Umbhobho wentsimbi ngokuqhelekileyo wahlulwe kumbhobho wentsimbi ongenamthungo kunye nombhobho wentsimbi odityanisiweyo ngokweendlela zokuvelisa.Ngeli xesha ubukhulu becala sazisa umbhobho wentsimbi odityanisiweyo, oko kukuthi, umbhobho wentsimbi. ngeendlela ezahlukeneyo zokuwelda ukufumana umbhobho wentsimbi.
Xa kuthelekiswa nombhobho wentsimbi odityanisiweyo ongenamthungo, unemveliso echanekileyo eneempawu zokuchaneka okuphezulu, ngakumbi ubukhulu bodonga oluphezulu.izixhobo eziphambili ezilula, indawo yomgangatho omncinci, ukusebenza okuqhubekayo kwimveliso kunye nemveliso eguquguqukayo, umbhobho odityanisiweyo unokwahlulwa ube spiralUmbhobho odityanisiweyo we-arc ontywiliselweyo, umthungo othe tye onamacala amabini antywiliselwe iarc umbhobho odityanisiweyo kunye nombhobho odityanisiweyo wokuxhathisa.
1.Inkqubo yokuvelisa umbhobho wentsimbi ejikelezayo imi ngolu hlobo lulandelayo:
Iimathiriyeli ekrwada zombhobho wentsimbi ejikelezayo yi-strip coil, i-welding wire kunye ne-flux.zithuthwe phezu komhlaba, kwaye bent.Isixhobo solawulo gap weld isetyenziselwa ukuqinisekisa ukuba umsantsa weld uyahlangabezana neemfuno welding.Idayamitha yombhobho, ulungelelwaniso olungalunganga kunye nesithuba seweld zilawulwa ngokungqongqo.Emva kokusika kumbhobho wentsimbi enye yokuqala emithathu kwibhetshi nganye yemibhobho yentsimbi iphantsi kwenkqubo engqongqo yokuhlola kuqala, ukuze kujongwe iipropati zoomatshini, ukwakheka kweekhemikhali, imeko yokudibanisa kunye umgangatho womphezulu we-weld, kunye novavanyo olungonakalisi ukuqinisekisa ukuba inkqubo yokuvelisa umbhobho ifanelekile.inokufakwa ngokusesikweni kwimveliso.
2.LSAW umbhobho:
Ngokubanzi, umbhobho we-LSAW wenziwa ngepleyiti yentsimbi ngokusebenzisa iinkqubo ezahlukeneyo zokubumba, ezifana namacala amabini antywiliselwe kwi-arc welding kunye.ukwandisa emva kwe-welding.Iendlela zokwenza umbhobho we-LSAW ziquka i-uo (UOE), i-Rb (RBE), i-JCO (JCOE), njl.
Ukwenziwa kwenkqubo yombhobho we-UOE LSAW:
Inkqubo yokwenziwa kombhobho odityanisiweyo we-arc we-UOE longitudinal iquka ikakhulu iinkqubo ezintathu zokuyila: ukugoba kwepleyiti yentsimbi, ukwakheka kunye nokwakheka kwe-O.Inkqubo nganye isebenzisa ushicilelo olukhethekileyo lokubumba ukugqiba iinkqubo ezintathu zentsimbi yentsimbi edge ukugoba kwangaphambili, ukwenza ukwakheka kunye ne-O yokwenza ukuze kukhubaze ipleyiti yentsimbi ibe ityhubhu ejikelezayo. Inkqubo yokwenziwa kweJCOE longitudinal submerged arc welded pipe: in jc0 Emva koko. ukunyathela ngokuphindaphindiweyo kumatshini wokwenza, isiqingatha sokuqala sepleyiti yentsimbi sicinezelwa sibe kwimilo engu-J, size esinye isiqingatha sepleyiti yentsimbi sicinezelwe sibe ngu-J ukuze senze imilo engu-C.
Ukuthelekiswa kweJCO kunye neendlela zokubumba ze-uo:
Ukwakhiwa kwe-JCO kukwenza uxinzelelo oluqhubekayo., olutshintsha inkqubo yokwenza umbhobho wensimbi ukusuka kumanyathelo amabini e-UO ukwenza amanyathelo amaninzi.Kwinkqubo yokuqulunqa, i-plate yensimbi ine-deformation efanayo, uxinzelelo oluncinci olushiyekileyo kwaye akukho mkrwelo phezu komhlaba.Umbhobho wensimbi ocutshungulweyo unokuguquguquka okukhulu kuluhlu lobungakanani bobubanzi kunye nobukhulu bodonga.Inokuvelisa inani elikhulu leemveliso kunye neemveliso ezincinci.kunye neemveliso ezinkulu kunye nomgangatho ophezulu Isenokuvelisa ububanzi obuncinci kunye nemibhobho yentsimbi yodonga olukhulu.ingakumbi kwimveliso yomgangatho ophezulu wemibhobho eludongeni eshinyeneyo ingakumbi kwimveliso yemibhobho eludongeni engqindilili ephakathi kunye nencinci.Ineenzuzo ezingenakuqhathaniswa nezinye iinkqubo, kwaye inokuhlangabezana neemfuno ezininzi zabasebenzisi beenkcukacha zemibhobho yentsimbi.Ukubumba kwe-Uo kwamkela u kunye no-O-step-step pressure forming, ebonakaliswa ngumthamo omkhulu kunye nemveliso ephezulu. Ngokuqhelekileyo, imveliso yonyaka inokufikelela kwi-30 -30% 1 yezigidi zeetoni, zilungele imveliso enye yobuninzi.
3. Umbhobho odityanisiweyo othe nkqo
Umthungo othe tye we-welded welded pipe (ERW) wenziwa ngokufudumeza umda we-tube billet kunye nefuthe lolusu kunye nefuthe elisondele kwi-high frequency yangoku emva kokuba i-coil eshushu idityaniswe ngumatshini wokwenza, kwaye emva koko i-welding yoxinzelelo iyenziwa. phantsi kwesenzo se-roller extrusion.
