Enkola z’okuteeka payipu za cWC
Okusinziira ku DNVGL-RP-F103, okuteeka obulungi anodes kikulu nnyo okukakasa okusaasaana kwa kasasiro okwa kimu n’okukola obulungi okumala ebbanga eddene-. Octal Pipe egaba eby’okugonjoola ebizibu ebingi eby’okussaako okusinziira ku dizayini ya payipu n’obutonde:
1. Welded attachment (pads / obukomo) .
Okufuga ekifo:Anodes ziteekebwa okwewala ebiyungo by’omu nnimiro, ebiwanirizi, n’ebitundu ebikontana n’ebiwunyiriza, ebiwujjo oba okukwatagana kw’ekisika.
Weld + coating okuddaabiriza empisa:Ebitundu bya weld bitegeezebwa, olwo okusiiga ne kuddaabirizibwa ne kusibwa okuziyiza "okwokya okutono, akasenge akakulu akakulukuta."
Obukuumi bwa waya:Routing ekuumibwa era ekuumibwa kale tesiba nga ekwata n’okukka.
2. Okuteeka clamp/strap (ekintu eky’okussaako anode) .
Kit scope okutegeera:Ekintu ekya bulijjo eky’okuteeka anode kirimu omubiri gwa clamp/saddle, straps/fasteners, insulation pads, continuity cable, n’ebintu ebisiba-kale omukozi takola improvising mu kifo.
Omutindo gw’okutuukirira:Fit surfaces zifugibwa okwewala high-resistance contact eyita mu kulaba naye nga eremererwa mu masannyalaze oluvannyuma.
Anti-okusumulula n'okukwata entambula:Strapping kirambikiddwa kale ewona okuvuga loole, okusitula, n’okuteeka tension nga tekyusiddwa.
3. Embedded mu CWC (ku CP ekuumibwa ku payipu esiigiddwa obuzito bwa seminti) .
Teeka geometry:Recess/cover efugibwa kale anode ekuumibwa okuva ku kukubwa n’okusika nga ekyakola amasannyalaze.
Ebifuluma mu waya n’okusiba:Ebifo we bafulumira waya bikuumibwa era ne bisibibwa ne bitafuuka bifo bya snag oba amakubo g’amazzi.
Enkyukakyuka eziggwaako:Zooni ya CWC/anode ekwatagana n’okusala kwa welding kale okusiiga kw’ekiyungo ky’omu nnimiro kuyinza okukolebwa mu ngeri enyonjo (bwe kirambikiddwa).
Okuteeka wansi w’amazzi:
Ku payipu z’ennyanja ennene, anode ziteekebwa ku nnyanja nga zikolebwa abavubi oba mmotoka eziddukanyizibwa okuva ewala (ROVs).
Clamps ez’enjawulo n’enkola za welding zikozesebwa okukakasa nti ziteekebwa mu ngeri etali ya bulabe era entuufu.
DNVGL-RP-F103 eraga enkola z'ebanga n'okugattako okukakasa nti wadde CP ebikka.
Okuteeka omuggo gwa anode ogulina amaanyi (ICCP):
Emiggo gya anode (MMO, titanium-based) giteekebwa ku kkubo lya payipu.
Eyungiddwa ku transformer-rectifiers ku lukalu oba ku pulatifomu ez'okungulu.
Ewa current etereezebwa, esaanira payipu z’amazzi amawanvu nga zirina obwetaavu bwa CP obw’amaanyi.
enkola y’okuteeka anode
Kino kikozese nga...enkola y’okuteeka anodebaseline era oginyweze mu ITP yo we kyetaagisa:
Okukakasa omulimu nga tekunnabaawo-:Kakasa enkola y'okusiiga, CWC okuzimba-up (bwe kiba kisoboka), enteekateeka y'ebanga lya anode, ne "tewali-genda" zones okumpi n'ennimiro joints/supports.
- Okussaako obubonero & okutuuka-up:Laga ebifo buli kifaananyi; okukakasa clearance okuteeka ebyuma n’ebifo ebikwata.
- Enkwatagana:Teeka mu nkola ya welded oba clamp/strap; okukuuma cable routing n’okukendeeza ku buzibu.
- Okukebera okugenda mu maaso:Kola okukebera okugenda mu maaso/obuziyiza bw’amasannyalaze era owandiike ebivuddemubwe kirambikiddwa mu PO/ITP.
- Okusiba & okuddaabiriza:Ddabiriza/patch local coating damage, seal cable exits, era ddamu-kebere ebifo ebiddaabiriziddwabwe kirambikiddwa.
- Nga-ebiwandiiko bwe byazimbibwa:Okulongoosa anode IDs/ebifo n’ebiwandiiko by’okugezesa okusobola okutandika okukola n’okulondoola CP mu biseera eby’omu maaso.
Ebirungi ebiri mu by’ekikugu
Octal Pipe's anode installation solutions zituwa okufuga okunywevu okukulukuta n'emigaso egy'ekikugu egy'enjawulo:
