I roto i ngā pūnaha paipa nui, ko te hononga haumaru te haurua noa iho o te pakanga. Ko te haurua tuarua ko te whakarite kia tu atu te hononga i ngā kaha mutunga kore o te wiri, te whānui o te wera, me ngā mea waikura. Koinei te wāhi erawhi ngongo rapate whakawhiti mai i tētahi hononga māmā ki tētahi wāhanga nui mō te pumau o te pūnaha.
Ina pā ngā here whakarewa kāore i tiakina ki ngā ngongo ngohengohe, ki ngā taura rānei, ko te mutunga iho he pakaru wawe, he kiripaka, ā, ka pakaru pea. Mā te here ngongo rapa ka whakatauhia tēnei mā te whakatakoto i tētahi arai tiaki i waenganui i te whitiki maitai me te mata o te ngongo, ka mimiti i te ahotea miihini, ka ārai hoki i te pā tika o te whakarewa ki te whakarewa, te whakarewa rānei ki te rapa. Mā tēnei hoahoa māmā engari he tino whai hua ka noho tonu te kaha here me te kore e whakararu i te kounga o te paipa e mau ana.
He aha te Hiranga o te Kōwhiringa Rauemi mō ngā Rawhi Raina Raina Raina
Ko te mahi a te rawhi whakangāwari e tautuhia ana e ōna wāhanga matua e rua: te whitiki whakarewa me te whakaurunga rapa. I Mika (Tianjin) Pipeline Technology Co., Ltd. ka hangaia e mātou ā mātou rawhi kia tutuki ai ngā tono mahi maha, e tuku ana i ngā momo rauemi e rua: W1 me W4.
W1 (Rino Whakarewa):Koinei te kōwhiringa tino pai mō ngā tono paerewa. Ka whakaratohia e te paninga konukōre he paparanga pono o te ātete waikura e tika ana mō te whakamahinga whānui o roto, ngā taiao motuka paerewa, me ngā pūnaha HVAC. Ka tukuna he taurite pai i waenga i te whai huatanga utu me te mahi.
W4 (Kowiri tira 304):Mō ngā tono e pāngia ana e te makuku, ngā matū, te wai tote rānei, ko te maitai kore waikura 304 te kōwhiringa pai rawa atu. Ko tōna ihirangi chromium me te nickel he ātete tino pai ki te waikura me te pakaru, he mea tino pai mō ngā taiao moana, ngā whakaurunga o waho, me ngā wheketere tukatuka matū.
I ngā momo e rua, he mea hanga te urunga rapa mai i te EPDM (Ethylene Propylene Diene Monomer) kounga teitei. He mea whiriwhiri motuhake tēnei rapa hangai mō tōna ātete pai ki te wera, te ozone, te huarere, me te whānuitanga o ngā matū. Ka mau tonu tōna ngāwari me ōna āhuatanga whakamakuku puta noa i te awhe pāmahana tino nui mai i te -40°C ki te 120°C, me te kaha ki te tu atu i ngā pikinga poto tae atu ki te 200°C.
Ngā Āhuatanga Matua e Tautuhi ana i tētahi Rawhi Kounga
Te Whakaiti me te Whakaiti Haruru
Ko te mahi matua o te arai rapa ko te whakaiti i te wiri. I roto i ngā mahi pēnei i ngā pūnaha putanga hau miihini, i ngā mīhini ahumahi taumaha rānei, ka taea e ngā wiri kore e āraihia te wetewete i ngā hononga, ā, ka nui te parahanga haruru. Ka mimiti kaha te whakauru EPDM i ēnei kaha wiri, ka tiaki i ngā wāhanga tairongo, ka hanga he pūnaha marino ake, he pūnaha pakari ake.
Te Tiakitanga me te Āraitanga o te Mata
Ka hangaia e te urunga he atanga kore-whakakawa, ka ārai i te whitiki whakarewa kei tapahi ki roto i ngā ngongo, kei kino rānei te ārai waea. Hei tāpiri, ka whakaratohia e te rapa he paparanga nui o te ārai hiko, ka waiho ēnei here hei whiringa haumaru mō te whakau i ngā taura hiko me ngā taura.
Te Kaha Whakapūmau Haumaru me te Pūmau
Mā te whitiki maitai kaha-teitei, e whakakahangia ana huri noa i te kōhao pūtu, ka mau tonu te kaha o te pupuri o te rawhi. Mā tēnei ka ārai i te paheke i te roanga o te wā, ka mau tonu te pumau o te pūnaha ahakoa i raro i ngā pēhanga rerekē me te huringa wera.
Taupānga puta noa i ngā Ahumahi
Tō mātoungā rawhi ngongo rapahe mea hanga mō ngā tohunga e hiahia ana ki te pono. Nā te maha o ngā whakamahinga ka waiho hei wāhanga nui o te whānuitanga o ngā rāngai.
Waka me te Waka:Te whakapūmau i ngā raina wahie, ngā raina parai, ngā taura waea, me ngā pūnaha whakauru hau.
Te Ope Taua me te Tiaki:Te whakatutuki i ngā whakaritenga pakari mō te pono i roto i ngā āhuatanga pakari, uaua.
Ngā Mīhini Ahumahi:Te whakahaere i ngā pūnaha waipēhi me te hau i roto i ngā taputapu taumaha.
Te Hanganga me te Hanganga:Te whakatika i ngā paipa me ngā paipa hiko i roto i ngā pūnaha HVAC, whakamatao, me te whakamahana.
Moana me te Moana-a-Kiwa:Te tiaki i ngā pūnaha tino nui i roto i ngā taiao tote moana kino.
Ahuwhenua me te Whakamakuku:Te whakarato i ngā hiri haumaru i roto i ngā pūnaha tohatoha wai.
