ib.Txoj kev deoxidation yog tsim raws li hauv qab no:
FF: Ua tiav cov hlau uas muaj nitrogen khi cov ntsiab lus kom txaus los khi muaj nitrogen (xws li min. 0,020% tag nrho Al lossis 0,015% soluble Al).
b.Tus nqi siab tshaj plaws rau nitrogen tsis siv yog tias cov tshuaj muaj pes tsawg leeg pom qhov tsawg kawg nkaus Al ntsiab lus ntawm 0,020% nrog qhov tsawg kawg nkaus Al / N piv ntawm 2: 1, lossis yog tias muaj lwm yam N-binding ntsiab.Cov ntsiab lus N-binding yuav tsum tau sau rau hauv Cov Ntaub Ntawv Tshawb Fawb.

Tsis tas li ntawd, hauv kev tiv thaiv hluav tawscov kav dej, kev siv kauv seam welded kav yog ib qho tseem ceeb los xyuas kom meej qhov kev nyab xeeb thiab kev cia siab ntawm lub system.Cov kav dej no tshwj xeeb tsim los tiv thaiv qhov kub thiab txias thiab tsim nyog siv rau hauv kev tiv thaiv hluav taws.Cov welded kev tsim kho ntawm kauv seam yeeb nkab ua kom ntseeg tau tias nws yog cov ntaub ntawv pov thawj thiab tuav cov txheej txheem kev ncaj ncees txawm tias nyob rau hauv cov xwm txheej hnyav, ua rau nws yog ib qho tseem ceeb ntawm kev tiv thaiv hluav taws thiab hluav taws tua hluav taws.

Ib qho ntawm cov txiaj ntsig tseem ceeb ntawmkauv seam welded yeeb nkabyog nws versatility thiab adaptability rau ntau yam kev siv.Cov kav dej no tuaj yeem tsim nyob rau hauv ntau yam diameters thiab thicknesses kom tau raws li qhov project tshwj xeeb.Tsis tas li ntawd, lawv tuaj yeem raug coated nrog cov ntaub ntawv tiv thaiv los txhim kho kev tiv thaiv corrosion thiab ncua lawv lub neej kev pab cuam, ua rau lawv haum rau siv nyob rau hauv ntau qhov chaw thiab tej yam kev mob.

Kauv seam welded kav muaj qhov zoo meej thaum nws los txog rau kev teeb tsa thiab kev saib xyuas.Lawv yog lub teeb yuag thiab hloov tau yooj yim, ua rau lawv yooj yim rau kev thauj mus los thiab ua haujlwm, txo lub sijhawm installation thiab nqi zog.Tsis tas li ntawd, nws qhov ntev, txuas ntxiv txo qis qhov kev xav tau ntawm kev sib txuas ntxiv, txo qhov kev pheej hmoo ntawm kev xau thiab ua kom muaj txiaj ntsig zoo dua thiab txhim khu kev qha cov kav dej.

Hauv kev xaus, kauv seam welded yeeb nkab yog ib qho tseem ceeb nyob rau hauv ntau yam lag luam, tshwj xeeb tshaj yog nyob rau hauv txias tsim welded lug thiabkab hluav taws kubdaim ntawv thov.Nws cov kev tsim kho ruaj khov, kev ua haujlwm siab thiab kev hloov pauv ua rau nws yog thawj qhov kev xaiv rau engineers, cov neeg cog lus thiab cov thawj tswj haujlwm.Txawm hais tias kev tsim cov qauv tsim muaj zog lossis tsim kev nyab xeeb thiab txhim khu kev tiv thaiv hluav taws, cov kav dej welded kauv yog ib qho kev daws teeb meem rau cov kev xav tau ntawm niaj hnub infrastructure thiab kev lag luam.
