S355 ERW Pipe ea Tšepe Bakeng sa Meaho e boima ea Mosebetsi

Sebakeng sa kaho ea sejoale-joale le nts'etsopele ea meralo ea motheo, liphaephe tsa tšepe tsa S355 ERW (Electric Resistance Welded) li hlahile e le thepa ea bohlokoa, li fana ka matla a ikhethang, ho tenyetseha le ho tšepahala. Liphaephe tsena tsa tšepe tse sebetsang hantle li fetotse mekhoa ea kaho e boima, li fa baenjiniere le borakonteraka litharollo tse matla bakeng sa lits'ebetso tse fapaneng tsa meaho.

e sebetsa joang:

Meahong ea meaho, liphaephe tsa tšepe tsa S355 ERW li bonts'a ho feto-fetoha ho makatsang lits'ebetsong tse fapaneng. E le likarolo tsa mantlha meahong ea foreimi, liphaephe tsena li theha mokokotlo oa katleho e tsotehang ea meralo. Karolelano e phahameng ea matla ho boima ba lipeipi e etsa hore e be ea bohlokoa ka ho khetheha ha ho hahoa meaho e phahameng, moo e sebetsang e le litšiea tse otlolohileng le maballo a tšekaletseng, ho theha moralo o tiileng oa marapo o ka fihlang bophahamo ba limithara tse makholo a 'maloa.

Bakeng sa marokho, liphaephe tsa tšepe tsa S355 li bapala karolo ea bohlokoa mohahong o ka sehloohong oa tšehetso le likarolo tsa bobeli. Likarolo tsa tsona tse chitja kapa tse khutlonnetsepa li fana ka khanyetso e ntle khahlanong le matla a ho phethoha, e leng se etsang hore li be ntle bakeng sa li-girder tsa borokho le litšiea tsa tšehetso. Mehlala e hlahelletseng e kenyelletsa kaho ea marokho a khomaretsoeng ka cable, moo liphaephe tsena li etsang li-pylon tse ka sehloohong tse khomarelang likhoele tsa tšehetso.

Litsing tsa indasteri, haholo lifeme le matlong a polokelo, liphaephe tsa S355 li sebeletsa mesebetsi e mengata. Liphaephe li sebelisoa haholo lithupeng tsa marulelo, li nka sebaka se seholo ntle le litšehetso tse mahareng, kahoo li theha libaka tse pharaletseng, tse se nang litšiea tsa bohlokoa bakeng sa ts'ebetso ea tlhahiso. Kopo ea bona e atolohela ho meaho ea tšehetso ea li-conveyor, li-racks tsa liphaephe, le litšehetso tsa lisebelisoa, moo matla a bona a ho jara e leng a bohlokoa.

E le likarolo tse jarang moroalo, liphaephe tsena li bonts'a ts'ebetso e ikhethang tlasa maemo a fapaneng a khatello. Lits'ebetsong tsa marang-rang, karolo ea bona e ts'oanang e tiisa kabo e ts'oanang ea mojaro, athe tlhaho ea bona e sekoti e fana ka khanyetso e ntle haholo ha e sebelisoa e le litšiea. Ho feto-fetoha ha lipeipi ho lumella meralo ea boqapi ea truss, e nolofalletsang litsebi tsa meralo le lienjineri ho fihlela katleho ea sebopeho le boipiletso ba botle.

Meahong e koetsoeng, liphaephe tsa tšepe tsa S355 ERW li fumana lisebelisoa tse ncha. Li sebetsa e le likarolo tsa mantlha lits'ebetsong tsa facade, li fana ka tšehetso ea meralo le polelo ea meralo. Litabeng tsa terata le litšitiso tsa tšireletso, liphaephe tsena li fana ka nako e telele le matla ha li ntse li boloka ponahalo e hloekileng, ea setsebi. Tšebeliso ea tsona ho li-handrails le li-protein tsa tšireletso li kopanya ts'ebetso ea ts'ireletso le boipiletso bo botle.

Melemo ea Pipe ea tšepe ea S355 ERW Kahong e boima:

Litšobotsi tse matla tsa liphaephe tsa tšepe tsa S355 ERW li emela tsoelo-pele e kholo thepa ea kaho. Ka matla a fokolang a tlhahiso ea 355 MPa, liphaephe tsena li ka mamella meroalo e meholo ha li ntse li boloka botsitso ba sebopeho. Matla ana a makatsang a lumella baqapi ho totobatsa likarolo tse nyane ha li bapisoa le litšepe tsa maemo a tlase, e leng se fellang ka meaho e bobebe le litlhoko tse fokotsehileng tsa motheo. Thepa e tsitsitseng ea mechini ea liphaephe boleleleng bohle ba tsona e netefatsa ts'ebetso e tšepahalang tlas'a maemo a fapaneng a mojaro.

Ts'ebetso ea tjheseletso ea lipeipi tsa tšepe tsa S355 e hlahella e le molemo o moholo lits'ebetsong tsa kaho. Motsoako oa lik'hemik'hale oa thepa o laoloa ka hloko ho etsa bonnete ba hore o na le weldability e ntle haholo, e nang le litekanyetso tse lekanang tsa khabone tse thusang manonyeletso a matla, a tšepahalang. Mekhoa ea sejoale-joale ea ho tjheseletsa, ho kenyelletsa le shielded metal arc welding (SMAW) le gas metal arc welding (GMAW), e ka sebelisoa ka nepo setšeng, ho fokotsa nako ea kaho le litšenyehelo tsa mosebetsi.

Ho nepahala ha dimensional ho tlatsetsa haholo katlehong ea kaho. Ts'ebetso ea tlhahiso e netefatsa botenya ba marako bo tsitsitseng le litekanyo tse fapaneng, ka mamello e tloaelehileng ka har'a ± 1% ea boleng bo boletsoeng. Ho nepahala hona ho fokotsa tlhokahalo ea ts'ebetso e eketsehileng nakong ea kopano, ho fokotsa litšila tsa thepa, 'me ho netefatsa ho lekana hantle nakong ea kaho. Ho otloloha le ho pota-pota ha liphaephe tsena ho boetse ho thusa ho tsamaisana ha bonolo le ho hokahanya nakong ea ho kenya.

Ho ea ka pono ea moruo, liphaephe tsa tšepe tsa S355 li fana ka melemo e qobellang. Ho sa tsotellehe litšenyehelo tsa bona tsa pele tse phahameng ha li bapisoa le litšepe tsa boemo bo tlaase, matla a bona a phahameng a lumella ho fokotsa tšebeliso ea thepa, e lebisang ho bolokeng litšenyehelo ka kakaretso. Ho tšoarella ha lipeipi le litlhoko tsa tlhokomelo e tlase li kenya letsoho ho theoleng litšenyehelo tsa nako ea bophelo, ha ts'ebetso ea tsona e sebetsang hantle e fokotsa litšenyehelo tsa basebetsi le linako tsa projeke.

Litlhokomelo Bakeng sa Tšebeliso ea Pipe ea tšepe ea S355 ERW:

Kalafo ea holim'a metsi e bapala karolo ea bohlokoa ho netefatsa hore lipeipi tsa tšepe tsa S355 li phela nako e telele. Hot-dip galvanizing e fana ka ts'ireletso e ntle haholo ea kutu, ho theha lesela la zinki le kopantsoeng ka metallurgic ka botenya bo tloaelehileng ba 45-85 microns. Ts'ebetso ena e kenyelletsa ho qoelisa liphaephe ka zinki e qhibilihisitsoeng hoo e ka bang 450 ° C, e leng se etsang hore ho be le lera le tšoarellang la tšireletso. Mekhoa e meng ea phekolo ea holim'a metsi e kenyelletsa ho roala phofo, e fanang ka tšireletso ea kutu le ho feto-fetoha ha maemo, le mekhoa e khethehileng ea ho penta e etselitsoeng lisebelisoa tsa indasteri.

Ts'ebetso ea welding e hloka tlhokomelo e hlokolosi ho netefatsa boits'oaro ba sebopeho. Tokisetso e nepahetseng e kenyelletsa ho hloekisa sebaka se kopanetsoeng, ho boloka mocheso o loketseng oa preheat (hangata 100-150 ° C bakeng sa likarolo tse teteaneng), le ho khetha lisebelisoa tse loketseng tsa ho cheselletsa tse lumellanang le matla a tšepe ea motheo. Mehato ea taolo ea boleng nakong ea tjheseletsa e lokela ho kenyelletsa ho lekola mocheso o kenang lipakeng, ho boloka maemo a nepahetseng a ho kenya mocheso, le ho kenya tšebetsong kalafo e nepahetseng ea mocheso oa morao-rao ha ho hlokahala.

Liprothokholo tse felletseng tsa tlhahlobo le liteko li bohlokoa bakeng sa netefatso ea boleng. Tlhahlobo ea Ultrasonic (UT) e lemoha ka katleho liphoso tsa ka hare, e sebelisa maqhubu a molumo o phahameng haholo ho khetholla li-discontinuities ka har'a thepa. Teko ea radiographic (RT) e fana ka litšoantšo tse hlakileng tsa boleng ba weld ka tlhahlobo ea X-ray kapa gamma-ray. Mekhoa e meng e kenyelletsa tlhahlobo ea "magnetic particle inspection" (MPI) bakeng sa mefokolo e kaholimo le e haufi le bokaholimo, le tlhahlobo ea dae e kenang ka har'a dae bakeng sa ho khaotsa ho sebetsa.
