Lub installation ntawmcarbon steel kavfeem ntau yuav tsum ua raws li cov xwm txheej hauv qab no:

1. Cov kev paub txog kev tsim vaj tsev nyob hauv pipeline yog tsim nyog thiab ua tau raws li qhov yuav tsum tau ua;
2. Siv cov cuab yeej sib dhos kom txuas nrog cov kav dej thiab kho nws;
3. Cov txheej txheem cuam tshuam uas yuav tsum tau ua tiav ua ntej kev teeb tsa cov kav dej, xws li ntxuav, degreasing, sab hauv los tiv thaiv corrosion, hauv ob sab phlu, thiab lwm yam.
4. Cov khoom siv yeeb nkab thiab cov yeeb nkab txhawb nqa tau tsim nyog tau txais kev paub thiab muaj cov ntaub ntawv tseem ceeb;

5. Xyuas seb cov yeeb nkab fittings, cov kav dej, li qub, thiab lwm yam puas yog raws li cov ntaub ntawv tsim, thiab ntxuav cov khib nyiab sab hauv; thaum cov ntaub ntawv tsim qauv muaj kev tu tshwj xeeb rau sab hauv ntawm lub raj xa dej, nws qhov kev ua tau zoo ua tau raws li qhov xav tau ntawm cov ntaub ntawv tsim.

Txoj kev nqes hav thiab kev taw qhia ntawm lub raj xa dej yuav tsum ua raws li cov qauv tsim. Cov yeeb nkab nqes hav tuaj yeem hloov kho los ntawm kev teeb tsa qhov siab ntawm lub bracket lossis cov hlau rov qab phaj nyob rau hauv lub bracket, thiab lub boom bolt tuaj yeem siv los kho. Lub phaj nraub qaum yuav tsum tau welded nrog cov khoom siv kos duab lossis cov qauv hlau, thiab yuav tsum tsis txhob sib tsoo ntawm cov yeeb nkab thiab kev txhawb nqa.

Thaum cov yeeb nkab ncaj nraim txuas nrog cov yeeb nkab loj, nws yuav tsum tau me ntsis inclined nrog cov kev taw qhia ntws ntawm qhov nruab nrab.

Flanges thiab lwm yam txuas yuav tsum tau muab tso rau hauv qhov chaw uas kev saib xyuas yooj yim, thiab tsis tuaj yeem txuas nrog cov phab ntsa, pem teb lossis cov yeeb nkab txhawb nqa.

Cov kav dej degreased, cov yeeb nkab fittings thiab li qub yuav tsum tau soj ntsuam nruj me ntsis ua ntej kev teeb tsa, thiab yuav tsum tsis muaj sundries rau sab hauv thiab sab nrauv.

Yog tias pom cov khib nyiab, nws yuav tsum tau degreased dua, thiab muab tso rau hauv kev teeb tsa tom qab dhau qhov kev tshuaj xyuas. Cov cuab yeej thiab ntsuas cov cuab yeej siv hauv kev teeb tsa ntawm cov kav dej degreasing yuav tsum tau degreased raws li qhov yuav tsum tau ua ntawm cov khoom degreasing. Cov hnab looj tes, khaub ncaws thiab lwm yam khoom siv tiv thaiv uas siv los ntawm cov neeg ua haujlwm yuav tsum tsis muaj roj.

Thaum txhim kho cov kav dej faus, kev ntsuas dej yuav tsum tau ua thaum cov dej hauv av lossis cov yeeb nkab trench sau cov dej. Tom qab qhov kev sim siab thiab kev tiv thaiv corrosion ntawm cov kav dej hauv av, qhov kev lees paub ntawm kev ua haujlwm zais cia yuav tsum tau ua kom sai li sai tau, cov ntaub ntawv zais cia yuav tsum tau sau rau hauv, rov qab ua haujlwm rau lub sijhawm, thiab muab ntim rau hauv txheej.

Casing lossis culvert tiv thaiv yuav tsum tau ntxiv thaum cov kav dej hla hauv pem teb, phab ntsa, ducts lossis lwm yam khoom. Cov yeeb nkab yuav tsum tsis txhob welded nyob rau hauv lub casing. Qhov ntev ntawm phab ntsa bushing yuav tsum tsis txhob tsawg tshaj li lub thickness ntawm phab ntsa. Hauv pem teb casing yuav tsum yog 50 hli siab tshaj hauv pem teb. Cov kav dej los ntawm lub ru tsev yuav tsum muaj lub xub pwg tsis muaj dej thiab lub kaus mom los nag. Cov yeeb nkab thiab cov qhov khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob.

Meters, siab conduits, flowmeters, regulating chambers, flow orifice plates, thermometer casings thiab lwm yam cuab yeej cuab tam uas txuas nrog lub raj xa dej yuav tsum tau muab ntsia rau tib lub sij hawm raws li cov kav dej, thiab yuav tsum tau ua raws li cov kev cai rau kev teeb tsa.

Nruab cov kav dej txuas ntxiv, ntsuas qhov ntsuas qhov tob tob thiab saib xyuas cov kav dej raws li cov ntaub ntawv tsim thiab kev lees paub kev tsim kho.

Kev kho corrosion yuav tsum tau nqa tawm ntawm faus steel kav ua ntej kev teeb tsa, thiab kev tiv thaiv corrosion yuav tsum tau them sai sai rau lub sijhawm teeb tsa thiab kev thauj mus los. Tom qab qhov kev ntsuam xyuas lub raj xa dej tau tsim nyog, kev kho los tiv thaiv corrosion yuav tsum tau nqa tawm ntawm lub vuam seam.

Kev sib koom ua ke, qhov siab, qhov sib nrug thiab lwm qhov kev teeb tsa ntawm lub raj xa dej yuav tsum ua raws li cov qauv tsim, thiab qhov sib txawv yuav tsum tsis txhob dhau qhov kev cai.
