Nkwalite na Teknụzụ Anticorrosion Steel Pipe na-echebe nchekwa na ogologo ndụ nke ụgbọ njem ụlọ ọrụ
N'ime mmanụ ala petrochemical, mmiri nke ime obodo, na mpaghara ụgbọ njem gas, ọkpọkọ ígwè, dị ka ụgbọ ala ndị bụ isi, na-ekpughere ọtụtụ ihe ịma aka, gụnyere mmebi ala, mbuze mgbasa ozi, na ikuku oxidation.

Site na nkwalite ụlọ ọrụ mmepụta ihe na ihe nchekwa gburugburu ebe obibi dị elu, teknụzụ anticorrosion ígwè anwụrụ esiwo na nchebe otu mkpuchi gaa na ọkwa ọhụrụ nke nchebe ndụ zuru oke nke gụnyere "mmelite ihe onwunwe, njikarịcha usoro, na nleba anya nke ọgụgụ isi."
Ka ọ dị ugbu a, teknụzụ anticorrosion nchara nchara na-enye usoro dị iche iche ahaziri dabere na ọnọdụ ngwa akọwapụtara. Na mpaghara pipeline e liri, 3PE (ihe mkpuchi polyethylene atọ) mkpuchi mgbochi corrosion bụ ihe ngwọta kachasị mma maka mmanụ dị anya na pipeline gas n'ihi nguzogide ha dị mma na nrụgide ala na nkwụsị nke cathodic. Nhazi ha mejupụtara, nke nwere ntụ ntụ epoxy isi, nrapado etiti, na oyi akwa polyethylene dị n'èzí, na-enye ma corrosion na mmetụta nchebe. Maka pipeline acid na alkaline na ụlọ ọrụ kemịkalụ, mkpuchi fluorocarbon na mkpuchi plastik na-enye uru. Nke mbụ na-etinye aka na inertness kemịkalụ nke fluororesin iji guzogide mgbasa ozi na-emebi emebi, ebe nke ikpeazụ na-ekewapụ mgbasa ozi na-ebufe site na ọkpọkọ ígwè n'onwe ya site na iji ihe ndị dị ka polyethylene na polytetrafluoroethylene kpuchie mgbidi dị n'ime. Ọzọkwa, a na-eji galvanizing na-ekpo ọkụ na-ekpo ọkụ n'ọtụtụ ebe na gburugburu ebe obibi dị nro dị ka mmiri nke ime obodo na usoro drainage na ihe owuwu ígwè na-akwado n'ihi ọnụ ala ya na ntinye dị mma. Omume anodic nke akwa zinc na-enye nchebe electrochemical na-adịte aka maka ọkpọkọ ígwè.
Nkwalite nkà na ụzụ na usoro ihe ọhụrụ na-eme ka ọ dịkwuo mma n'ịdị mma nke mgbochi corrosion ígwè. Usoro eserese akwụkwọ ntuziaka ọdịnala, n'ihi okwu ndị dị ka ọkpụrụkpụ mkpuchi na-enweghị isi na nrapado na-adịghị mma, ejiri ahịrị mmepụta akpaghị aka dochie nke nta nke nta. Mgbasa electrostatic nke ugbu a na teknụzụ ịgba ikuku na-enweghị ikuku nwere ike nweta nnabata ọkpụrụkpụ mkpuchi n'ime ± 5%. N'ọhịa nke ihe mgbochi corrosion, mkpuchi mmiri epoxy na-eme ka mmiri dị na gburugburu ebe obibi na graphene-modified anti-corrosion coatings na-eji nwayọọ nwayọọ dochie ihe mgbaze dabeere na ihe mgbaze, na-ebelata ikuku VOC ka ọ na-eme ka mkpuchi ihu igwe na-eguzogide ma na-eyi nguzogide. N'otu oge ahụ, ụzọ nlekota ọgụgụ isi na-amalite ịbanye n'ime usoro mgbochi corrosion. Ọkpụkpọ ígwè n'ụfọdụ isi ọrụ nwere ihe mmetụta corrosion ugbu a. Ihe mmetụta ndị a na-anakọta ihe nrịbama corrosion nke dị ugbu a na mkpuchi mkpuchi sitere na mgbidi dị n'elu pipeline, na-enye ịdọ aka ná ntị mmalite maka ihe egwu ọdịda corrosion na nrụzi ziri ezi.
Maka ọrụ mgbochi corrosion ígwè ọkpọkọ, nkwekọrịta ụlọ ọrụ bụ na "ihe 30%, 70% ewu." Tupu e wuo ya, a ghaghị iji ájá dị nchara nchara iji wepụ nchara ma hụ na ọ dị elu nke Sa2.5 ma ọ bụ karịa. Ọgwụgwọ a na-ewepụkwa ihe ndị na-adịghị ọcha dị ka mmanụ, ọnụ ọgụgụ, na adịghị ọcha ndị ọzọ, na-emeghe ụzọ maka mkpuchi mkpuchi.
