I te wā e hoko anaPaipa maitai koranu korekore ASTM A335mō ngā tipu hiko, ngā whare whakapai hinu, ngā pūnaha paipa pāmahana-tiketike rānei, he maha ngā wā ka tūtaki ngā kaihoko ki ngā momo tohu rauemi rerekē i roto i ngā whakaritenga o Amerika, Haina, Ūropi me Rūhia.
Ka taea e tētahi kaupapa te tohuASTM A335 P11P22 rānei, i te mea ka taea e te kaiwhakarato ā-rohe te whakahua i ngā utu15CrMo, 15Km, 10CrMo5-5, 10K2K rānei. I te tirohanga tuatahi, tera pea te āhua nei he mea whakawhitiwhiti ēnei momo nā te mea nō ngā whānau maitai koranu chromium-molybdenum rite tonu.
Heoi anō,kāore te hanganga matū ōrite e tohu aunoa i ngā whakaritenga hangarau ōrite.
Mō ngā hokohoko o tāwāhi, ehara i te mea ko "Ko tēhea taumata te rite?" te pātai nui, engari ko te mea mēnā e tutuki ana i ngā rauemi kua whakaarohia ngā whakaritenga o te kaupapa.paerewa, hanganga matū, āhuatanga miihini, maimoatanga wera, whakamātautau me ngā whakaritenga hoahoa.
He aha te ASTM A335?
ASTM A335/A335Mko te whakatakotoranga mōpaipa maitai-konumohe ferritic korekore mō te mahi pāmahana teitei. Kei te rārangi ASTM o nāianei te A335/A335M-26 hei putanga hohe. Kei roto i te whakatakotoranga ētahi momo maitai-konumohe ferritic, tae atu kiP11 me P22, ā, kei roto hoki ngā whakaritenga e pā ana ki te hanganga matū, ngā āhuatanga miihini, te pakeke, te whakamātautau waipūmau me te whakamātautau kore-whakangaro.
Ko te kōwhiringa i waenga i te P11, te P22 me ētahi atu māka e whakawhirinaki ana ki ngā āhuatanga ratonga tuturu me ngā whakaritenga o te kaupapa, kaua ki te ingoa māka anake.
Mō ngā kaihoko, e rua o ngā momo e kōrerohia pinepine ana ko:
●ASTM A335 P11 — pūnaha koranu tata ki te 1.25Cr-0.5Mo
●ASTM A335 P22 — pūnaha koranu tata ki te 2.25Cr-1Mo
Ko te nui ake o te chromium me te molybdenum o P22 ka rerekē te āhua o te mahi pāmahana-tiketike mai i te P11. Ko ngā whakaritenga matū a ASTM e whakarārangi ana i te 1.00–1.50% Cr me te 0.44–0.65% Mo mō te P11, me te 1.90–2.60% Cr me te 0.87–1.13% Mo mō te P22.
ASTM A335 P11 me te 15CrMo / 15HM
ASTM A335 P11e whakamahia whānuitia ana mō ngā paipa pāmahana-tiketike me ngā taputapu wera e pā ana.
I roto i ngā ripanga whakatairite rauemi o te ao, e honoa whānuitia ana a P11 ki te1.25Cr-0.5Mowhānau, tae atu ki10CrMo5-5me te Hainamana15CrMongā tohutoro. Ka whakamahia hoki e ētahi kaiwhakarato me ngā mākete ngā tohutoro ingoa-Rūhia pēnei i15HM, engari me manatoko tonu te kounga me te paerewa hua o Rūhia ki ngā whakatakotoranga o te kaupapa.
Ko te whakaaro nui mō ngā kaihoko, ka rerekē pea te tohu i waenga i tētahi mākete ki tētahi atu, engari he rite tonu te whānau koranu matua.
| Te tohu rauemi | Whānau rauemi noa | Te horopaki hokohoko noa |
| ASTM A335 P11 | Rīra koranu Cr-Mo | Paipa tuitui pāmahana teitei |
| 15CrMo | Rīra koranu Cr-Mo | Ngā tono ahumahi/wera Hainamana |
| 10CrMo5-5 | Rīra koranu Cr-Mo | Tohutoro rauemi Pākehā |
| 15HM | Rīra koranu Cr-Mo | Tohutoro mākete Rūhia/CIS |
Me whakamahi te tēpu heitīmatanga whakatairite, ehara i te mea he ripanga whakakapinga aunoaMe whai te kōwhiringa rauemi whakamutunga i te paerewa me ngā whakaritenga kaupapa e tika ana.
Hei tauira, ka tono te kaihokoPaipa kore-tuitui ASTM A335 P11kaua e whakakapia noa ki te 15CrMo nā te mea he tata te āhua o ngā hanganga matū. Me whakaū te kaiwhakarato i ngā whakaritenga katoa, tae atu ki te āhua o te hua, te maimoatanga wera, ngā āhuatanga miihini, te whakamātautau me ngā tuhinga.
P22 vs 10CrMo5-5 / 10X2M: He aha i hiahia ai kia tiakina te whakataurite
Me aro nui atu ki te whakataurite tuarua.
ASTM A335 P22nō te tata ki te2.25Cr-1Mowhānau. Ko ngā tohutoro Pākehā e honoa ana ki tēnei whānau ko10CrMo9-10 / 10CrMo910, i te mea10X2Mka kitea anō hoki i roto i ngā kōrerorero rauemi Rūhia/CIS.
He rerekē,Ko te 10CrMo5-5 e honoa whānuitia ana ki te whānau konukōre-iti 1.25Cr-0.5Mo, ā, e honoa whānuitia ana ki te A335 P11., kaua ki te P22.
He mea nui tēnei wehewehenga ina whiwhi te tari hoko i ngā whakatau utu mai i ngā whenua rerekē.
Ko te tirohanga whānau-rauemi kua whakamāmāhia koia tēnei:
| Tohu ASTM | Te whānau koranu tata | Ngā tohutoro ā-ao whānui |
| A335 P11 | 1.25Cr-0.5Mo | 15CrMo/ whānau 10CrMo5-5 |
| A335 P22 | 2.25Cr-1Mo | 10CrMo9-10 / 10CrMo910 / ngā tohutoro 10X2M kua tīpakohia |
Nō reira, mēnā e hiahiatia ana he whakaritenga mō tētahi kaupapaASTM A335 P22, me tuku he whakatau utu mō te 10CrMo5-5kāoreme te kore e whakaaetia hei ōrite tika, me te kore he arotake hangarau.
Koinei tonu te wāhi e hiranga ai te kimi rauemi mai i tāwāhi e te hunga mātau:me whai whakaaro ngātahi ki te maha o ngā rauemi, te paerewa hua me te tono kaupapa.
He aha ngā kaihoko e whakataurite ai i ēnei tohu?
He māmā noa te take: he maha ngā paerewa e whakamahia ana i ngā kaupapa o te ao i te wā kotahi.
Ka whakamahia pea e te tipu hiko:
●ASTM A335 P11/P22 mō ngā paipa pāmahana-tiketike
●ASTM A213 T11/T22 mō ngā ngongo pūwero me ngā ngongo whakawhiti wera
●Pereti maitai ASTM A387 Cr-Mo mō ngā oko pēhanga
●Ngongo maitai koranu EN 10216-2
●Ngā tohu GB/T mō ngā taputapu ā-rohe
●Ngā rauemi GOST, ngā rauemi rānei kua tohua ki te Rūhia mō ngā kaupapa CIS
Mō tētahi kaiwhakatū EPC, mā te whakakapi i tētahi rauemi ki tētahi atu ka pā ki:
Hoahoa → Whakarewa → Maimoatanga Wera → Tirotiro → Tuhinga → Whakaaetia
Nō reira, me whakatairite te kounga i mua i te hoko, kaua i muri i te tononga o te rauemi.
P11, P22 rānei: Ko tēhea Tauira me Tauwhāiti e ngā Kaihoko?
Ko te whakautu e whakawhirinaki ana ki ngā āhuatanga whakahaere tuturu.
P11e whakaarohia ana i te nuinga o te wā ina hiahiatia he maitai Cr-Mo iti-koranu e tika ana mō te mahi pāmahana teitei mō te kaupapa.
P22e whakarato ana i te taumata koranu Cr-Mo teitei ake, ā, e whakamahia ana i ngā tono e hiahiatia ana e te whakatakotoranga kaupapa te rauemi e rite ana me te mahi pāmahana teitei.
Ko ngā wāhi tono noa ko:
| Tono | Ngā tauira rauemi |
| Ngā pūnaha kōhua me te mamaoa āwhina | P11 / ngā tohu Cr-Mo e pā ana |
| Ngā paipa mamaoa pāmahana teitei | P11 / P22 i runga i te hoahoa |
| Ngā pane o te tipu hiko | P11 / P22 / ētahi atu tohu kua tohua |
| Ngā paipa tukanga parahanga | P11 / P22 i runga i te ratonga |
| Ngā paipa pāmahana teitei hinu | P22 me ētahi atu tohu Cr-Mo |
| Ngā taputapu pēhanga | Rauemi Cr-Mo motuhake ki te kaupapa |
Me whiriwhiri te māka tika mai i tete pāmahana hoahoa, te pēhanga, te ahotea whakaaetia, te taiao ratonga me te waehere hoahoa e tika ana, kaua mā te whakatairite i ngā utu rauemi anake.
Kāore a ASTM A335 P11 me P22 i rite ki a ASTM A213 T11 me T22
Ko tētahi atu raruraru hokohoko noa ko te whakapoauaungā kōeke paipamengā momo ngongo.
Hei tauira:
●ASTM A335 P11 → paipa maitai-konumohe kore hononga mō te mahi pāmahana teitei
●ASTM A213 T11 → te kohua korekore, te wera nui me te ngongo whakawhiti wera
●ASTM A335 P22 → paipa maitai-konumohe kore hononga
●ASTM A213 T22 → hua ngongo mō ngā tono e hipokina ana e A213
He hononga kei roto i te whānau koranu Cr-Mo i ngā tohu P11/T11 me P22/T22, engari he rerekē ngā paerewa hua.
He mea nui tēnei rerekētanga ina whakarite ana i tētahi ota hoko, nā te meatohu + paerewa hua + ine + whakaritenga whakamātautaume tutuki katoa ngā whakaritenga o te kaupapa.
He aha ngā mea me tirotiro e ngā kaihoko i mua i te tono?
I te wā e hoko anaPaipa ASTM A335 P11 or Paipa ASTM A335 P22, kāore pea e ranea tētahi patai poto pēnei i te "paipa P11, tēnā whakahuahia mai he aha te utu".
