ERW (Electric Resistance Welded) imibhobhoziveliswa kwiikhoyili ezishushu ezisongiweyo ngokudibanisa ngombane iziphelo zombini zekhoyili.I-high-frequency current idluliswa kwiikhoyili eziqengqelekayo zisebenzisa i-electrode zethusi.
Ukuchasana kombane phakathi kwabaqhubi kubangela ukushisa okukhulu ukuba kugxininise emaphethelweni, kudala ukuxhathisa.Emva kokuba ubushushu obuthile bufikelelwe, uxinzelelo lufakwa, lubangela ukuba i-seams ihlangane.
Iimpawu ze-ERW Imibhobho:
● Umthungo odityanisiweyo welongitudinal.
● Yenziwe ngokudlula i-high-frequency current ngokusebenzisa iikhoyili zetsimbi kunye nokudibanisa iziphelo phantsi koxinzelelo oluphezulu.
● Idayamitha yangaphandle iqala kwi-½ ukuya kwi-intshi ezingama-24.
● Ubukhulu bodonga buhluka ukusuka kwi-1.65 ukuya kwi-20mm.
● Ubude obuqhelekileyo yi-3 ukuya kwi-12 m, kodwa ubude obude buyafumaneka xa uceliwe.
●Inokuba neziphelo ezicacileyo, ezithundeziweyo, okanye ezibeveled njengoko kuchaziwe ngumxhasi.
● Imibhobho ye-ERW echazwe phantsi kwe-ASTM A53 yenza isiseko semibhobho emininzi esetyenziswa kwi-oyile, kwirhasi, okanye kulwelo lomphunga.
Inkqubo Yokwenziwa Kwemibhobho ye-ERW:
● Iikhoyili zentsimbi zizinto ezisisiseko zokwenza imibhobho ye-ERW.
● Imicu yentsimbi iyacandwa ibe ngobubanzi nobukhulu obuthile ngaphambi kokuba ifakwe kwiindawo zokusila.
● Iikhoyili zentsimbi ziyakhutshwa kumnyango wesixhobo sokusila i-ERW zize zidluliselwe kwindawo yokusila ukuze zenze imilo efana netyhubhu enomthungo welongitudinal ongavalwanga.
● Kusetyenziswa iindlela ezahlukahlukeneyo ezifana ne-seam welding, i-flash welding, ne-resistance projection welding.
● I-high-frequency, i-low-voltage yombane igqithiswa ngee-electrode zethusi ezibamba kumbhobho wentsimbi ongagqitywanga ukutshisa imiphetho evulekileyo.
● I-Flash welding idla ngokusetyenziswa njengoko ingadingi mpahla yokuthambisa.
● Iifom zokukhupha i-arc phakathi kwemiphetho, kwaye ekufikeleleni kwiqondo lokushisa elichanekileyo, i-seams ixinzelelwe kunye ukuze idibanise imveliso.
● Amaso e-welding ngamanye amaxesha anqunywe kusetyenziswa izixhobo ze-carbide, kwaye iindawo ezidibeneyo zivumelekile ukuba zipholile.
● Iityhubhu epholileyo inokungena kuluhlu lokulinganisa ukuqinisekisa ukuba idiameter yangaphandle iyahlangabezana nemilinganiselo.
Imibhobho yentsimbi eGalvanized
Usetyenziso lweMibhobho ye-ERW:
● Eyona mibhobho ye-ERW isetyenziswa njengemibhobho yokuthwala ioli ekrwada, igesi yendalo, kunye nezinye izinto.Zinomlinganiselo ophezulu we-diameter kunemibhobho engenamthungo kwaye zinokuhlangabezana neemfuno eziphezulu kunye neziphantsi zoxinzelelo, okwenza zibe luncedo njengemibhobho yokuthutha.
● Imibhobho ye-ERW, ngokukodwa ye-specification API 5CT, isetyenziswa kwi-casing kunye ne-tubing
● Imibhobho ye-ERW isenokusetyenziswa njengeityhubhu ezilungelelanisiweyo zezityalo zamandla omoya
● Imibhobho ye-ERW isetyenziswa kushishino lwemveliso njengokuthwala imikhono, ukusetyenzwa koomatshini, umatshini wokulungisa, kunye nokunye
● Ukusetyenziswa kombhobho we-ERW kubandakanya ukuhanjiswa kwerhasi, umbhobho wolwelo lombane wombane, nokunye.
● Bakwanazo nezinto zokwakha, imibhobho engaphantsi komhlaba, uthutho lwamanzi kumanzi aphantsi komhlaba, kunye nokuthutha amanzi ashushu.
