Mō ngā paipa whakamātao korehau, kāore he mea e rite ana ki te whakamātautau turuturu o te inenga papatipu helium. He tairongo tēnei tikanga ki te kite i ngā turuturu iti rawa—tae atu ki te 5×10⁻¹³ mbar·L/s. Heoi, kāore mātou e mutu i reira. Ka tautokohia tēnei e mātou mā te whakamātautau pikinga pēhanga tūmau, kia kite ai mātou i te tere o te pirau o te korehau i roto i te wā. Pērā ai, ka taea e mātou te kite i ngā turuturu me te tirotiro i te pono o te pūnaha katoa i te wā kotahi. Heoi anō, ko te tirotiro māmā rawa te mea tuatahi: tirohia noa mēnā he hukapapa kei te koti o waho. Me mōhio ia kaiwhakahaere he tohu whakatūpato wawe pea te wāhi hukapapa. Ā, mō ngā pūnaha pēhanga, he pai te kimi turuturu ultrasonic. Ka kitea ngā turuturu mai i te tawhiti o te 50 putu.
I HL Cryogenics, ka whakamahia e mātou ēnei tikanga katoa, me te piripono ki ngā paerewa ASME, CE, me ISO. Ahakoa hePaipa Whakamarumaru Korehau, heNgongo Ngāwari Whakamarumaru Korehau, he Tank Iti rānei, ka puta mai ia hua i roto i tō mātou whare me te tutuki i ngā whakaritenga tino ārai-taupoki, ā, kua rite mō te mahi i ngā wāhi katoa o te ao.
Kāore te whakawhiti wai cryogenic e muru i ngā hapa. Whakaarohia: kei te whakahaere koe i te hauota wai i te -196°C, i te LNG rānei i te -162°C mā roto i te paipa i te wā e rite ana te hau i waho ki te pāmahana rūma. He nui te āputa pāmahana—neke atu i te 250°C. Ahakoa he kōhao iti e tuwhera ana i roto i te paparanga korehau, ka uru te hau ki roto. Kātahi ka huri aua ngota hau hei piriti wera iti, ka pakaru te whakamarumaru. Ka piki ake te turuturu o te wera, ka tere ake te kohua o te hua, ā, ka nui te utu—ina koa i ngā teihana LNG i te Tonga-mā-rāwhiti o Āhia, i reira ka taea e te kotahi noa te takai pakaru te moumou mano tāra o te hua i ia rā.
Engari he hohonu ake ngā mōrearea i te moni. Kua tuhia e te Rōpū Hau Ahumahi o Ūropi ngā take i puta ai ngā turuturu o roto i ngā tāke kua whakamahanatia ki te korehau. Whakaarohia tēnei: ka puta he kapiti ngenge i roto i te whakarewa, ka mimiti te wai cryogenic ki roto i te wāhi korehau, ā, ka tino makariri te uhi o waho ka pakarukaru. Ina pakaru, ka pupuhi mai ngā wahi maitai me te kaha whakamate. He rite tonu te mekameka o ngā mahi, ā, he morearea tonu. Ko te kite wawe i ēnei raruraru ehara i te mea he mea pai noa iho - he mea tino nui mō te haumaru.
Rārangi Kaupapa

Tikanga 1 me te 2: Tirotiro Tirohanga me te Kitenga Hukapapa
Kāore koe e hiahia ki ngā taputapu papai mō te tikanga kimi tino taketake me te pono - engari ko ngā tāngata pūkenga e mōhio ana ki ngā mea hei rapu. Ina hePaipa Whakamarumaru KorehauKi te kore rānei e ngaro te ārai o te Tank Iti, ka tere te mātao o te rohe e karapoti ana i te turuturu. Mēnā he nui te mātao ka tau te makuku o te hau, ka tio, ā, ka puta he papa hukapapa ki te koti o waho. Ka kitea nuitia tēnā, inā koa i te taha o te toenga o te paipa i te pāmahana rūma.
Ka whakaaturia tonutia e mātou ki ngā kaiwhakahaere o ā mātou kiritaki te mahi i ēnei tirotiro ā-kanohi i ia wā, i ia wā. Ka arotahi rātou ki ngā mea e kitea ana: ngā whakarewa, ngā flanges, ngā takirere, me ngā hononga. Ki te kite tetahi i te hukapapa, i te hukapapa rānei i waho o te koti—me te kore e kitea he turuturu wai—he tohu whero tonu tēnā. Ko te tikanga, kati, whakatangihia te whakaoho, ka tīmata i tētahi tirotiro tātaritanga katoa. Nā tēnei huarahi māmā kua mutu te maha o ngā aituā i mua i te pikinga ake. He mea noa tēnei i roto i ngā mahi hau ahumahi o Ūropi me ngā tipu haurua-ā-rāwhiti o Āhia, he mea kāore e taea te whiriwhiri i te whai i tētahi tuku LN₂ tonu.
Mā te whakamātautau pikinga pēhanga tūmau ka mōhio koe mēnā kei te mau tonu te korehau i roto i te pūnaha cryogenic, engari kāore e whakaatu tika ana kei hea te turuturu. He māmā noa te tukanga: hiritia te porowhita korehau, honoa he ine korehau kua whakatikatikaina, ā, mātakitaki me pēhea te huri o te pēhanga i roto i te wā.
Mā ngā Takirere Whakamarumaru Korehau, ngā Wehewehe Wāhanga rānei, ka whakahaerehia e mātou tēnei whakamātautau mō ngā haora 24, ka tīmata mai i te pēhanga i raro i te 1×10⁻³ Pa. Mēnā ka piki ake te pēhanga i te rohe kua whakaritea—e whakatakotoria ana e te ISO 20486, e te ASTM E1603 rānei—he tohu tēnā kei te turuturu, kei te nui rānei te hau e puta mai ana i roto. He tairongo tēnei whakamātautau—tae atu ki te 1×10⁻¹² Pa·m³/s—nō reira ka taea te wero, ahakoa mō ngā kaupapa hauwai i te Middle East me ā rātou paerewa turuturu tino pakari.
Tikanga 3: Whakamātautau turuturu o te Ine Pānga Hīriama
Ko te whakamātautau turuturu o te inenga papatipu helium te paerewa koura mō te kimi me te ine i ngā turuturu i roto i ngā pūnaha whakamahana korehau. He take māmā noa iho tā mātou e whakawhirinaki ana ki te helium: koinei te ngota hau iti rawa. Ka uru puku atu i roto i ngā turuturu iti e kore e taea e ētahi atu hau te tae atu, engari kāore e tauhohe ki ngā taputapu, e whakakino rānei i te wai cryogenic.
Koinei te mahi a te tukanga. Ka tīmata mā te kukume i te korehau ki roto i te porowhita, me te pupuri tonu i te ine papatipu kia mono ki te putanga korehau. Kātahi ka neke atu mā te pupuhi poto o te herium, ka rehuhia ki ngā wāhi katoa e whakapaetia ana—ngā hononga whakarewa, ngā hononga, ngā hononga, me ngā pūwāhi hononga i runga i tePaipa Whakamarumaru Korehau, Ngongo Ngāwari, me ngā huihuinga takirere. Ahakoa he turuturu iti rawa kei reira, ka kitea e te hēriuma. Ka paheke te hau ki te wāhi korehau, ka hongihia e te ine hiko, ā, ka puta tonu he tohu whakaoho.
Me whakamahi i tētahi atu rautaki mō ngā turuturu o roto. Engari ko te rehu, ka utaina e mātou te heriuma ki roto i te paipa o roto, ka pēhia. Mēnā ka puta mai tētahi mā roto i tētahi kōhao iti e kore e kitea ki roto i te āputa korehau, ka kitea tonutia e te taputapu kite te tohu. Mā te whakawhiti i waenga i tēnei tikanga "rehu" me te whakamātautau "pēhanga", kāore mātou e waiho i tētahi ara kia kore e tirohia—ki roto, ki waho rānei.
Ka piri tonu mātou ki ngā paerewa pakari o te ASME Standard V, te Tuhinga 10, me te Apitihanga IV me te V. Mā tēnei huarahi ka taea e mātou te kite i ngā turuturu ki raro ki te 5×10⁻¹³ mbar·L/s—he taumata e kore e taea e ētahi atu tikanga te taurite.
Tikanga 4: Te Kitenga i te turuturu Ultrasonic
Ka noho te kimi i te ultrasonic hei taputapu whai hua hei hoa mō te whakamātautau helium i roto i te tirotiro tere o ngā pūnaha pēhanga cryogenic. Ka puta mai ngā tukunga oro ultrasonic i roto i te pūnaha pēhanga nā te rere o te wai. Nō reira, mā te whakamahi i tētahi taputapu kite ultrasonic kawe, ka taea e ngā tohunga hangarau te kite i ngā turuturu i roto i ngā paipa, tae atu ki ngā huihuinga uaua pērā i te Ngongo Ngāwari Whakamātao Korehau me ngā ngongo cryogenic me te kore e whakararuraru i ngā mahi o te pūnaha.
Ka tino whai hua tēnei tikanga ina kitea ngā turuturu i roto i ngā whakaurunga e hiahia ana kia whakahaerehia tonutia, pērā i ngā mea e pā ana ki ngā whakaurunga LNG, ki ngā tipu hau ahumahi rānei. Tae atu ki te 50 putu te tawhiti mai i te pūwāhi turuturu ka taea e ngā tohunga hangarau te kite i te wāhi o te turuturu i roto i te whakaurunga, ka tere ake, engari he iti ake te tairongo o te whakamātautau i te ine papatipu helium.
Heoi, ehara i te mea ko te kimi turuturu te mutunga o te kōrero – ko te aukati i ngā turuturu te whāinga matua o te hangarau. HL Cryogenics'Paipa Whakamarumaru Korehaume ngā Tāke Iti he maha ngā whakatūpato e aro ana ki te tiaki i te pirau o te korehau.
Ko te āhuatanga matua o ngā pūnaha korehau a HL Cryogenics ko tePūnaha Papu Korehau Hihiri, e whakamana ana i te tiaki i te pono o te korehau i ngā wā katoa e whakamahia ana ngā taputapu. He rerekē ki ngā pūnaha korehau tuku iho e pāngia ana e te hekenga haere o te korehau nā te putanga mai o te hau o roto o ngā rauemi, ka tangohia tonutia e tā mātou pūnaha ngā hau toenga mai i te porowhita, ka tiakina te pai o te whakamarumaru korehau kia iti iho i te 1×10⁻³ Pa. Mā te tiaki hihiri ka roa ake te ora o ngā taputapu.
He mea nui anō hoki te whiriwhiri rauemi tika. Ko ngā maitai kore waikura austenitic anake (304L me te 316L) ka whakamahia e mātou, e whakamana ana i te pakari me te ātete ki te waikura i ngā pāmahana cryogenic o te -269°C. Ko ā mātou whakarewa katoa he mea hanga kia rite ki ngā whakaritenga o te ASME Wāhanga IX, ā, ka tirohia ia mea mā te whakamātautau radiographic, te whakamātautau dye-insert rānei i mua i te whakamātautau korehau. Kua whakamanahia ā mātou hua e ASME, CE me ISO, e āhei ai te whakaputa hua kia rite ki te paerewa o tētahi whenua – ahakoa he tutukitanga PED mō ngā mākete Pākehā, ASME B31.3 mō ngā teihana LNG o Amerika, GB/T 18442 rānei mō ngā hau ahumahi Hainamana.
Whakataunga
Hei tauira, he kaupapa hou tēnei mō tētahi teihana whakahou hau LNG i te Tonga-mā-rāwhiti o Āhia. Neke atu i te 200 mita oPaipa Whakamarumaru Korehau, ētahi huihuinga takirere ārai korehau, me ētahiNgongo Ngāwari Whakamarumaru KorehauI hiahiatia kia tāutahia ngā hononga mō te whakawhiti mai i te kaipuke ki uta. Ko te taahiraa tuatahi o tā mātou tikanga kimi turuturu ko te whakamātautau i te ine papatipu herium o ngā whakarewa me ngā hononga katoa i roto i tā mātou awheawhe, i mua i te tukunga o ngā taputapu ki te papaanga.
Ko te taahiraa tuarua ko te whakamātautau anō i te papaanga mā te whakamahi i te whakamātautau ine papatipu helium me te whakamātautau ultrasonic. I roto i te mahi whakamutunga, i kitea e ngā tohunga hangarau he tohu oro rerekē mai i te hononga flange, kua tirohia ā-kanohi i mua. I whakaatuhia e te whakamātautau helium he turuturu iti iho i te 1×10⁻⁸ mbar·L/s, ka heke te mahi whakamahana korehau i roto i ngā marama torutoru o te mahi i muri mai. Whai muri i tā mātou whakatikatika i te hiri flange me ngā whakamātautau anō, i manatokohia te pūmau o te turuturu. Ināianei, e toru tau te roa o te mahi a te tauranga, me te kore he pakaru o te korehau.
Nō reira, ehara te kimi turuturu i roto i ngā paipa korehau i te hangarau kotahi, engari he tukanga hangarau matatini e whakakotahi ana i te tirotiro tirohanga, te whakamātautau pikinga pehanga, te whakamātautau ine papatipu herium me te tirotiro ultrasonic.
Kua whakauruhia ēnei tikanga whakamātautau katoa ki roto i te tukanga QA i HL Cryogenics, nō reira, ko iaPaipa Whakamarumaru Korehau, Ngongo Ngāwari Whakamarumaru Korehau, Takirere Whakamarumaru Korehau,Wāhanga Wehewehenga Whakamarumaru KorehauKo te r, me te Mini Tank e tukuna ana e mātou e tutuki ana i ngā paerewa kounga teitei o te ao. Mai i te teihana LNG i te Tonga-mā-rāwhiti o Āhia ki te tipu haurua-ira i te Rāwhiti o Āhia, mai i te tipu hau ahumahi i Ūropi ki te tipu hauwai i te Waenganui Rawhiti—ahakoa he aha tāu kaupapa, kei a mātou kaihangarau te tohungatanga me ngā tohu mātauranga (ASME, CE, me te ISO)—hei whakarato ki a koe he pūnaha cryogenic kounga teitei, ātete-rerenga.
Whakapā mai ki a HL Cryogenics inaianei, ka whakamōhio mai ki a mātou he aha ngā mea e hiahiatia ana e tō kaupapa e pā ana ki te kimi turuturu. Mā tā mātou tīma hangarau e whakawhanake te tikanga whakamātautau turuturu e hiahiatia ana mō tō pūnaha cryogenic anake!
