1. ƝƐFƆLI ƝƐFƆLI- nɛgɛ pipe min bɛ se ka wuli: nɛgɛ pipe ni lakana layini caman .
A kɔnɔna na, corrosion- steel pipe min bɛ se ka wuli, o ye nɛgɛ pipe kɔrɔlen ye hali bi (i n’a fɔ fɛn min tɛ fɛn tiɲɛ, min bɛ sɔgɔ ni sumaya ye, walima min bɛ kɛ ka ɲɛ-seam welded), nka a bɛ danfara don o la, fɛn min bɛ se ka kɛ ni fɛn ye min bɛ se ka kɛ ka a kɔnɔna ni a kɛnɛma. O lakanani layiniw bɛ se ka tila ka kɛ kulu saba ye ka da fɛn ni taabolo kan minnu bɛ kɛ: dacogo, finimugu, ani kuran-sɛnɛfɛnw lakanani. Coating ye o fɛɛrɛ ninnu bɛɛ la belebele ye.
Datugulan minnu bɛ kɛ ka caya, olu ye epokisi mugu dacogo ye (FBE), saba{0}}poliɛtilɛni (3PE), poliyetilɛni nɔrɔlan, ani poliyuritan. Ni a bɛ 3PE ta misali la, a bɛ kɛ ni epoyi mugu basigilen ye (a bɛ nɔrɔ barikama di nɛgɛ pipe ni kemikaliya la), a cɛmancɛ la, a bɛ nɔrɔ (a bɛ epokisi layɛrɛ siri kɛnɛma poliyetilɛni la), ani poliyetilɛni kɛnɛma (a bɛ tali kɛ tiɲɛni na min bɛ kɛ ni masin ye ani UV ye). Nin saba-Layɛrɛ sigicogo bɛ baara kɛ ɲɔgɔn fɛ walasa ka bɔgɔ ni kɔgɔji nɔgɔli kunbɛn, ka sɔrɔ ka farikolo-ɲɛnajɛ fana muɲu ni a sutura walima a sanfɛ.
2. Anti-Pupe min bɛ kɛ ni nɛgɛ ye, o ka "protection logique": fɛn saba bɛ sɔrɔ nɔgɔ kunbɛnni kama .
Nɛgɛ nɔgɔli ye fɛn ye min bɛ se ka kɛ fɛn ye min bɛ se ka kɛ ni kuran ye. Ni nɛgɛ pibilikiw bɛ don ji, ɔkisizɛni ani elekitoroliti la (i n’a fɔ kɔgɔ bɛ dugukolo la), selilɛri galvanic (gavanique) bɛ sɔrɔ, o bɛ kɛ sababu ye ka nɛgɛ atomu (atomu) bɔnɛ elekitoronikiw la ani ka oksidan kɛ (a bɛ kɛ nɔgɔ ye). corrosion- resistant steel pipes bɛ nin wale in bali nin fɛɛrɛ ninnu fɛ:
Farikolo yɔrɔw danfara: Datugulanw walima finimuguw (i n’a fɔ poliyetilɛni walima seramiki) bɛ nɛgɛ pipe bɔ ɲɔgɔn na pewu ka bɔ fɛnɲɛnamafagalan na, o bɛ a bali ka ɲɔgɔn sɔrɔ tilennen na.
Pasisiki kemikali : finimugu dɔw (i n’a fɔ epoyi mugu) bɛ kɛ ni nɛgɛ pipe sanfɛla ye walasa ka passivation film dense kɛ, ka elekitɔnw cili bali.
Kuranko lakanani : Katodiki lakanani (ICCP) fɛɛrɛ min bɛ mɔgɔ kabakoya (a ka c’a la, o bɛ kɛ ni finimugu ye) bɛ kɔfɛlafɛn dɔ kɛ nɛgɛdaga la, k’a tigɛli kɛ katodi ye, o bɛ a bali ka sɔgɔ i n’a fɔ anɔdi.
Misali la, tulu ni gazi pibiliki suturalenw kama, 3PE dacogo bɛ ji ni kɔgɔ doncogo kɛlɛ ka bɔ bɔgɔ la, ka sɔrɔ katodiki lakanani fɛɛrɛ bɛ lakana wɛrɛ di, ka nɔgɔ bɔli nɔgɔya hali ni finimugu yɔrɔ dɔ tiɲɛna.
3. Seko ni dɔnko karti min bɛ kɛ ni nɔgɔ ye- nɛgɛ pipew minnu bɛ se ka wuli: ka ladamu cogoya wɛrɛw la .
Sɔgɔsɔgɔninjɛ lakanani wajibiyalenw bɛ danfaraba la izini suguya caman na, o bɛ na ni nɛgɛ pipe suguya suguya caman ye minnu bɛ se ka wuli ka bɔ u nɔ na, minnu dabɔra ka sigida gɛlɛya kɛrɛnkɛrɛnnenw ɲɛnabɔ:
Pibiliki surilenw kama: 3PE walima epoxy coal tar coatings de ka fisa. Fɔlɔ bɛ se ka dugukolo degun ni jiriw ju doncogo kɛlɛ, o b’a to a bɛnnen don gazi nafama ni tulumafɛnw tacogo la; Nin laban in ka dɔgɔ- musaka ni ji- bɛ se ka baara kɛ ni a ye ji la ani jibolisiraw la.
Kɔgɔjida laminiw: Kɔgɔji caman sɔrɔli, UV fiɲɛ barikamaw, ani kɔgɔji jiginni, epoxy mugu + poliyuritani kɛnɛma sheath walima titanium nano-Nasi pipe min bɛ kɛ ka ɲɛ, o bɛnnen don kosɛbɛ, ni kɔgɔ fiyɛli bɛ se ka kɛ san 20 ni kɔ kɔnɔ.
High-Semperature and High-Dafasa sigidaw: Ka ɲɛsin funteni fanga rezow ma walima kemikaliya waleyali pibilikiw ma, seramiki dacogo walima sanfɛ{2}}sumalan epokisi dacogo (min bɛ se ka funteni muɲu ka tɛmɛ degere 300 kan ) o bɛ fɔ, o bɛ kɛ sababu ye ka sɔgɔli ni funteni tiɲɛni kunbɛn.
Kunnafoni kɛrɛnkɛrɛnnenw : Ni aw bɛ asidi ni alkalini (i n’a fɔ asidi sulfuriki ni liye), politetarafluoroethylene (PTFE)-Sɛnɛfɛnw pipe de ka kan ka kɛ. A ka kemikaliya inertness b’a to a bɛ se ka ji minnu ka surun kosɛbɛ, olu bɛɛ bɛ se ka kɛ.
4. Anti-Nafolo pipew nafa: Sɔrɔ ni lakana garanti fila .
Nafa minnu bɛ sɔrɔ sɔrɔko la, n’o ye ka anti-nɔgɔ pipew sɔrɔ, olu nafa ka bon. Nɛgɛbere gansanw bɛ se ka kɛ wajibi ye ka bila u nɔ na 3- san 5 o sanw na, ka sɔrɔ sanfɛ-Quality anti-Nɛgɛ pipew bɛ se ka mɛn 20-50 san 50 (misali la, 3PE anti-corrosion suturaw bɛ dilan cogoya la san 50 kɔnɔ). Misali la, gazi nafama pibiliki bɔli min bɛ sɔrɔ nɔgɔ ni bɔgɔbɔli fɛ, o bɛ se ka kɛ sababu ye ka sɔrɔko bɔnɛ tilennen sɔrɔ min bɛ se miliyɔn kɛmɛ caman ma. Nka, wari bilali nɛgɛberew la, o bɛ kɛ 5%-15% dɔrɔn ye pibiliki musaka bɛɛ lajɛlen na, o bɛɛ n’a ta, a bɛ se ka kasaara farati dɔgɔya ni 90% ni kɔ ye.
Ka fara o kan, anti-Nafe pipew bɛ kɛ ka ɲɛ ni u ka dɔgɔ-karɔbɔni yiriwali. Nɔgɔ bɛ dɔ bɔ pibiliki nafa la (misali la, sɛgɛsɛgɛli bɛ dɔ fara farikolo tangali kan), ka sɔrɔ anti-Corosion furakɛli bɛ pibiliki kɔnɔna nɔgɔlen mara, ka fanga bɔnɛ dɔgɔya. Ni aw bɛ baarakɛ waati janya, o bɛ dɔ bɔ nɛgɛdaga fililenw ka sigida la.
Kuncɛli: "Kɔlɔsilikɛla yebali" min bɛ ɲɛnamaya sira lakana .
K’a ta tilebin yanfan fɛ-Kɔrɔn gazi pibiliki rezow la ka se kɔgɔjida la kemikɛli iziniw ka fɛnw jiginni ma, k’a ta dugubaw kɔnɔ dugujukɔrɔjiw la ka se polar ɲininikɛyɔrɔw ka fanga pibilikiw ma, anti-Nafolo pibilikiw bɛ bi iziniw ka lakana n’u ka baarakɛcogo ɲuman lakana u makun na. Ni ɲɛtaa bɛ fɛnw dɔnniya la ani anti{3}}Sɔrɔli fɛɛrɛw la (i n’a fɔ nano-coatings ani monitoring monitoring anti{5}}corrosion layers), anti-Roosion Steel pipes nataw bɛna kɛ hakilitigiw ye ka tɛmɛn fɔlɔ kan, ka taa a fɛ ka kɛ jusigilan jɔnjɔn ye diɲɛ fanga ni fɛnsɔrɔsiraw la.
