Qhia:

Nyob rau hauv daim teb ntawm cov txheej txheem tsim qauv, qhov tseem ceeb ntawm kev siv cov ntaub ntawv zoo thiab txoj kev tsim qauv tsis tuaj yeem dhau los. Ntawm cov ntau yam siv hauv kev tsim kho cov dej num, cov kav dej ua si ib lub luag haujlwm tseem ceeb. Peb yuav tso lub teeb rau qhov tseem ceeb ntawm ob chav welded welded thiab tshawb lawv cov yam ntxwv, yuav ua li cas lawv tuaj yeem pab txhawb kev ua kev ncaj ncees.

Kawm txog ob chav welded pipes:

Ob chav Welded yeeb nkab, tseem hu ua ob chav submerged arc welded yeeb nkab (Dsaw kav), yog tsim los ntawm kev siv submerged arc vuam txheej txheem. Cov thev naus laus zis suav nrog kev sib cais ntev ntev ntawm ob daim paib cais, muab kev sib txuas muaj zog thiab txuas ntxiv. Cov kab dej no feem ntau siv hauv cov ntawv thov kev siab siab, cov dej hauv av thiab roj kev tshawb nrhiav, thiab cov platform sab nrauv.

Txhim khu cov qauv txheej txheem ncaj ncees:

Qhov tseem ceeb rau kev sivOb Chav Welded Yeeb Nkabyog lawv lub peev xwm los txhim kho cov qauv kev ntseeg siab. Nrog kev sib cav thiab muaj zog welds, cov kav dej no muaj kev ntxhov siab zoo dua thiab kav ntev. Ob chav weld ob npaug kom cov yeeb nkab uas tuaj yeem tiv thaiv ntau qib siab, ua rau nws zoo tagnrho rau weld tej zaum yuav muaj kev nyab xeeb rau kev nyab xeeb. Qhov txheej txheem vuam no tshem tawm qhov txeej lossis cov kab nrib pleb, kom ntseeg tau ntev kev ntseeg tau ntawm koj cov piping system.

Lub zog siab dua rau qhov hnyav piv:

Ob chav Welded yeeb nkab muaj lub zog zoo tshaj plaws rau qhov hnyav piv. Vim yog cov txheej txheem vuam, cov kav dej no tau txo cov phab ntsa tuab thiab yog sib dua thaum tswj cov qauv nruj. Qhov no muaj zog piv kom tau zoo dua tag nrho cov kev daws teeb meem rau cov qauv kev txhawb nqa xws li cov choj, yees, thiab cov tsev nce siab.

Corrosion Kuj:

Lwm qhov txiaj ntsig tseem ceeb ntawm ob welded yeeb nkab yog nws corrosion tsis kam. Ib lub taub hau tig tig tau tsim muaj zog tiv thaiv sab nraud yam, suav nrog kev ya raws, tshuaj lom neeg thiab cov av. Qhov no txwv tsis pub sab hauv ntawm cov yeeb nkab los ntawm cov neeg sawv cev corrosive, ua kom muaj kev pab ntau dua piv rau cov kav dej. Cov khoom siv corrosion-resistant ntawm cov kav dej no yog cov muaj txiaj ntsig tshwj xeeb rau cov roj thiab roj kev lag luam, qhov twg pip feem ntau ntsib cov xwm txheej hnyav.
