Cov kauj ruam ntawm cov pipeline kev teeb tsa engineering

1. Cov kauj ruam

Raws li cov chaw nce siab muab los ntawm cov pej xeem engineering, Mark Qhov nce Datum kab ntawm phab ntsa thiab lub hauv paus yuav tsum tau nruab nrog; Nruab qhov pipeline bracket thiab khuam khawb ncaws raws li daim duab thiab tooj; Nruab lub raj xa hluav taws raws li cov raj xa hluav taws xob teeb tsa thiab tus naj npawb tshiab ntawm cov raj xa dej; Kho thiab qib ntawm txoj kab nqes ntawm cov yeeb nkab, txhim kho cov yeeb nkab txhawb nqa, thiab txoj haujlwm cov yeeb nkab.

Txoj kev nqes hav thiab gradient ntawm cov raj xa dej yuav tsum ua kom tau raws li cov qauv tsim; Txoj kab nqes ntawm cov raj xa dej tuaj yeem hloov kho los ntawm cov hlau rov qab sib txuas hauv kev txhawb nqa, thiab tus pas tua tsiaj tuaj yeem hloov kho los ntawm kev ua yeeb yam bunt; Lub thawv thaub qab yuav tsum tau welded nrog cov kab kos lossis cov qauv hlau, nws yuav tsum tsis txhob ntes ntawm cov yeeb nkab thiab kev txhawb nqa.

Flanges, Welds thiab lwm qhov sib txuas yuav tsum tau npaj kom yooj yim tshuaj xyuas thiab kho tau yooj yim, thiab yuav tsum tsis txhob ze rau ntawm phab ntsa, hauv pem teb lossis cov yeeb nkab ncej.

Thaum twg cov raj xa dej mus rau hauv av slab, lub raj tiv thaiv yuav raug teeb tsa, thiab lub raj tiv thaiv yuav tsum muaj 50mm saum toj no hauv av.

Thaum twg cov raj xa dej mus rau hauv av slab, lub raj tiv thaiv yuav raug teeb tsa, thiab lub raj tiv thaiv yuav tsum muaj 50mm saum toj no hauv av.

Daim foos thiab nce ntawm kev txhawb nqa thiab cov kws tua tsiaj yuav tsum ua raws li cov duab kos, thiab kho txoj haujlwm thiab kho cov qauv yuav tsum ua raws li cov qauv thiab ua kom ruaj khov.

Cov kab ntawm kab rov tav lossis ntsug yuav tsum zoo, thiab lub valve installation txoj haujlwm ntawm cov kab ntawm pipelines yuav tsum muaj sib xws.

3. Nruab

Xa hluav taws xob tau muab faib ua cov tshuab thiab tej daim. Lub ntsiab yeeb nkab ua ntej, tom qab ntawd lub ceg yeeb nkab. Lub ceg yeeb nkab los ntawm cov yeeb nkab tseem ceeb yuav tsum tau nruab tom qab lub xaim loj yog qhov chaw. Lub Hnub nyoog Lub Hnub Qub tau qhia tias cov raj xa hluav taws xob txuas nrog cov khoom siv yuav tsum tau nqa tawm tom qab cov khoom siv yog theem.

Lub flange txuas yuav tsum yog concelric nrog cov raj xa dej, thiab cov flanges yuav tsum tau ua ke. Qhov txawv txav yuav tsum tsis txhob muaj ntau tshaj li 1.5% ntawm txoj kab uas hla ntawm lub flange thiab tsis ntau tshaj 2 hli. Cov tw lub qhov rooj yuav tsum xyuas kom meej tias cov bolts tuaj yeem nkag mus dawb paug, thiab cov bolts yuav tsum tsis txhob nkag los ntawm txoj kev yuam. Cov.

Ob lub dav hlau ntawm lub gasket yuav tsum yog tiaj thiab huv si, thiab yuav tsum tsis muaj tsis muaj kev khawb.

Flange kev sib txuas yuav tsum tau siv bolts ntawm tib cov lus tshwj xeeb, thiab kev teeb tsa kev teeb tsa yuav tsum zoo ib yam. Thaum cov gasnets xav tau, txhua qhov yeeb yaj kiab yuav tsum tsis pub tshaj ib qho, thiab cov bolts thiab txiv ntoo tom qab zawm.
