Liyini ipayipi lensimbi le-ERW? Umehluko omkhulu phakathi kwepayipi lensimbi ye-ERW (Electric Resistance Welding, efushanisiwe ngokuthi ERW) kanye nepayipi lensimbi engenamthungo ukuthi i-ERW inomthungo wokushisela, okuphinde kube ukhiye wekhwalithi yepayipi lensimbi le-ERW. Ubuchwepheshe besimanje bokukhiqiza ipayipi lensimbi le-ERW kanye nemishini, ngenxa yamazwe ngamazwe Ikakhulukazi ngemizamo engapheli ye-United States namanye amazwe phakathi neminyaka edlule, ukungabi namthungo kwamapayipi ensimbi e-ERW kuye kwaxazululwa ngendlela egculisayo. Abanye abantu bahlukanisa ukungabi mthungo kwamapayipi ensimbi e-ERW abe ukuthungwa kwejiyomethri kanye nokungabi mthungo ngokomzimba. Ukungenamthungo kweJiyomethri kusho ukusula amapayipi ensimbi e-ERW. Ama-burrs angaphakathi nangaphandle. Ngenxa yokuthuthukiswa okuqhubekayo kanye nokuthuthukiswa kwesakhiwo sesistimu yokukhipha i-burr yangaphakathi kanye namathuluzi okusika, ama-burrs angaphakathi amapayipi ensimbi amakhulu naphakathi nendawo asetshenzwe kangcono. Ama-burrs angaphakathi angalawulwa cishe -0.2mm~+O.5mm futhi akhululekile ngokomzimba. I-Seamization isho umehluko phakathi kwesakhiwo se-metallographic ngaphakathi kwe-weld kanye nesisekelo sensimbi, okuholela ekwehleni kwezakhiwo zemishini zendawo yokushisela. Kudingeka kuthathwe izinyathelo ukuze kufane futhi kuhambisane. Inqubo yokushisela ye-high-frequency welding yamapayipi ensimbi e-ERW ibangela ukuba ishubhu lingabi nalutho I-gradient yokusabalalisa izinga lokushisa eduze konqenqema yakha indawo encibilikisiwe, indawo encibilike kancane, isakhiwo esishisa kakhulu, indawo evamile, indawo yokujwayela engaphelele, indawo yokufudumala. , ezinye izindawo zesici. Phakathi kwazo, ukwakheka kwendawo eshisa kakhulu yi-austenite ngenxa yokushisa kwe-welding ngaphezu kwe-1000 ° C. Izinhlamvu zikhula ngokushesha, futhi isigaba sekristalu esiqinile nesiphukayo sizokwakhiwa ngaphansi kwezimo zokupholisa. Ngaphezu kwalokho, ukuba khona kwezinga lokushisa kuzodala ingcindezi yokushisela. Lokhu kubangela isimo lapho izakhiwo zemishini yendawo ye-weld ziphansi kunalezo eziyisisekelo kanye nokungabi namandla ngokomzimba kufinyelelwa. Kungenqubo yendawo yokwelapha ukushisa okuvamile komthungo we-weld, okungukuthi, kusetshenziswa idivayisi yokushisa yokungenisa imvamisa emaphakathi ukushisa indawo ye-weld seam ibe yi-AC3 (927°C), bese kwenziwa inqubo yokupholisa komoya enobude obungama-60m. kanye nesivinini esingu-20m/min, bese kuba nokupholisa amanzi uma kunesidingo. Ukusetshenziswa kwale ndlela kungafinyelela ukuqeda ukucindezeleka, ukuthambisa nokucwenga isakhiwo, futhi kuthuthukiswe izakhiwo ezibanzi zemishini yendawo ethinteke ukushisa okushisela, okwamanje, amayunithi e-ERW athuthukisiwe emhlabeni ngokuvamile amukele le ndlela yokucubungula ama-welds, futhi azuzile. imiphumela emihle. Ikhwalithi ephezulu yamapayipi ensimbi ye-ERW awawona kuphela I-weld seam engakwazi ukukhonjwa, futhi i-coefficient ye-weld seam ifinyelela ku-1, ifinyelela ukufana phakathi kwesakhiwo sendawo ye-weld kanye nezinto eziyisisekelo. Amapayipi ensimbi e-ERW anenzuzo yokusebenzisa amakhoyili agoqelwe ashisayo njengezinto ezingavuthiwe, futhi ukujiya kodonga kungalawulwa ngokufanayo kucishe kube ngu-±0.2mm. Iziphetho ezimbili zepayipi lensimbi Ngokusho kwezinga le-American APl noma i-GB/T9711.1 ejwayelekile, inezinzuzo zokuphela kwe-beveling nokulethwa kobude obungaguquki. Eminyakeni yamuva, amaphrojekthi enethiwekhi yamapayipi egesi emvelo ahlukahlukene kanye nezinkampani zegesi zamukele kabanzi amapayipi ensimbi e-ERW njengamapayipi ensimbi ayinhloko kumanethiwekhi amapayipi asemadolobheni.
