Umbhobho ojikelezayongumbhobho wentsimbi yomthungo ojikelezayo owenziwe nge-coil yentsimbi njengento ekrwada, ekhutshiweyo kwiqondo lobushushu eliqhelekileyo, kwaye idityaniswe yinkqubo yokuwelda i-arc ezenzekelayo emacaleni amabini. Umbhobho wentsimbi ojikelezayo wondla umcu wentsimbi kwiyunithi yombhobho odityanisiweyo. Emva kokuqengqeleka ngama-roller amaninzi, i-strip iron iqengqeleka ngokuthe ngcembe ukuze yenze i-billet yetyhubhu ejikelezayo ene-gap yokuvula. Lungisa ukucuthwa kwe-extrusion roller ukulawula i-gap ye-weld seam kwi-1 ~ 3mm kwaye wenze iziphelo ezimbini ze-weld joint egungxulwayo.

Imathiriyeli yombhobho weSpiral:
Q235A, Q235B, 10#, 20#, Q345 (16Mn),
L245(B), L290(X42), L320(X46), L360(X52), L390(X56), L415(X60), L450(X65), L485(X70), L555(X80)

L290NB/MB(X42N/M), L360NB/MB(X52N/M), L390NB/MB(X56N/M), L415NB/MB(X60N/M), L450MB(X65), L485MB(X70), L555MB(X80) .

Inkqubo yokuvelisa umbhobho ojikelezayo:

(1) Imathiriyeli ekrwada zizikhoyili zentsimbi, iingcingo zokuwelda, kunye ne-fluxes. Ngaphambi kokuba zisetyenziswe, kufuneka zidlule kuvavanyo olungqongqo lomzimba kunye neekhemikhali.
(2) I-head-to-tail butt joint ye-strip yentsimbi ithatha i-arc-wire okanye i-double-wire submerged arc welding, kunye ne-arc welding ezenzekelayo ephantsi kwamanzi isetyenziselwa ukulungiswa kwe-welding emva kokuqengqeleka kwimibhobho yentsimbi.
(3) Ngaphambi kokuqulunqwa, intsimbi ye-strip ihlanjululwa, inqunywe, icwangciswe, icociwe, ihanjiswe kwaye igobe ngaphambili.
(4) Iigeyiji zoxinzelelo lombane zisetyenziselwa ukulawula uxinzelelo lweesilinda kumacala omabini omqhubi ukuqinisekisa ukuhanjiswa okugudileyo komcu.
(5) Ukwamkela ulawulo lwangaphandle okanye ukwenziwa koluhlu lolawulo lwangaphakathi.
(6) Isixhobo sokulawula i-weld gap sisetyenziselwa ukuqinisekisa ukuba i-gap ye-weld ihlangabezana neemfuno ze-welding, kunye nobubanzi bombhobho, ukungahambi kakuhle kunye ne-weld gap ilawulwa ngokungqongqo.
(7) Zombini i-welding yangaphakathi kunye ne-welding yangaphandle zisebenzisa i-American Lincoln welding machine kwi-welding-wire okanye i-double-wire submerged arc welding, ukuze kufumaneke umgangatho ozinzileyo we-welding.
(8) Zonke i-welded seams zihlolwe yi-intanethi eqhubekayo ye-ultrasonic i-flaw detector ezenzekelayo, eqinisekisa i-100% yovavanyo olungonakalisi ukugubungela i-spiral welds. Ukuba kukho isiphene, kuya ngokuzenzekelayo i-alamu kwaye itshize uphawu, kwaye abasebenzi bemveliso banokuhlengahlengisa iiparitha zenkqubo nangaliphi na ixesha ngokutsho oku ukuphelisa isiphene ngexesha.
(9) Sebenzisa umatshini wokusika iplasma yomoya ukusika umbhobho wentsimbi ube ngamaqhekeza omnye.
10 inkqubo yokwenza umbhobho ufanelekile phambi kokuba ubekwe ngokusesikweni kwimveliso.
(11) Amalungu aphawulwe ngokufunyaniswa kwempazamo ye-ultrasonic kwi-weld iya kuphinda ihlolwe i-ultrasonic manual kunye ne-X-ray. Ukuba ngokwenene kukho iziphene, emva kokulungiswa, ziya kuphinda zihlolwe ngokungenakonakala kuze kube yilapho iziphene ziqinisekiswa ukuba zipheliswe.
(12) Iityhubhu apho i-strip iron butt welds kunye ne-D-joints zidibana ne-spiral welds zihlolwe yi-X-ray TV okanye ifilimu.
(13) Umbhobho ngamnye wensimbi uye wafumana uvavanyo loxinzelelo lwe-hydrostatic, kwaye uxinzelelo luvalwe nge-radially. Uxinzelelo lovavanyo kunye nexesha zilawulwa ngokungqongqo ngumbhobho wentsimbi uxinzelelo lwamanzi isixhobo sokubona microcomputer. Iiparamitha zovavanyo ziprintwa ngokuzenzekelayo kwaye zirekhodwe.
(14) Isiphelo sombhobho senziwe ngoomatshini bokulawula ngokuchanekileyo ukuqina kobuso besiphelo, i-angle ye-bevel kunye ne-edge ebomvu.

Iimpawu eziphambili zenkqubo yombhobho ojikelezayo:

a. Ngethuba lenkqubo yokwenza, i-deformation ye-steel plate ifana, uxinzelelo oluseleyo luncinci, kwaye umphezulu awuvelisi imikrwelo. Umbhobho wentsimbi ejiyileyo owenziweyo unokuguquguquka okukhulu kubungakanani kunye noluhlu oluchaziweyo lobubanzi kunye nobukhulu bodonga, ngakumbi kwimveliso yemibhobho enodonga olungqingqwa yodidi oluphezulu, ngakumbi imibhobho emincinci enodonga olungqingqwa.
b. Ukusebenzisa itekhnoloji ye-arc ye-arc enecala eliphindwe kabini, i-welding inokuqondwa kwindawo efanelekileyo, kwaye akukho lula ukuba neziphene ezifana nokungahambi kakuhle, ukuphambuka kwe-welding kunye nokungena okungaphelelanga, kwaye kulula ukulawula umgangatho we-welding.
c. Ukuqhuba ukuhlolwa komgangatho we-100% wemibhobho yensimbi, ukwenzela ukuba yonke inkqubo yokuvelisa ipayipi yensimbi iphantsi kokuhlolwa okusebenzayo kunye nokubeka iliso, ngokufanelekileyo ukuqinisekisa umgangatho wemveliso.
d. Zonke izixhobo zomgca wemveliso yonke inomsebenzi wokunxibelelana kunye nenkqubo yokufumana idatha yekhompyutheni ukuze ifezekise ukuhanjiswa kwedatha yexesha langempela, kwaye iiparitha zobugcisa kwinkqubo yokuvelisa zihlolwe yigumbi lokulawula eliphakathi.

Imigaqo yokupakishwa kwemibhobho ejikelezayo ifuna:
1. Imfuneko yomgaqo-siseko we-spiral steel stacking ukupakisha ngokweentlobo kunye neenkcukacha phantsi kwesiseko sokupakisha okuzinzileyo kunye nokuqinisekisa ukhuseleko. Iindidi ezahlukeneyo zemathiriyeli kufuneka zipakishwe ngokwahlukeneyo ukuthintela ukubhideka kunye nokukhukuliseka;
2. Akuvumelekanga ukugcina izinto ezidla intsimbi ejikeleze i-stack ye-spiral steel pipes;
3. Umzantsi wengqumba yombhobho wentsimbi ejikelezayo kufuneka ube phezulu, uqine kwaye ube mcaba ukuthintela imathiriyeli ukuba ifume okanye ikhubazeke;
4. Izinto ezifanayo zifakwe ngokwahlukileyo ngokomyalelo wokugcinwa;
5. Kwicandelo lemibhobho yensimbi ejikelezayo efakwe kwindawo evulekileyo, kufuneka kubekho iipads zokhuni okanye iintambo zamatye ngaphantsi, kwaye umgangatho wokupakisha uthambekele kancinane ukuququzelela ukukhutshwa kwamanzi, kwaye ingqalelo kufuneka ihlawulwe ekubekeni izinto ngokuthe tye ukuthintela ukugoba ukugoba;
6. Ubude bemibhobho yentsimbi ejikelezayo abuyi kuba ngaphezu kwe-1.2m yomsebenzi wezandla, i-1.5m yomsebenzi womatshini, kwaye ububanzi bestake abuyi kuba ngaphezu kwe-2.5m;
7. Kufuneka kubekho umjelo othile phakathi kwezitaki. Umjelo wokuhlola ngokuqhelekileyo ngu-0.5m, kwaye umjelo wokufikelela uxhomekeke kubukhulu bezinto eziphathekayo kunye noomatshini bokuthutha, ngokubanzi i-1.5-2.0m;
8. Intsimbi ye-angle kunye nentsimbi yeshaneli kufuneka ifakwe emoyeni ovulekileyo, oko kukuthi, umlomo kufuneka ujonge phantsi, kwaye i-I-beam kufuneka ibekwe ngokuthe nkqo. Umphezulu we-I-channel wentsimbi akufanele ujonge phezulu, ukwenzela ukuba ugweme ukuqokelela kwamanzi kunye nokugqwala;

9. Umzantsi wesitaki uphakanyisiwe. Ukuba indawo yokugcina impahla ikumgangatho wesamente onelanga, inokunyuswa nge-0.1m; ukuba ngumgangatho wodaka, kufuneka unyuswe nge-0.2-0.5m. Ukuba yibala elivulekileyo, umgangatho wekhonkrithi uya kunyuswa ngobude obuyi-0.3-0.5m, kwaye umhlaba wesanti kunye nodaka kufuneka ukhuliswe ngobude obuyi-0.5-0.7m.
