Kodi Valve ya Chipata cha API 600 ndi chiyani?
TheMuyezo wa API 600(American Petroleum Institute) ikulamulirama valve achitsulo otchingira bonnetyokhala ndi malekezero opindika kapena opindika. Izi zikuphatikizapo zofunikira pakupanga, kupanga, ndi kuyesaMa Valves a Chipata cha API 600amagwiritsidwa ntchito m'mafakitale amafuta, gasi, ndi petrochemical.
Zofunikira Zazikulu za API 600 Standard:
- Kapangidwe:Imalamula nyumba za chipata chimodzi (zolimba/zotanuka)
- Zipangizo:Zitsulo zapadera zogwiritsidwa ntchito potentha kwambiri
- Kuyesa:Mayeso okhwima a chipolopolo ndi mayeso otayira madzi pampando
- Chiwerengero:Zokhazokha za ma valve achitsulo okhala ndi mabowo omangiriridwa
Kodi ma valve a API 6D ndi chiyani?
TheMuyezo wa API 6D (Ma Vavulo a Paipi) imayang'anira mitundu yosiyanasiyana ya ma valve a machitidwe a mapaipi, kuphatikizapoMa Valves a Chipata cha API 6D, Ma Vavu a Mpira a API 6D, Ma Vavulovu Oyang'anira API 6DndiMa Valves a Pulagi a API 6D.
Zofunikira Zazikulu za Muyezo wa API 6D:
- Mitundu ya Valavu:Ma valve a mapaipi odzaza ndi chitoliro (chipata, mpira, cheke, pulagi)
- Zipangizo:Ma alloy osagwira dzimbiri omwe amagwiritsidwa ntchito ngati wowawasa (monga malo a H₂S)
- Kuyesa:Mayeso a mipando okhala ndi nthawi yayitali + mayeso a mpweya woipa womwe umatuluka
- Cholinga cha Kapangidwe:Kutha kupirira, kubisa ntchito, ndi kuthekera kotseka mwadzidzidzi
Kusiyana Kwakukulu: Ma Valves a API 600 vs API 6D
| Mbali | Valavu ya API 600 | Valavu ya API 6D |
|---|---|---|
| Mitundu ya Ma Vavu Ophimbidwa | Ma Vavulovu a Chipata cha Chitsulo okha | Ma Valves a Chipata, Mpira, Chongani, ndi Pulagi |
| Kapangidwe ka Valavu ya Chipata | Chipata chimodzi cha mtundu wa wedge (cholimba/chotanuka) | Chipata chofanana/chokulirapo (chopangidwa ndi slab kapena chodutsa m'njira) |
| Miyezo ya Valavu ya Mpira | Sizinaphimbidwe | Ma Vavu a Mpira a API 6D(mapangidwe a mipira yoyandama/yokhazikika) |
| Yang'anani Miyezo ya Ma Vavu | Sizinaphimbidwe | Ma Vavulovu Oyang'anira API 6D(kugwedezeka, kukweza, kapena mbale ziwiri) |
| Miyezo ya Ma Valuvu a Pulagi | Sizinaphimbidwe | Ma Valves a Pulagi a API 6D(yothira mafuta/yosathira mafuta) |
| Kugwiritsa Ntchito Koyamba | Mapaipi opangira makina oyeretsera | Mapaipi otumizira (kuphatikizapo makina otha kunyamula nkhumba) |
| Kuyang'ana Kwambiri | Kukanikizana kwa wedge ndi mpando | Zofunikira pa double-block-and-bleeding (DBB) |
Nthawi Yosankha Ma Valves a API 600 vs API 6D
Mapulogalamu a API 600 Gate Valve
- Machitidwe otseka njira zoyeretsera zinthu
- Utumiki wa nthunzi yotentha kwambiri
- Mapaipi ambiri a zomera (osasinthika)
- Mapulogalamu ofunikira kutseka chipata cha wedge
Mapulogalamu a Valve a API 6D
- Ma Valves a Chipata cha API 6D:Kupatula mapaipi ndi kuyika nkhumba
- Ma Vavu a Mpira a API 6D:Kuzimitsa mwachangu mu mizere yotumizira magiya
- Ma Vavulovu Oyang'anira API 6D:Chitetezo cha pampu m'mapaipi
- Ma Valves a Pulagi a API 6D:Kuwongolera kayendedwe ka madzi mbali zonse ziwiri
Kusiyana kwa Chitsimikizo
- API 600:Satifiketi Yopangira Ma Valavu a Chipata
- API 6D:Chitsimikizo chokwanira cha dongosolo labwino (chimafuna API Monogram)
Kutsiliza: Kusiyanitsa Kofunika
Ma Valves a Chipata cha API 600akatswiri pakupanga mapangidwe a zipata za fakitale yoyeretsera zinthu, pomweMa Vavu a API 6DKuphimba mitundu yosiyanasiyana ya ma valavu opangidwa kuti agwire bwino ntchito ya mapaipi. Kusiyana kwakukulu ndi:
- API 600 ndi ya ma valavu okha; API 6D imaphimba mitundu inayi ya ma valavu
- API 6D ili ndi zofunikira zolimba zopezera zinthu/kutsata
- Kugwiritsa ntchito mapaipi kumafuna API 6D; mafakitale opangira zinthu amagwiritsa ntchito API 600
Gawo la Mafunso Ofunsidwa Kawirikawiri
Q: Kodi API 6D ingalowe m'malo mwa API 600 ya ma valve a chipata?
A: Pokhapokha pakugwiritsa ntchito mapaipi. API 600 ikadali muyezo wa fakitale yoyeretsera ma valve a chipata cha wedge.
Q: Kodi ma valve a mpira a API 6D ndi oyenera kugwiritsa ntchito mpweya wowawasa?
A: Inde, API 6D imafotokoza zinthu za NACE MR0175 za ntchito ya H₂S.
Q: Kodi ma valve a API 600 amalola kuti magazi azituluka kawiri?
A: Ayi, ntchito ya DBB imafuna ma valve ogwirizana ndi API 6D.
