Lub sijhawm xa khoom ntawm cov kav hlau no uas tus neeg siv khoom xaj yog 20 hnub, uas luv dua 15 hnub rau tus neeg siv khoom.
Niaj hnub no, cov neeg tshuaj xyuas tau ua tiav qhov kev tshuaj xyuas thiab yuav raug xa mus tag kis. Cov kav hlau no yogAPI 5L/ASTM A106 Qib B, nrog ntau yam lus qhia, suav nrog phab ntsa tuab ntawm 3.25, 3.54, 3.45 thiab lwm yam lus qhia.
Tom qab peb tau txais daim ntawv xaj tsim khoom lawm, peb mam li qhia cov duab ntawm cov yeeb nkab uas siv lub teeb, cov duab txau, cov duab sib sau ua ke thiab kev yuav cov hau yeeb nkab rau cov neeg siv khoom pom tiag tiag, ntsuas qhov tuab ntawm phab ntsa thiab txoj kab uas hla ntawm cov yeeb nkab rau cov neeg siv khoom, thiab thaij cov duab ntawm cov duab sib sau ua ke rau cov neeg siv khoom tom qab txau thiab sib sau ua ke. Hnub no peb tau txais kev tshuaj xyuas los ntawm cov neeg thib peb uas cov neeg siv khoom xa tuaj thiab tau txais kev pom zoo, uas yuav coj cov khoom no mus.
Tag kis, cov khoom no yuav raug thauj mus rau hauv cov thawv thiab xa mus rau qhov chaw nres nkoj thiab xa mus rau qhov chaw nres nkoj ntawm tus neeg siv khoom.
Qhov kev xa khoom no tau txuag peb cov neeg siv khoom 5 hnub ua haujlwm thiab ua rau lub sijhawm tos luv dua rau cov neeg siv khoom. Peb xav qhuas cov engineers, cov neeg ua haujlwm hauv ntau txoj haujlwm ua tiav, kev txheeb xyuas cov ntaub ntawv thiab kev xa khoom yooj yim, thiab cov neeg siv khoom txoj kev koom tes ua haujlwm!
Peb lub tuam txhab cov khoom tseem ceeb yog: Cov kav dej Boiler suav txog 40%; cov kav dej kab suav txog 30%; cov kav dej Petrochemical suav txog 10%; cov raj xa cua sov suav txog 10%; cov kav dej kho tshuab suav txog 10%.
