ERW Pipe's litebello tsa nts'etsopele le mathata a tobaneng

Resistance welding e khuts'oane le phala ea tšepe ea ERW e nang le melemo e mengata, joalo ka tlhahiso e phahameng, litšenyehelo tse tlase, ho nepahala ha sebopeho, ponahalo e ntle.Leha ho le joalo, nakong e fetileng, ka lebaka la ts'epahalo e futsanehileng ea weld, mefokolo e kholo ea tšebeliso.Karolo ea tlhahiso ea liphaephe tse nyane.

Mochini oa welding oa tšepe oa ERW o entse katleho e khahlisang, 'me khopolo ena e le tataiso ea ho ntlafatsa.Theknoloji ea taolo ea othomathike ea ho ntlafatsa liparamente tse fanoeng ho netefatsa hore boleng ba weld bo ntlafala haholo;ka lebaka la ntlafatso ea theknoloji ea ho lemoha ultrasonic, ultrasonic flaw detector Wong stack track track e ka finyelloa moleng oa tlhahiso;ka lebaka la ntlafatso ea boemo ba ho iketsetsa.The annealing ea weld (normalizing) mohato oa phekolo moleng oa tlhahiso.Ntlafatso ea ts'ebetso ea weld.

Ka holim'a lits'ebetso tse 'maloa tsa tekheniki, e ntlafalitse haholo ho ts'epahala ha lipeipi tsa tšepe tsa ERW.Ho etsa hore ho be le mefuta e mengata e fapaneng ea lisebelisoa.Hona joale, tse ling tsa tlhahiso ea lefats'e ea ERW steel pipe pipe plant e ka sebelisoa libakeng tse batang, 'me linaha tse ngata li ntse li haha ​​​​mohala oa tlhahiso ea lipeipi tsa ERW.

Ho tsoa linaheng tsa tlhahiso ea liphaephe tsa ERW, ho phaella ho tlhahiso e phahameng ea pejana, e tlaase ho ea ho buuoa, ho nepahala ha dimensional ho tsoa ka ntle, matla a thata a tjheseletsa.Elongation off le shrinkage, teko ea ho khumama mocheso oa mocheso oa mocheso oa mocheso oa mocheso o ka finyella litlhoko tse boletsoeng.Empa ho na le bahlahisi ba bangata ba ERW steel pipe welds futsanehile mocheso o tlase, o fokotsang tšebeliso ea bona libakeng tse batang.
