Selelekela:
Li-flange tsa metsing, tse tsejoang hape e le li-flange tsa letšoao la likepe, ke karolo ea bohlokoa ea lisebelisoa tsa likepe le liphaephe. Li bapala karolo ea bohlokoa ho netefatseng botšepehi le ts'ebetso ea litsamaiso tsa likepe. Bukeng ena, re tla hlahloba lihlopha le litšobotsi tsa li-flange tsa leoatle, re hlakise mefuta le lits'ebetso tsa tsona tse fapaneng. Hore na u ameha indastering ea likepe kapa u mpa u labalabela ho tseba ka boenjiniere ba likepe, sengoloa sena se ikemiselitse ho u fa kutloisiso e felletseng ea li-flange tsa leoatle.
1. Sekoahelo sa ho Welding sa Marine Flat:
Lesela la ho welding le bataletseng la lewatle ke mofuta o sebediswang haholo wa lesela la lewatle. Le kenyeletsa ho kenya phaephe ka hara lesale le ka hare la lesela le ho le welding. Ho na le mefuta e mmedi e meholo sehlopheng sena: lesela la ho welding le bataletseng la molaleng le lesela la ho welding le nang le letheka la poleiti. Le hoja lesela la ho welding le bataletseng le fana ka tlhahiso e bonolo le ditjeo tse tlase tsa tlhahiso, ha le a lokela ditshebediso tsa mocheso o phahameng le kgatello e phahameng. Tshebediso ya lona ya mantlha ke bakeng sa diphaephe tse tlwaelehileng tsa mocheso tse nang le kgatello e ka tlase ho 2.5 MPa. Ke lesela le sebediswang haholo dikepeng ka lebaka la ho ba le ditjeo tse tlase.
2. Sekotjana sa ho Welding sa Marine Butt:
E tsejoang hape e le flange e phahameng ea molala, flange ea ho welding ea marine butt e khetholloa ka molala oa eona o nang le phetoho ea phaephe e chitja 'me e hoketsoe ka butt ho phaephe. Mofuta ona oa flange o tiile haholo, o hanela ho fetoha ha sebopeho, 'me o fana ka bokhoni bo botle ba ho koala. E sebelisoa haholo maemong a nang le khatello le mocheso o phahameng, ka khatello e tloaelehileng e fetang PN16MPa. Li-flange tsa ho welding ea marine butt li loketse haholo litsamaiso tsa liphaephe tsa moea tse hatelletsoeng le litsamaiso tsa liphaephe tsa carbon dioxide.
3. Sekoahelo se Lokolohileng sa Leoatleng:
Lesela le lokolohileng la metsing, le tsejoang hape e le lesela le lokolohileng la letsoho, le sebelisa motsoako oa thepa e fapaneng bakeng sa ho boloka litšenyehelo. Maemong ao thepa ea phaephe e turang, lesela le lokolohileng le sebelisa sehokelo sa kahare se entsoeng ka thepa e tšoanang le phaephe, hammoho le lesela le entsoeng ka thepa e fapaneng. Lesela le lokolohileng la letsoho le beoa pheletsong ea phaephe, e leng se lumellang motsamao. Hangata le sebelisoa liphaepheng tsa alloy tsa koporo-nickel le manonyeletsong a katoloso.
4. Sefate sa ho betla sa metsing sa haeteroliki:
Flange ea hydraulic ea leoatleng e etselitsoe ka ho khetheha litsamaiso tsa liphaephe tsa hydraulic tsa leoatleng tse nang le khatello e phahameng. Ho mamella khatello e phahameng, ho sebelisoa flange e khethehileng ea mofuta oa socket-high-pressure. Ho latela bophara ba phaephe, botenya ba flange hangata bo tloha ho 30mm ho isa ho 45mm. Flange ena hangata e hlophisoa ho sebelisoa mokhoa oa khokahano ea flange e kobehileng le e kobehileng, ka lesale la O le sebelisoang e le thepa ea ho koala. Li-flange tsa hydraulic tsa leoatleng li netefatsa ts'ebetso e tšepahalang le e sebetsang hantle litsamaisong tsa hydraulic tsa leoatleng tse hlokang thuso.
Qetello:
Li-flange tsa leoatleng, tse tsejoang hape e le li-flange tsa letšoao la likepe, ke karolo ea bohlokoa ea lisebelisoa tsa likepe le liphaephe. Ka lihlopha le litšobotsi tsa tsona tse ikhethang, li-flange tsa leoatleng li fana ka litharollo tse feto-fetohang le tse tšepahalang bakeng sa lits'ebetso tse fapaneng tsa likepe. Ho tloha ho li-flange tse bataletseng tsa ho welding ho ea ho li-flange tsa ho welding tsa butt, li-flange tse lokolohileng le li-flange tsa hydraulic, mofuta o mong le o mong o na le litšobotsi tsa oona tse ikhethang tse etsang hore li lokele maemo a itseng. Ho utloisisa karohano le ts'ebeliso ea li-flange tsa leoatleng ho bohlokoa bakeng sa ho netefatsa katleho le polokeho ea litsamaiso tsa likepe.
Ka ho fana ka kakaretso ena e felletseng, re tšepa ho ntlafatsa tsebo ea hau ea li-flange tsa leoatleng le ho kenya letsoho kutloisisong ea hau ea indasteri ea likepe. Ebang u setsebi sa likepe kapa motho ea chesehelang, ho ba le thahasello ho li-flange tsa leoatleng ntle ho pelaelo ho tla tebisa kutloisiso ea hau ea boenjiniere bo etsang hore likepe tsa sejoale-joale le li-platform tsa leoatleng li khonehe.
