a. Cov txheej txheem Deagidation yog tsim raws li hauv qab no:
FF: Nkaus tua cov hlau uas muaj cov khoom siv nitrogen khi rau hauv cov nyiaj muaj peev xwm khi muaj nitrogen (piv txwv li min lossis 0,015% soluble al).
b. Tus nqi siab tshaj plaws rau Nitrogen tsis siv yog tias cov tshuaj lom neeg muaj pes tsawg leeg ntawm 0,020% nrog tsawg kawg AL / N piv txog 2: 1, lossis yog tias muaj lwm cov n-khi cov khoom n-khi tam sim no. Cov n-khi cov ntsiab yuav tsum tau sau cia hauv daim ntawv tshuaj xyuas.

Ib qho ntxiv, hauv kev tiv thaiv hluav tawslub xov khoom, kev siv cov kauv cov leeg sib tshuam welded kav yog qhov tseem ceeb los xyuas kom muaj kev nyab xeeb thiab kev ntseeg tau ntawm lub system. Cov kav dej no tau tsim tshwj xeeb los ua kom cov neeg tiv thaiv kom kub thiab ntsuas thiab haum rau siv hauv cov hluav taws tiv thaiv cov tshuab. Kev tsim kho welded ntawm kauv yeeb nkab kauv yeeb nkab xaim kom ntseeg tau tias nws yog cov txiaj ntsig zoo, ua rau muaj kev sib raug zoo ntawm hluav taws kub thiab hluav taws kub kev tiv thaiv thiab hluav taws kub.

Ib qho ntawm cov ntsiab lus tseem ceeb ntawmMuab kauv cov leeg welded yeeb nkabPuas yog nws cov versatility thiab kev yoog raws li rau ntau cov ntawv thov. Cov kav dej no tuaj yeem tsim cov diameters thiab thickinges kom tau raws li kev xav tau tshwj xeeb. Ib qho ntxiv, lawv tuaj yeem sib xyaw nrog cov ntaub ntawv tiv thaiv kom txhim kho corrosion tsis kam thiab ncua lawv lub neej, ua rau kev siv nyob rau hauv cov chaw sib txawv thiab cov xwm txheej.

Muab kauv Cov Kav Welded Pipes muaj qhov zoo meej thaum nws los txog rau kev teeb tsa thiab txij nkawm. Lawv yog lub teeb ci ntsa iab thiab hloov tau, ua rau lawv thauj khoom yooj yim thiab kov, txo cov nqi teeb tsa thiab cov nqi zog. Tsis tas li ntawd, nws ntev, txuas ntxiv ntev qhov kev xav tau rau kev sib txuas ntxiv, txo qis kev pheej hmoo ntawm cov dej xau thiab txhim khu kev qha piping kom muaj txiaj ntsig ntau dua thiab txhim khu kev qha.

Hauv kev xaus, kauv welded welded yeeb nkab yog ib qho tseem ceeb hauv kev lag luam ntau, tshwj xeeb tshaj yog nyob rau hauv kev tsim khaub ncaws welded thiabHluav taws yeeb nkab kabCov ntawv thov. Nws cov kev tsim kho ruaj khov, kev ua tau zoo thiab hloov kho nws qhov kev xaiv thawj rau engineers, cov thawj tswj hwm thiab cov thawj tswj haujlwm. Txawm hais tias lub tsev muaj zog lossis tsim kev tiv thaiv hluav taws kom nyab xeeb thiab txhim khu kev siv hluav taws xob muaj zog rau cov kev xav tau ntawm cov kev xav tau niaj hnub thiab kev lag luam.
