Cov kav dej AWWA C200 steel yeeb nkab yog dav siv hauv cov teb / kev lag luam hauv qab no:

Hydraulic fais fab chaw nres tsheb, potable

Kev lag luam khoom noj khoom haus, dej twj tso kua mis, dej phwj pov tseg cov yeeb nkab kab

AWWA C200 cov qauv npog pob tw-welded, ncaj-seam los yog kauv-seam welded structural steel yeeb nkab, 6 in. (150 mm) thiab loj dua, rau kev sib kis thiab xa dej, suav nrog kev tsim cov yeeb nkab, kev xav tau ntawm kev ua haujlwm vuam, kev tso cai hloov pauv ntawm qhov hnyav thiab qhov ntev, kev npaj ntawm qhov xaus, kev tsim tshwj xeeb, kev tshuaj xyuas, thiab cov txheej txheem kuaj.

Kev tshuaj xyuas

Txhua txoj haujlwm ua tiav thiab cov khoom uas tau muab tso rau hauv tus qauv no tuaj yeem raug tshuaj xyuas los ntawm tus neeg yuav khoom, tab sis qhov kev tshuaj xyuas no yuav tsis txo cov neeg tsim khoom ntawm lub luag haujlwm los muab cov khoom siv thiab ua haujlwm raws li tus qauv no.

Kev ruaj ntseg zoo

Cov chaw tsim khoom yuav tsum tswj hwm qhov kev lees paub zoo los xyuas kom meej tias cov qauv tsawg kawg nkaus tau ua tiav.Nws yuav tsum suav nrog tus kws tshuaj ntsuam xyuas vuam (AWS QC1) los xyuas kom meej tias cov vuam vuam thiab cov txheej txheem vuam yog tsim nyog, cov txheej txheem raug ua raws li kev txwv ntawm kev sim, thiab kev ua haujlwm zoo-kev lees paub.

Tsis zoo

Cov yeeb nkab ua tiav yuav tsum tsis muaj qhov tsis txaus ntseeg.Qhov tsis xws luag hauv cov yeeb nkab seamless lossis hauv niam txiv hlau ntawm welded steel yeeb nkab yuav raug suav tias yog qhov tsis txaus ntseeg thaum qhov tob ntawm qhov tsis xws luag yog ntau dua 12.5% ​​ntawm nominal phab ntsa thickness.

Kev kho qhov tsis xws luag yuav tsis raug tso cai yog tias qhov tob ntawm qhov tsis zoo tshaj 1/3 ntawm nominal phab ntsa thickness ntawm cov yeeb nkab thiab yog tias qhov ntev ntawm qhov tsis xws luag hauv qhov tob tshaj 12.5% ​​yog ntau dua 25% sab nraud txoj kab uas hla ntawm cov yeeb nkab.Txhua qhov ntev ntawm cov yeeb nkab kho yuav tsum tau sim hydrostatically raws li tus qauv yuav tsum tau ua.

Kev lag luam

Ib tus lej xov tooj lossis lwm yam kev qhia yuav tsum tau pleev xim rau hauv qhov chaw pom tseeb ntawm txhua ntu ntawm cov yeeb nkab me me thiab txhua ntu tshwj xeeb.
