Whakamāramatanga:paipa maitai pāmahana itihe waengamaitai hanganga waroHe pai te mahi a ngā paipa maitai makariri, wera, me te pāmahana iti, he pai ngā āhuatanga miihini, he iti te utu, ā, he whānui ngā pūtake, nō reira he whānui te whakamahinga. Ko tōna ngoikoretanga nui ko te kore e tika kia whakamahia ngā wahi mahi he iti te pakeketanga, he nui te rahi o te wāhanga, ā, he nui ngā whakaritenga.
Tepaipa maitai kore-mahana itiKa taea te mahi i roto i te taiao tino makariri o -45~- 110 ℃. Ko te painga nui o te paipa maitai kore-ira pāmahana iti ko tōna kaha ki te mahi i roto i te taiao tino iti, he mea kāore e taea te whakarite ki te paipa maitai kore-ira noa. He kaha pai te paipa maitai kore-ira pāmahana iti, ā, he pakari pāmahana iti, ā, he whānuitia te whakamahinga i roto i te hanga taputapu pāmahana iti i roto i te hinu, te matū, te tongi me ētahi atu ahumahi me te pāmahana mahi o -45~- 110 ℃. I te whanaketanga o ngā ahumahi e tika ana, ko ngā whakaritenga mō ngā rauemi kāore i te herea noa ki ngā whakaritenga taketake pēnei i ngā āhuatanga miihini me ngā āhuatanga whakarewa, engari me ngā whakaritenga mō te ātete ki te waikura H2S o ngā paipa pāmahana iti.
Paipa maitai kore-pāmahana itie pā ana ki te hangarau paipa i roto i te taiao pāmahana iti. E rua ngā tukanga: te kukume makariri me te hurihuri wera. Mai i te tirohanga a te hoahoa maitai, me tino whakahaere te hanga maitai, te hurihuri, te maimoatanga wera me ētahi atu tukanga o te paipa maitai kore-ira pāmahana iti kia pai ai te kaha, te pakari me te ātete ki te waikura o te paipa maitai kore-ira pāmahana iti. Mō ngā whakaritenga hangarau o te paipa maitai kore-ira pāmahana iti, me whai whakaaro whānui ki te whakahaere whakaputa me te utu whakaputa o te paipa maitai. Me whakarite te hoahoa hanganga o te paipa maitai kore-ira pāmahana iti kia tika te kaha o te hua, kia teitei te pakari pāmahana iti, me te tukanga maimoatanga wera watea. He pai te kaha whakarewa me te ātete ki te pakaru i puta mai i te hauwai.
Paerewa whakahaere o te paipa maitai kore-mahana itiASTM A333- Paipa Rino Tuitui me te Whakarewa mō te Ratonga Pāmahana-Iti
Rauemi pāmahana-itipaipa maitai kore-tuituihua: 16Mn, 10MnDG, 09DG, 09Mn2VDG, 06Ni3MoDG, me ētahi atu.
