Akukho vavanyo lokusingqongileyoinkqubo yenkxaso yekhebulaindlela olusebenza ngayo ulwandle. Kwiqonga eliselunxwemeni, i-FPSO, okanye isityalo senkqubo yonxweme, umoya uzele yityuwa, ufumile, kwaye uhlala ushushu; izakhiwo ziyangcangcazela kwaye ziyashukuma; kwaye iziphumo zenkxaso ebolileyo engaphumeleliyo kwisekethe ephilayo zilinganiswa ngokulahleka kwemveliso kunye nomngcipheko wokhuseleko, kungekhona iindleko zokulungisa. I-Shanghai Qinkai Industrial Co., Ltd., umenzi we-NEMA-standard cable tray kunye neenkqubo ze-cable ladder, ithi iiprojekthi zaselwandle kunye ne-offshore zezona candelo ziqhutywa kakhulu ziinkcukacha: abathengi apho abaceli "i-cable tray" - bacela i-grade yezinto ezibonakalayo, inkqubo yokugquma, iklasi yokugqwala, kunye namaxwebhu okuqinisekisa zonke ezintathu.
“Olwandle, itreyi yekhebula idla ngokuba yimpahla yombane. Olwandle, yinxalenye ebalulekileyo yokhuseleko lwesicwangciso sokugqwala kwempahla,” utshilo inkampani kwingxelo. “Ulwandle aluxoleli indlela emfutshane. Abathengi bethu baselwandle bachaza iinkqubo zentsimbi ezifakwe i-hot-dip okanye i-stainless steel kunye nedatha yomthwalo epapashiweyo, kwaye bahlola ingxelo yokugquma ngaphambi kokuba bahlole ukuthunyelwa.”
Yintoni eyenza umoya wolwandle wahluke
Ingqiqo yobunjineli iqala ngokusingqongileyo. Iimozulu zaselwandle zihlulwe phakathi kwezona zirhabaxa kakhulu kwisikali se-ISO 12944 — udidi lwe-C5-M kwiindawo ezinxwemeni naselunxwemeni ezinetyuwa eninzi, i-CX igcinelwe ukuvezwa kakhulu elunxwemeni. Iindlela ezintathu zibangela umonakalo:
Ukugcinwa kwetyuwa. Amasuntswana etyuwa ahamba emoyeni ahlala kwintsimbi, kwaye xa kukho ukufuma enza i-electrolyte enamandla ehlasela i-zinc kunye nentsimbi ngokufanayo.
Ukumanzisa ngesantya esiphezulu. Izakhiwo zaselunxwemeni zihamba ngesantya esomileyo nesimanzi rhoqo - ukutshiza, imvula, ukufuma, kunye nenkungu yetyuwa - kwaye umjikelo ngamnye ukhawulezisa ukugqwala kwiziphene zokugquma kunye nemiphetho enqunqiweyo.
Uxinzelelo lwekloridi. Iikloridi zihlasela ii-galvanized coatings kunye ne-carbon steel ngokukhawuleza kakhulu kunokuba zisenza izinto ezingcolisayo ngaphakathi, yiyo loo nto ubukhulu be-coating kunye nokukhethwa kwezinto, kungekhona iishedyuli zokulungisa ipeyinti, zigqiba ubomi benkqubo.
Isiphumo esisebenzayo kukuba iinkqubo zetreyi ezifakwe i-electro-galvanized okanye ezipeyintiweyo eziqhelekileyo kwiindawo ezomileyo zangaphakathi azinandawo kwiinkcukacha zaselwandle. Iiprojekthi zilinganisa intsimbi efakwe i-hot-dip galvanized steel ngokwe-EN ISO 1461 okanye i-ASTM A123, okanye kwintsimbi engatyiwayo — edla ngokuba yi-Type 316 — kwiindawo apho ukufikelela kulondolozo lwexesha elide kunqongophele khona.
Amaqonga azinzileyo kunye nee-topside ze-FPSO
Kwiiplatifomu ezizinzileyo zaselunxwemeni kunye nezixhobo zokuvelisa ezidadayo, inkqubo yokuxhasa iintambo yinkqubo yemithambo-luvo yempahla.Iintambo zombaneizixhobo zenkqubo yokutya, ucinezelo, kunye noololiwe bokumpompa; izixhobo kunye neentambo zolawulo zithwala imiqondiso yolawulo lwenkqubo, iinkqubo zokhuseleko, kunye nokuvalwa kongxamiseko. Zombini zihamba kwiindlela ezixineneyo, ezinamanqanaba amaninzi ngokusebenzisa iimodyuli ezisemacaleni aphezulu apho indawo yabelwe yi-millimeter.
Iimfuno ezintathu zilawula iinkcukacha ezikwicala eliphezulu. Okokuqala, umoya: iindawo zenkqubo zivelisa ubushushu, kwaye ulwakhiwo olunomoya wetreyi kunye neenkqubo zeleli ezisemgangathweni luvumela iintambo ezinikwe amandla ukuba zikhuphe ubushushu ngelixa zigcina zonke iintambo zibonakala kwaye zilandeleka ukuze zihlolwe. Okwesibini, ukuthembeka koomatshini: inkqubo kufuneka ibambe umthwalo wayo olinganiselweyo phantsi kokuhamba kweqonga, ukungcangcazela okuvela kwizixhobo ezijikelezayo, kunye nokuphambuka kwesakhiwo seqonga ngokwalo - yiyo loo nto iitafile zomthwalo ezipapashiweyo ngobubanzi, iphimbo lerung, kunye nesithuba senkxaso ziyimfuneko ethambileyo kunokuba kube lula kwikhathalogu. Okwesithathu, izinto: inkxaso yekhebula elikwicala eliphezulu kwindawo yokutshiza kunye neendawo zenkqubo ichazwe kakhulu kwi-Type 316 stainless steel okanye i-hot-dip galvanized steel, kuxhomekeke kwifilosofi yomqhubi yokugqwala, kunye ne-stainless steel apho ukufikelela kulondolozo kunzima okanye apho iindonga ezilinganiswe ngomlilo kunye nokuqhushumba kufuneka zingene ngokucocekileyo.
Iinqanawa kunye neenqanawa zokuxhasa ulwandle
Iinqanawa kunye neenqanawa zokuxhasa zaselwandle zongeza indlela eyahlukileyo: isiqinisekiso. Iinkqubo zokuxhasa iintambo ezifakwe kwiinqanawa ezihleliweyo zihlala ziphantsi kwemithetho yombutho wokwahlulahlula - i-DNV, i-ABS, i-Lloyd's Register phakathi kwazo - kwaye ukufakwa kufuneka kulandelelwe kwizixhobo kunye nemizobo evunyiweyo. Iindawo zemikhumbi zikwadibanisa ukungcangcazela okuqhubekayo, ukuhanjiswa okulinganiselweyo kumagumbi eenjini kunye neendawo zobugcisa, kunye nesidingo seenkqubo ezinokutshintshwa ngexesha leedoki ezomileyo ngaphandle kokwenziwa okukhethekileyo ebhodini.
Ngenxa yezi zizathu, umsebenzi weenqanawa uthanda itreyi eboshiweyo, ebotshiweyo kwangaphambili kwayeiinkqubo zelelienoluhlu olupheleleyo lwezixhobo zokufakela — ii-bends, tees, crosses, reducers, kunye neeyunithi zokulahla — ngoko ke indlela inokulungiswa ngokutsha ngezixhobo zehardware kunye nezixhobo zesandla ezisemgangathweni. Ubukhulu obuncinci kunye nobude becandelo obuqikelelweyo bubalulekile njengokusebenza kokugqwala, kuba indawo ngaphakathi kweendawo zobugcisa zenqanawa incinci kakhulu kunaso nasiphi na isityalo esiselunxwemeni.
Umoya ovuthuzayo ongaphandle kolwandle
Iifama zomoya ezingaselunxwemeni zandisa imithetho efanayo yokugqwala kwicandelo elikhula ngokukhawuleza. Iinqaba, iziqwenga zotshintsho, kunye nezikhululo ezingaphantsi kolwandle zihlala kwindawo efanayo ye-C5-M njengezixhobo zeoyile negesi, kodwa zineemfuno ezimbini ezongezelelweyo: iiasethi azinamntu, ngoko ke iifestile zokulungisa zimfutshane kwaye zibiza kakhulu, kwaye iintambo - iintambo ze-medium-voltage array, iisekethe zokuthumela umbane ngaphandle, kunye neenkqubo zolawulo kunye ne-SCADA - kufuneka zihlale zithembekile kubomi boyilo lwe-turbine ngaphandle kokungenelela rhoqo.
Isiphumo senkcazo kukukhethwa okukhulu kwenkxaso yentambo yentsimbi engagqwaliyo kwiindawo ze-nacelle kunye neendawo zotshintsho, kunye neenkqubo ze-hot-dip galvanized ezamkelweyo kwiindawo ezingatyhilekanga kangako, kunye nolawulo lwentambo olugcina ii-conductors zilungelelaniswe ngaphakathi kwe-tower enzima yokungcangcazela. Njengoko iifama zomoya zisiya kude nolwandle kwaye zisiya kwiifomathi ezinkulu, abaqhubi basebenzisa iinkcukacha zenkxaso yentambo ye-oyile kunye negesi kwicandelo elalibolekwe ngaphambili kwi-onshore practice - ababoneleli be-shift bajonge ngokusondeleyo.
Iindawo zokuthutha iinqanawa, amazibuko, kunye nezityalo zaselunxwemeni
Ayizizo zonke iinqanawa zobunjineli bolwandle ezidadayo. Iinqanawa zakha kwaye zilungisa iinqanawa phantsi kweemeko zaselunxwemeni ezivulekileyo; amazibuko asebenzisa izixhobo zokuphakamisa izinto ezinzima, iinkqubo zokuphatha iikhonteyina, kunye nokufakelwa kwamandla olwandle emoyeni ogcwele ityuwa; izityalo zokukhupha ityuwa kunye nezibonelelo zenkqubo yonxweme zisebenzisa iinkqubo zombane eziqhubekayo ezimitha ukusuka elwandle. Ezi zixhobo zonxweme ezizinzileyo zabelana ngolawulo lokugqwala kolwandle ngaphandle kwebhajethi yolwandle yezinto zangaphandle, nto leyo eyenza zibe yeyona marike inkulu yeenkqubo ze-hot-dip galvanized.
Kwiikhreyini ze-gantry zasemabaleni eenqanawa, iikhreyini ze-quay, kunye neeprojekthi zokufakelwa kombane kwizibuko,Itreyi yekhebula le-HDGkunye neenkqubo zeleli ngokwe-EN ISO 1461 zibonelela ngobomi benkonzo obufunekayo ngexabiso eliphantsi kunexabiso le-stainless — ukuba nje i-coating ityebile ngokwaneleyo, ii-fittings zine-coating specification efanayo namacandelo athe tye, kwaye iziphelo ezisikiweyo ziphathwa nge-zinc-rich repair coating. Ubonelelo lomthombo omnye lubalulekile apha: xa ii-couplers, ii-fittings, kunye nee-supports zivela kumgca ofanayo wemveliso njengetreyi, umgangatho we-coating uyafana kulo lonke uhambo, kwaye iindawo ezibuthathaka ezibonakala kwiindawo ezidityanisiweyo zabathengisi ziyanyamalala.
Ukukhetha izinto ezifanelekileyo kunye nokugqiba
Kwiinjineli ezichaza inkxaso yekhebula kuyo nayiphi na imeko-bume yolwandle, isikhokelo sikaQinkai sincipha siye kwizigqibo ezine:
Tshatisa umgangatho nendawo yokuvezwa. Gcina intsimbi engagqwaliyo yohlobo lwe-316 kwiindawo zokutshiza, iindawo zokucubungula, kunye neempahla ezingenamntu apho ukugcinwa kunzima khona; sebenzisa intsimbi eshushu ediphiweyo ngokwe-EN ISO 1461 okanye i-ASTM A123 kwiindawo eziselunxwemeni nasemoyeni; gcina iinkqubo ezifakwe i-electro-galvanized kunye nepeyintiweyo zingabikho ngokupheleleyo kwiinkcukacha zaselwandle.
Cinga ngomhlwa we-galvanic. Xa intsimbi engagqwaliyo kunye ne-aluminium, okanye intsimbi engagqwaliyo kunye ne-carbon, zidibene kwindawo enetyuwa, umhlwa we-bimetallic unokutshabalalisa isinyithi esingesihle kangako. Cacisa izinto ezihambelanayo okanye ulwahlulo olugqunywe nge-insulation kuyo yonke indawo, kuquka izibophelelo kunye nezibiyeli.
Khusela yonke into esikiweyo kunye nokukrwela. Iziphelo ezisikiweyo ebaleni kunye nemingxunya ebholiweyo kulapho kuqala khona ukubola kolwandle. Ukhuseleko lwe-HDG lwe-cathodic lukhusela intsimbi kwezi ndawo, kwaye uphahla lokulungisa olunezinki eninzi kufuneka lusetyenziswe naphi na apho uphahla lonakele khona kwindawo.
Funa amaxwebhu. Iitafile zomthwalo, iingxelo zobukhulu be-coating, kunye neesatifikethi zezinto ezibonakalayo zizinto ezahlula phakathi kwenkqubo echazweyo kunye ne-gamble. Kwiiprojekthi zaselwandle, ingxelo ye-coating ihlolwa ngononophelo njengetreyi yekhebula ngokwayo.
Imigangatho elawula inkxaso yekhebula laselwandle
Isakhelo semigangatho yeenkcukacha zetreyi yekhebula yaselwandle neyaselwandle iyahambelana kuzo zonke iindawo: I-IEC 61537 igubungela iimfuno zovavanyo kunye nokumakishwa kwetreyi yekhebula kunye neenkqubo zeleli; I-EN ISO 1461 kunye ne-ASTM A123 zilawula iingubo ze-hot-dip galvanized coatings; I-ISO 12944 ichaza iindidi zokugqwala eziqhuba ukukhethwa kwezinto; I-NEMA VE 1 kunye ne-VE 2 zixhasa umkhuba waseMntla Melika; kwaye imithetho yoluntu lokwahlulahlula yongeza umaleko ongezelelweyo weenqanawa kunye nezibonelelo ezidadayo. Iiprojekthi zifuna ngakumbi ukuba zonke ezi zinto zingasentla zibhalwe phantsi ngokuthunyelwa ngakunye - ibha ehluza ababoneleli abangakwaziyo ukuvelisa idatha yomthwalo exhaswa luvavanyo.
Uvavanyo lokuthenga
Ipateni kuzo zonke iindawo zaselwandle iyafana: iinkcukacha zigqitywa ziinjineli zokugqwala kunye nabanini beeasethi ngaphambi kokuba kuqeshwe umenzi wombane, kwaye ababoneleli abaphumelelayo ngabo banokubhala phantsi umgangatho wezinto, ukusebenza kwengubo, kunye nokulinganiswa komthwalo ngaphandle kokuthandabuza. “Itreyi yekhebula laselwandle ithengwa kube kanye ize ihlolwe amashumi eminyaka,” utshilo inkampani. “Sakha eyethu ukuze lonke uhlolo lufumane into efanayo: inkqubo ebhaliweyo, eyenza kanye loo nto ichazwe yinkcazo.”
