Kwinkqubela phambili ebalulekileyo yecandelo lokwenziwa kwentsimbi, inkampani ehamba phambili yentsimbi iye yafumana ikhontrakthi enkulu yokwenziwa kunye nonikezelo lwemibhobho yentsimbi ene-spiral-welded, eyaziwa ngokuba yi-SSAW (Spiral Submerged Arc Welded) imibhobho, kwiprojekthi ephezulu kunye ISaudi Aramco. Esi sivumelwano asigxininisi nje kuphela imfuno ekhulayo yeemveliso zentsimbi ezikumgangatho ophezulu kwicandelo lezamandla kodwa ikwaqaqambisa ukuqhubela phambili kobuchwepheshe ekwenzeni imibhobho eyimfuneko ekuhlangabezaneni nemigangatho engqongqo yenye yeenkampani ze-oyile ezinkulu zehlabathi.
Ukuqonda i-Spiral-Welded Steel Pipes
Imibhobho yentsimbi ene-Spiral-welding luhlobo lombhobho wentsimbi oveliswa ngokuwelda ngokujikelezayo umcu wentsimbi osicaba ube yimilo ye-tubular. Le ndlela yokuvelisa inika iingenelo ezininzi kubuchule bemveli bomthungo wokuwelda. Inkqubo ye-spiral welding ivumela ukudalwa kwemibhobho emikhulu yedayamitha, eyimfuneko kwizicelo ezahlukeneyo, ngakumbi kwishishini leoli negesi.
Imibhobho ye-SSAW ibonakaliswe ngamandla abo aphezulu kunye nokuqina, okwenza kube lula ukuthutha ulwelo kunye neegesi phantsi koxinzelelo oluphezulu. Zihlala zisetyenziselwa izicelo ezifana nokunikezelwa kwamanzi, iinkqubo zogutyulo, kwaye, okona kubaluleke kakhulu, kwicandelo leoli kunye negesi yokuthutha i-oyile ekrwada kunye negesi yendalo kumgama omde.
Iprojekthi yeAramco
ISaudi Aramco, inkampani yeoyile ephantsi kukarhulumente yaseSaudi Arabia, yaziwa ngoovimba bayo abakhulu kunye neziseko ezingundoqo. Inkampani isoloko ityala imali kwiiprojekthi eziphucula amandla ayo okuvelisa kunye nokuphucula ukusebenza kakuhle kwemisebenzi yayo. Iprojekthi yamva nje, apho imibhobho yentsimbi edityanisiweyo iza kubonelelwa, kulindeleke ukuba idlale indima ebalulekileyo ekwandiseni uthungelwano lwemibhobho ye-Aramco.
Imfuno yemibhobho ye-SSAW kule projekthi iqhutywa yimfuneko yothutho oluthembekileyo nolusebenzayo lwee-hydrocarbons. Iimpawu ezikhethekileyo zemibhobho ye-spiral-welded, kubandakanywa ukukwazi ukumelana noxinzelelo oluphezulu kunye neendawo ezinobungozi, zibenza ukuba babe lukhetho olufanelekileyo kwizicelo ezinjalo. Ngaphezu koko, ukuguquguquka kwimveliso kuvumela ukulungelelanisa ngokumalunga nobubanzi kunye nobukhulu bodonga, ukulungiselela iimfuno ezithile zeprojekthi.
Iimpembelelo kuQoqosho
Esi sivumelwano asikona nje ukuphumelela kumenzi wensimbi kodwa kuneempembelelo ezibanzi zezoqoqosho. Ikhontrakthi kulindeleke ukuba idale imisebenzi kwicandelo lezemveliso, igalelo kuqoqosho lwasekhaya. Ukongezelela, ukuphunyezwa ngempumelelo kwale projekthi kunokukhokelela kwiikontraka ezongezelelweyo kunye ne-Aramco kunye nezinye iinkampani kwicandelo lamandla, ngaloo ndlela kukhulise imboni yensimbi ngokubanzi.
Ishishini lentsimbi liye lajamelana nemingeni kwiminyaka yamuva nje, kuquka ukuguquguquka kwamaxabiso kunye nokhuphiswano oluvela kwezinye izinto. Nangona kunjalo, imfuno ekhulayo yeemveliso zetsimbi ezikumgangatho ophezulu, ngokukodwa kwicandelo lamandla, libonisa ithuba elibalulekileyo lokukhula. Iprojekthi ye-Aramco ibubungqina bokuqina kweshishini lensimbi kunye nokukwazi ukulungelelanisa nokutshintsha kweemeko zemarike.
Ukuphuculwa kwezobuChwephesha kwiMveliso yeMibhobho
Ukuveliswa kwemibhobho yentsimbi ene-spiral-welded ibone inkqubela phambili yezobuchwepheshe kwiminyaka yakutshanje. Ubuchule bokuvelisa banamhlanje buphucule ukusebenza kakuhle kunye nomgangatho wemibhobho ye-SSAW, evumela amaxesha okuvelisa ngokukhawuleza kunye nokunciphisa iindleko. Ubuchwephesha be-welding obuphezulu, obufana ne-arc welding ephantsi kwamanzi, iqinisekisa amajoyina anamandla kwaye athembekileyo, abaluleke kakhulu ekuthembekeni kwemibhobho.
Ngaphezu koko, izinto ezintsha kwisayensi yezinto eziphathekayo zikhokelele ekuphuhlisweni kwamanqanaba aphezulu entsimbi aphucula ukusebenza kwemibhobho ye-spiral-welded. Olu phuculo aluphuculi nje kuphela ukuqina kwemibhobho kodwa lukwanegalelo kukhuseleko lulonke lwemisebenzi yemibhobho.
Ukuqwalaselwa kokusingqongileyo
Njengoko ihlabathi lisiya kwizenzo ezizinzileyo, ishishini lentsimbi nalo lenza amanyathelo okunciphisa impembelelo yalo yokusingqongileyo. Ukuveliswa kwemibhobho yentsimbi ene-spiral-welded ingaphuculwa ukunciphisa inkcitho kunye nokusetyenziswa kwamandla. Ukongezelela, ukusetyenziswa kwezixhobo eziphezulu zamandla kuvumela iindonga ezincinci, ezinciphisa inani lentsimbi efunekayo kwimveliso, iyancipha ngakumbi indawo yokusingqongileyo.
Ngaphaya koko, ukuthuthwa kwe-oyile nerhasi ngemibhobho ngokuqhelekileyo kuthathwa njengokulungeleka kokusingqongileyo xa kuthelekiswa nezinye iindlela, ezifana neelori okanye uthutho lukaloliwe. Ngotyalo-mali kwiziseko ezisebenzayo zemibhobho, iinkampani ezifana ne-Aramco aziphuculi nje ukusebenza kwazo ngokufanelekileyo kodwa zinegalelo kwikamva lamandla elizinzileyo.
Ukuqukumbela
Isivumelwano sakutsha nje sokwenziwa kunye nokunikezelwa kwemibhobho yentsimbi ene-spiral-welded yeprojekthi ye-Aramco siphawula isiganeko esibalulekileyo kushishino lwentsimbi. Igxininisa imfuno ekhulayo yeemveliso zetsimbi ezikumgangatho ophezulu kwicandelo lamandla kwaye igxininisa ukubaluleka kokuqhubela phambili kwezobuchwepheshe kwimveliso yombhobho. Njengoko ihlabathi liqhubeka lithembele kwioli kunye negesi, indima yeenkampani ezifana ne-Aramco kunye nabanikezeli bazo baya kubaluleka ekuqinisekiseni ukuthuthwa okukhuselekileyo nokufanelekileyo kwezi zixhobo ezibalulekileyo.
Esi sibhambathiso asithembisi nje kuphela iinzuzo zoqoqosho kodwa sikwabonakalisa ukuzibophelela kweshishini ekusunguleni nasekuzinziseni. Njengoko ishishini lentsimbi liqhuba imingeni yehlabathi lanamhlanje, intsebenziswano efana nale iya kubaluleka ekuqhubeni ukukhula nokuqinisekisa ikamva elizinzileyo lothutho lwamandla. Ukuphunyezwa ngempumelelo kweprojekthi ye-Aramco kunokuvula indlela yokuqhubela phambili intsebenziswano, ukuqinisa ukubaluleka kweemveliso zentsimbi ezikumgangatho ophezulu kumhlaba wamandla ehlabathi.
