Tlhahlobo e Felletseng ea Litlhokomeliso Bakeng sa ho Sebelisa{0}}Anti{0}corrosion Steel Pipe
Ka lebaka la matla a eona a ho thibela kutu, peipi e thibelang ho bola ha{0}e sebelisoa haholo indastering ea petroleum, lik'hemik'hale, khase ea tlhaho le phepelo ea metsi. Leha ho le joalo, ho hlokomoloha litemoso tsa bohlokoa nakong ea ts'ebeliso ho ka lebisa ho se sebetseng ha -ho corrosion coating, ho khutsufatsa nako ea bophelo ba liphaephe esita le ho baka likotsi tsa polokeho. Lintlha tse latelang mabapi le litemoso tsa ho sebelisa{4}}peipi ea tšepe e thibelang kutu ho tsoa likarolong tse 'ne: lipalangoang, ho kenya, ho sebetsa le tlhokomelo.
I. Lipalangoang: Qoba Ho Senya 'Meleng
The anti{0}corrosion coating of anti-corrosion steel coating (jwalo ka 3PE, epoxy powder, le tse ding) e senyeha ha bonolo ke ho thula, ho hohla, kapa ho petetsa nakong ya sepalangwang. Ka hona, ka kopo hlokomela:
Loading e Nepahetseng: Sebelisa litšehetso tse inehetseng kapa cushioning e bonolo ho tiisa phala ea tšepe le ho qoba ho kopana ka kotloloho le lintho tse thata. Sebelisa esita le matla ha u tlama ho thibela lesela hore le se ke la khangoa.
Ho itšireletsa puleng le mongobo: Koahela ka seile e sa keneleng metsi nakong ea lipalangoang, haholo-holo bakeng sa liphahlo tsa epoxy{{0}based anti{1}}anti-corrosion, kaha ho kopana le metsi ho ka fokotsa ho khomarela ha tsona.
Phahamisa 'me U Behe ka Tlhokomeliso: Sebelisa li-slings tse inehetseng nakong ea ho phahamisa, 'me u qobe ho kopana ka ho toba pakeng tsa thapo ea terata le phala. Lintlha tsa ho phahamisa li lokela ho qoba li-welds kapa libaka tse fokolang ka ho roala.
II. Mokhoa oa ho kenya: Ho Fokotsa Tšenyo
Ho kenngwa ke boemo bo kotsi- bo phahameng ba tshenyeho ya-anti-corrosion coating. Ela hloko ka ho khetheha lintlha tse latelang:
Pipe End Protection: Pele o seha kapa o tjheseletsa, koala sekoahelo se thibelang ho bola{0}lipeipi qetellong ka theipi kapa likatiba tsa polasetiki ho thibela ho chesoa ke litlhase tse fofang.
Litlhoko tsa Welding: Haeba-saeteng ho hlokahala, siea lekhalo la 10-15cm pakeng tsa seam le se thibelang kutu. Etsa kopo hape ka mor'a hore welding e felile. Ho sebetsa pula, lehloa, kapa tikolohong e nang le mongobo o fetang 85% ho thibetsoe ka thata.
Litaelo tsa ho Tšoara: Apara liatlana ha u li tšoara ka letsoho ho thibela ho bola ho tsoa mofufutso oa letsoho. Nakong ea ho sebetsana le mechine, fetola sebaka sa li-roller ho thibela ho kobeha le ho senyeha ha phala.
III. Mohato oa Ts'ebetso: Ho Laola Tikoloho le Khatello
Ts'ebetso ea nako e telele-ea{1}}ea phala e thibelang ho bola e amana haufi-ufi le tikoloho ea ts'ebetso:
Phatlalatso ea Mecha ea litaba: Netefatsa hore mokhoa oa ho fetisa (mohlala, maro a asiti le alkaline,{2}}mouoane o phahameng) o lumellana le{3}}mofuta oa li-corrosion coating. Mohlala, phofo ea epoxy e na le asiti-e hanana le lihlapolli tse matla.
Meeli ea Mocheso le Khatello: Khomarela ka thata ho li-parameter tsa moralo. Lithempereichara tse feteletseng li ka 'na tsa etsa hore seaparo se be bonolo ebe se oa,' me khatello e phahameng e ka baka khatello ea kelello habonolo. Khokahano ea Tšireletso ea Cathodic: Liphaephe tse epetsoeng li hloka tlhahlobo ea khafetsa ea bokhoni ba ts'ireletso ea cathodic (hangata -0.85V ho -1.2V) ho netefatsa ts'ireletso ea lik'hemik'hale tsa motlakase libakeng tse senyehileng tsa coating e thibelang kutu.
IV. Tlhokomelo le Tlhahlobo: Lokisa Litšitiso Hang-hang
Tlhokomelo ea kamehla e ka lelefatsa bophelo ba-lipeipi tsa tšepe tse thibelang kutu ka makhetlo a mangata:
Tlhahlobo ea Ponahalo: Hlahloba ka mahlo hore na ho na le seaparo se pota-potiloeng, ho phunyeha kapa ho phunya bonyane selemo le selemo, u shebane le libaka tsa khatello ea kelello tse kang li-welds le litsoe.
Teko ea Electro-spark: Liphaephe tse epetsoeng li lokela ho hlahlojoa ha ho na masoba ka har'a coating ho sebelisoa mochini o hlahlobang motlakase-ka mor'a lilemo tse ling le tse ling tse 2-3. Ho dutla ho lokela ho lokiswa ka pente e thibelang kutu kapa teipi e honyesang mocheso.
Tlhoekiso ea Tikoloho: Tlosa lehola le li-depositi tse senyang (joalo ka saline-mobu oa alkali) ho potoloha lipeipi ho thibela ho bola ho bakoang ke likokoana-hloko (MIC).
Qetello
Melemo ea ts'ebetso ea liphaephe tse thibelang{0}}anti-corrosion lipeipi li ipapisitse le taolo e felletseng le e tloaelehileng. Ho latela ka tieo litemoso tse boletsoeng ka holimo mohatong o mong le o mong, ho tloha ho lipalangoang ho isa ho lahleloa, ho netefatsa hore ho na le tšireletso e feletseng{2}}ea tšebetso ea tsamaiso e sireletsehileng le e tsitsitseng. Bakeng sa maemo a khethehileng a ho sebetsa (a kang leoatle le tebileng le tikoloho e matla ea acid), ho kgothaletswa ho buisana le moetsi bakeng sa tharollo e hlophisitsoeng mme o se ke oa sebetsa ka bofofu.
