Kev Ntsuas Hydrostatic

cov lus piav qhia txog khoom1

Cov yeeb nkab yuav tsum tiv taus qhov kev sim hydrostatic yam tsis muaj qhov xau los ntawm cov weld seam lossis lub cev yeeb nkab
Cov khoom sib koom ua ke tsis tas yuav tsum tau kuaj hydrostatically, tsuav yog cov feem ntawm cov yeeb nkab siv los cim cov khoom sib koom ua ke tau raug kuaj hydrostatically ua ntej kev ua haujlwm sib koom ua ke.

1. Lub zog ntawm cov yeeb nkab hlau uas muaj kauv welded:

Cov yeeb nkab carbon steel kauv sib txuasmuaj zog dua vim nws txoj kev tsim khoom tshwj xeeb. Los ntawm kev siv cov khoom siv kub-kub dov, cov yeeb nkab raug tsim los ntawm kev sib txuas ua ke, ua rau muaj kev sib txuas tas mus li. Qhov no ua lub luag haujlwm tseem ceeb hauv kev tswj hwm qhov kev ua haujlwm ntawm cov yeeb nkab, xyuas kom meej tias nws tuaj yeem tiv taus kev nyuaj siab thiab cov xwm txheej ib puag ncig nyuaj. Nws lub zog tensile siab ua rau nws yog qhov kev xaiv txhim khu kev qha rau kev siv dej hauv tsev thiab kev lag luam.

2. Kev ruaj khov thiab kev tiv thaiv xeb:

Ib qho teeb meem loj nrog cov dej num tsim kho vaj tse yog xeb ntawm cov kav dej raws sijhawm. Cov kav dej carbon steel uas sib txuas ua ke ua rau muaj kev tiv thaiv xeb zoo heev vim nws cov txheej zinc lossis epoxy tiv thaiv. Cov txheej txheej ua haujlwm ua ib qho thaiv rau cov khoom sab nraud, tiv thaiv xeb thiab ua kom koj cov kav dej siv tau ntev. Lawv txoj kev tiv thaiv xeb ua kom muaj txiaj ntsig zoo mus sij hawm ntev thaum txo cov nqi kho cov kav dej.

3. Kev siv tau ntau yam:

Cov yeeb nkab hlau carbon uas sib txuas ua ke yog siv tau ntau yam thiab haum rau yuav luag txhua qhov project tsim kho dej. Txij li cov network faib dej haus mus rau cov chaw kho dej khib nyiab, cov yeeb nkab no tuaj yeem hloov kho raws li qhov xav tau tshwj xeeb ntawm txhua qhov project. Tsis tas li ntawd, lawv qhov kev ywj pheej ua rau lawv yooj yim rau kev teeb tsa, txawm tias nyob rau hauv thaj chaw nyuaj lossis thaj chaw muaj av qeeg.

4. Kev siv nyiaj tsim nyog:

Cov haujlwm tsim kho dej feem ntau ntsib kev txwv nyiaj txiag, ua rau kev siv nyiaj tsim nyog yog qhov tseem ceeb. Cov yeeb nkab carbon steel welded yog cov yeeb nkab pheej yig vim nws lub neej ntev thiab ruaj khov. Lawv lub neej ua haujlwm ntev dua, ua ke nrog kev xav tau kev saib xyuas tsawg, txo cov nqi siv ntawm qhov project. Tsis tas li ntawd, cov thev naus laus zis vuam yeeb nkab carbon tau ua tiav hauv xyoo tas los no, ua kom zoo dua qhov kev vuam zoo thiab txo cov nqi ntxiv.

5. Kev xav txog ib puag ncig:

Kev ruaj khov yog qhov tseem ceeb uas yuav tsum xav txog hauv kev tsim kho vaj tse niaj hnub no. Cov kav dej hlau uas sib txuas ua ke ua raws li cov ntsiab cai no vim tias lawv rov ua dua tau 100%, pab txo cov pa roj carbon hauv lub sijhawm ntev. Lawv qhov kev siv rov ua dua tshiab txhawb nqa kev lag luam ncig thaum muab kev daws teeb meem txhim khu kev qha thiab zoo rau ib puag ncig rau kev thauj mus los hauv dej.

Xaus lus:

Cov yeeb nkab carbon steel uas tau muab kauv sib txuas tau hloov pauv txoj kev lag luam dej, tsa cov kab rau kev vuam yeeb nkab carbon thiabcov kab dejCov kav dej no muaj zog heev, ruaj khov, tiv taus xeb thiab siv tau ntau yam, muab kev daws teeb meem txhim khu kev qha thiab pheej yig rau cov zej zog cov kev xav tau dej uas loj hlob tuaj. Los ntawm kev xaiv cov kav dej carbon steel uas sib txuas ua ke, peb tuaj yeem tsim txoj hauv kev rau yav tom ntej dej uas ruaj khov thiab ruaj khov.
