Ka tugu yiriwali teliya la, n’o ye strip continuous rolling production ɲuman ye ani kuran welding ni testing technology yiriwali, welding quality ɲɛtaa sabatili, 316L inoxydable industriel welded pipes suguya fana bɛ ka caya, wa a ye stainless nɛgɛ bila a nɔ na izini caman kɔnɔ. Aw bɛ tubabufura siri. Pipew weldalenw dilanni taabolo la, a bɛ se ka fɔ ko welda fanga bonya ye gɛlɛya ye min ka bon kosɛbɛ.
316L inox industrial welded pipe in inox bɛ farati dogolen caman na, i n’a fɔ nin cogo la:
(1) Degun sɔgɔli ka bɔ welda la .
Butt joint ka degun kunba bɛ sɔrɔ welding janya fɛ, ani in-situ stress at the welda toe of the butt joint ka bon kosɛbɛ.
Stress index hakɛw ye welda janya H ye, a cɛmancɛ θ bɛ welda senkɔni na ani nkɔni semi-warp r. welding janya H ka caya bɛ dɔ fara angle θ kan, wa nafa dɔgɔyali bɛna dɔ fara degun index kan.
Ni welda barika bonya ka bon, degun hakɛ ka jugu, nka butt welding fanga bɛ dɔgɔya. welding kɔfɛ, aw bɛ a janya tɛmɛnen kɛ fla ye, ni a ka bon ni butt welda ye, aw bɛ degunw dɔgɔya. Tuma dɔw la, a bɛ se ka dɔ fara butt welding fanga kan. Kɛnɛma welda bɛ ni janya tolenba ye, o bɛna kɛ sababu ye ka tubabufura cogoya bila farati la degun bonya kɔfɛ.
Ni pipe weldalen tilennen bɛ bonya degun kɔnɔ, nɛgɛ pipe min tɛ fɛn tiɲɛ, o bɛ siri ka kɛɲɛ ni kɛnɛma-molɔli yɔrɔ fila ye minnu bɛ kɛ numan fɛ ani numan fɛ ni kɔnɔna kogo kelen ye ani nɛgɛ pipew ka bonyacogo ɲɛfɔcogo si tɛ yen. O la, ni welda barika bonya ka bon kojugu, ni a cɛmancɛ bɛ bonya, shear stress min bɛ miiri welda fɛ o ka teli ka 'small straight edges' welda belebele fan fila bɛɛ la.
Nka, baara kɛcogo y’a jira ko ni kɛnɛma welda fanga bonya bɛ 2mm walima a dɔgɔyalen na, a man nɔgɔn ka 'small straight edges' sɔrɔ ni degun bɛ bonya. Pipe suguya man nɔgɔn ka tiɲɛni kɛ. O bɛ kɛ bawo kɛnɛma welda barika ka dɔgɔ, wa sɛgɛn min bɛ sɔrɔ butt welda fɛ, o fana ka dɔgɔ. Ni nin sɛgɛn suguya in bɛ ductile deformation (ductile deformation) hakɛ la, a jiginlen kɔfɛ, resilience (dafalen) bɛ sɔrɔ, ani ji pipe (jibɔlan) bɛ segin a cogo kɔrɔ la.
(2) Kɔnɔnatumuw sɔgɔli janya tolenba bɛ yen, o bɛ dɔ fara bolifɛnw fanga ni fanga tiɲɛni kan.
Ni arc welded pipe kɛnɛma yɔrɔ tɛ datugu ni anti-corrosion solution ye, welding seam janya tolenba bɛ a la, wa frictionnel resistance to the transport material fana ka bon, o bɛna dɔ fara bolifɛn pipeline fanga kan.
(3) kɛnɛma sɔgɔli janya ka bon, o man ɲi walasa ka nɔgɔ bali.
Ni epoxy resin laminated glass fini bɛ kɛ ka anti-corrosion kɛ baara kɛtuma na, kɛnɛma welda seam janya wɛrɛ bɛna a to a ka gɛlɛn ka digi kosɛbɛ welda senkɔni na. Ka fara o kan, ni welding seam ka bon ani ni anti-corrosion layer ka kan ka bonya ka taa a fɛ, o la, anti-corrosion layer standard ka bonya bɛ jate ka da welda sɔgɔli laban kan, o min bɛ dɔ fara corrosion anti-corrosion musaka kan.
ni a bɛ tali kɛ kɔnɔna scraper suguya kɔnɔna na welda bɔli minɛnw na, . Hangao Tech (Seko Masina) ka . Fiɲɛ bɛ don kɔnɔna na ni welda ye min bɛ kɛ ni fiɲɛ ye, o bɛ kɛ ni sɔgɔsɔgɔninjɛ ye min bɛ kɛ ni nɛgɛ ye min bɛ kɛ ni nɛgɛ ye. A ka baarakɛcogo ye ka baara kɛ ni mandrɛli ye min bɛ don a kɔnɔ walasa ka jɛɲɔgɔnya kɛ ni rolling die ye walasa ka segin-ka-bɔ siɲɛ 30/min kɔnɔna welda seam kan, walasa welda seam ni basi nɛgɛ ka don ɲɔgɔn na kosɛbɛ ani degun bɛ dɔgɔya.
Ni o gɛlɛya suguw bɛ aw la, aw bɛ se ka lajɛ kɛ. An nisɔndiyalen don kosɛbɛ ka jaabi di aw ma.
