Ngenxa yokuba uthutho lwemibhobho lufaneleke ngakumbi ukuthutha ioyile, igesi, ngoko ke, umbhobho wepetroleum kunye neshishini lepetrochemical wawusetyenziswa kakhulu.Owayesakuba yiPetrifaction Corporation ngonyaka i-oyile ekrwada eyi-120000000 T, eyona isetyenziswa yimibhobho;imveliso yonyaka yomphunga, amalahle, idizili 5000 yezigidi zeetoni, apho 80% ngezothutho imibhobho;isixhobo seshishini lepetrochemical, isixhobo sothutho lwemathiriyeli yeekhemikhali elulwelo okanye yerhasi luhamba ikakhulu ngombhobho ukugqibezela.Ngoko ke, amashishini e-petrochemical amashishini okwakhiwa kwenkunzi yonyaka kunye nemveliso kunye nokulungiswa zonke kufuneka zisebenzise inani elikhulu lombhobho wensimbi.Kodwa, ngenxa yomsebenzi weshishini le-petrochemical ubonakala ngobushushu obuphezulu kunye noxinzelelo oluphezulu, oluvuthayo kunye nokuqhuma, ngoko ke ukusetyenziswa kweetyhubhu zetsimbi kufuna ngqongqo kakhulu.

Ukuchasa ngokuthe tyeumbhobho wentsimbi weldinguphuhliso

Kwiminyaka yakutshanje, kukho umbhobho wentsimbi okumgangatho ophezulu okumgangatho ophezulu oza kuthatha indawo yendlela yophuhliso lweendleko eziphezulu, ikakhulu ngenxa yetekhnoloji yokuvelisa umbhobho odityanisiweyo rhoqo, ebonakaliswa kule miba ilandelayo:

(1) iteknoloji ye-desulfurization, ukwenzela ukuba umxholo wesulfure wensimbi uyancipha, uphucula umgangatho we-welding wepayipi yensimbi.

(2) itekhnoloji ye-vacuum degassing, iphucula ukucoceka kwentsimbi ye-tube engenanto, inciphisa ukufakwa, umgangatho we-weld seam uphucula.

(3) ngenxa yokongezwa kwe-V, i-Ti, i-Nb kunye nezinye izinto ezikhethekileyo, kunciphisa ukulingana kwekhabhoni, ukuqina kwensimbi, amandla kunye nezinye iimpawu ziphuculwe.

( 4) uphuhliso umcu intsimbi eshushu ukuqengqeleka iteknoloji, ukwanda ukuchaneka dimensional, ngoko ubungakanani umbhobho ukutenxa ukuncitshiswa.

( 5) ukuphuculwa kweendlela zokuhlola umgangatho, ezifana novavanyo lwe-ultrasonic nondestructive, umatshini wokuvavanya i-hydrostatic kunye nezinye izixhobo kufuneka zisetyenziswe, ukuqinisekisa umgangatho wemveliso yokugqibela.

Ukuxhathisa ngokuthe tye ukuwelda umbhobho wentsimbi osetyenziswa kwishishini lepetrochemical

Ukukhethwa kwamashishini ePetrochemical kumbhobho wentsimbi ngenxa yokuthwala uxinzelelo oluthile, olusetyenziswa ngokubanzi kulwelo olunombhobho wentsimbi ongenamthungo.Ukuxhathisa kombane umbhobho odityanisiweyo kunye nolwelo olunemibhobho yentsimbi engenamthungo umahluko, uneenzuzo ezicacileyo zoqoqosho, ikakhulu ezibonisa: utyalo-mali oluncinane;umatshini, idigri ye-automation iphezulu;ukusetyenziswa kwamandla aphantsi okuvelisa (ukwenza ubushushu begumbi, kunye nombhobho wensimbi ongenamthungo wokufudumeza okanye ukubumba umzobo obandayo);iindleko zokuvelisa ziphantsi, kuba ithubhu yentsimbi engenamthungo imalunga ne-2\/3;imveliso eqhubekayo, imveliso isivuno esiphezulu kunye eliphezulu.Longitudinal welded umbhobho ishishini e-China waqala 50′s, waqala emva kwexesha, inkqubo yemveliso kunye nobuchwepheshe kunye nelizwe eliphuhlileyo kuthelekiswa, wabeka umahluko omkhulu kakhulu.Uninzi lokusilela kwezixhobo zetekhnoloji yeshishini, ukunqongophala kweendlela eziyimfuneko zokubhaqa, kodwa kunye nomgangatho ophantsi webhanti elifutshane, elimxinwa njengezinto ezikrwada, kubangele iimveliso zemibhobho edityanisiweyo kunye ne-aperture encinci, umthamo ophantsi wokuthwala, ubume bemveliso abunangqiqo, i-welded. imveliso yombhobho kwi-80% ingasetyenziswa kuphela njengoxinzelelo oluphantsi lwe-fluid ehambisa umbhobho wamanzi wamalahle, zonke iintlobo zombhobho okhethekileyo umlinganiselo ophantsi.Olu hlobo lwezixhobo zokuwelda eliphantsi kunye nenqanaba lobuchwephesha, ukwenza i
