Whakamōhio mai:
I te ao o ngā paipa rino,paipa porowhita kua whakarewainaHe rongonui tēnei paipa mō tōna kaha, tōna whānui, me tōna whai huatanga. He whānuitia te whakamahinga o ēnei paipa i roto i ngā momo ahumahi pēnei i te hinu me te hau, te tuku wai, te hangarau hanganga me te whanaketanga hanganga. Hei whakarite i te whakaurunga pai me te mahi tino pai, he mea nui kia mārama ki ngā whakaritenga e whakahaere ana i te paipa porowhita kua whakarewahia. I roto i tēnei tuhinga, ka rukuhia e mātou ngā āhuatanga matua o ngā whakaritenga paipa porowhita kua whakarewahia, me te whakamārama i ō rātou rahi, ngā rauemi me ngā whakaritenga motuhake.
1. Rahi o te paipa:
He maha ngā rahi o ngā paipa whakarewa porowhita, kia taea ai te whakamahi ki ngā kaupapa rerekē. Ko ngā rahinga ko te diameter o waho (OD), te matotoru o te pakitara (WT), me te roa. Ko ngā diameter o waho kei waenga i te 20 inihi ki te 120 inihi, ā, ko ngā matotoru o te pakitara kei waenga i te 5 mm ki te 25 mm. Mō te roa, ko ngā wāhanga paerewa noa o ngā paipa whakarewa porowhita he 6 mita, 8 mita, me te 12 mita hei urutau ki ngā whakaritenga hangarau.
2. Ngā Rauemi:
He mea nui te whiriwhiri i te rauemi o ngā paipa SSAW, ā, e whakawhirinaki ana ki te whakamahinga e hiahiatia ana me ngā āhuatanga taiao. E whakamahia whānuitia ana te maitai waro mō tōna kaha, tōna roa, me tōna ātete ki te waikura. Hei tāpiri, mō ngā whakamahinga motuhake e hiahia ana kia kaha ake te ātete ki te waikura, ki te ātete rānei ki te pāmahana teitei, ka taea te whakamahi i ngā paipa i hangaia ki te maitai koranu, ki te maitai kore waikura, ki ētahi atu rauemi motuhake rānei.
3. Tukanga hanga:
Ka hangaia te paipa whakarewa porowhita mā te tukanga hanga porowhita tonu mā te whakamahi i ngā koiri rino. Mā tēnei tikanga ka whakarite kia ōrite te matotoru o te pakitara, te whānui me te hanganga whānui. Ka whāngaihia te koiri ki roto i te mīhini, ka hangaia ki te āhua porowhita e hiahiatia ana, kātahi ka whakarewahia ngā taha. Mā ngā hangarau matatau e whakamahia ana i roto i te tukanga hanga ka taea te whakahaere tika i te rahi me te mahi o te paipa whakamutunga.
4. Ngā paerewa kounga:
Hei whakatutuki i ngā paerewa ahumahi, hei whakarite hoki i te pono o ngā paipa whakarewa porowhita, he maha ngā tikanga whakapūmau kounga kua whakatinanahia. Kei roto i ēnei ko te tutuki i ngā paerewa o te ao pēnei i te API 5L, ASTM A252 me te ISO 3183-3. Mā te tutuki i ēnei whakaritenga ka whakamanahia ngā āhuatanga ā-pūkaha, te hanganga matū, me te tika o ngā āhuatanga o te paipa.
5. Te whakamātautau me te tirotiro:
Hei whakarite i te pono me te haumaru o te mahi a te paipa porowhita kua whakarewaina, me tino whai i ngā tikanga whakamātautau me te tirotiro. Whakamahia ngā tikanga whakamātautau kore-whakangaro pērā i te whakamātautau ultrasonic, te whakamātautau radiographic me te whakamātautau werohanga tae. Ka kitea e ēnei whakamātautau ngā hapa hanganga, ngā rerekētanga rauemi rānei ka pā ki te mahi me te roa o te paipa. Hei tāpiri, ka mahia ngā whakamātautau ā-tinana pērā i te whakamātautau hydrostatic hei aromatawai i te kaha me te kaha o ngā paipa ki te pupuri i te pēhanga.
Hei whakamutunga:
He maha ngā painga o ngā paipa whakarewa porowhita i runga i ētahi atu momo paipa, ā, he mea nui ngā whakaritenga ki te pupuri i te kounga, te pono me te hototahi ki ngā tono rerekē. He mea nui te mārama ki ngā ine, ngā rauemi, ngā tukanga hanga me ngā paerewa kounga e pā ana ki te paipa whakarewa porowhita kia pai ai te mahi me te otinga utu-whai hua. I te haere tonu o te whanaketanga o te hangarau, ka haere tonu te whakapai ake i ngā whakaritenga e whakahaere ana i ēnei paipa, ka piki ake te pai me te whānui o te whakamahinga i roto i ngā momo ahumahi. Mā te whakaaro ki ēnei whakaritenga, ka taea e ngā miihini me ngā tohunga ngaio te whakatau whai whakaaro mō te whiriwhiri me te whakamahi i te paipa whakarewa porowhita mō ā rātou kaupapa.
