Sekhahla se seholo sa Carbon Welded Spiral Steel Pipe

Tlhaloso e Khutšoanyane:

Spiral welded pipe: E entsoe ka tšepe e nang le khabone e tlase kapa ka tšepe e nang le alloy e tlase e phuthoa ka har'a billet ea phala ka lehlakoreng le itseng la spiral line (e bitsoang forming angle), ebe seame sa phala se kopanngoa hammoho, e ka hlahisa phala e kholo ea tšepe ea bophara ho tloha tšepe e moqotetsane.Litlhaloso tsa eona li hlahisoa ke bophara bo ka ntle * botenya ba lebota, phala e cheselitsoeng e lokela ho etsa bonnete ba hore tlhahlobo ea hydraulic, matla a thata a thepa ea weld le a batang a kobang ho kopana le lipehelo.

Liphaephe tse cheselitsoeng ka nako e telele tsa arc tse kentsoeng ka metsing li hlahisoa ka lipoleiti tsa tšepe, ha liphaephe tse cheselitsoeng ka spiral li hlahisoa ka likhoele tse kolobisitsoeng ka ho chesa.Hot-rolled hlobolisa yuniti rolara tshebetso na le palo ea melemo 'me o na le metallurgical tshebetso bokgoni ba ho fumana tlhahiso ea boleng bo phahameng phala line tšepe.Ka mohlala, ho ema ha tlhahiso ho na le tsamaiso ea ho futhumatsa metsi ho potlakisa ho pholile, e leng se lumellang tšebeliso ea lipina tse tlaase tsa alloy ho finyella limaraka tse khethehileng tsa matla le ho thata ha mocheso o tlaase, ka tsela eo ho ntlafatsa weldability ea tšepe.Leha ho le joalo, tsamaiso ena ha e eo haholo limela tsa tlhahiso ea letlapa la tšepe.Likahare tsa alloy (tse lekanang le k'habone) tsa li-coil hangata li tlase ho feta tsa lipalo tse tšoanang tsa lipoleiti tsa tšepe, tse ntlafatsang ho cheseha ha liphaephe tse cheselitsoeng ka spiral.

Habohlokoa le ho feta ke hore, hobane spiral welded pipe coil rolling direction is not perpendicular to direction of the iron pipe axis (tharollo ea eona ea pinch e itšetlehile ka angle ea spiral ea phala ea tšepe), ha karolo e otlolohileng ea seam e otlolohileng. tataiso perpendicular ho tataiso ea tšepe phala axis, 'me ka hona, spiral welded phala lintho tse bonahalang molemo ho feta ho otlolohile seam tšepe phala crack ho hanyetsa.

Mokhoa oa ho Welding

Ho tloha tshebetsong tjheseletsa, spiral welded phala le ho otloloha seam tšepe phala phala tjheseletsa mokhoa o tšoanang, empa seam otlolohileng tjheseletsa phala tla ke keng ea qojoa ba le e ngata ding tjheseletsa, kahoo menyetla ea ho tjheseletsa mefokolo e eketseha haholo, le khatello e setseng ea tjheseletsa. ha ding weld e kholoanyane, tšepe ea weld e atisa ho ba maemong a khatello ea maikutlo a mararo, ho eketsa monyetla oa ho phunyeha.

Ho feta moo, ho ea ka ts'ebetso ea ho tjheseletsa ka tlas'a metsi, e mong le e mong oa weld o lokela ho ba teng ha arc a qala le ho tima arc, empa e mong le e mong o otlolohileng oa seam welded pipe ka seam annular seam, a ke ke a finyella boemo, kahoo ho ka 'na ha e-ba le mefokolo e mengata ea tjheseletsa ho arc. ho tima.
