Qhov sib txawv ntawm welded thiab cov kav hlau tsis muaj seamless yog ib txoj haujlwm tseem ceeb rau txhua tus neeg ua haujlwm hauv kev lag luam hlau. Nrog ntau hom yeeb nkab hlau sib txawv hauv kev ua lag luam, nws yog ib qho tseem ceeb kom nkag siab txog cov txheej txheem thiab cov txheej txheem uas xav tau los txheeb xyuas hom yeeb nkab hlau uas siv lossis yuav. Tsab xov xwm no tham txog cov txheej txheem siv los txheeb xyuas cov yeeb nkab hlau, thaum tsom mus rauCov yeeb nkab carbon SSAW, cov yeeb nkab hlau txuas ua ke, thiab cov nqi carbon SSAW.
Ib qho ntawm txoj hauv kev tseem ceeb los sib txawv ntawm cov kav hlau welded los ntawmcov kav hlau tsis muaj seamlessyog xyuas seb txoj kev tsim khoom ntau lawm.Cov kav hlau tsis muaj qhov txuasyog tsim tawm yam tsis muaj kev vuam thaum cov kav hlau welded yog tsim los ntawm kev vuam cov hlau strips lossis cov phaj ua ke. Cov yeeb nkab carbon steel SSAW, piv txwv li, yog ua los ntawm kev sib txuas cov hlau kub-kuav los ntawm cov hlau dov ib puag ncig cov yob tsim los tsim cov kab sib dhos, uas tom qab ntawd vuam ua ke. Cov txheej txheem tsim khoom sib txawv tuaj yeem cuam tshuam rau cov khoom siv lub cev ntawm cov kav hlau.
Lwm txoj hauv kev los txheeb xyuas cov kav dej hlau yog saib ntawm qhov chaw ntawm cov kav dej. Tsis muaj cov kab sib txuas pom tseeb ntawm qhov chaw ntawmcov kav hlau tsis muaj seamless, thaum muaj cov kab sib txuas pom tseeb ntawm qhov chaw ntawm cov kav hlau welded. Cov kav hlau welded kauv muaj cov qauv kauv tshwj xeeb, uas ua rau lawv yooj yim kom paub qhov txawv ntawm lwm hom kav hlau. Tsis tas li ntawd, cov nqi carbon SSAW yuav cuam tshuam rau qhov zoo thiab cov yam ntxwv ntawm cov kav hlau.
Ntxiv rau cov txheej txheem uas tau tham saum toj no, cov txheej txheem kuaj tsis ua puas tsuaj (NDT) kuj tseem siv tau los txheeb xyuas cov kav hlau. Qee cov txheej txheem NDT nrov suav nrog Magnetic Particle Inspection (MPI), Ultrasonic Testing (UT) thiab Radiography. Cov txheej txheem no yog siv los txheeb xyuas txhua qhov tsis zoo lossis teeb meem hauv cov kav hlau yam tsis ua rau cov kav puas tsuaj.
Xaus lus, kev txheeb xyuas kom zoo ntawm cov kav hlau welded thiab seamless yog qhov tseem ceeb rau txhua tus neeg ua haujlwm hauv kev lag luam hlau. Carbon SSAW Steel Pipe, Spiral Welded Steel Pipe, thiab Carbon SSAW Price yog cov hom kav hlau nrov tshaj plaws niaj hnub no. Kev nkag siab txog cov txheej txheem siv los txheeb xyuas cov kav hlau no yog qhov tseem ceeb kom ntseeg tau tias kev xaiv thiab siv cov kav hlau cuam tshuam uas ua tau raws li cov kev xav tau tshwj xeeb ntawm ntau yam kev lag luam. Txhua tus neeg yuav lossis tus neeg siv kav hlau tuaj yeem tau txais txiaj ntsig los ntawm kev paub ntau yam txheej txheem txheeb xyuas thiab cov yam ntxwv ntawm ntau hom kav hlau kom ntseeg tau tias muaj txiaj ntsig zoo dua, tsim nyog thiab ua haujlwm tau zoo.
