Kupu Whakataki
I te mea kei te whakapai tonuhia ngā ahumahi tūhura me te whakamahine hinu me te hau i te takutai moana o Caspian, kei te piki haere te hiahia mō ngā paipa e kaha ana ki te tu atu i te pāmahana teitei, te pēhanga teitei me te waikura whanariki i ngā kaupapa kohikohi me te whakamahine i raro i te wai. I raro i ngā āhuatanga whakahaere tino kino, ka ngawari te pakaru o te waikura, te whakarerekētanga ngoki me te pakaru o te ahotea whanariki i ngā paipa maitai waro noa, ā, kāore e taea te whakarite i te haumaru whakahaere mō te wā roa.
ASTM A335 P9kōromi-moripaipa koranu kore-tuituiKo te ngongo koranu ferritic te paerewa mō te ratonga pāmahana teitei me te pēhanga teitei. E aro ana ki ngā āhuatanga o te tere rere nui, te pēhanga teitei me te reo kawa i roto i ngā kaupapa hinu me te hau o Azerbaijan, e whakarato ana a SANONPIPE660 mm te whānui o waho, 20 mm te matotoru o te pakitaraHe paipa matotoru, he kore hononga, he A335 P9. I hangaia kia rite ki ngā paerewa ASTM, ā, ka taea te whai i ngā whakaritenga hangarau o te ao, he pai hei "toto toto" kawe wai pono mō ngā kaupapa hangarau hinu me te hau o te rohe o SOCAR.
ASTM A335 / ASME SA335Ko te paerewa paerewa tēnei mō ngā paipa maitai koranu ferritic kore hononga e hangaia ana mō te mahi pēhanga teitei i te pāmahana teitei. Hei te taumata matua i roto i te raupapa 9Cr-1Mo, ka eke a P9 ki ngā whakapainga mahi e toru i roto i te ātete wera, te ātete waikura me te ātete ngoki mā te whakataurite tika o te chromium me te molybdenum.
Te Hanganga Matū Matua me ngā Mahi
| Huānga Whakakotahi | Awhe Ihirangi | Mahi Whakamahi |
|---|---|---|
| Konukōmiuma (Kr) | 8.0% – 10.0% | Ka hanga he paparanga tiaki chromium oxide mātotoru, whakaora-ake i runga i te mata o te paipa, ka whakapai ake i te ātete ki te waikura pāmahana teitei me te ātete ki te waikura whanariki, e tika ana mōpāpāho hinu me te hau kawa |
| Molibdenuma (Mo) | 0.90% – 1.10% | Ka whakarei ake i te kaha o te pāmahana teitei me te ātete ngoki mā te whakapakari i te otinga totoka, ka ārai i te huringa me te pakaru o te paipa i raro i te pāmahana me te pēhanga teitei mō te wā roa. |
Ngā Āhuatanga Mīhini Matua
- Te kaha kume iti rawa:415 MPa
- Te kaha hua iti rawa:205 MPa
- Te pāmahana ratonga tonu mōrahi:≤ 650°C
- Te tutuki i ngā whakaritenga rauemi: Te tutuki i ngā whakaritengaNACE MR0175ngā whakaritenga mō te ātete ki te pakaru o te ahotea whanariki, e tika ana mō ngā taiao hinu kawa me te hau waikawa
Ki te whakaritea ki te maitai waro noa, he roa ake te ora pakaru o te paipa koranu P9 i roto i te awhe 500–600°C, ā, koinei te rauemi pai mō ngā waeine whakamahine pāmahana teitei me ngā paipa mamaoa pēhanga teitei.
Ngā Kaupapa Matua mō te Rāngai Hinu me te Hau o Azerbaijan
E rite ana ki ngā āhuatanga o te hau kawa e pā ana ki te hinu me ngā pāmahana teitei o te tukanga whakamahine i ngā mara hinu o Azerbaijan, ka kapi katoa ngā paipa A335 P9 660×20 i ngā āhuatanga mahi matua puta noa i te mekameka uara o runga, o waenga me te o raro.
1. Te Kohikohi me te Tukatuka Hinu me te Hau o Runga
Mō ngā paipa kohikohi hinu kawa me te hau pāmahana teitei i ngā mara hinu o uta me waho o Caspian,Paipa koranu A335 P9Ka ātete ki te waikura waikawa me te pehanga roa. Ka urutau te diameter nui 660 mm ki ngā whakaritenga tuku rere nui o ngā raina takere, he mea pai rawa atu mō ngā paipa tukatuka pāmahana teitei i roto i ngā taunga kohikohi me ngā teihana whakanui.
2. Ngā Wāhanga Tukatuka Whakamahi me te Petrochemical
I roto i ngā wāhanga matua o ngā whare hanga hinu SOCAR pērā i te pakaru catalytic, te hydrodesulfurization me ngā whakamahana whakahou, ka whakamahia whānuitia ngā paipa koranu P9 i roto i:
- Ngā ngongo oumu me ngā aho whakawhiti pāmahana-tiketike
- Ngā paipa tomo me te putanga o ngā tauhohenga hauwai
- Ngā paipa reo kawa pāmahana-tiketike i roto i ngā waeine desulfurization
Mā tōna ātete pai ki te hauwai me te waikura whanariki ka taea te whakaiti i te kati o te tipu me te auau o ngā mahi tiaki.
3. Ngā Pūnaha Whakaputa Hiko me ngā Pūnaha Whaipainga
I roto i ngā tipu hiko herehere me ngā pūnaha poihau wera para e tautoko ana i ngā whare whakapai hinu, ka whakamahia ngā paipa maitai P9 ki ngā wāhanga whakamahana nui me ngā wāhanga whakamahana anō me ngā raina mamaoa matua, kia mau tonu ai te pumau hanganga mō te wā roa i raro i ngā āhuatanga mamaoa akomanga 600°C, me te whakarite hoki kia mahi tonu ngā pūnaha whaipainga.
Te Uara Hangarau o te Whakatakotoranga Rahi 660×20 mm
Te kōwhiringa o660 mm OD × 20 mm WTKo te whakatakotoranga e hangai ana ki ngā whakaaro hangarau whānui o ngā tikanga mahi rere-rahi, te haumaru pehanga me te āheinga waikura.
Te Diameter Nui mō te Tuku Rere-Tiketike
Ko te hoahoa whānui o roto, 660 mm te whānui, e tutuki ana i te hiahia tuku wai pāmahana teitei e rere nui ana i ngā raina matua o te whare whakapai hinu me ngā pane kohikohi mara hinu, e whakaiti ana i te ngaronga pēhanga o ngā paipa, e whakapai ake ana i te pai o te tuku pūnaha, ā, e urutau ana ki te tauine kaha o ngā kaupapa whakauru whakapai hinu nui.
Te Hoahoa Pakitara Taumaha mō te Pūngao Pēhanga me te Ora Ratonga Taumaha
E toru ngā paparanga o te uara hangarau e tukuna ana e te hoahoa pakitara matotoru 20 mm:
- Te whakapumautanga o te pehanga: E tutuki ana i ngā whakaritenga pēhanga mahi i runga ake i te 9.8 MPa i ngā pāmahana teitei me te tauwehenga haumaru e rawaka ana.
- Te āheinga waikura: Ka ranea te āputa waikura mō ngā mea kawa me te waikura pāmahana teitei, ka roa ake te ora o te hoahoa.
- Te auau ngokingokiHe pai ake te ātete o te hanganga pakitara taumaha ki te ngoki pāmahana teitei mō te wā roa, ka whakaiti i te tūponotanga o te whakarerekētanga me te pakaru.
