Qhov tseem ceeb ntawm kauv submerged Arc Yeeb hauv API 5L Kab Yeeb Nkab Cov Yeeb Nkab Hluav Taws Xob
Kev siv cov pa roj carbon xaim hluav taws xob vuam, tshwj xeeb tshaj yog muab cov yeeb nkab kauv submerged arc Welded yeeb nkab, yog qhov tseem ceeb los ua kom ntseeg tau tus cwj pwm kev ncaj ncees thiab kev ntseeg tau ntawmAPI 5L Kab Yeeb NkabCov. Txoj kev vuam vuam no tsim ib qho kev sib tw thiab ntev txoj cai ntawm cov pa roj carbon monoxide, uas yog ib qho tsim nyog los tiv thaiv cov haujlwm siab thiab kev ntsuas lub ntsej muag pipelines.
Muab kauv submerged arc cov leeg yog tsim los ntawm cov txheej txheem vuam vuam tshwj xeeb uas lub vuam arc yog muab raus hauv qab ntawm flux. Qhov no tsim ib tug tsis muaj dab tsi, siab zoo weld thiab txuas qhov ntev ntawm cov yeeb nkab. Kev siv ntawm cov vuam vuam hauv cov pa roj carbon hlau vuam ntawm api 5L kab yeeb nkab kom muaj zog thiab ruaj cov kev xav tau ntawm cov roj thiab roj kev lag luam.

Ntxiv nrog rau vuam zoo, ssaw cov yeeb nkab muaj ob peb lwm qhov zoo uas ua rau nws tseem ceeb hauv api 5l kab yeeb kev siv. Tus muab kauv muab cov raj xa hluav taws xob muab cov raj xa hluav taws xob muab cov khoom siv hloov tau zoo dua thiab versatility, ua rau nws yooj yim rau kev sib txawv hauv lub nroog thiab cov nyom thaum pipeline kev tsim kho.
Tsis tas li ntawd, kauv submerged arc hlab muaj peev xwm ua kom haum lub diamerers loj dua, ua rau lawv zoo rau kev thauj cov roj thiab roj zoo. Nws lub peev xwm los daws cov kua loj ntawm cov kua thaum tswj cov qauv kev ncaj ncees ua rau kev xaiv kev ncaj ncees rau API 5L Kab Kab Kab.
Lwm qhov zoo ntawm kauv submerged arc hlab yog lawv cov nqi-ua hauj lwm zoo. Cov txheej txheem vuam ua kom zoo thiab muaj peev xwm tsim cov kav dej loj dua ua rau nws muaj txiaj ntsig zoo rau kev tsim kho pipeline. Qhov no yog qhov tshwj xeeb tshaj yog nyob rau hauv cov roj thiab roj kev lag luam, qhov twg xa hluav taws xob, qhov twg xa hluav taws xob kev tsim kho thiab kev txij nkawm tuaj yeem yog qhov siv nyiaj tseem ceeb.
Kev siv ntawm kauv submerged arc welded kav rau hauv APP roj hmab yeeb nkab hloov pauv Nws cov vuam zoo, yoog raws thiab raug nqi zoo ua nws tseem ceeb ntawm cov roj thiab roj pipeline kev tsim kho.
Hauv cov ntsiab lus, SSAW cov yeeb nkab ua lub luag haujlwm tseem ceeb hauv cov pa roj carbon hlau vuam rau API 5L Kab Kab Kab. Nws cov vuam zoo, yoog raws thiab raug nqi zoo ua rau nws zoo tagnrho rau kev siv hluav taws xob hauv cov roj thiab roj kev lag luam. Los ntawm xaiv SSAW cov yeeb nkab, lub tuam txhab tuaj yeem ntseeg cov qauv kev ntseeg siab thiab kev ntseeg tau ntawm nws cov kab laum kab, cov kab ua kom zoo dua thiab txhim khu kev qha.
