Sisan, aw bɛ farikolo baarakɛcogo, saniya kɛcogo, fɛnw tiɲɛni ani u nafa sɔrɔ sɔrɔko siratigɛ la, olu suma ɲɔgɔn na.
1) farikolo yɔrɔw sumacogo .
Tensile fanga sumacogo:
Ni aw ye nɛgɛbere finman min bɛ kɛ ni nɛgɛ ye, n’a bɛ kɛ ni nɛgɛ ye, n’a bɛ kɛ ni 304 ye, n’a bɛ kɛ misali ye, n’a ka fanga ye 530-750MPa ye, n’o ye galɔn pipe ta siɲɛ fila ye, ani nɛgɛdaga ta siɲɛ saba. O de kama, nɛgɛ finman min bɛ kɛ ni nɛgɛ ye, o bɛ se ka kɛ fɛn finman ye (0,6mm) ka tɛmɛ kuran pipe kan, min bɛ bɛn jamana ka izini politiki ma min ye fɛnw marali ye, fanga garanti bɛ a la, wa a bɛ se ka kɛ sababu ye ka sow doni dɔgɔya
2) Sumayako ɲɛnabɔli sumacogo:
Pipe inox thin-walled thin-walled conductivity ye 15 w/m°C (100°C) ye, o ye 1/4 ye ka bɔ pipe carbone la ani 1/23 ta la kuran pipe la. Kogo finmanw pipew bɛnnen don kɛrɛnkɛrɛnnenya la ji funteni tacogo la k’a sababu kɛ u ka funteni sɛgɛsɛgɛli baara ɲuman ye. A kɛra insulasi layini girinya ye wo, walima insulation structure jɔli n’a ladonni musakaw ye wo, kogo finman intansi pibilikiw bɛ ni sɔrɔko nafa ɲuman ye.
3) Sumaya bonya coefficients (jatebɔ) sumacogo :
Pipe minnu bɛ kɛ ni nɛgɛ ye, olu ka funteni bonya hakɛ mumɛ ye 0,017mm/(m°C) ye, o min bɛ surunya nɛgɛberew la. Nɛgɛ pibilikiw ka kan ka kɛ ji funteni tacogo la.
Tubu min bɛ kɛ ni nɛgɛ ye min bɛ kɛ ni nɛgɛ ye, o kɔnɔna kogo bɛ nɔgɔya kɔnɔna ni kɛnɛma furakɛli kɔfɛ, ani tubabu kɔnɔna kogo gɛlɛn ks ɲɔgɔnna ye 0,00152mm ye, o min ka dɔgɔn ni kuran tuubu ta ye.
O la, baara min bɛ kɛ ni kogo finmanw ye, o bɛ ji bɔ, ji bɛ taa ka ɲɛ, a bɛ se ka sɔgɔ ka ɲɛ, wa a bɛ mankan dɔgɔya kosɛbɛ .
2. Saniya baarakɛcogo suma .
Jibolisira min bɛ kɛ ni nɛgɛ ye, o bɛ gɛlɛya ban 'ji bilenman, ji buluma ani ji dogolen'. A kasa kɛrɛnkɛrɛnnen tɛ, scaling tɛ a la, fɛn jugu sanji tɛ a la, a bɛ ji cogoya saniya, wa a tɛ kojugu kɛ hadamaden farikolo la.
Dunanw ka baarakɛcogo ni laboratuwaari sɛgɛsɛgɛliw kɛra jamana wɛrɛw la san tan caman kɔnɔ, o y’a jira ko nɛgɛ minnu bɛ kɛ nɛgɛ ye, olu sanji hakɛ ka ca ni 5% ye, o min bɛ sɔrɔ OMS ni Erɔpu ji minta sariya fɛ (jamana bɛɛ bɛ nin sariya fila in kofɔ). Fɛ́gɛn.
Tiɲɛ na, nɛgɛ min tɛ sɔgɔ, o yɛrɛ ye farati ye, a tɛ baga ye, wa a saniyacogo ɲumanw bɛ a la, minnu sɛgɛsɛgɛra kosɛbɛ ni nɛgɛ nɔgɔlen tali ye san tan caman kɔnɔ, minnu bɛ tali kɛ hadamadenw ka kɛnɛya la, wa u kɛra tiɲɛ ye min bɛ dɔn kosɛbɛ.
Nɛgɛ min tɛ sɔgɔ, o ma kɛ dɔrɔn dumuniko siratigɛ la, minfɛnw, nɔnɔko, nɔnɔko, furakɛli, tabalifɛnw ani tobilikɛminɛnw, wa a kɛra fɛn ye min bɛ kɛ ka kɛɲɛ ni sariya ye nin baara ninnu na, nka a bɛ kɛ fana furakɛli hadamadenw ka fɛnw na minnu bɛ se ka kɛ fɛn ye min ka bon kosɛbɛ ani ka saniya i n’a fɔ bracket suguya caman, joli-sira-funu ani nɛgɛw bɛ kɛ ka saniya kɛ farikolo la, a ɲɔgɔnnaw., ani a bɛ kɛ fɛn ye min bɛ kɛ ka fɛnw saniya. Saniya ka bon kosɛbɛ.
A dɔnna kosɛbɛ ko nɛgɛberew ka teli ka sɔgɔ ani ka patina bɔ.
Kupu pibilikiw bɛ tɔɔrɔ ni nɛgɛ tɛmɛnen ye, kasa duman nɔgɔlen bɛ bɔ ji buluma na ka da a sɔgɔli kan, ani a sɔgɔli. 'patinous green' min bɛ sɔrɔ kuran pipew la, o bɛ kɛ kɛrɛnkɛrɛnnenya la ni kuran karɔbɔni ye, kuran idɔrɔkisidi fɛnɲɛnamafagalan [Cuco3.cu(on)2] ani kuran sulfate (CUSO4), o min ka nɔgɔn ka waati kɛ ani ka a wuli ji la. Hali ni a bɛ se ka ɲɛgɛnɛsiraw bali, a tɛ se ka banakisɛw ka nɔ bila a la, o tɛ ɲɛ, a bɛ baga ma ani fana a bɛ kɛ fɛnɲɛnamafagalanw ye, minnu bɛ se ka wuli, ka mɔgɔ bila ka fɛnw lawuli ani ka u sɔgɔ hadamaden farikolo la.
A bɛ se ka kɛ sababu ye ka fɔɔnɔ reflex ani a bɛ se ka kɛ sababu ye ka banakɔtaa kɛ. Bi furakɛli ɲininiw y’a jira ko ji minta ni nɛgɛ ye kojugu (a kɛra ji buluma hakɛ ye walima a ma se) o bɛ tiɲɛni kɛ kosɛbɛ kɛnɛyako la.
3. ka sɔgɔsɔgɔninjɛ kunbɛn .
Ikomi nɛgɛbere finman min bɛ kɛ ni nɛgɛ ye, o bɛ se ka baara kɛ ni oksidan ye, ka oksizɛni lakanani filimu gɛlɛn ni chrome-rich (kɔrɔmu) kɛ chromium trioxide (CR2O3) sanfɛla la, o bɛ se ka oksidan waleyali kɛcogo wɛrɛw bali ka ɲɛ, k’a sɔrɔ kuran tuubu ka se ka baara kɛ ka ɲɛ kosɛbɛ. O de ye sababuba ye min b’a to nɛgɛberew ka nɔgɔli bɛ dɔgɔya kosɛbɛ ni nɛgɛberew ye minnu kogow ka fin.
Ni aw bɛ baara kɛ ni nɛgɛberew ye, a ka kan ka ji ka kemikaliya ni a teliya kɔlɔsi, n’o tɛ a bɛna kɛ sababu ye ka pipew nɔgɔya. Misali la, kuran pibilikiw sɔgɔli bɛna caya kosɛbɛ ji la ni pH<6,5 walima kulori tolen hakɛ>70ppm ye, wa ji nɔgɔlen fana bɛna kɛ sababu ye ka sɔgɔli caya. Ni kuran pipew bɛ baara kɛ, ji teliya man kan ka tɛmɛ m/s 2 kan, n’o tɛ, nɔgɔ hakɛ bɛna caya kosɛbɛ.
Ni jibɔ hakɛ sera mɛtɛrɛ 2/s ma, nɛgɛ pipe ka nɔgɔ hakɛ bɛ se siɲɛ 3 ma, nɛgɛdaga min bɛ kɛ ni nɛgɛ ye, n’a kogo ka fin, ani ni jibɔ hakɛ ka bon ni m/s 6 ye, o hakɛ bɛ se ka kɛ nɛgɛ ye min tɛ ko kogo finman ye, o siɲɛ 20 ye.
Ka fara o kan, kuran pipe sanfɛla fana sɔgɔli ka nɔgɔn.
4. Sɔrɔko nafa sumacogo .
Chrysler boon min bɛ New York, Ameriki, o jɔra san 1926 ni 1931 cɛ.A janya ye mɛtɛrɛ 318,9 ye, a sanfɛla ye mɛtɛrɛ 77 ye. O ye boon fɔlɔ ye diɲɛ kɔnɔ min bɛ baara kɛ ni nɛgɛ ye min tɛ sɔgɔ a kɛnɛma.
Hali n’a sigiyɔrɔ bɛ kɔgɔjida la ani a nɔgɔlen don, nɛgɛ min tɛ sɔgɔ, o bɛ yeelen bɔ hali bi san 80 kɔfɛ, saniya fila dɔrɔn de bɛ a ni ɲɔgɔn cɛ.
Ka bɔ Chrysler boon na New York, Petronas Towers min bɛ Kuala Lumpur ka taa Disney Concert Hall la Los Angeles, min dilannen don ni nɛgɛ ye min tɛ sɔgɔ, ani Waterloo nɛgɛsobon min bɛ Lɔnduru, Angletɛri; Ka ɲɛsin jɔli yɔrɔw ma, nɛgɛ min tɛ sɔgɔ, i n’a fɔ boonw dilanni fɛn min bɛ sabati ka tɛmɛ fɛn tɔw bɛɛ kan, o bɛ fɛn dɔ bɔ min ɲɔgɔn tɛ, fɛn gansanw tɛ min na diɲɛ fan bɛɛ.
Ninnu ye misali ɲumanw ye minnu bɛ kɛ ni nɛgɛ ye min tɛ waati bɔ.
K’a ta nɛgɛdaga finmanw baaracogo sɛgɛsɛgɛli la jamana kɔnɔ ani jamana kɔkan, nɛgɛso kogo finmanw ni jibolisiraw ka baarakɛ waati ni sow ta ye kelen ye, o min bɛ bɛn nɛgɛberew ta ma.
Teori girinya jateminɛ formula min bɛ kɛ ni kogo finman ye min tɛ sɔgɔ:
Kisɛ hakɛ jateminɛnan kelen na = (kɛnɛma cɛmancɛ - a janya) × a janya × PI × density ÷ 1000 .
Pibilikiw sɔngɔ suma ɲɔgɔn na : K’a sababu kɛ nɛgɛmafɛnw sɔngɔ ka bon, nɛgɛ pipew sɔngɔ ka bon kosɛbɛ, wa, nɛgɛmafɛnw sɔngɔ ka dɔgɔ ni nɛgɛ ye min tɛ sɔgɔ, o bɛ dɔgɔya 40% ɲɔgɔn na ka tɛmɛ kuran pipew ta kan. O la, a jɛlen don ko a jɛlen don ko pipe inox kogo finmanw ka fisa ni nɛgɛberew ta ye.
Pibiliki minnu bɛ kɛ ni nɛgɛ ye, olu ka ɲɛnamaya kɛcogo musaka ka dɔgɔ ni nɛgɛberew ye.
Sabula ni baara kɛra ni nɛgɛdaga finmanw ye, u mago tɛ ka wuli ka bila u nɔ na san 100 ɲɛnamaya kɔnɔ, k’a sɔrɔ pipe wɛrɛw tɛ se ka baara kɛ waati jan kɔnɔ. Ni u jiginna siɲɛ kelen boon kɔnɔ san 70 kɔnɔ, a musaka bɛɛ bɛna kɛ a dɔgɔyalenba ye siɲɛ 2 fo 4 ye, nɛgɛmafɛnw ni jibolisiraw ye minnu kogow ka fin, minnu kogow ka fin, ani jibolisiraw.
Tiɲɛ na, jibolisiraw sugandili min bɛ kɛ ni nɛgɛ ye, o tɛ dɔrɔn ni wari bilali daminɛ hakɛ dɔgɔman ye, nka a ka ɲɛnamaya kɛcogo musaka ka dɔgɔ kosɛbɛ fana. Nin ye sɔrɔko nafaba ye min bɛ sɔrɔ nɛgɛ intan na, fɛn wɛrɛw tɛ se ka bɛn min ma.
3. Kuma surun .
Pipu minnu bɛ kɛ ni nɛgɛ ye ani nɛgɛbere minnu bɛ kɛ ni nɛgɛ ye, olu fila bɛɛ ye jibolisiraw ye minnu ka ɲi kosɛbɛ. A ka ca a la, a ka teli ka kɛ ni nɛgɛberew ye i n’a fɔ jibolisiraw jamana kɔkan bawo, nɛgɛ sɔngɔ ka dɔgɔ jamana wɛrɛw la, wa jamana wɛrɛw ka yiriwali waati ka jan kosɛbɛ.
Ni jamana kɔnɔna na, nɛgɛdaga pipew yiriwali ye, sisan, diɲɛ tɔnba dɔ bɛ baara kɛ ni nɛgɛberew ye minnu bɛ kɛ ni nɛgɛ ye. Pipe inox application jigiya bɛna bonya dɔrɔn ani ka bonya don nataw la. Pipe dilannikɛlaw fanba ka kan ka baara kɛ . Precision inox tube dilanni masin teliya la ka sugu minɛ, ani . Hangao Tech (Seko Machinery) bɛna kɛ i ka jɛɲɔgɔn ye min bɛ se ka da a kan.
