Kupu Whakataki: He aha te Hiranga o te API 598
Te pono o te takirere, tētahi wāhi e kore e taea te whakararu Ahakoa te hinu, te hau, te matū hinu rānei, ko ngā hiahia ahumahi te mea nui rawa atu mō ō takirere.Tirotiro Takirere API 598ā, ko te Whakamātautau te paerewa tūturu a te umanga mō te whakatū i te hanganga me te rohe pēhanga o te takirere, me te whakatau i te kaha o te takirere ki te whakatutuki i te tere turuturu e whakaaetia ana e te waehere. Mā tēnei whakatakotoranga ka whakatūria he paearu ōrite mā ngā Kaitirotiro ki te whakatau i te kounga, me tētahi pūnaha hei whakaoho i te tirotiro anō (me ētahi atu mahi whakatika rānei) ina whakapaetia ngā āhuatanga.
He aha te API 598
I whakaputaina e teTe Whare Hinu o Amerika (API), e whakamārama ana te API 598 i ngā tikanga tirotiro me te whakamātautau pēhanga i mua i te tuku mō ngā takirere whakarewa e whakamahia ana i roto i ngā ahumahi warowaihā.
Ngā Whāinga Matua
• Manatokohia te kaha o te hanganga (te pupuri i te pēhanga)
• Whakamana i te mahi hiri (te turuturu o roto/o waho)
• Whakapūmautia ngā paearu whakaae puta noa i te ao
Te Hiranga Matua
• Mō ngā Kaitirotiro: Ka whakarato i ngā tikanga whakamātautau ka taea te whakatinana
• Mō ngā Kaihoko: Koinei te pūtake o ngā whakaritenga hoko me te tutuki i ngā ture
Ngā Tukanga Whakamātautau API 598: Te Whakatutukitanga i ngā Tikanga Taumata-i-te-Taumata
1. Whānuitanga me ngā Paerewa Tohutoro
Ngā Whakatakotoranga mō ngā Takirere Kēti Rino, ngā Pito Whakarewa, ngā Pito Whakarewa rānei, ngā Pōtae Whakapūmau. 34, me ētahi atu).
2. Ngā Whakaritenga Tirotiro
• Kawenga: E arahina ana e te kaihanga
• Ngā Tirotiro Matua:
→ Tiwhikete rauemi
→ Te tika o te āhua
→ NDT (RT/UT/MT/PT ki A519M)
→ Ngā hapa tirohanga
→ Te tutuki i ngā tohu/ingoa
→ Te pono o te paninga
3. Whakamātautau Pēhanga (Wāhanga Hiranga)
Ngā Momo me ngā Tukanga Whakamātautau
| Momo Whakamātautau | Kaupapa | Āhua o te Takirere | Waenga | Pēhanga | Roanga (min) |
|---|---|---|---|---|---|
| Whakamātautau Anga | Tinana/Pona | Tuwhera | Wai | 1.5x MAWP @ 38°C (100°F) | ≥NPS 2: 60s |
| Whakamātautau Nohoanga o Muri | Te Hiri o te Pōtae o te Kākano o Muri (Mēnā ka Whakamahia) | Tuwhera | Wai/Hau (Iti) | 1.1x MAWP @ 38°C (100°F) | = Whakamātautau Anga |
| Whakamātautau Nohoanga Pēhanga Teitei | Te Katinga Hiri Tuatahi | Kua kati | Wai (Ngā takirere wai) | 1.1x MAWP @ 38°C (100°F) | NPS 4+: 60s |
| Whakamātautau Nohoanga Pēhanga Iti | Manatoko hiri hau | Kua kati | Hau/Hauota | 0.5–0.7 MPa (6–8 pae) | = Pēhanga-Teitei |
| Whakamātautau DBB | Mahi Wehewehe me te Toto Rua | Kua kati | Wai/Hau | Whakamātautau mō ia Nohoanga | Whakamātautau mō ia Nohoanga |
Te Roanga o te Pēhanga Whakamātautau e Hiahiatia ana – Mai i te API 598 Ripanga 4
Paearu Whakaae ki te turuturu
• Ngā Whakamātautau Anga/Nohoanga Muri: Kāore he turuturu e kitea ana
• Whakamātautau Wai Pēhanga-Teitei (Nohoanga Whakarewa): Kāore he pata e kitea ana
• Ngā Reiti Mirumiru Whakamātautau Hau (i roto i ngā mirumiru ia meneti):
| Momo Takirere | Rahi (NPS) | Ngā Mirumiru Mōrahi/min |
|---|---|---|
| Keti/Poro/Pōro | ≤2.5 | 0 |
| 3–6 | 12 | |
| ≥8 | 20 | |
| Pūrerehua (Metara) | ≤2.5 | 0 |
| 3–6 | 24 | |
| ≥8 | 40 | |
| Ngā Nohoanga Ngāwari Katoa | tetahi | 0 |
Tauira Pūrongo mō te Whakamātautau Pēhanga Takirere
4. Te Whakahaere i Muri i te Whakamātautau
Te whakamaroke ā-ture (he mea nui ki te maitai kore waikura) me te tiaki anō.
5. Tiwhikete
Kei roto i ngā takirere hanganga ture te tohu API (mēnā e hiahiatia ana) me ngā pūrongo whakamātautau.
Ngā Takirere i Taupokina e te API 598
Mō ngā takirere whakarewa me te kaihanga ki:
√API 6D: Ngā Takirere Paipa Raina (Pōro/Kūaha/Pūrua/Tirohia)
√API 6A: Ngā Takirere Puna
√API 600/602/603: Ngā Takirere Kēti Rino
√API 608: Ngā Takirere Pōro Whakarewa
√API 609: Ngā Takirere Pūrerehua
√API 623: Ngā Takirere Porowhita Rino
Te Kaupapa Matua:He paerewa whakamātautau te API 598. Ko ngā hoahoa/rauemi takirere kua tohua e ngā paerewa hua (API 6D me ērā atu). Me tohu ngā kirimana i NGĀ MEA E RUA.
He Aratohu Whaihua mō ngā Tohunga
Mō ngā Kaitirotiro
1. Putanga API 598 hou kua oti te whakahaere me ngā paerewa hua.
2. Ia hauwhā, I mua i te whakahaere i te whakamātautau, whakatikatikahia ngā taputapu whakamātautau (ngā ine, me ētahi atu).
3. Tuhia te maha o ngā mirumiru/whakaahuahia ngā turuturu
4. Whakaūtia te haumaru i te wā e whakamātautau ana i te hau
Mō ngā Rōpū Hoko
1. Whakaurua ki roto i ngā kirimana: Whakawhirinaki ki tētahi Whakamātautau Whakaae o te Wheketere (FAT) kua kitea
• "Me whakamātautau ngā takirere kia rite ki te API 598, Putanga 11 (hou rawa atu)"
• Ngā whakatakotoranga hua e tika ana (hei tauira, API 6D Putanga 25)
2. Tonoa ngā pūrongo whakamātautau taketake kua hainatia
3. Whakaurua ngā whakaritenga tāpiri:
• Whakamātautau ahi (API 607/6FA)
• Ngā tukunga rerenga (ISO 15848)
Whakamutunga: Te Hiranga o te Kounga
Ehara te API 598 i te paerewa noa iho—koinei te arai tuatahi mō ngā hapa e pā ana ki ngā takirere. Ki ngā kaitirotiro, koinei te pukapuka rautaki matua. Mō te hoko, koinei te whakaiti i te mōrearea. I ngā āhuatanga ratonga e piki haere ana te kino, ehara te piripono ki te API 598 i te kōwhiringa—e hiahiatia ana e ngā pakihi kia haumaru, kia tika ai te taiao, kia pono ai hoki.
