1.Iimeko kunye namalungiselelo oVavanyo loxinzelelo
1.1 Ukwakhiwa kwenkqubo yombhobho kugqityiwe, kwaye ihlangabezana neemfuno zoyilo kunye neenkcukacha.
1.2 Umsebenzi we-welding ugqityiwe emva kokuba i-rack yokuxuba kunye ne-pipe rack ifakwe.Ukufunyanwa kwe-ray kuye kwafikelela ngokupheleleyo kwiinkcukacha zokuyila kwaye kwadlula ukuhlolwa.I-welds kunye nezinye iindawo zokuhlola ekufuneka zivavanywe azipeyintwa kwaye zifakwe i-insulated.
1.3 I-gauge yoxinzelelo lovavanyo iqinisekisiwe, kwaye ukuchaneka ngamanqanaba e-1.5.Ixabiso elipheleleyo letafile kufuneka libe yi-1.5 ukuya ku-2 amaxesha alinganiswe kuxinzelelo oluphezulu.
1.4 Phambi kovavanyo, awukwazi ukuthatha inxaxheba kwisistim yovavanyo, izixhobo kunye nezixhobo, kwaye wongeze ileyibhile yepeyinti emhlophe eneleyibhile yepeyinti emhlophe enepleyiti eyimfama.
1.5Amanzi kufuneka asetyenziswe ukucoca amanzi, kwaye umxholo we-chloride emanzini akufanele udlule i-25 × 10-6 (25ppm).
1.6Ukomelezwa kombhobho okwethutyana kwiimvavanyo kufuneka kuqinisekiswe kwaye kuthembeke emva kokuhlolwa.
1.7Jonga ukuba ingaba zonke iivalve ezikumbhobho zivuliwe na, nokuba iipads zongeziwe, kwaye umise umbindi wevalve wondoqo wevalve, uze uwumise ngokutsha de ube uvuthelwe.
2.Inkqubo yoVavanyo lwePipeline yoVavanyo lweNkqubo
2.1.Uxinzelelo lovavanyo lombhobho ngamaxesha e-1.5 kuxinzelelo loyilo.
2.2.Xa umbhobho kunye nezixhobo zivavanywa njengenkqubo, uxinzelelo lovavanyo lombhobho lulingana okanye lungaphantsi koxinzelelo lovavanyo lwesixhobo.Undoqo
2.3.Xa inaliti yamanzi yenkqubo, umoya kufuneka uphelelwe.Indawo yokukhutshwa komoya kufuneka ibe kwindawo ephezulu yombhobho kwaye yongeze ivalve yokukhupha.
2.4.Imibhobho enezikhundla ezinkulu kufuneka ilinganiswe kuxinzelelo lovavanyo lovavanyo oluphakathi.Uxinzelelo lovavanyo lombhobho wolwelo kufuneka lube phantsi koxinzelelo lwendawo ephezulu, kodwa eyona ndawo isezantsi yeyona ndawo isezantsi mayingagqithi ukunyamezela ukubunjwa kwemibhobho.
2.5.Xa uxinzelelo lovavanyo, ukunyusa kufuneka kwenziwe kancinci.Emva kokuba uxinzelelo lovavanyo lufikelelwe, uxinzelelo lwexinzelelo kufuneka lube yimizuzu eyi-10.Ngaphandle kokuvuza, akukho deformation ifanelekile, kwaye ke uxinzelelo lovavanyo luyancitshiswa kuxinzelelo loyilo.Undoqo
2.6.Emva kokuba uvavanyo luphelile, ipleyiti eyimfama kufuneka isuswe ngexesha lokukhupha amanzi.Ngexesha lokukhutshwa kwamanzi, uxinzelelo olubi kufuneka luthintelwe, kwaye akukho manzi angakhutshwa naphi na.Xa ukuvuza kufunyenwe ngexesha lenkqubo yovavanyo, akuvumelekanga ukunyangwa ngoxinzelelo.Emva kokuphelisa iziphene, uvavanyo kufuneka luphinde luvavanywe.
2.7.Uvavanyo lokuvuza lwenziwa emva kokuba uvavanyo loxinzelelo lufanelekile, kwaye uvavanyo oluphakathi luxinzelelwe ngumoya oxinzelelweyo.
2.8.Uxinzelelo lovavanyo lokuvuza luxinzelelo loyilo.Uvavanyo lokuvuza kufuneka lugxile ekujongeni unobumba wokuzalisa.I-flange okanye intambo idityaniswe kwivalve engenanto, ivalve yokukhupha, kunye nevalve yokukhupha amanzi.
3. Yenza umbhobho wokuvuthela nokucoca
3.1.Iimfuno zeteknoloji
3.1.1 Umbhobho wenkqubo kufuneka uvuthelwe kwaye ucocwe ngokwamacandelo (okubhekiselwa kuwo njengokuvuthela).
3.1.2 Indlela yokuvuthela imiselwa ngokweemfuno zombhobho, indawo yokusebenza, kunye nokungcola okuphezu kombhobho.Ukulandelelana kokuvuthela ngokuqhelekileyo kuqhutyelwa ngokulandelelana ngokulandelelana komphathi, ukuxhasa, kunye nokukhupha imibhobho.
3.1.3 Phambi kokuvuthela, isixhobo esikwisistim kufuneka sikhuselwe, kwaye ibhodi yepore, ivalve elawula isihluzo kunye nondoqo wevalve kufuneka ichithwe, kwaye zigcinwe ngokufanelekileyo.
3.1.4 Ngexesha lokuvuthela, ii-ducts kufuneka zingangeni kwisixhobo, kwaye izitho ezivuthelwe ngaphandle kwesixhobo kufuneka zingangeni kumbhobho.
3.1.5 Izixhobo kunye nemibhobho ekungavumelekanga ukuba ihlanjwe kufuneka ibekwe yodwa kwisixokelelwano sokuvuthela.
3.1.6 Umbhobho wokuvuthela kufuneka ube nokuhamba okwaneleyo.Uxinzelelo lokuvuthela akufunekanga ludlule kuxinzelelo loyilo.Umyinge wokuhamba ngokubanzi awukho ngaphantsi kwe-20m/s.Xa uvuthela, sebenzisa isando somthi ukunkqonkqoza ityhubhu.Musa ukulimaza ityhubhu.
3.1.7 Qwalasela ukuqina kwesebe lombhobho kunye nendawo yokuxhoma phambi kokuvuthela, kwaye ukuqinisa kufuneka kunikelwe ukuba kuyimfuneko.
3.2.Ukuvuthela kwemibhobho, indlela yokucoca
3.2.1 Ukugungxulwa kwamanzi: Indawo yokusebenza ngumbhobho wenkqubo yamanzi.Ukuhlanjululwa kwamanzi kunokufikelela kubuninzi bokuhamba okanye kungabi ngaphantsi kwe-1.5m/s kumbhobho.Umbala wamanzi athunyelwa ngaphandle kunye nokungafihli kuyahambelana nokuhlolwa okubonakalayo ekungeneni.Emva kokuba umbhobho ufanelekile, amanzi kufuneka aphelelwe ngexesha.
3.2.2 Ukuvuthuza komoya: Indawo yokusebenza ngumbhobho werhasi.Nabani na odibana nevalve kufuneka aqhaqhe iflenge yangaphambili kwaye wongeze ibhafu, aze ayimise ngokutsha emva kokuba umbhobho uvuthelwe.Uxinzelelo kufuneka lungabi ngaphezu koxinzelelo loyilo lwesitya kunye nombhobho, kwaye izinga lokuhamba akufanele libe ngaphantsi kwe-20m / s.Ngexesha lenkqubo yokuvuthela komoya, xa umsi obonakalayo ukhupha umsi kunye nothuli, ibhodi ekujoliswe kuyo yokhuni yokuhlolwa kwepeyinti emhlophe ibekwe kwi-exhaust port, kwaye akukho mhlwa, uthuli, umswakama kunye nolunye udoti kwibhodi ekujoliswe kuyo yemizuzu emi-5.
3.2.3 Ukuvuthela ngomphunga: Indawo yokusebenza iskenwa ngemibhobho yomphunga ukuze ifumane imibhobho yomphunga.Phambi kokuba umphunga uvuthelwe, ityhubhu efudumeleyo kufuneka inyuswe kancinane ukuze ivuthelwe, ize iphole ngokwendalo ngokwendalo.Umlomo wendawo yokukhupha umphunga ujonge phezulu, kwaye ilogo ibambe amehlo.Ububanzi bombhobho wokukhupha akufanele bube buncinci kunobubanzi bombhobho ovuthelayo.Imigangatho yokufaneleka: buyisela ibhodi ekujoliswe kuyo kabini ngokulandelelana.Phantsi kweemeko zazo zonke iziqinisekiso), sisiqinisekiso sokuskena.
3.2.4 Ukusetwa ngokutsha kwemibhobho: Emva kokuba uvavanyo lwemibhobho kunye nokuvuthela lufanelekile, ibhodi engaboniyo kufuneka isuswe ngexesha elifanelekileyo ngokweerekhodi, kunye nevalve elawulayo elawulayo, ukumisa undoqo wevalve, isixhobo sesixhobo.
