I n’a fɔ izini pibiliki nafama, nɛgɛ pipe, n’a jɔcogo kɛrɛnkɛrɛnnen ani a kɛcogo ɲuman, o kɛra baarakɛminɛn ye kosɛbɛ petoroli, kemikɛli, gazi nafama ani jɔli baarakɛyɔrɔw la. A jɔcogo kolomaw ani a ka nafa masinw b’a kɛ sugandili ɲuman ye waati jan-janya pipelines ani load-bearing structures.
1. Spiral Steel pipe ka fɛn jɔnjɔnw .
Spiral steel pipe ye nɛgɛ pipe weldalen ye min dilannen don ni nɛgɛ ye min bɛ kɛ ni nɛgɛ ye walima ni a bɛ kɛ ni bobine ye ka tɛmɛ spiral formation fɛɛrɛ fɛ. A jɔcogo jɔnjɔn ye fɛn saba ye: pipe farikolo, welda seam, ani kɔnɔna ni kɛnɛma furakɛli layiniw.
Pipe Body structure: Spiral steel pipe farikolo kunba bɛ dilan ni nɛgɛbere sɔgɔli ye ka taa a fɛ helikili kɛrɛnkɛrɛnnen dɔ la (a ka c’a la, degere 50 fo 70 na ). Nin sɛnɛcogo in bɛ kogo janya kelen ni jateminɛ hakɛ sabatilenw sabati, o bɛ se ka kɛ sababu ye ka pipe ka kɔnɔna tansiyɔnba muɲu.
welda seam structure: welda spiral steel pipe bɛ tilatila ni spiral pattern ye min bɛ to senna, o bɛ kɛ sababu ye ka weld seam janya ka tɛmɛ straight seam steel pipe kan. Nka, welding (sɔgɔli) kɛcogo bɛ baara kɛ ni fɛɛrɛ ɲumanw ye i n’a fɔ submerged arc welding (SAW) walima high-Frequency welding (HFW), o bɛ welda fanga ni density (dansi) caman sabati. Surface treatment: Ka da baarakɛyɔrɔ kan, spiral steel pipe surface bɛ se ka anti-corrosion treatment kɛ, i n’a fɔ epoxy powder coating, 3PE anti-corrosion layer, walima galvanizing, walasa k’a ka sɔgɔli kunbɛncogo n’a ka baara ɲɛnamaya sabati.
2. Nafa minnu bɛ sɔrɔ masinw na minnu bɛ wele ko spiral steel pipe .
Spiral Steel pipe jɔcogo bɛ masina jogo kɛrɛnkɛrɛnnenw di, o b’a to a bɛ kɛ fɛn ye min bɛ se ka kɛ sanfɛ-Pressure, belebele-Miayètre pipeline applications.
Fanga ni sabatili ka bon : K’a sababu kɛ spiral formation process ye, nɛgɛ pipe bɛ ni stress distribution kelen ye lamini ni axial sira fila bɛɛ la, minnu bɛ se ka muɲu kɔnɔna degunba ni kɛnɛma doniw kan. A ka hoop stress bearing seko bɛ tɛmɛ nɛgɛ pipe tilennen ta kan, o b’a to a bɛnnen don kosɛbɛ-pressure tulu ni gazi ta.
A bɛ se ka kɛ cogo min na, o bɛ se ka kɛ ka fɛnw labɛn: nɛgɛdaga min bɛ kɛ ni nɛgɛ ye, o dilanni bɛ sira di pipe belebelebaw dilanni ma-Miayètres diamètres bɛ se mɛtɛrɛ caman ma (misali la, DN3000 ani a sanfɛ), k’a sɔrɔ nɛgɛ pipe tilennen dan ye o siratigɛ la. O bɛ kɛ sababu ye ka spiral steel pipe kɛ fɛn ɲuman ye min bɛ kɛ ka ɲɛsin porozebaw ma minnu bɛ kɛ ni ji ye i n’a fɔ ji mara porozɛw ani ji jukɔrɔla pibilikiw. Welding reliability: modern spiral steel pipe welding techniques (i n’a fɔ double-Sided submerged arc welding) bɛ welda jogo ɲuman sabati. Ni a farala ɲɔgɔn kan ni non-i n’a fɔ X{10}}ray walima ultrasonic testing), o bɛ pibiliki lakanani sabati ka taa a fɛ.
3. Spiral Steel pipe baarakɛcogo .
Spiral Steel pipe jɔcogo b’a to a jɔyɔrɔ ka bon kosɛbɛ izini suguya caman na:
Tumu ni gazi tacogo: A bɛ kɛ ka jan-Yɔrɔjan tulu ni gazi bɔlanw na, a ka tansiyɔnba-Baari seko ni a sɔgɔli bɛ se ka kɛ sababu ye ka tulumafɛnw, gazi nafama, ani fɛn dilannenw ta ka taa ni u ye.
Ji maracogo ani minisiriso ka baara : I n’a fɔ jiko ni jibɔyɔrɔw, a cɛmancɛba bɛnnen don dugu jiko ni jibɔ siraw ma ani jibolisiraw sɛgɛsɛgɛlibaw-Scale.
Sow jɔcogo : nɛgɛ pipe bɛ se ka kɛ doni ye-bearing component in the pile fondements and supporting structures of bridges and high-rise buildings, o bɛ masinw dɛmɛ sabatilen di.
Kɔgɔjida la: Spiral Steel Pipe ni anti-Corosion furakɛli bɛ se ka kɛ ji jukɔrɔla pipelinew ni kɔgɔjida la plateformes kɔnɔ walasa ka kɔgɔji ji sɔgɔli ni a laminiw caya-pressure sigidaw la.
4. yiriwali nataw taabolo .
Ni ɲɛtaa bɛ fɛnw dɔnniya ni fɛn dilanni fɛɛrɛw la, Spiral Steel Pipe bɛ ka yiriwa ka taa fanga caman na, a girinya ka nɔgɔn, ani a sɔgɔli ka caya. Misali la, baara min bɛ kɛ ni High-Sɛnɛfɛn ye (i n’a fɔ API 5L X80 ani X100) ani finiko fɛɛrɛ kuraw (i n’a fɔ nano-Anti{6}}Corosion coatings) bɛ se k’a ka baara kɛcogo ɲɛ ka taa a fɛ. Ka fara o kan, welding automatique ani sɛgɛsɛgɛli fɛɛrɛ hakilitigiw tali bɛna kɛ sababu ye ka fɛn dilanni nafa n’a jogoɲini yiriwa.
Kuncɛli
Spiral steel pipe, n’a ka helical structure kɛrɛnkɛrɛnnen, a ka masina jogo ɲumanw, ani a ka baarakɛcogo caman bɛ se ka kɛ, o kɛra fɛn ye min nafa ka bon kosɛbɛ bi iziniw ni fɛnsɔrɔsiraw jɔli la. Don nataw la, ni fɛɛrɛ kuraw bɛ to sen na, nɛgɛso pipe bɛna a nafa jira yɔrɔ caman na, ka fura caman di diɲɛ fanga taabolo ni ɛntɛrinɛti jɔli ma.
