Kusiyana kwa Zinthu
Chitsulo Chopangidwa:
Chitsulo chopangidwa chimapangidwa potenthetsa ma billet achitsulo ndikuwapanga pansi pa kupanikizika kwakukulu. Njirayi imawonjezera kapangidwe ka tirigu, zomwe zimapangitsa kuti makina akhale olimba kwambiri, olimba, komanso osagwirizana ndi malo omwe amapanikizika kwambiri/kutentha kwambiri. Magiredi ofanana ndi awa:ASTM A105 (chitsulo cha kaboni)ndiASTM A182 (chitsulo chosapanga dzimbiri).
Chitsulo Chopangidwa:
Chitsulo chopangidwa ndi chitsulo chimapangidwa pothira chitsulo chosungunuka mu nkhungu. Ngakhale kuti ndi chotsika mtengo pa mawonekedwe ovuta, chingasonyeze kufooka kapena kusasinthasintha, zomwe zimachepetsa kugwiritsidwa ntchito kwake m'mikhalidwe yovuta kwambiri. Magulu wamba ndi monga ASTM A216 WCB (chitsulo cha carbon) ndi ASTM A351 CF8M (chitsulo chosapanga dzimbiri).
Kusiyana Kwakukulu Pakati pa Valavu Yachitsulo Chopangidwa ndi Mavavu Achitsulo Chopangidwa ndi Mavavu
| Chizindikiro | Ma Vavulovu Achitsulo Chopangidwa | Ma Vavu a Chitsulo Otayidwa |
| Kukula kwa Kukula | Kakang'ono (DN15–DN200, ½”–8″) | Yaikulu (DN50–DN1200, 2″–48″) |
| Kuyeza kwa Kupanikizika | Zapamwamba (Kalasi 800–4500) | Pakati (Kalasi 150–600) |
| Kutentha | -29°C mpaka 550°C | -29°C mpaka 425°C |

Magulu a Ma Valves
Ma Vavulovu Achitsulo Chopangidwa
1. Ma Valves a Chipata cha Chitsulo Chopangidwa (Kalasi 800): Kapangidwe kakang'ono kosungira mafuta/gasi m'makina oyeretsera mafuta.
2. Ma Valves a Globe a Chitsulo Chopangidwa ndi Forged: Kuwongolera bwino kayendedwe ka madzi mu ntchito za nthunzi kapena mankhwala.
3. Ma Vavulopu Oyang'anira Chitsulo Chopangidwa: Pewani kubwerera kwa madzi m'ma compressor kapena mapampu (mitundu ya swing/lift).
4. Ma Vavu a Mpira Opangidwa ndi Zitsulo: Kuzimitsa mwachangu mapaipi a hydrocarbon a Class 800.
Ma Vavu a Chitsulo Otayidwa
1. Ma Vavulopu a Chipata cha Chitsulo Chopangidwa ndi Zitsulo (Kalasi 150–300): Kupatula madzi ambiri mu njira yoyeretsera madzi.
2. Ma Vavu a Globe Opangidwa ndi Zitsulo: Kulamulira kayendedwe ka madzi m'machitidwe a HVAC.
3. Ma Vavu Oyang'anira Zitsulo Zotayidwa: Mayankho otsika mtengo a ntchito zosafunikira.
Chifukwa ChosankhaMa Valves a Chitsulo Opangidwa ndi Kalasi 800
Ma valve achitsulo opangidwa ndi kalasi 800 amatha kupirira kupsinjika mpaka 1380 bar (20,000 psi) pa 38°C, zomwe zimapangitsa kuti akhale abwino kwambiri pa:
- Malo opangira mafuta akunja
- Mizere ya nthunzi yotentha kwambiri
- Malo opangira haidrojeni
Mapeto
Ma valve achitsulo opangidwaAmachita bwino kwambiri m'malo ovuta kwambiri chifukwa cha kapangidwe kake kolimba, pomwe ma vavu achitsulo chopangidwa ndi chitsulo amapereka njira zotsika mtengo zamachitidwe akuluakulu komanso otsika mphamvu. Kusankha mtundu woyenera kumadalira zofunikira pa ntchito, bajeti, ndi miyezo yamakampani monga ASME B16.34.
