Umbhobho wensimbi kunye ne-welds ihanjiswa kwi-spiral ngokubhekiselele kwi-axis yomzimba wombhobho. Isetyenziswa kakhulu njengemibhobho yothutho, iimfumba zemibhobho, kunye neminye imibhobho yolwakhiwo. Iimpawu zemveliso: ububanzi obungaphandle 300 ~ 3660mm, ubukhulu bodonga 3.2 ~ 25.4mm.
Iimpawu zemveliso yombhobho we-spiral welded zezi:
(1) Imibhobho enobubanzi obahlukeneyo bangaphandle inokuveliswa kwimicu yobubanzi obufanayo;
(2) Umbhobho unobume obuhle kunye nemilinganiselo echanekileyo. I-welds ye-spiral yangaphakathi nangaphandle yokwandisa ukuqina komzimba wombhobho, ngoko akukho mfuneko yokulinganisa kunye neenkqubo zokulungelelanisa emva kwe-welding;
(3) Kulula ukuqonda umatshini, i-automation, kunye nemveliso eqhubekayo;
(4) Xa kuthelekiswa nezinye izixhobo zesikali esifanayo, inemilinganiselo emincinci, indawo encinci yokuhlala kunye notyalo-mali, kwaye iyakha ngokukhawuleza;
(5) Xa kuthelekiswa nemibhobho edityanisiweyo ethe tye yobukhulu obufanayo, i-weld seam ngeyunithi yobude bombhobho inde, ngoko ke imveliso iphantsi.

Inkqubo yemveliso yokuhamba kombhobho we-spiral welded:
Izinto eziluhlaza zemibhobho ye-spiral welded ziquka imicu kunye neepleyiti. Ipleyiti isetyenziswa xa ubukhulu bungaphezulu kwe-19mm. Xa usebenzisa ama-strips, ukuqinisekisa ukunikezelwa kwezinto eziqhubekayo ngexesha le-butt welding ye-coil yangaphambili nasemva, i-looper device ingasetyenziswa, okanye i-fly welding trolley ingasetyenziselwa ukudibanisa i-butt welding. Umsebenzi wonke wokulungisa izinto ukusuka ekukhululeni ukuya kwi-butt welding unokuqhutywa ecaleni kwendlela kwi-fly welding trolley. Igqitywe ngexesha lokuhamba. Xa umsila wentsimbi yangaphambili ubanjwe yintsimbi engasemva yomatshini wokuwelda i-butt, i-trolley itsalwa phambili ngesantya esifana nesokwenza kunye nomatshini wokuwelda kwangaphambili. Emva kokuba i-welding ye-butt igqityiwe, i-clamp yangasemva iyakhululwa kwaye i-trolley ibuyele ngokwayo. kwindawo yokuqala. Xa usebenzisa iipleyiti, iipleyiti zetsimbi enye kufuneka zifakwe kwi-butt-welded zibe yimichilo ngaphandle komgca wokusebenza, kwaye emva koko zithunyelwe kumgca wenkqubo yokusebenza ukuze zifakwe kwi-butt-welded kwaye zixhunywe kunye nemoto ye-welding endizayo. I-butt welding yenziwa kusetyenziswa i-arc ye-arc ezenzekelayo, eyenziwa kwindawo yangaphakathi yombhobho. Iindawo ezingangenwanga zenziwe kwaye zifakwe ngaphambili, kwaye emva koko zilungiswe kwindawo yangaphandle yombhobho, emva koko i-welds ye-spiral idityaniswe ngaphakathi nangaphandle. Ngaphambi kokuba umtya ungene kumatshini wokwenza, umphetho womcu kufuneka ugobe ngaphambili kwigophe elithile ngokusekwe kububanzi bombhobho, ubukhulu bodonga, kunye ne-angle yokubumba, ukuze i-deformation curvature yomphetho kunye nenxalenye ephakathi emva kokwenza. ehambelanayo nokuthintela isiphene "se-bamboo" seendawo ze-weld eziphumayo. Emva kokugoba kwangaphambili, ingena kwi-spiral yangaphambili yokwenza (jonga i-spiral forming) kunye ne-pre-welding. Ukuphucula imveliso, umgca wokubumba kunye ne-pre-welding uhlala usetyenziselwa ukufanisa imigca ye-welding yangaphakathi nangaphandle. Oku akunako nje ukuphucula umgangatho wee-welds kodwa ukwandisa kakhulu imveliso. Ukuwelda kwangaphambili ngokuqhelekileyo kusebenzisa i-welding ye-arc ekhuselekileyo yegesi okanye i-high-frequency resistance resistance welding kunye nesantya esikhawulezayo se-welding, kunye ne-welding epheleleyo. Le welding isebenzisa iipali ezininzi ezizenzekelayo ezintywilayo ze-arc welding.

Olona lwalathiso luphambili lophuhliso lwemveliso yombhobho we-spiral welded kungenxa yokuba uxinzelelo lwemibhobho luyanda imihla ngemihla, iimeko zokusetyenziswa ziya zisiba nzima, kwaye ubomi benkonzo yemibhobho kufuneka bandiswe kangangoko kunokwenzeka, ngoko ke imiyalelo yophuhliso ephambili imibhobho edityanisiweyo yile:
(1) Ukuvelisa imibhobho etyebileyo enobubanzi obukhulu obunodonga ukuze kuphuculwe ukumelana noxinzelelo;
(2) Yila kwaye uvelise imibhobho emitsha yentsimbi yolwakhiwo, enjengemibhobho edityanisiweyo ene-double-layer spiral, ethi idityaniswe ibe yimibhobho enomaleko-mbini kunye nentsimbi yomcu isiqingatha sobukhulu bodonga lombhobho. Akunjalo nje kuphela amandla abo aphezulu kunemibhobho ye-single-layer yobunzima obufanayo, kodwa abayi kubangela umonakalo onqabileyo;
(3) Ukuphuhlisa iintlobo ezintsha zentsimbi, ukuphucula umgangatho wobugcisa beenkqubo zokunyibilikisa, kunye nokwamkela ngokubanzi iinkqubo ezilawulwayo zokuqengqeleka kunye ne-post-rolling inkunkuma ukuze kuphuculwe ngokuqhubekayo amandla, ukuqina, kunye nokusebenza kwe-welding yomzimba wombhobho;
(4) Yenza imibhobho egqunywe ngamandla. Ngokomzekelo, ukugquma udonga lwangaphakathi lombhobho kunye ne-anti-corrosion layer ayikwazi nje ukwandisa ubomi benkonzo, kodwa kunye nokuphucula ukugudiswa kodonga lwangaphakathi, ukunciphisa ukuxhathisa kwe-friction, ukunciphisa i-wax kunye nokuqokelela kokungcola, ukunciphisa inani lombhobho. amaxesha okucoca, kunye nokunciphisa ukugcinwa.
