Uhlahlelo oluGqibeleleyo lweMiqathango yokuSebenzisa i-Anti{0}}i-Corrosion Steel Pipe
Ngenxa yokumelana nokugqwesa kwayo okugqwesileyo, umbhobho wentsimbi wokuchasana-usetyenziswa kakhulu kwipetroleum, imichiza, irhasi yendalo, kunye nobonelelo lwamanzi. Nangona kunjalo, ukutyeshela izilumkiso ezingundoqo ngexesha lokusetyenziswa kunokukhokelela ekungasebenzini kwe-anti{2}}i-corrosion coating, ukunciphisa ubomi bombhobho kwaye kubangele iingozi zokhuseleko. Ezi nkcukacha zilandelayo izilumkiso zokusebenzisa-umbhobho wentsimbi wokubola ukusuka kwimiba emine: uthutho, ufakelo, ukusebenza, kunye nokugcinwa.
I. Ezothutho: Kuphephe Ukwenzakala Emzimbeni
I-anti{0}}i-corrosion coating ye-anti{1}}yentsimbi yombhobho wentsimbi (efana ne-3PE, i-epoxy powder, njl.njl.) yonakaliswa lula kukungqubana, ukukhuhlana, okanye ukucinezelwa ngexesha lothutho. Ngoko ke, nceda uqaphele:
Ukulayishwa ngokufanelekileyo: Sebenzisa izixhaso ezizinikezeleyo okanye i-soft cushioning ukukhusela umbhobho wensimbi kwaye ugweme ukudibanisa ngokuthe ngqo izinto ezinzima. Faka amandla xa ubopha ukuthintela ukukrwitshwa kwengubo.
Ukukhusela kwimvula kunye nokufuma: Gquma ngeseyile engangeni manzi ngexesha lothutho, ingakumbi kwi-epoxy{0}}esekelwe kwi-anti{1}}i-corrosion coatings, njengoko ukudibana namanzi kunokunciphisa ukuncamathela kwazo.
Phakamisa kwaye ubeke ngokunyamekela: Sebenzisa izilingi ezizinikeleyo ngexesha lokuphakamisa, kwaye ugweme ukudibanisa ngokuthe ngqo phakathi kwentambo yocingo kunye nombhobho. Amanqaku okuphakamisa kufuneka aphephe i-welds okanye iindawo ezibuthathaka kwi-coating.
II. Inkqubo yokuFakela: Ukunciphisa Umonakalo
Ukufakela linqanaba eliphezulu{0}}lomngcipheko womonakalo kwi-anti{1}}ityabeka lokutya. Nika ingqwalasela eyodwa kwezi nkcukacha zilandelayo:
Umbhobho woKhusela uMbhobho: Phambi kokusika okanye ukuwelda, vala i-anti{0}}i-corrosion coating kumbhobho uphela ngeteyiphu okanye iminqwazi yeplastiki ukunqanda ukutsha kwiintlantsi ezibhabhayo.
IiMfuneko zokuwelda: Ukuba{0}}kwisiza ukuwelda kuyafuneka, shiya i-10{2}}15cm isithuba phakathi kweweld seam kunye ne-anti-corrosion coating. Phinda ufake i-coating emva kokuba i-welding igqityiwe. Ukusebenza emvuleni, kwikhephu, okanye kwiindawo ezinomswakama ongaphezulu kwe-85% akuvumelekanga ngokungqongqo.
Imiyalelo yokuphatha: Nxiba iiglavu ngexesha lokuphatha ngesandla ukunqanda ukubola kokubila kwesandla. Ngexesha lokuphatha ngomatshini, lungisa isithuba se-roller ukukhusela ukugoba kunye nokuguqulwa kombhobho.
III. Isigaba sokuSebenza: Ukulawula iNdawo kunye noxinzelelo
Ukusebenza kwexesha elide-lombhobho wentsimbi wokuchasana{1}}ngokusondeleleneyo nemeko yokusebenza:
IMedia Compatibility: Qinisekisa ukuba indawo ehambisayo (umzekelo, ulwelo oluneasidi kunye nealkaline,-ubushushu obuphezulu bomphunga) luhambelana nohlobo oluchasene{3}}nokutya kokutya. Umzekelo, umgubo we-epoxy uneasidi{5}}iyaxhathisa kodwa ayixhathisi kwizinyibilikisi ezinamandla.
Iqondo lobushushu kunye neMida yoxinzelelo: Bambelela ngokungqongqo kwiiparamitha zoyilo. Amaqondo obushushu agqithisileyo anokubangela ukuba i-coating ithambe kwaye iwe, kwaye uxinzelelo oluphezulu lunokubangela lula ukuqhekeka koxinzelelo. Ulungelelwaniso loKhuseleko lweCathodic: Imibhobho engcwatywayo ifuna ukuvavanywa rhoqo amandla okukhusela i-cathodic (ngokuqhelekileyo -}0.85V ukuya -1.2V) ukuqinisekisa ukukhuselwa kwe-electrochemical kwiindawo ezonakalisiweyo ze-anti-corrosion coating.
IV. ULondolozo kunye noHlolo: Lungisa ngokukhawuleza iziphene
Ukugcinwa rhoqo kunokwandisa ubomi bemibhobho yentsimbi echasene -nokonakala amaxesha amaninzi:
Ukuhlolwa kwenkangeleko: Hlola ngokubonakalayo i-coat yokugquma, ukuqhekeka, okanye ukuxobula ubuncinci ngonyaka, ugxininise kwiindawo zokuxininisa uxinzelelo ezifana ne-welds kunye ne-elbows.
I-Electro-Uvavanyo lwentlantsi: Imibhobho egqunyiweyo kufuneka ihlolwe imingxuma yepina ekwicoating kusetyenziswa i-electro{1}}spark tester rhoqo nge-2-3 iminyaka. Ukuvuza kufuneka kulungiswe ngepeyinti yokunqanda ukubola okanye iteyiphu yokunciphisa ubushushu.
Ucoceko lokusiNgqongileyo: Susa ukhula kunye needipozithi ezidliwayo (ezifana netyuwa{0}}yomhlaba wealkali) ojikeleze umbhobho ukunqanda ukonakala okunefuthe kwi-microbiologically influenced (MIC).
Ukuqukumbela
Iinzuzo zokusebenza ze-anti{0}}yemibhobho yentsimbi yokubola ixhomekeke kulawulo olubanzi nolusemgangathweni. Ukuthotyelwa okungqongqo kwezi zilumkiso zingentla kwinqanaba ngalinye, ukusuka ekuthuthweni ukuya ekulahlweni, kuqinisekisa ngokupheleleyo-isiphumo sokutya kunye nokusebenza okukhuselekileyo nokuzinza kwenkqubo. Kwiimeko ezikhethekileyo zokusebenza (ezifana nolwandle olunzulu kunye nommandla oqinileyo we-asidi), kuyacetyiswa ukuba udibane nomenzi wezisombululo ezenziwe ngokwezifiso kwaye ungasebenzi ngokungaboni.
