TusMiskas Dej Ua Haujlwm Koom Tes (AWWA)yog cov thawj coj coj uas tsim cov qauv thiab cov lus qhia rau cov tshuab dej. Kev to taubAwwas qauv, Flange hom, cov ntaub ntawv, thiab kev sib piv thoob ntiaj tebyog qhov tseem ceeb rau cov engineers, cov neeg tsim qauv, thiab cov kws tshaj lij ua haujlwm ua haujlwm hauv kev kho dej thiab xa dej pipeline.
1. Dab tsi yog AWWA?
Awwa (American Dej ua haujlwm koom nrog)yog ib lub koom haum tau mob siab kom txhim kho cov dej ua kom zoo, kev nyab xeeb, thiab kev ntseeg tau hauv cov tshuab khoom noj.
Cov Tseem Ceeb:
Tsim kom muabCov Qauv thiab Cov Lus QhiaRau cov kav dej, li qub, flanges, thiab fittings hauv dej
Kom ntseeg tausib xyaw, kev nyab xeeb, thiab kev ua haujlwmNtawm Dej Khoom Siv Hluav Taws Xob
Cuam tshuam ob qho tib siKev khiav teb thiab muaj dej tshuab thoob ntiaj teb
2. Awwa flanges thiab fittings: hom, cov ntaub ntawv, thiab cov ntawv thov
Awwa flanges thiab fittings yog tsim los muabTxhim khu kev qha, txia - Cov ntaub ntawv sib txuashauv kev faib dej thiab kho tshuab.
Hom:
Chav Kawm D Flange:Txheem Flange Rau Cov Khoom Siv Dej Raug Dej Kav Pipelines
Chav Kawm C Flange:Siv rau nruab nrab lub tshuab siab
Chav Kawm E Flange:Tsim rau cov ntawv thov siab dua
Khoom:
Carbon Steel:Muaj zog thiab yig rau cov raj xa dej loj
Tus Hlau Stainless:Corrosion {{0 {}} tiv taus dej txhoj puab heev
Coo cov hlau (DI):Ntau yam hauv nroog hauv nroog tau vim muaj kev ruaj khov
Cov Ntawv Thov:
Dej Kho Nroj Tsuag
Lub nroog dej twj tso kua mis
Irrigation Tshuab
Muaj dej faib
3. AWWA Cov Qauv VS ASME thiab ISO Cov Qauv
Piv rauAwwa flanges thiab cov qauv nrog asme thiab isoPab ua kom tsim kev tsim tsim nyog, ua tiav, thiab kev teeb tsa:
| Yam zoo | Awwa flange | ASME Flange | ISO Flange |
|---|---|---|---|
| Yeeb Nkab Loj | DN 50 - DN 2000 | NPS 1/2 - 24 " | DN 10 - DN 2000 |
| Siab Ntsuam | 150 #, 300 # (raug) | 150# – 2500# | PN6 - PN40 |
| Cov Khoom Siv Khoom Siv | Carbon Hlau, Stainless hlau, ductile hlau | Carbon Steel, Alloy Steel, Stainless Hlau | Carbon Hlau, Stainless Hlau, Alloy Steel |
| Bolt qauv | Ib AWWA chav kawm C, D, E | Ansi / Asme Txuj Ci Bolt Qauv | Metric Bolt Qauv |
| Cov Ntawv Thov | Dej Pipelines, Cov Nroj Tsuag | Muaj cov piping, roj & roj | Kev Lag Luam Industrial Pipelines |
Cov Lus Qhia Ua Tau:
Nrhiav pov thawjBolt qauv, Flange qhov ntev, thiab kev ntsuas siab
Ua kom tau tiag tiagKev sib xyaw nrog cov ntaub ntawv xa hluav taws xob uas twb muaj lawm
XaivAwwa rau cov dej num dej, Thaum ASME / ISO yuav suav nrog kev lag luam lossis thoob ntiaj teb
4. Xaus
Kev to taubAwwas qauv, Flange hom, cov ntaub ntawv, thiab yuav ua li cas lawvPiv nrog ASME thiab ISO Cov Qauvyog qhov tseem ceeb rau kev kho dej thiab xa dej pipeline. Kev Xaiv Kom Tsim nyogSystem Muaj kev ntseeg tau, tso dej xau - kev ua haujlwm pub dawb, thiab ua raws li cov qauv haujlwm thoob ntiaj teb, muab cov lus ntev - sij hawm kev nyab xeeb thiab kev ua haujlwm hauv cov av hauv av.
