Umthungo odityanisiweyo othe tye (ERW umthungo othe ngqo welding wentsimbi umbhobho) yenziwa kwipleyiti eshushu eqengqelekayo yomatshini wokwenza, isiphumo solusu kunye nefuthe lokusondela kwesantya esiphezulu sangoku, ukunyibilika komphetho wombhobho wokufudumeza kwi-extrusion roller pressure welding ukuphumeza imveliso.

Ukusetyenziswa kwendlela ye-welding ye-high-frequency resistance paveliso yombhobho ngeminyaka yee-1950s ibone itekhnoloji yokuvelisa eqolileyo ngakumbi kunye nokuphuculwa okuqhubekayo komgangatho wemveliso kule minyaka ilishumi idlulileyo okanye kunjalo.

Okokuqala, kumgangatho wezinto ezibonakalayo, ukuveliswa kwepayipi yensimbi ye-ERW kuye kwaphuculwa kakhulu, ukubunjwa koyilo lwensimbi yekhabhoni ephantsi, i-P ephantsi, i-S, i-micro-alloying; inkqubo yokunyibilikisa ukunyibilika, ukucocwa kweladle, ukucocwa kwe-vacuum, ukuphosa okuqhubekayo kunye nobunye ubuchwepheshe obutsha Ukongeza kwi-ERW elawulwayo yokuqengqeleka kunye nenkqubo yokuqengqeleka ebandayo, itekhnoloji yenze ukuba kubonakale ubungakanani bemichilo yentsimbi eshushu ephothiweyo yeetyhubhu zentsimbi ze-ERW ezinkulu neziphakathi. kuphuculwe kakhulu kumgangatho wenkangeleko, iipropathi zomzimba kunye neekhemikhali. Imibhobho yentsimbi eveliswe yiBaoshan Iron kunye neNkampani yeNsimbi, elona nqanaba liphezulu lentsimbi eshushu eqengqelekayo kwilizwe lam, idibene nomgangatho we-American Petroleum Institute API 5L kwaye ikwinqanaba eliphezulu lamazwe ngamazwe.

Ilandelwa ngumbindi kunye nobukhulu obukhulu ERW ukuwelda kunye nenkqubo yonyango ubushushu inkqubo yemveliso ukufikelela kwikhompyutha ulawulo oluzenzekelayo, frequency eliphezulu kunye nekhompyutha imbuyekezo oluzenzekelayo inkqubo ukuwelda inkqubo igalelo lobushushu amandla ilawulwa ngempumelelo ukuthintela ukuwelda igalelo ubushushu ukuwelda ukubanda okubangelwa low igalelo lobushushu be-welding kunye nokutshiswa okugqithisileyo okubangelwa ngamandla aphezulu. Ulawulo lobushushu bonyango lobushushu luvumela inkqubo yonyango lobushushu ukuba ifezekise ezona ziphumo zibalaseleyo ngokweemfuno zenkqubo, iqinisekisa ngokufanelekileyo umgangatho we-welding yentsimbi yombhobho wentsimbi kunye nommandla ochaphazelekileyo.

Ukongeza, inkqubela ye-ERW ityhubhu eqondileyo yokuhlola itekhnoloji yokuhlola umbhobho we-welded izuze i-intanethi epheleleyo okanye engaxhunyiwe kwi-intanethi ye-ultrasonic okanye i-eddy yangoku yomonakalo weld weld, kwaye uvavanyo loxinzelelo lwe-hydraulic lunokuba phantsi kweliso lekhompyutheni, uvavanyo loxinzelelo kunye neemfuno zokulawula. Ukukhuthazwa kunye nokuphunyezwa komgangatho kunye nokucaciswa kwe-APIQ1 ISO9000 series iqinisekisa ukuqinisekiswa komgangatho kuyo yonke inkqubo yokuvelisa, ukuhlolwa, ukuthengisa kunye nenkonzo ye-caliber ephakathi kunye nenkulu ye-ERW imibhobho yentsimbi yomthungo.

Kwiminyaka yakutshanje, amazwe ahlukeneyo athatha ngokukhutheleyo i-ERW yomthungo odityanisiweyo umbhobho kunye ne-spiral welded welded pipe endaweni, kumazwe ahambele phambili, i-ERW straight seam pipe diameter Ф610mm ngaphantsi, i-ERW yentsimbi yombhobho ifikelele malunga ne-70% yomlinganiselo. Umthamo wethu wemveliso we-ERW Longitudinal nawo uphuculwe.
