Cov ntsiab lus N-binding yuav tsum tau sau tseg rau hauv Daim Ntawv Tshuaj Xyuas.

Cov txheej txheem tsim khoom

Cov yeeb nkab uas vuam los ntawm txoj hlua khi, tseem hu ua SSAW (spiral submerged arc welded), yog tsim los ntawm kev siv cov txheej txheem spiral forming thiab submerged arc welding. Cov txheej txheem pib nrog kev kho ntug ntawm cov hlau coiled strip thiab tom qab ntawd khoov cov hlau ua ib lub voj voog. Tom qab ntawd siv automatic submerged arc welding los koom cov ntug ntawm cov hlau ua ke, tsim kom muaj kev sib txuas tas mus li raws li qhov ntev ntawm cov yeeb nkab. Txoj kev no ua kom ntseeg tau tias qhov sib koom ua ke muaj zog thiab ruaj khov thaum txo qhov tsis zoo thiab tswj tau qhov zoo ntawm cov qauv.

Qhov zoo ntawm cov yeeb nkab steel welded kauv

1. Lub zog thiab kev ruaj khov:Cov yeeb nkab carbon steel kauv sib txuasyog lub npe hu rau nws lub zog zoo tshaj plaws thiab kev ua haujlwm ntev, ua rau nws tsim nyog rau cov ntawv thov uas xav tau kev tiv thaiv siab thiab kev ua haujlwm ntev.

2. Kev Siv Nyiaj Tsim Nyog: Cov kav dej no muab kev daws teeb meem uas tsim nyog vim lawv cov txheej txheem tsim khoom zoo, cov nqi khoom siv raw qis dua, thiab cov neeg ua haujlwm tsawg dua piv rau lwm hom kav dej.

3. Kev Siv Tau Ntau Yam: Qhov kev siv tau ntau yam ntawm cov yeeb nkab carbon steel uas muaj kauv sib txuas ua rau nws siv tau ntau yam, suav nrog kev thauj mus los hauv dej, kev thauj mus los roj thiab roj av, cov qauv piling, cov dej phwj tuaj, thiab ntau yam txheej txheem kev lag luam.

Xaus lus

Cov yeeb nkab carbon steel uas muaj kauv sib txuas, xws liX42 SSAW yeeb nkab, tau hloov pauv txoj kev vuam yeeb nkab hlau, coj ntau yam txiaj ntsig rau ntau yam lag luam. Lawv lub zog, kev ruaj khov, kev siv nyiaj tsim nyog thiab qhov tseeb ntawm qhov ntev ua kom muaj kev ruaj khov ntawm cov qauv hauv ntau yam kev siv. Lub peev xwm los tiv taus qhov siab heev, kub thiab qhov chaw corrosive ua rau nws zoo tagnrho rau kev xa roj thiab roj, kev muab dej thiab lwm yam kev lag luam. Yog li ntawd, thaum nws los txog rau kev vuam yeeb nkab hlau, kev siv cov kav hlau carbon welded tseem yog qhov kev daws teeb meem txhim khu kev qha thiab ua tau zoo kom ntseeg tau tias cov khoom siv kav ntev thiab ruaj khov.

Kev Ntsuas Hydrostatic

Txhua qhov ntev ntawm cov yeeb nkab yuav tsum tau kuaj los ntawm tus neeg tsim khoom kom muaj lub zog hydrostatic uas yuav tsim cov kev ntxhov siab hauv phab ntsa yeeb nkab tsis pub tsawg dua 60% ntawm qhov tsawg kawg nkaus ntawm qhov kub thiab txias. Lub zog yuav tsum txiav txim siab los ntawm cov qauv hauv qab no:
P=2St/D

Kev Hloov Pauv Uas Tso Cai Hauv Qhov Hnyav thiab Qhov Ntev
