Hauv thaj teb ntawm raj xa dej engineering, taub qab welded yeeb nkab fittings ua ib lub luag haujlwm tseem ceeb. Sib txawv ntawm cov pob tw-Welded cov yeeb nkab fittings sib txawv hauv ntau yam, thiab nkag siab cov kev sib txawv no yog qhov tsim nyog rau kev xaiv thiab siv.
Ua ntej tshaj plaws, los ntawm cov kev pom ntawm tsos thiab qauv, taub qab-welded lauj kaub tais tais thiab pob tw-welded tees txawv txawv. Taub Hau-Welded lauj tshib feem ntau yog siv los hloov cov kev taw qhia ntawm cov raj xa dej. Lawv cov duab nthuav qhia ib qho nkhaus arc, uas tuaj yeem ua rau cov raj xa dej tig rau ntawm lub kaum sab xis tshwj xeeb kom tau raws li kev ua kom sib txawv. Cov pob tw-welded Tees siv rau ceg sib txuas ntawm cov raj xa khoom. Lawv muaj peb txoj kev cuam tshuam, uas tuaj yeem faib cov kwj mus ua ob ntws lossis sib koom ua ke rau hauv ib qho kwj deg.
Thib ob, tseem muaj qhov sib txawv ntawm cov hau kev sib txuas thiab kev sib khi. Cov pob tw-Welded yeeb nkab fittings feem ntau yog txuas rau pipelines los ntawm vuam, tab sis vuam yuav tsum muaj cov yeeb nkab sib txawv tsis zoo ib yam. Piv txwv li, lub vuam ib feem ntawm cov pob tw-welded flange thiab cov raj xa hluav taws xob thiab cov raj xa dej thiab kev sib khi ntawm cov kev sib txuas thiab tiv thaiv kom tsis txhob muaj kua dej. Thaum pob tw-vuam redlucers, nws yog ib qhov tsim nyog yuav kom ntseeg tau tias kev hloov vuam ntawm cov hlab yeeb sib txawv yog qhov zoo thiab ntuj kom ua tiav cov kua dej du.
Tsis tas li ntawd, los ntawm cov kev pom ntawm kev siv ua haujlwm, txhua hom pob tw-Welded cov yeeb nkab fittings muaj nws tus yam ntxwv. Taub hau-welded rab koob yuav tsum yog siv los tswj cov kua dej, thiab cov℃ntawm kev qhib thiab kaw ntawm lub valve raug hloov los ntawm kev nce thiab txo qis lub valve qia; Thaum pob tw-welded rooj vag valves ua kom pom tseeb rau kev qhib thiab kaw cov nplaim dej raws. Thaum lub rooj vag tau tsa tag nrho, cov kua dej tuaj yeem dhau dawb.
Hauv kev siv hluav taws xob tiag tiag, kev nkag siab raug ntawm cov kab sib txawv hauv cov kab ke tsim nyog raws li cov kev lag luam tsim nyog raws li kev ua haujlwm kom nyab xeeb thiab ruaj khov ntawm cov raj xa hluav taws xob.
