Imibhobho yentsimbi eSpiral isetyenziswa ikakhulu kwiiprojekthi zonikezelo lwamanzi, ishishini lepetrochemical, ishishini lemichiza, ishishini lamandla ombane, ukunkcenkceshela kwezolimo, kunye nokwakhiwa kwedolophu. Imibhobho yentsimbi ye-Spiral iphakathi kweemveliso eziphambili ze-20 eziphuhliswe kwilizwe lam. Ukuthutha ulwelo: unikezelo lwamanzi kunye nokukhupha amanzi. Ukuthutha igesi: irhasi yamalahle, umphunga, igesi yepetroleum engamanzi. Ngeenjongo zesakhiwo: ukupakisha imibhobho, iibhulorho; imibhobho yeedokhi, iindlela, izakhiwo zokwakha, njl. Umbhobho wentsimbi ojikelezayo wondla umcu kwiyunithi yombhobho odityanisiweyo. Emva kokugqithwa ngama-roller amaninzi, umcu ugotywa ngokuthe ngcembe ukuze wenze umbhobho ojikelezayo ongenanto kunye ne-gap yokuvula. Lungisa inani lokunciphisa i-roller extrusion ukulawula i-gap ye-weld phakathi kwe-1-3mm, kwaye wenze iziphelo zombini ze-welding joint flush.

Umahluko phakathi kombhobho wentsimbi ejikelezayo kunye nombhobho wentsimbi ochanekileyo
Imibhobho yentsimbi ye-Spiral inokwahlulwa ibe ngamacandelo amabini ngokweendlela zokuvelisa: i-spiral kunye ne-seamed. Imibhobho yentsimbi ethungelweyo ibizwa ngokuba yimibhobho yentsimbi yomthungo othe tye. Imibhobho yentsimbi ejikelezayo inokwahlulwa ibe yimibhobho eshushu eqengqelekayo engenamthungo, imibhobho etsalwa ngokubanda, imibhobho yentsimbi echanekileyo, imibhobho eyandiswe ngobushushu, imibhobho ejikelezayo ebandayo, kunye nemibhobho ekhutshiweyo ngokweendlela zokuvelisa. Imibhobho yentsimbi ye-Spiral yenziwe nge-carbon steel high-quality okanye i-alloy steel kwaye inokwahlulwa ibe yi-hot-rolled and cold-rolled (drawn). Eyona nto iphambili yombhobho wensimbi ovunguzayo kukuba ayinayo i-welding seams kwaye inokumelana noxinzelelo olukhulu.

Iimveliso zinokuba rhabaxa kakhulu njengesamente okanye iindawo ezitsalwa ngokubanda. Imibhobho yentsimbi edityanisiweyo yohlulwe ibe yimibhobho edityanisiweyo yomlilo, imibhobho edityaniswe ngombane (i-resistance welded), kunye nemibhobho edityanisiweyo yearc ezenzekelayo ngenxa yeenkqubo zabo zokuwelda ezahlukeneyo. Ngenxa yeendlela zabo zokuwelda ezahlukeneyo, zahlulwe zaba yimibhobho edityanisiweyo ethe tye kunye nemibhobho edityanisiweyo. Zikwahlulwe ngokwemibhobho edityanisiweyo engqukuva ngenxa yeemilo zazo zesiphelo kunye nemibhobho edityanisiweyo enemilo ekhethekileyo (isikwere, esicaba, njl.njl.) imibhobho edityanisiweyo.

Imibhobho yentsimbi edityanisiweyo yenziwe ngeepleyiti zentsimbi ezigalelwe kwiimilo ze-tubular kwaye zidityaniswe ngemithungo ye-butt okanye i-spiral seams. Ngokubhekiselele kwiindlela zokuvelisa, zahlulwe zibe yimibhobho yentsimbi edityanisiweyo yokuthutha ulwelo oluphantsi koxinzelelo, i-spiral seam yombane edityanisiweyo nemibhobho yentsimbi, imibhobho yentsimbi edityanisiweyo ngokuthe ngqo, imibhobho edityanisiweyo yombane, njl njl. imibhobho yegesi kumashishini ahlukeneyo. I-Welding ingasetyenziselwa imibhobho yamanzi, imibhobho yegesi, imibhobho yokufudumeza, imibhobho yombane, njl.

Imibhobho yentsimbi echanekileyo yimveliso evele kwiminyaka yamuva nje. Ubukhulu becala banonyamezelo olungqongqo kunye noburhabaxa kumngxuma wangaphakathi kunye nemilinganiselo yodonga lwangaphandle. Umbhobho wensimbi ochanekileyo yimbhobho yensimbi ephezulu echanekileyo eqhutywe ngumzobo obandayo okanye ukufudumala okushushu. Ngenxa yokuba akukho maleko we-oxide kwiindonga zangaphakathi nangaphandle zemibhobho yentsimbi ecolekileyo, akukho kuvuza phantsi koxinzelelo oluphezulu, ukuchaneka okuphezulu, ukukhanya okuphezulu, akukho luguquko ekugobeni okubandayo, akukho kuqhekeka ekugqabhukeni nasekubetheleni, njl. njl., isetyenziswa ikakhulu ukuvelisa iimveliso ezine-pneumatic okanye i-hydraulic components, njengeesilinda okanye i-oil cylinder.
