Cov khoom sib txawv
Forged hlau:
Forged steel yog tsim los ntawm cua sov steel billets thiab shaping lawv nyob rau hauv siab. Cov txheej txheem no txhim kho cov qauv nplej, ua rau muaj zog zoo tshaj plaws ntawm cov tshuab, toughness, thiab tsis kam mus rau high-pressure / kub ib puag ncig. Cov qib uas muaj xws liASTM A105 carbon hlauthiabASTM A182 Stainless hlau.
Hlau Casting:
Cam khwb cia hlau yog tsim los ntawm pouring molten steel rau hauv pwm. Thaum tus nqi-zoo rau cov duab tsis yooj yim, nws tuaj yeem pom qhov porosity lossis tsis sib xws, txwv tsis pub siv rau hauv cov xwm txheej hnyav. Cov qib muaj xws li ASTM A216 WCB (carbon steel) thiab ASTM A351 CF8M (stainless hlau).
Qhov sib txawv tseem ceeb ntawm Forged Steel Valve thiab Cast Steel Valves
| Parameter | Forged steel li qub | Cam khwb cia hlau Valves |
| Qhov Loj | Me me (DN15-DN200, ½"-8") | Loj (DN50-DN1200, 2 "-48") |
| Kev ntsuas siab | Siab dua (Class 800–4500) | Nruab nrab (Class 150–600) |
| Kub | -29 ° C rau 550 ° C | -29 ° C rau 425 ° C |
| Daim ntawv thov | High-pressure pipelines, refineries | Tsawg / nruab nrab-siab tshuab, dej |
Valve Classifications
Forged steel li qub
1. Forged Steel Gate Valves (Class 800): Compact tsim rau high-pressure cais nyob rau hauv cov roj/gas systems.
2. Forged Steel Globe Valves: Precise flow control in steam or chemical services.
3. Forged Steel Check Valves: Tiv thaiv rov qab hauv compressors lossis twj tso kua mis (s viav vias / nqa hom).
4. Forged Steel Pob Valves: Kev kaw ceev ceev hauv Class 800 hydrocarbon pipelines.
Cam khwb cia hlau Valves
1. Cast Steel Gate Valves (Class 150-300): Kev cais cov kua dej ntau hauv kev kho dej.
2. Cam khwb cia Steel Globe Valves: General flow regulation nyob rau hauv HVAC systems.
3. Cast Steel Check Valves: Cov kev daws teeb meem qis rau cov kev pabcuam tsis tseem ceeb.
Vim Li Cas XaivChav Kawm 800 Forged Steel Valves
Chav Kawm 800 forged steel li qub tiv taus siab txog 1380 bar (20,000 psi) ntawm 38 ° C, ua rau lawv zoo tagnrho rau:
- Offshore roj rigs
- Kub-kub kab kab
- Hydrogen ua cov nroj tsuag
Xaus
Forged steel li qubua tau zoo nyob rau hauv ib puag ncig kev ntxhov siab vim lawv cov kev tsim kho muaj zog, thaum cam khwb cia steel li qub muab kev daws teeb meem rau cov tshuab loj, tsis tshua muaj siab. Kev xaiv hom yog nyob ntawm qhov yuav tsum tau ua, pob nyiaj siv, thiab cov qauv kev lag luam xws li ASME B16.34.
