Nhanganyaya: Nei API 598 Ichifanira Kukosha
Kuvimbika kwemavharuvhu panzvimbo imwe chete yausingakwanise kuikanganisa. Ingave iri yemafuta, gasi kana petrochemicals, zvinodiwa neindasitiri ndizvo zvinonyanya kudiwa nemavharuvhu ako.Kuongorora Vharuvhu yeAPI 598uye Kuedza ndiyo nzira inoshandiswa neindasitiri pakusimbisa miganhu yevharuvhu uye yekumanikidza uye yekuona kugona kwevharuvhu kutevedzera mwero wekubuda kwemvura unobvumidzwa wekodhi. Iyi nzira inosimbisa zvinodiwa zvinoenderana neVaongorori kuti vaone mhando, uye sisitimu yekukonzeresa kuongororwazve (kana imwe nzira yekugadzirisa) kana hunhu hwacho hwava kufungidzirwa.
Chii chinonzi API 598
Yakaburitswa neSangano reAmerican Petroleum (API), API 598 inotsanangura zvinosungirwa kuti zviitwe nekutarisa mafambiro emagetsi asati atumirwa uye maitiro ekuongorora kumanikidzwa kwemavharuvhu esimbi anoshandiswa mumaindasitiri emahydrocarbon.
Zvinangwa Zvikuru
• Tarisa kusimba kwechimiro (kubata kumanikidzwa)
• Kusimbiswa kwekushanda kwekuvhara (kubuda kwemukati/kunze kwemvura)
• Gadzirisa zvinodiwa kuti munhu abvumirwe pasi rose
Kukosha Kwakakosha
• Kune Vaongorori: Inopa nzira dzekuyedza dzinogona kushandiswa
• Kune Vatengi: Ndiyo hwaro hwezvinodiwa pakutenga uye kutevedzera mitemo
Maitiro Ekuyedza API 598: Kutevedzera Zvinodiwa Nhanho Nenhanho
1. Chiverengero & Maitiro Anotsanangurwa
Tsanangudzo yeSimbi Gate Valve, Flanged kana Butt Welding Ends, Bolted Bonnets. 34, nezvimwewo).
2. Zvinodiwa pakuongorora
• Mutoro: Inotungamirwa nemugadziri
• Maonero Akakosha:
→ Chitupa chezvinhu
→ Kururama kwehukuru
→ NDT (RT/UT/MT/PT kusvika A519M)
→ Zvirwere zvemaziso
→ Kutevedzera chiratidzo/kutevedzera plate yezita
→ Kuvimbika kwekuvhara
3. Kuedzwa kweDzvinyiriro (Chikamu Chakakosha)
Mhando dzeMiedzo & Maitiro
| Rudzi rweKuedza | Chinangwa | Nyika yeValve | Pakati nepakati | Kumanikidzwa | Nguva (miniti) |
|---|---|---|---|---|---|
| Kuedzwa kweShell | Muviri/Bhoneti | Vhura | Mvura | 1.5x MAWP pa 38°C (100°F) | ≥NPS 2: masekondi makumi matanhatu |
| Muedzo weChigaro Chekumashure | Chisimbiso cheBheniti yeStem yeKumashure (Kana Chikashandiswa) | Vhura | Mvura/Gasi (Yakaderera) | 1.1x MAWP pa 38°C (100°F) | = Kuedzwa kweShell |
| Kuedzwa kweChigaro Chine Kumanikidzwa Kwakanyanya | Kuvhara Kwechisimbiso Chekutanga | Yakavharwa | Mvura (mavharuvhu emvura) | 1.1x MAWP pa 38°C (100°F) | NPS 4+: masekondi makumi matanhatu |
| Kuedzwa kweChigaro Chine Kumanikidzwa Kwakaderera | Kuongororwa kwekuvharwa kwegesi | Yakavharwa | Mhepo/Nitrogen | 0.5–0.7 MPa (6–8 bar) | = Kumanikidzwa Kwakanyanya |
| Bvunzo reDBB | Kuzviparadzanisa Kwevanhu Vaviri & Basa reKubuda ropa | Yakavharwa | Mvura/Gasi | Bvunzo reChigaro Chega Chega | Bvunzo reChigaro Chega Chega |
Nguva Inodiwa Yekuyedza Kumanikidzwa - Kubva kuAPI 598 Tafura 4
Maitiro Ekugamuchira Kudonha Kwemvura
• Kuedzwa kweShell/Backseat: Hapana kubuda kwemvura kunooneka
• Kuedzwa kwemvura ine kumanikidzwa kwakanyanya (Chigaro chesimbi): Hapana madonhwe anooneka
• Mwero weMabubbles eKuedzwa kweGasi (mumabubbles paminiti):
| Rudzi rweVharuvhu | Saizi (NPS) | Mabhurumu Makuru/miniti |
|---|---|---|
| Gedhi/Globe/Bhora | ≤2.5 | 0 |
| 3–6 | 12 | |
| ≥8 | 20 | |
| Shashave (Simbi) | ≤2.5 | 0 |
| 3–6 | 24 | |
| ≥8 | 40 | |
| Zvigaro Zvese Zvakapfava | Chero chipi zvacho | 0 |
Muenzaniso weMushumo weKuedzwa kweVharuvhu
4. Kubata Mushure meKuedzwa
Kuomesa zvinhu nekumanikidzwa (zvakakosha kusimbi isingatsvi) uye kuchengetedza zvinhu zvakare.
5. Chitupa
Mavharuvhu ekutevedzera mitemo anouya neAPI monogram (kana zvichidikanwa) uye mishumo yekuyedza.
Mavharuvhu Akafukidzwa neAPI 598
Kune mavharuvhu esimbi ane chigadzirwa:
√API 6D: Mavharuvhu epombi yemutsetse (Bhora/Gedhi/Puragi/Chengeta)
√API 6A: Mavharuvhu Emusoro Wetsime
√API 600/602/603: Mavharuvhu eSimbi
√API 608: Mavharuvhu Esimbi Ebhora
√API 609: Mavharuvhu eBhatafurayi
√API 623: Mavharuvhu eSimbi
Pfungwa huru:API 598 ndiyo chiyero chekuyedza. Magadzirirwo/zvinhu zvevharuvhu zvinotsanangurwa zvichienderana nezvinodiwa zvechigadzirwa (API 6D nezvimwe zvakadaro). Zvibvumirano zvinofanirwa kuratidza ZVIRI ZVOSE.
Nhungamiro Inoshanda Kune Nyanzvi
Kune Vaongorori
1. Shanduro yeAPI 598 yazvino yakagadziriswa + mitemo yechigadzirwa.
2. Kota yega yega, Usati waedza, ongorora michina yekuyedza (mageji, nezvimwewo)
3. Kuverengwa kwemaburi emashoko/kuburitswa kwemifananidzo
4. Simbisai kuchengetedzeka panguva yekuyedzwa kwegasi
Kune Mapoka Ekutenga Zvinhu
1. Isawo muzvibvumirano: Vimba nebvunzo yekugamuchirwa kwefekitori (FAT) yakaonekwa
• “Mavharuvhu anofanira kuyedzwa zvichienderana neAPI 598, 11th Ed (yazvino)”
• Tsanangudzo yechigadzirwa inoshanda (semuenzaniso, API 6D 25th Ed.)
2. Kumbira mishumo yekutanga yakasainwa yebvunzo
3. Isa zvimwe zvinodiwa:
• Kuedzwa kwemoto (API 607/6FA)
• Utsi hunobuda mumhepo hunobuda mumhepo (ISO 15848)
Mhedziso: Hunhu Hunokosha
API 598 haisi nzira yekungoshandisa chete—ndiyo nzira yekutanga yekudzivirira kubva pakukundikana kwemavharuvhu. Kune vanoongorora, ndiyo nzira yekupedzisira yekudzivirira. Pakutenga, kuderedza njodzi kunoitika. Mumamiriro ezvinhu akaomarara ebasa, kutevedzera zvakanyanya API 598 hakusi sarudzo—mabhizinesi anoida kuti ive yakachengeteka, ine mutoro wezvakatipoteredza, uye yakavimbika.
