CWC Anode yo gushiraho ibisobanuro

Kwinjiza Anodeni umurimo wo guhuza anode yigitambo kumuyoboro - mugusudira, gufunga / guhambira, cyangwa kubishyira mubice bya CWC - bityo anode ikabora mbere kandi umuyoboro wibyuma ugakomeza kurindwa murwego rwa sisitemu yo kurinda catodiki (CP). Kuri CWC itwikiriye umuyoboro, ikubiyemo no kugenzuraumwanya wa anode, uburyo bwo gukosora, hamwe no kurinda insingaanode rero ikomeza gukora amashanyarazi itarangiritse mugihe cyo kuyikora, kuryama, cyangwa gusudira kumurima.
Sisitemu ebyiri nyamukuru zikoreshwa:

Anode y'ibitambo (Zn, Al, Mg):Byoroshye, kubungabunga - kubuntu, nibyiza kumazi magufi nubutaka.
Byatangajwe na Anode Yubu (MMO, Si - icyuma):Bikoreshejwe nogukosora, birashobora guhindurwa, bikwiranye namazi maremare kandi maremare -.

Umuyoboro wa Octal ushushanya kandi ugashyiraho sisitemu ya anode cyane kuri DNVGL - RP - F103, ISO 15589-2, na NACE, itanga uburyo bwiza bwo gutandukanya, guhuza, nuburyo bwo kwishyiriraho (gusudira, gufunga, cyangwa CWC yashyizwemo).

Uburyo bwo Gushyira Umuyoboro

Anode Installation octal

Dukurikije DNVGL - RP - F103, gushyiraho anode ni ngombwa kugirango habeho gukwirakwiza icyarimwe hamwe nigihe kirekire -. Umuyoboro wa Octal utanga ibisubizo byinshi byubushakashatsi bitewe nigishushanyo mbonera n’ibidukikije:

1. Umugereka wo gusudira (padi / bracelets)

Igenzura ryaho:Anode ihagaze kugirango yirinde guhuza umurima, gushyigikira, hamwe nuduce duhura na stingers, umuzingo, cyangwa guhuza amakimbirane.

Gusana gusudira + gusana:Ahantu ho gusudira harasobanuwe, hanyuma igipfundikizo kirakosorwa kandi kigafungwa kugirango birinde "gutwika bito, ingirabuzimafatizo nini."

Kurinda insinga:Inzira ifite umutekano kandi irinzwe kuburyo idashobora kunyerera mugihe cyo gukora no kumanura.

2. Gushiraho Clamp / strap mounting (ibikoresho byo gushiraho anode)

Urutonde rwibikoresho bisobanutse:Igikoresho gisanzwe cya anode kirimo clamp / indogobe yumubiri, imishumi / ibifunga, udukariso, insinga zikomeza, hamwe nibikoresho bifunga - kugirango rwiyemezamirimo adatezimbere kurubuga.

Ubwiza bw'itumanaho:Ubuso bwiza bugenzurwa kugirango wirinde - guhuza imbaraga zinyura mu buryo bugaragara ariko bikananirana amashanyarazi nyuma.

Kurwanya - kurekura no gutwara ibintu:Guhambira birasobanutse kuburyo irokoka ikamyo, guterura, no gushira impagarara idahindutse.

3. Yashyizwe muri CWC (kuri CP ikingiwe kumuringoti ufite uburemere bwa beto)

Ikimenyetso cya geometrie:Ikiruhuko / igifuniko kiragenzurwa kuburyo anode irinzwe ingaruka no gukurura mugihe bikiri amashanyarazi.

Umugozi usohoka no gufunga:Ahantu hasohokera hashobora gukingirwa no gufungwa kugirango bidahinduka inzira cyangwa inzira y'amazi.

Inzibacyuho irangira:Agace ka CWC / anode kahujwe no gusudira kugabanwa kugirango umurima uhuriweho ushobora gukorwa neza (mugihe byerekanwe).

Gushyira mu mazi:

Ku miyoboro yo mu mazi, anode zishyirwa hanze kubatwara ibinyabiziga cyangwa ibinyabiziga bikorerwa kure (ROVs).

Sisitemu yihariye hamwe na sisitemu yo gusudira bikoreshwa mukwemeza neza kandi neza.

DNVGL - RP - F103 yerekana uburyo bwo gutandukanya no kugerekaho kugirango harebwe CP.

Gukoresha Anode Inkoni (ICCP):

Inkoni ya Anode (MMO, titanium - ishingiye) ishyirwa kumuhanda.

Uhujwe na transformateur - ikosora ku nkombe cyangwa hejuru ya platifomu.

Itanga imiyoboro ihindagurika, ibereye imiyoboro y'amazi maremare hamwe na CP ikenewe cyane.

uburyo bwo kwishyiriraho anode

Koresha iyi Nkauburyo bwo kwishyiriraho anodeshingiro no kuyizirika muri ITP yawe aho bikenewe:

Mbere - kwemeza akazi:Emeza sisitemu yo gutwikira, CWC yubaka - hejuru (niba bishoboka), gahunda yumwanya wa anode, na "oya - go" zone hafi yumurima uhuza / inkunga.

Ikimenyetso & gikwiye - hejuru:Shyira ahantu ku gishushanyo; kugenzura neza kugirango ushire ibikoresho hamwe ningingo zikoreshwa.
Umugereka:Shyiramo uburyo bwo gusudira cyangwa gufunga / gukanda; inzira ya kabili itekanye kandi itoroshye.
Kugenzura ubudahwema:Kora amashanyarazi akomeje / kugenzura no kwandika ibisubizoiyo bisobanuwe muri PO / ITP.
Ikidodo & gusana:Gusana / gutema ibyangiritse byangiritse, kashe ya kabili isohoka, hanyuma re - reba ahantu hasanwemugihe cyagenwe.
Nka - yubatswe inyandiko:Kuvugurura indangamuntu ya anode / ahantu hamwe nibisobanuro byikizamini cyo gutangiza no gukurikirana CP.

Ibyiza bya tekiniki

Anode Installation octal pipe

Octal Pipe ya anode yo kwishyiriraho itanga igenzura rikomeye hamwe nibyiza byinshi bya tekiniki:

Ubuzima bwagutse bwa serivisi:

DNVGL {{}

Ikwirakwizwa ryiza rya none:

Igishushanyo mbonera gikora polarisiyasi imwe yubuso.

Irinde gukingirwa kurinda cyangwa gukingirwa birenze, byombi bishobora gutera impuzu.

Umutekano mu Bidukikije:

Sisitemu y'ibitambo ntabwo isaba imbaraga, ikuraho ingaruka ziterwa na zone yaka umuriro.

Sisitemu ya ICCP yateguwe hamwe nogukurikirana byikora hamwe nubugenzuzi bugezweho kugirango habeho gukora neza.

Kwishyira hamwe hamwe na Coatings & CWC:

Imirimo ijyanye na FBE, 3LPE, 3LPP, na CWC, itanga ruswa kandi ituje.

Iremeza gutwikira ubunyangamugayo mugihe wongeyeho CP hamwe nubucucike.

Guhuza n'imihindagurikire y'ikirere:

Igitambo cya CP - Byoroshye, hasi - kubungabunga, nibyiza kubidukikije / bidatinze.

ICCP - Birashobora guhinduka, bikwiranye n’amazi maremare kandi maremare - imiyoboro yohereza hanze.

Imikorere Yagaragaye Kumurongo:

Bikoreshwa mumiyoboro yo mumazi, risers, hamwe na J -, guhuza DNV kumurongo wumutekano.

Kwishyiriraho Anode kumuyoboro wa CWC (Clearance, Ibyangiritse, na Cable Protection)

Kuri aCWC yatwikiriye umurongo, anodekwishyirirahontabwo ari ibya CP gusa ibisohoka. Ingaruka zifatika nuko anode ninsinga bibaingingo / ingarukamugihe cyo gukurura - muri, guterura imbuga, guhuza imashini, no gukora ibikorwa - noneho umushinga wishyura gusana no kugenzura -. Iki gice cyibanze ku kwishyiriraho anode ku muyoboro mu buryo bugumaho amashanyarazi kandi yubaka binyuze muri CWC no gusudira mu murima.

Umugozi wangiritse kuva gukurura, guterura imigozi, cyangwa umuyoboro - kugeza - umuyoboro uhuza	Imiyoboro ya kabili hamwe nubutabazi bworoshye, kwiruka birinzwe, no gusohoka bifunze; irinde ibizunguruka	Umuyoboro wa kabili urambuye + uburyo bwo gufunga; urutonde rugaragara; gusana / re - logi yikizamini (niba ihari)
Uruhande rwa beto ruzunguruka hafi yumugereka nyuma yo gutwara	Igenzura hejuru yimibonano, irinde gupakira intebe za anode kumpande zoroshye; vuga ingingo zifatika / amategeko yo gutondekanya kugirango zone ya anode idafata ingaruka	Gukoresha / gupakira inoti; amafoto yo mu gikari abisabwe; ibyangiritse byo kwemerwa niba byavuzwe muri PO / ITP
Kwangirika kwangirika kuri padi / gusudira aho utangirira uturemangingo twangirika	Sobanura ubuso bwo gutegura no gutwikira intambwe zo gusana hafi yumugereka; kugenzura ahantu hasanwe (mugihe bikenewe)	Inyandiko yo gusana; ikiruhuko cyibiruhuko / re - kugenzura inyandiko (mugihe byerekanwe)
Guhagarika amashanyarazi byavumbuwe bitinze (nyuma yo kuryama cyangwa mbere yo gutangira)	Saba gukomeza / kugenzura kugenzura mubyumvikanyweho no gufata ibisubizo	Gukomeza / kurwanya ikizamini cyibizamini: uburyo + ishingiro ryemewe + ibisubizo (mugihe byerekanwe)

Umwanya wa Anode & Igishushanyo mbonera (Irinde amakimbirane ahuriweho)

Ibikorwa byinshi byo kwishyiriraho anode bibaho kuko amategeko yumwanya yanditse nka "X metero isanzwe" utabanje gutekerezaguhuza umurima, kugabanuka kwa CWC, no gushiraho ibikoresho. Amategeko akurikira afasha kugumisha imiterere yubatswe kumuyoboro wa CWC mugihe uzigama intego ya CP.

Ibibazo

Q 1 - Nigute ushobora kwirinda ibibazo byamashanyarazi mugihe anode yashizwe kumiyoboro ifatanye uburemere?

Igisubizo: Kuriuburemere bwa beto yubatswe, gahunda yo kwishyiriraho igomba gushyiramo ingingo zo gukumiraguhuza amashanyarazi hagati ya anode no gushimangira beto, kandi ibi bigomba gukemurwa muri IPS / ITP. .

Q 2 - Ni ubuhe buryo bwo gushiraho anode bukubiyemo?

Igisubizo: birakwiyeuburyo bwo kwishyiriraho anodemubisanzwe byanditswe nka IPS / ITP - urutonde rwakazi rwiteguye rukubiyemo kwakira / gutunganya / kubika anode, gushushanya birambuye (hamwe no kwihanganira), kugenzura / kugerageza gufunga, hamwe ninyandiko zanditse. Ubu buryo bwa "progaramu spec" bwiswe mu buryo bweruye mu buyobozi bwa DNV ku miyoboro yo mu mazi.

Q 3 - Ni izihe nyandiko zigomba kuzana anode (yo kwakira no kugurisha)?

Iyo bisobanuwe muri PO / ITP, ibintu bisanzwe byinjira birimo:nka - yubatswe anode urutonde / indangamuntu, kwishyiriraho / gufunga kugenzura urutonde, nibisabwa byosegukomeza / kwipimisha ikizaminihiyongereyeho gusana / re - ibiti byo kugerageza niba gusana byarakozwe. Ubuyobozi ngenderwaho bushimangira kubika ibishushanyo mbonera, kugenzura / kugerageza, hamwe ninyandiko nkigice cyanditse.
