2. Thov
Txoj kev nqes hav thiab gradient ntawm lub raj xa dej yuav tsum ua kom tau raws li cov qauv tsim;txoj kab nqes ntawm cov kav xa dej tuaj yeem hloov kho los ntawm cov hlau rov qab phaj hauv qab kev txhawb nqa, thiab lub hanger tuaj yeem hloov kho los ntawm boom bolt;lub phaj rov qab yuav tsum tau welded nrog cov khoom siv kos duab lossis cov qauv hlau, Nws yuav tsum tsis txhob raug ntes ntawm cov yeeb nkab thiab kev txhawb nqa.
Flanges, welds thiab lwm yam txuas yuav tsum tau npaj kom yooj yim rau kev soj ntsuam thiab kho, thiab yuav tsum tsis txhob nyob ze rau ntawm phab ntsa, pem teb lossis cov yeeb nkab.
Thaum lub raj xa dej hla hauv pem teb slab, yuav tsum tau nruab ib lub raj tiv thaiv, thiab lub raj tiv thaiv yuav tsum yog 50 hli saum av.
Thaum lub raj xa dej hla hauv pem teb slab, yuav tsum tau nruab ib lub raj tiv thaiv, thiab lub raj tiv thaiv yuav tsum yog 50 hli saum av.
Daim ntawv thiab qhov siab ntawm kev txhawb nqa thiab hanger yuav tsum ua raws li qhov yuav tsum tau ua ntawm cov duab kos, thiab kho txoj haujlwm thiab kho txoj kev yuav tsum ua raws li tus qauv tsim thiab ua kom tiaj tus thiab ruaj khov.
Kab ntawm kab rov tav lossis ntsug kav dej yuav tsum zoo huv si, thiab lub valve installation txoj haujlwm ntawm cov kab ntawm cov kav dej yuav tsum zoo ib yam.
3. Kev teeb tsa
Pipeline installation yog muab faib ua systems thiab pieces.Lub ntsiab yeeb nkab ua ntej, ces cov ceg yeeb nkab.Cov ceg yeeb nkab los ntawm cov yeeb nkab loj yuav tsum tau muab tso rau tom qab cov yeeb nkab tseem ceeb tau muab tso rau.Century Star tau qhia tias cov raj xa dej txuas nrog cov khoom siv yuav tsum tau ua tom qab cov khoom siv tau zoo.
Lub flange kev twb kev txuas yuav tsum yog concentric nrog lub raj xa dej, thiab cov flanges yuav tsum yog tib yam.Qhov sib txawv yuav tsum tsis txhob ntau tshaj 1.5% ntawm sab nraud ntawm flange thiab tsis ntau tshaj 2 hli.Lub qhov ntsia liaj qhov rooj yuav tsum xyuas kom meej tias cov bolts tuaj yeem nkag mus tau ywj pheej, thiab cov bolts yuav tsum tsis txhob nkag los ntawm txoj kev yuam..
Ob lub dav hlau ntawm lub gasket yuav tsum tiaj tus thiab huv si, thiab yuav tsum tsis txhob muaj hluav taws xob khawb.
Flange kev twb kev txuas yuav tsum siv bolts ntawm tib lub specification, thiab cov kev taw qhia ntawm installation yuav tsum yog tib yam.Thaum xav tau gaskets, txhua lub bolts yuav tsum tsis txhob ntau tshaj ib, thiab cov bolts thiab ceev tom qab zawm yuav tsum tau yaug.
