Paipa maitai koranu kore-tuitui A335P92, whakatakotoranga 48.3*7.14 (arā, te diameter o waho 48.3mm, te matotoru o te pakitara 7.14mm), hei paipa pēhanga teitei, ko tōna paerewa whakatinanatanga ko ASTM A335M. Anei tētahi tātaritanga taipitopito o te paipa maitai:
I. He tirohanga whānui mō ngā Ngongo Pūwero Rino
Ko te paipa maitai koranu kore-ira A335P92 he momo paipa maitai koranu kore-ira kounga teitei, he pāmahana teitei, he pēhanga teitei hoki, e whakamahia whānuitia ana i roto i ngā taiao pāmahana teitei me te pēhanga teitei pērā i te paipa mamaoa matua me te paipa mamaoa whakamahana anō o ngā tipu hiko wera. Ko tōna rauemi he P92, nō te nama maitai ātete wera martensitic o te United States ASTM A335 P92.
Tuarua, te hanganga matū o ngā Ngongo Kohua Rino
Ko te hanganga matū o ngā paipa maitai koranu A335P92 he mea tino tika te whakahaere, tae atu ki te waro, te konupūmā, te whākōkī, te whanariki, te silicon, te chromium, te molybdenum, te vanadium, te hauota, te nickel, te konumohe, te niobium, te tungsten me te boron me ētahi atu huānga. Ko te whānuitanga o ngā ihirangi motuhake koia ēnei:
Waro (C): 0.07~0.13%
Manganēhi (Mn) : 0.30-0.60%
Whēkau (P) : ≤0.020%
Whānariki (S) : ≤0.010%
Hiraka (Si) : ≤0.50%
Konukōmiuma (Kr): 8.5~9.50%
Molybdenum (Mo): 0.30~0.60% (engari he mea tika kia mōhiotia, ki te whakatauritea ki te maitai SA-335P91, ka whakaitihia e te maitai SA-335P92 te nui o te huānga Mo, ā, ka whakapai ake i te mahi a te rauemi mā te tāpiri i tētahi nui o te W)
Vanadium (V): 0.15~0.25%
Hauota (N) : 0.03~0.07%
Nikara (Ni) : ≤0.40%
Konumohe (Al) : ≤0.04%
Niobium (Nb) : ≤0.040~0.09%
Tungsten (W): 1.5~2.0%
Pūtoru (B) : 0.001~0.006%
Nā te ōwehenga whaitake o ēnei huānga, he pai rawa atu te ātete ki te waikura pāmahana teitei, te ātete ki te waikura, te kaha pāmahana teitei me ngā āhuatanga ngokingoki o te paipa maitai koranu A335P92.
3. Ngā āhuatanga hangarau o ngā ngongo koiri rino
He tino pai ngā āhuatanga hangarau o te paipa maitai kore-whakauru A335P92, e whakaaturia ana i raro nei:
Kaha kume: ≥620MPa
Kaha whakaputa: ≥440MP
Mā ēnei āhuatanga hangarau ka whakarite te haumaru me te pono o ngā ngongo maitai i roto i ngā taiao pāmahana teitei me te pēhanga teitei.
4. Mara tono o ngā Ngongo Kohua Rino
Nā te pai o ngā āhuatanga mahi, he pai rawa te whakamahi i te paipa maitai koranu A335P92 i roto i ngā mara e whai ake nei:
Te tipu hiko wera: hei rauemi matua mō te paipa mamaoa matua me te paipa mamaoa kua whakamahanahia anō, ka taea e ia te tu atu i te pāmahana teitei me te pehanga teitei hei whakarite i te mahi haumaru o te tipu hiko.
Matū matū: I roto i te tukanga whakamahine hinu me te whakaputa matū, ka whakamahia hei hanga taputapu pēnei i ngā tauhohenga, ngā whakawhiti wera me ngā paipa tuku hei whakatutuki i ngā whakaritenga o te pāmahana me te pēhanga teitei me te ātete ki te waikura.
Te umanga pūngao karihi: I roto i ngā tipu mana karihi, e whakamahia ana hei hanga i ngā pūnaha whakamatao tauhohenga karihi me ngā paipa e pā ana hei whakarite i te haumaru me te pumau o te whakaputa mana karihi.
5. Ngā paerewa whakatinanatanga me ngā tohutohu tono mō ngā Ngongo Kohua Rino
E tutuki ana te paipa maitai kore-ira A335P92 i te paerewa matua ASTM A335/A335M. Me mārama ngā mōhiohio e whai ake nei i te wā e tono ana:
Te rahinga (hei tauira, i roto i ngā putu, mita, pakiaka rānei)
Ingoa rauemi (paipa ingoa maitai koranu kore-tuitui)
Akomanga (P92)
Tikanga hanga (whakaoti wera, tuhi matao rānei)
Ngā Whakatakotoranga (hei tauira, te whānui o waho, te matotoru o te pakitara, me ētahi atu)
Te roa (rahi wehea me te rahi rerekē)
Te miihini mutunga
Ngā whakaritenga kōwhiringa (hei tauira, te pēhanga wai me te rerekētanga taumaha e whakaaetia ana)
Pūrongo whakamātautau e hiahiatia ana
Tau paerewa
Ngā whakaritenga motuhake, ngā whakaritenga tāpiri rānei
Hei whakarāpopototanga, ko te paipa maitai kore hononga koranu A335P92 he paipa maitai kore hononga koranu kounga teitei, he pāmahana teitei, he pēhanga teitei hoki, e whakamahia whānuitia ana i roto i ngā mara maha me ōna āhuatanga mahi tino pai. I te wā e tono ana, e whakamahi ana hoki, me tino tutuki ngā paerewa me ngā whakaritenga e tika ana kia mau ai tōna haumaru me tōna pono.
