EFW piping ke eng?

Lefats'eng la lipeipi tsa indasteri, liphaephe tsa Electric Fusion Welded (EFW) li hlahile e le karolo ea bohlokoa, e fanang ka matla, ho tšepahala le ho feto-fetoha ha maemo ho pholletsa le mekhoa e fapaneng. Sengoliloeng sena se qaqisa lintho tse rarahaneng tsa EFW piping, ho hlahloba ts'ebetso ea eona ea tlhahiso, lits'ebetso tse tloaelehileng, le litekanyetso tse thata tse netefatsang boleng le ts'ebetso ea eona.

EFW (Motlakase Fusion Welded) Pipe Manufacturing

EFW piping, eo hape e tsejoang e le Electric Resistance Welded (ERW) piping, ke mofuta oa phala ea tšepe e entsoeng ka mokhoa o mocha oa ho tjheseletsa o sebelisang motlakase oa motlakase ho kopanya seam. Ts'ebetso ena e qala ka likhoele tsa tšepe tse bataletseng kapa li-coil, tse entsoeng ka hloko ho ba sebopeho sa cylindrical ebe li chesetsoa ho latela seam sa longitudinal.

Mokhoa oa ho etsa liphaephe tsa EFW o kenyelletsa mehato e 'maloa ea bohlokoa:

1. Tokisetso ea Li-Coil: Li-coil tsa boleng bo phahameng li khethoa le ho hloekisoa ka ho feletseng ho tlosa litšila leha e le life tse ka holim'a metsi.
2. Ho theha: Tšepe e feptjoa ka letoto la lirolara tse etsang butle-butle hore e be sebopeho sa tubular.
3. Welding: Ha likarolo tsa tube e entsoeng li kopana, ho sebelisoa motlakase oa maqhubu a phahameng, a hlahisang mocheso o kopanyang seam.
4. Ho pholisa le ho Siling: Peipi e cheselitsoeng e pholile ka potlako 'me e fetisetsoe meqolong ea boholo ho fihlela boholo bo lakatsehang.
5. Kalafo ea Mocheso: Ho itšetlehile ka kopo e reriloeng, phala e ka 'na ea fumana phekolo ea mocheso ho ntlafatsa thepa ea eona ea mochine.
6. Taolo ea Boleng: Mekhoa e matla ea tlhahlobo le tlhahlobo e kengoa ts'ebetsong ho netefatsa hore phala e kopana le maemo a indasteri.

Mokhoa ona o sebetsang oa tlhahiso o lumella ho hlahisa liphaephe tsa EFW ka boholo bo sa tšoaneng, ka tloaelo ho tloha ho 8 ho ea ho lisenthimithara tse 24 ka bophara, ka bophara ba marako ho fihlela ho 0.5 inches. Ts'ebetso e laoloang ea tjheseletsa e fella ka seam se matla, se ts'oanang seo hangata se ke keng sa khetholloa ho tloha leboteng la liphaephe.

E 'ngoe ea melemo ea bohlokoa ea liphaephe tsa EFW ke ho sebetsa hantle ha eona ha ho bapisoa le liphaephe tse se nang moeli, haholo-holo bakeng sa lisebelisoa tse kholo tsa bophara. Ts'ebetso e tsoelang pele ea tlhahiso e boetse e lumella hore ho be le lebelo le phahameng la tlhahiso, ho kenya letsoho ho eketsa tlhahiso le linako tse khutšoanyane tsa ho etella pele.

Likopo tse Tloaelehileng tsa EFW Piping ho indasteri

Ho feto-fetoha ha maemo le ho ts'epahala ha liphaephe tsa EFW ho lebisitse ho amoheloeng ha eona hohle liindastering tse ngata. Tse ling tsa lisebelisoa tse tsebahalang haholo li kenyelletsa:

1. Lipalangoang tsa Oli le Khase: Lipeipi tsa EFW li sebelisoa haholo ha ho etsoa liphaephe bakeng sa ho tsamaisa oli e tala, khase ea tlhaho le lihlahisoa tse hloekisitsoeng tsa petroleum libakeng tse telele.
2. Kabo ea Metsi: Litsamaiso tsa phepelo ea metsi tsa masepala hangata li sebelisa liphaephe tsa EFW bakeng sa ho tšoarella ha tsona le ho hanyetsa ho bola ha li koahetsoe hantle.
3. Kaho: Ka indasteri ea kaho, liphaephe tsa EFW li sebelisetsoa merero ea meralo, joalo ka liqubu le tšehetso ea motheo.
4. Liphaephe tsa Tsamaiso ea Liindasteri: Mehaho e mengata ea tlhahiso e itšetlehile ka liphaephe tsa EFW bakeng sa ho tsamaisa maro le likhase tse fapa-fapaneng mekhoeng ea tsona ea tlhahiso.
5. Indasteri ea Likoloi: Liphaephe tsa EFW li fumana lits'ebetso lits'ebetsong tsa mosi le likarolo tsa sebopeho sa makoloi.
6. Temo: Mekhoa ea ho nosetsa le lisebelisoa tsa polasi hangata li kenyelletsa liphaephe tsa EFW bakeng sa matla a eona le katleho ea eona.

Mefuta e mengata e fapaneng ea likopo tsa EFW piping ke bopaki ba ho feto-fetoha ha eona le ho tšepahala. Bokhoni ba eona ba ho mamella likhatello tse phahameng le mocheso, hammoho le khanyetso e ntle ea kutu ha e phekoloa hantle, e e etsa khetho e nepahetseng bakeng sa merero e mengata ea indasteri le ea meaho.

Matla le Maemo a Teko bakeng sa Liphaephe tsa EFW

Ho netefatsa boleng le ts'ebetso ea liphaephe tsa EFW, bahlahisi ba khomarela litekanyetso tse thata tsa indasteri le ho etsa mekhoa e matla ea tlhahlobo. Litekanyetso tsena hangata li akaretsa likarolo tse joalo ka sebopeho sa thepa, mamello ea boholo, thepa ea mochini, le bots'epehi ba weld.

E meng ea litekanyetso tsa bohlokoa tse laolang tlhahiso le tlhahlobo ea liphaephe tsa EFW li kenyelletsa:

• API 5L: Tlhaloso bakeng sa Pipe ea Line
• ASTM A53: Tlhaloso e Tloaelehileng bakeng sa Pipe, tšepe, e Ntšo le e Chesang, e koahetsoeng ka Zinc, e Welded ebile ha e Seamless
• ASTM A135: Tlhaloso e Tloaelehileng ea Motlakase-Resistance-Welded Steel Pipe
• EN 10217: Li-tubes tsa tšepe tse cheselitsoeng molemong oa khatello

Mekhoa ea tlhahlobo ea liphaephe tsa EFW e pharalletse ebile e ka kenyelletsa:

1. Teko ea Hydrostatic: Liphaephe li hatelloa ka metsi ho netefatsa bokhoni ba tsona ba ho mamella khatello ea ts'ebetso ntle le ho lutla.
2. Teko e sa Senyeheng (NDT): Mekhoa e joalo ka tlhahlobo ea ultrasonic, tlhahlobo ea hajoale ea eddy, le tlhahlobo ea likaroloana tsa makenete li sebelisoa ho bona mefokolo efe kapa efe leboteng la phala kapa seam sa weld.
3. Teko ea Mechini: lisampole li etsa liteko tse matla, matla a tlhahiso, le liteko tsa bolelele ho netefatsa hore li kopana le thepa e boletsoeng ea mochini.
4. Tlhahlobo ea Lik'hemik'hale: Sebopeho sa tšepe se netefatsoa ho netefatsa hore se kopana le litlhaloso tse hlokahalang.
5. Tlhahlobo ea Dimensional: Liphaephe li lekantsoe ho netefatsa hore li kopana le bophara bo boletsoeng, botenya ba lebota, le mamello e otlolohileng.

Mekhoa ena e matla ea tlhahlobo e netefatsa hore liphaephe tsa EFW li kopana kapa li feta matla le litlhoko tsa boleng bakeng sa lits'ebetso tse reriloeng. Motsoako oa mekhoa e tsoetseng pele ea tlhahiso le mehato e thata ea taolo ea boleng e fella ka liphaephe tsa EFW tse fanang ka ts'ebetso e ntle haholo le ho ts'epahala maemong a mangata a indasteri.

Mabapi le Sehlopha sa Longma

Pipe ea EFW e itlhomme e le karolo ea bohlokoa liindastering tse ngata, e fanang ka tekanyo ea matla, ho feto-fetoha ha maemo, le ho boloka litšenyehelo. Ho tloha ho lipalangoang tsa oli le khase ho ea kabong ea metsi le lits'ebetsong tsa indasteri, liphaephe tsa EFW li tsoela pele ho bapala karolo ea bohlokoa meahong ea sejoale-joale le tlhahisong.

Ha tsoelo-pele ea theknoloji le litlhoko tsa indasteri li fetoha, baetsi ba liphaephe tsa EFW ba tsoela pele ho ntlafatsa lits'ebetso le lihlahisoa tsa bona ho fihlela litlhoko tse ntseng li eketseha tsa makala a fapaneng. Litekanyetso tse thata le mekhoa ea liteko li netefatsa hore liphaephe tsa EFW li boloka boleng ba tsona bo phahameng le ho tšepahala, ho etsa hore e be khetho e ratoang bakeng sa likopo tse ngata.
