ppr pipeline specifications, peb feem ntau hnov tias muaj 4 ceg thiab ceg. 4. Sab nraud txoj kab uas hla ntawm cov yeeb nkab 20mm, 6. Txheej txoj kab uas hla ntawm cov yeeb nkab 25mm. Hauv kev siv tiag tiag, cov dej ntws ntawm 6 ceg yeeb nkab yog me ntsis loj dua li ntawm 4 ceg yeeb nkab. Cov yeeb nkab tseem ceeb yog ntau tshaj 6 cov kav dej, thiab cov yeeb nkab ceg yog ntau tshaj 4 cov kav dej. Cov dej ntws tsis yog qhov zoo dua, txwv tsis pub nws yuav ua rau cov dej khib nyiab
LAYING OF ppr pipeline yuav tsum xaiv cov kav dej raws li qhov xwm txheej tiag tiag mus rau saum lossis mus qis. Cov hauv qab no yog qee qhov zoo thiab qhov tsis zoo ntawm kev sib piv: mus rau sab saum toj: qhov teeb meem tau pom thaum ntxov, nws kuj yog qhov yooj yim los ua cov dej hauv av ntawm chav dej, thaum muaj qhov dej xau, nws yuav tsis cuam tshuam rau cov neeg nyob ze hauv qab: tab sis kuj tseem muaj qhov teeb meem ntawm kev siv zog ua haujlwm, thiab kev saib xyuas yuav tsum tau tshem tawm lub qab nthab. Mus: txuag kev ua haujlwm, hauv kev ua haujlwm thiab cov yeeb nkab kom txuag tau tus nqi; Cov dej xau yog qhov nyuaj rau nrhiav, thiab hauv Circuit Court kuj mus rau rooj plaub yuav ua rau tsis ua haujlwm hauv Circuit Court; Nws tsis yog ib qho yooj yim mus nrhiav tau qhov to thaum lub sij hawm txij nkawm, uas yuav ua rau nws kim heev kev puas tsuaj; Nws kuj tseem ua rau muaj kev tsis sib haum xeeb hauv zej zog
