Imibhobho yentsimbi ngokuqhelekileyo yahlulahlulwe ibe yimibhobho yentsimbi engenamthungo kunye nemibhobho yentsimbi edityanisiweyo ngokwendlela yokuvelisa. Ngeli xesha ikakhulu sazisa imibhobho yentsimbi edityanisiweyo, oko kukuthi, imibhobho yentsimbi ethungelweyo. Imveliso kukugoba kunye nokuqengqeleka izikhala zemibhobho (iipleyiti zetsimbi kunye nemicu yentsimbi) kumacandelo afunekayo anqamlezayo ngeendlela ezahlukeneyo zokubumba. Xa kuthelekiswa nombhobho wentsimbi ongenamthungo odityanisiweyo, unomgangatho ophezulu wemveliso, ngokukodwa ukuchaneka kodonga oluphezulu, izixhobo ezilula ezingundoqo, unyawo oluncinci, Iimpawu zokusebenza okuqhubekayo kunye nemveliso eguquguqukayo kwimveliso, umbhobho odityanisiweyo kufuneka wahlulwe ngokwamacandelo amathathu: i-spiral ifakwe emanzini. Umbhobho odityanisiweyo we-arc, umthungo othe tye onamacala amabini antywiliselwe i-arc edityanisiweyo, kunye nomthungo othe tye odityanisiweyo wokumelana nombhobho odityanisiweyo.

1. Umbhobho odityanisiweyo we-arc odityanisiweyo

Izinto eziluhlaza zombhobho wensimbi ojikelezayo (i-SSAW) yi-strip coil, i-welding wire kunye ne-flux. Ngaphambi kokwenza, umtya uphantsi komgangatho, ukuchetywa komphetho, ukucwangciswa komphetho, ukucocwa komphezulu kunye nokuhanjiswa kunye nonyango lwangaphambili. Isixhobo sokulawula i-welding gap sisetyenziselwa ukuqinisekisa ukuba i-gap ye-welding ihlangabezana neemfuno ze-welding Kufuneka ukuba ulawule ngokungqongqo umda wombhobho, ukungahambi kakuhle kunye ne-weld gap. Emva kokusikwa kumbhobho omnye wentsimbi, imibhobho emithathu yokuqala yebhetshi nganye kufuneka ingene kwinkqubo engqongqo yokuhlola kuqala ukujonga iimpawu zomatshini, ukwakheka kweekhemikhali, imeko yokudibanisa kunye nomphezulu we-weld. Emva kokuhlolwa komgangatho kunye nokungonakalisi ukuqinisekisa ukuba inkqubo yokwenza umbhobho ifanelekile, inokufakwa ngokusemthethweni kwimveliso.

2. Umbhobho odityanisiweyo we-arc othe tye

Xa sithetha gabalala, umthungo othe tye wantywiliselwa we arc welded pipe (LSAW) yenziwe ngentsimbi yentsimbi. Emva kweenkqubo ezahlukeneyo zokwenza, umbhobho odibeneyo wenziwa ngokudibanisa i-arc edibeneyo kabini kunye nokwandiswa kwe-post-weld. Indlela yokwenza umthungo othe tye ofakwe emanzini we-arc welded pipe yi-UO (UOE). , RB (RBE), JCO (JCOE), njl.

UOE umthungo othe tye we arc odityanisiweyo wenkqubo yokwenza umbhobho:

Kukho ikakhulu ezintathu iinkqubo zokwenza kwi-UOE LSAW yokwenza umbhobho wensimbi: ipleyiti yensimbi yangaphambili yokugoba, i-U yokwenza kunye ne-O yokwenza. Inkqubo nganye isebenzisa umshicileli okhethekileyo wokubumba ukugqiba ukugoba kwangaphambili, u-U ukwenza kunye no-O ukwenza umda weplate yensimbi ngokulandelelana. Iinkqubo ezintathu, ipleyiti yentsimbi ikhubazeke ibe yityhubhu ejikelezayo, i-JCOE ethe tye umthungo entywiliselwe i-arc welded umbhobho wokwenza inkqubo: emva kokunyathela okuninzi kumatshini wokwenza i-JC0, isiqingatha sokuqala sepleyiti yentsimbi sicinezelwe kwimilo ye-J, kwaye ke enye isiqingatha sepleyiti yensimbi icinezelwe ibe yi-J shape shape, yenza i-C shape, igxininiswe ukusuka phakathi ukuya kwi-tube evulekile "O"-shaped tube blank.

Ukuthelekiswa kweJCO kunye neendlela zokubumba ze-UO:

Ukwakhiwa kwe-JCO kukwenza uxinzelelo oluqhubela phambili, olutshintsha inkqubo yokwenza umbhobho wensimbi ukusuka kumanyathelo amabini e-UO eyenza i-multi-step. Ngethuba lenkqubo yokuqulunqa, ipleyiti yensimbi ikhubazeke ngokufanayo, uxinzelelo olushiyekileyo luncinci, kwaye umphezulu awukhatywanga. Kukho ukuguquguquka okukhulu kubungakanani kunye noluhlu oluchaziweyo lobungakanani bodonga, olunokuvelisa zombini iimveliso ezinomthamo omkhulu kunye neemveliso zebhetshi ezincinci, kungekuphela nje imibhobho yentsimbi enobubanzi obukhulu obukhulu, kodwa kunye nemithanjana encinci enkulu- imibhobho yentsimbi ebiyelwe ngodonga, ngakumbi Ekuveliseni umgangatho ophezulu wemibhobho etyebileyo enodonga, ngakumbi ukuveliswa kwemibhobho engqindilili encinci naphakathi, ineengenelo ezingenakuthelekiswa nanto ngaphezu kwezinye iinkqubo, kwaye inokufikelela kwiimfuno ezininzi zabasebenzisi kwiinkcukacha zemibhobho yentsimbi. . Ukwenza i-UO yamkela i-U kunye ne-O yoxinzelelo oluphindwe kabini, olubonakala ngayo Inomthamo omkhulu kunye nemveliso ephezulu. Ngokubanzi, imveliso yonyaka inokufikelela kwi-300,000 ukuya kwi-1,000,000 yeetoni, ezilungele ukuveliswa kobuninzi benkcazo enye.

3. Umthungo othe nkqo umbhobho odityanisiweyo wokuxhathisa frequency

Umthungo othe tye umbhobho odityanisiweyo we-high-frequency high-frequency welded (ERW) wenziwa ngokusebenzisa isiphumo solusu kunye nefuthe elisondele kwi-high-frequency yangoku ukutshisa kunye nokunyibilika komphetho wetyhubhu engenanto emva kokuba i-coil eshushu iqhutywe ngumatshini wokwenza, kwaye emva koko. uxinzelelo-welding phantsi kwesenzo se-roller extrusion.
