Kupu Whakataki: He aha te hiranga o ngā paerewa API mō ngā takirere ahumahi?
I roto i ngā ahumahi mōrearea nui pēnei i te hinu me te hau, ngā matū me te hiko, ka pā tika te haumaru me te pono o ngā takirere ki te pumau o ngā pūnaha whakaputa. Ko ngā paerewa i whakatakotoria e te API (American Petroleum Institute) te pukapuka hangarau o ngā takirere ahumahi huri noa i te ao. I roto i ēnei, ko te API 607 me te API 608 ngā whakatakotoranga matua e whakahuatia pinepinetia ana e ngā miihini me ngā kaihoko.
Ka tātarihia hōhonutia e tēnei tuhinga ngā rerekētanga, ngā āhuatanga tono me ngā āhuatanga tutuki i ngā whakaritenga o ēnei paerewa e rua.
Upoko 1: Te whakamārama hōhonu o te paerewa API 607
1.1 Te whakamāramatanga paerewa me te kaupapa matua
Ko te API 607 "Te whakatakotoranga whakamātautau ahi mō ngā takirere hurihanga 1/4 me ngā takirere nohoanga takirere kore-whakarewa" e arotahi ana ki te manatoko i te mahi hiri o ngā takirere i raro i ngā āhuatanga ahi. Ko te putanga 7 hou ka whakanui ake i te pāmahana whakamātautau mai i te 1400°F (760°C) ki te 1500°F (816°C) hei whakatauira i ngā āhuatanga ahi kino ake.

- Paerewa tere turuturu: Kāore te tere turuturu mōrahi e whakaaetia ana e neke ake i te ISO 5208 Rate A
- Waenga whakamātautau: Whakamātautau whakakotahitanga o te hau mura (methane/hau māori) me te wai
- Āhuatanga pēhanga: Whakamātautau hihiri o te 80% o te pēhanga kua whakatauria
Upoko 2: Tātari hangarau o te paerewa API 608
2.1 Te tūnga paerewa me te whānuitanga o te tono
Mā te API 608 "Ngā takirere pōro whakarewa me ngā pito flange, ngā pito miro me ngā pito whakarewa" ka whakataurite i ngā whakaritenga hangarau o te tukanga katoa mai i te hoahoa ki te hanga i ngā takirere pōro, e kapi ana i te awhe rahi o DN8~DN600 (NPS 1/4~24), me te taumata pēhanga ASME CL150 tae atu ki te 2500LB.
2.2 Ngā whakaritenga hoahoa matua
- Hanganga tinana takirere: ngā whakatakotoranga tukanga whakarewa kotahi-wahi/wehewehe
- Pūnaha hiri: ngā whakaritenga ā-ture mō te mahi poraka takirua me te mahi whakaheke toto (DBB)
- Te taipana whakahaere: kāore te kaha whakahaere mōrahi e neke ake i te 360N·m
2.3 Ngā tūemi whakamātautau matua
- Whakamātautau kaha anga: 1.5 ngā wā pēhanga kua whakatauria mō te 3 meneti
- Whakamātautau hiri: 1.1 ngā wā whakamātautau rua-ara pehanga whakatauranga
- Te roa o te huringa: neke atu i te 3,000 ngā whakamanatanga mahi whakatuwheratanga me te kati katoa
Upoko 3: Ngā rerekētanga matua e rima i waenga i te API 607 me te API 608
| Ngā inenga whakatairite | API 607 | API 608 |
| Tūnga paerewa | Tiwhikete mahi ahi | Ngā whakaritenga hoahoa me te hanga hua |
| Atamira e tika ana | Wāhanga tiwhikete hua | Te tukanga hoahoa me te whakaputa katoa |
| Tikanga whakamātautau | Whakatauira ahi whakangaro | Whakamātautau pēhanga/mahinga tuku iho |
Upoko 4: Whakatau kōwhiringa hangarau
4.1 Te whakakotahitanga ā-ture mō ngā taiao mōrearea nui
Mō ngā papaaho taiwhenua, ngā taunga LNG me ētahi atu wāhi, e taunakihia ana kia whiriwhiria:
API 608 pōro takirere + API 607 tiwhikete tiaki ahi + tiwhikete taumata haumaru SIL
4.2 Otinga arotau utu
Mō ngā tikanga mahi tuku iho, ka taea e koe te whiriwhiri:
API 608 paerewa takirere + tiaki ahi ā-rohe (pēnei i te paninga ātete ahi)
4.3 Whakatūpato mō ngā hē o te whiriwhiringa
- Te whakapono hē kei roto i te API 608 ngā whakaritenga tiaki ahi
- Te whakataurite i te whakamātautau API 607 me ngā whakamātautau hiri tikanga
- Te kore aro ki ngā arotakenga wheketere o ngā tiwhikete (ngā whakaritenga pūnaha API Q1)
Upoko 5: Ngā Pātai Auau (FAQ)
Q1: Ka tutuki aunoa te takirere API 608 i ngā whakaritenga API 607?
A: Kāore i te tino pono. Ahakoa ka taea te tono mō te tiwhikete API 607 mō ngā takirere pōro API 608, me whakamātautau motuhake.
Q2: Ka taea tonu te whakamahi i te takirere i muri i te whakamātautau ahi?
A: Kāore i te tūtohutia. I muri i te whakamātautau, he maha ngā wā ka pakaru te hanganga o ngā takirere, ā, me tango atu.
Q3: He aha te pānga o ngā paerewa e rua ki te utu o ngā takirere?
A: Ka piki ake te utu mā te tiwhikete API 607 mā te 30-50%, ā, ka pā te tutuki i ngā whakaritenga API 608 ki te 15-20%.
Whakatau:
• He mea nui te API 607 mō te whakamātautau ahi o ngā takirere pūrerehua nohoanga-ngohengohe me ngā takirere pōro.
• Mā te API 608 ka whakarite te hanganga me te mahi tika o ngā takirere pōro nohoanga-whakarewa me ngā takirere pōro nohoanga-ngawari e whakamahia ana i ngā mahi ahumahi.
• Mena ko te haumaru ahi te mea matua e whakaarohia ana, me whai i ngā takirere e tutuki ana i ngā paerewa API 607.
• Mō ngā tono takirere pōro whānui me te pēhanga teitei, ko te API 608 te paerewa e tika ana.
