
I roto i te umanga taputapu cryogenic, ehara i te mea ko ngā tiwhikete anake ngā whakaritenga ture—koinei te tūāpapa e hanga ai te whakawhirinaki. Ina whiriwhiria e te kaimahi kirimana EPC tētahi kaiwhakarato, ina tukuna e te kaiwhakahaere hoko he ota hoko, ina tonohia rānei e te kaiwhakahaere tipu he pūnaha whakawhiti hou, ko ngā tiwhikete kei a te kaiwhakarato e whakarato ana i te manatoko whai take, tuatoru mō te kounga, te haumaru, me te pono.
I HL Cryogenics, kāore mātou e titiro ki te tiwhikete hei whakatutukitanga kotahi noa iho. Ka mau tonu ā mātou tiwhikete ASME, CE, me ISO mā te whakapai tonu, ngā arotake auau, me te whakapau kaha tonu ki te hiranga hangarau. Ka horapa tēnei whakapau kaha ki ngā hua katoa e hangaia ana e mātou—mai i te Paipa Whakamātao Korehau me te Ngongo Ngāwari Whakamātao Korehau ki te Takirere Whakamātao Korehau, te Wehewehe Wāhanga Whakamātao Korehau, me ngā otinga Mini Tank. Ahakoa he aha te wero whakawhiti cryogenic, ahakoa kei hea tō kaupapa, kei a mātou ngā tiwhikete, te tohungatanga, me te wheako ki te tuku i tētahi pūnaha e tutuki ana—ā, e hipa ana hoki—i ō hiahia.
Whakapā atu ki a HL Cryogenics i tēnei rā hei matapaki i ngā hiahia tiwhikete motuhake mō tō kaupapa. Kua rite tā mātou tīma hangarau ki te whakawhanake i ngā otinga cryogenic ritenga e tutuki ana i ngā anga ture katoa o te ao.

E harikoa ana mātou ki te whakaae i ngā ota o ngā rahi katoa — mai i ngā kaupapa takitahi ki ngā kaupapa nunui.
Kua hangaia te Paipa Whakamaroke Korehau (VIP) a HL Cryogenics i runga anō i te ASME B31.3 Pressure Piping Code hei paerewa mā mātou.
He kaihanga taputapu korehau motuhake a HL Cryogenics, e tiki ana i ngā rauemi mata katoa mai i ngā kaiwhakarato whai tohu anake. Ka taea e mātou te tiki rauemi e tutuki ana i ngā paerewa me ngā whakaritenga motuhake e tonoa ana e ngā kiritaki. Kei roto i ā mātou whiringa rauemi noa ko te ASTM/ASME 300 Stainless Steel me ngā maimoatanga mata pēnei i te pickling waikawa, te oro miihini, te whakamahana kanapa, me te oro hiko.
Ka whakatauhia te rahi me te pēhanga hoahoa o te paipa o roto i runga i ngā hiahia o te kiritaki. Ka whai te rahi o te paipa o waho i ngā whakaritenga paerewa a HL Cryogenics, ki te kore e tohua tētahi atu e te kiritaki.
Ki te whakatauritea ki te whakamahana paipa tuku iho, he pai ake te whakamahana wera o te pūnaha korehau pao, e whakaiti ana i ngā ngaronga hau mō ngā kiritaki. He iti ake te utu i te pūnaha VI hihiri, e whakaiti ana i te haumitanga tuatahi e hiahiatia ana mō ngā kaupapa.
