Umbhobho odityanisiweyo we-Spiralimveliso isebenzisa ikhoyili eshushu esongiweyo.Umxholo we-alloy wekhoyili uhlala uphantsi kunamabakala afanayo epleyiti yensimbi, uphucula i-weldability ye-spiral welded pipe.Ngenxa ulwalathiso rolling of spiral welded umbhobho ikhoyili ayikho perpendicular ukuya kwicala axis umbhobho, ukuxhathisa crack of spiral welded umbhobho izinto.

Ngenxa yentsebenzo eyodwa yombhobho ojikelezayo, xa kuqhushumba umbhobho odityanisiweyo we-spiral, i-weld yabandezeleka uxinzelelo kunye noxinzelelo oluncinci luncinci, ukuqhushumba komlomo akusiyo imvelaphi ye-spiral weld, ngoko ke ukhuseleko oluphezulu.I-Spiral weld kufuphi nesiphene kunye ne-parallel spiral weld force incinci, ngoko ke umngcipheko wokwandisa awukho.

Umbhobho wentsimbi ophantsi koxinzelelo lwangaphakathi, ngokuqhelekileyo eludongeni kwizinto ezimbini eziphambili zokusetyenziswa kwamandla, uxinzelelo lwe-radial δY kunye noxinzelelo lwe-axial δX.Uxinzelelo lwesiphumo se-Weld δ = δY (l/4sin2α + cos2α) 1/2, leyo, α i-engile ye-helix ye-spiral weld pipe.I-engile ye-helix yombhobho we-spiral weld ngokubanzi ngama-50-75 degrees, ngoko ke i-spiral weld isiphumo soxinzelelo olukhulu.Kumsebenzi ofanayo phantsi koxinzelelo lwedayamitha efanayo spiral welded umbhobho umbhobho ukutyeba kungancitshiswa kakhulu, spiral umbhobho plant singenziwa kwikharibha encinane.
