Gas Pipeline Tej Yam Uas Muaj Teeb Meem

Nyob rau hauv ib txwm muaj xwm txheej, cov roj raug thauj mus rau hauv lub kaw lus kaw, thaum lub kaw lus tsis ua haujlwm ua rau kev tswj xyuas cov pa xau, cov pa roj carbon monoxide yog sib xyaw nrog huab cua los tsim cov roj tawg kom ncav cuag qhov txwv tsis pub tawg lossis cov ntsiab lus ntawm cov dej yuav tua. tawg.

1. Cov khoom siv hauv cov kav dej lossis cov khoom siv vuam tsis raug.Cov yeeb nkab tsis zoo tuaj yeem ua rau cov kav dej muaj zog feem ntau yog cov kab nrib pleb lossis tawg, kev tsim kho zoo, tab sis tawm, qhov tsis zoo ntawm cov welded yeeb nkab pob qij txha los yog qhov kawg ntawm kev nkag mus, ua rau cov yeeb nkab lub zog tsis txaus, koj tuaj yeem tswj tsis tau cov kev ua haujlwm zoo.Uas tshwm sim nyob rau hauv lub natural gas xau, ua rau muaj hluav taws kub sib tsoo.

2. Cov yeeb nkab hauv qhov chaw hnav thiab corrosion.Cov roj uas muaj plua plav xws li xuab zeb, xeb, cov khoom siv tsis zoo nrog cov huab cua ntws, koj tuaj yeem hnav cov kav dej puas, qhov project ntawm cov pa roj carbon monoxide muaj C02, CO: acidic gas yaj hauv dej los ua H: CO ntawm hlau Muaj qee yam corrosive.Yog hais tias cov dej dew point ntawm qhov tsis ua hauj lwm los yog kev ntsuam xyuas siab pigging tsis zoo kom qhuav raj lub cim xeeb dej generated nyob rau hauv corrosion, corrosion loj ua rau pipeline puas, ua rau muaj kev huam yuaj.

3. Sab nrauv ntawm cov yeeb nkab corrosion.Vim tias cov raj xa dej sab nraud txheej hauv kev thauj mus los, kev tsim kho kev puas tsuaj.Yog tsis muaj kev kho kom raws sijhawm lossis tsis tuaj yeem ua tau raws li qhov xav tau los tiv thaiv corrosion, pipeline cathodic tiv thaiv kev ua haujlwm tsis ua haujlwm, cov yeeb nkab tso cov av muaj zog corrosive nyob ib ncig ntawm cov cag ntoo los tiv thaiv corrosion ua rau muaj kev sib tsoo.Nyob ze ntawm lub raj xa hluav taws xob muaj cov kab hluav taws xob sib txuas, hluav taws xob railway,roj kav dejthiab cov kav xa hluav taws xob sib txuas lossis cov chaw faib khoom sib txawv, cov kav xa hluav taws xob yooj yim faus ze ntawm qhov tsis muaj zog tam sim no ua rau muaj kev phom sij rau cov kav dej, uas ua rau cov dej xau, hluav taws kub, tawg thiab lwm yam xwm txheej.

4. Kev ntxhov siab tawg.Lub xub ntiag ntawm residual stresses nyob rau hauv cov yeeb nkab manufacturing txheej txheem, muaj ib tug kub qhov sib txawv ntawm qhov kub thiab txias kev khiav hauj lwm kub ntawm pipeline tsim, ua rau lub pipeline raws thermal stress yog generated nyob rau hauv lub axial kev taw qhia, yuav ua rau rupture ntawm cov yeeb nkab.

5. Cov kav dej muab tso rau hauv kev ua haujlwm.Thaum lub raj xa dej tau muab tso rau hauv kev ua haujlwm, pigging tsis ua kom qhuav, cov dej huv uas seem hauv cov yeeb nkab, yuav ua kom cov kav xa dej kom nrawm, cov khoom seem hauv cov kav dej yuav nrawm li qub, cov khoom siv hnav thiab cov khoom siv corrosion, ua rau muaj kev phom sij ntau ntxiv.

Kev tiv thaiv thiab kev tiv thaiv hluav taws
Cov kev ntsuas tseem ceeb yog: (I) tswj thiab tshem tawm cov khoom siv hluav taws xob;(2) nruj me ntsis tswj qhov zoo ntawm cov cuab yeej, xaiv qhov tsim nyog kev txhawj xeeb ntau dhau, cais, ntws, siab, ntsuas kub;(3) ua ntej commissioning ntawm lub raj xa dej siab yuav tsum tau kuaj;(4) tsis tu ncua xyuas thiab tu cov cuab yeej siv, ntsuas ntsuas;(5) nyob rau hauv qhov chaw nres tsheb los tsim ib qho chaw nres tsheb hluav taws xob, cov cim kev phom sij rau qhov chaw ua haujlwm;(6) kev txhim kho cov kev cai thiab cov kev cai thiab cov txheej txheem kev nyab xeeb, cov txheej txheem nruj nruj kom tsis txhob muaj kev sib tsoo Lub sijhawm ua haujlwm ua rau muaj cov pa roj paug;(7) ua raws li kev soj ntsuam xyuas, txheeb xyuas cov teeb meem thiab kev kho raws sij hawm: (8) pigging Clear txhaj dej kho ua ntej cov khoom khib nyiab yuav tsum tau ntxuav tsis tu ncua, saib xyuas cov ntsiab lus ntawm cov hlau.
