Umbhobho weSpiral (SSAW) ngumbhobho wentsimbi wekhabhoni ojikelezayo owenziwe ngomtya wentsimbi njengesixhobo sokukhuselwa, usoloko ukhutshelwa ngokufudumeleyo, kwaye udityaniswe yinkqubo yokuwelda yearc ezenzekelayo enamacala amabini. Isetyenziswa kakhulu kubunjineli bokubonelela ngamanzi, i-petrochemical, ikhemikhali, amandla ombane, ezolimo Ukuthuthwa kwe-Fluid kwimimandla yokunkcenkceshela kunye nezakhiwo zikamasipala: ukunikezelwa kwamanzi, ukuhambisa amanzi, ubunjineli bokucocwa kwamanzi amdaka, ukuthuthwa kwamanzi olwandle.
Kuthutho lwerhasi yendalo: irhasi yendalo, umphunga, igesi engamanzi.
Ukusetyenziswa kolwakhiwo: isetyenziselwa ukufumba, iibhulorho, iidokhi, iindlela, izakhiwo, imibhobho yokufunxa elunxwemeni, njl.

Kufuneka kubekho umjelo othile phakathi kokupakishwa kwezixhobo zokupakisha umbhobho we-spiral welded. Ububanzi bomjelo wokuhlola ngokuqhelekileyo malunga ne-0.5m. Ububanzi bomjelo wokutya buxhomekeke kubukhulu bezinto kunye noomatshini bokuthutha, ngokubanzi 1.5 ~ 2m. Ubude bemibhobho yentsimbi ejikelezayo abuyi kudlula kwi-1.2m yomsebenzi wezandla, i-1.5m yomsebenzi womatshini kunye ne-2.5m yobubanzi bokupakisha. Ngokomzekelo, kwimibhobho yentsimbi ebekwe kwindawo evulekileyo, i-dunnage okanye amatye e-strip kufuneka abekwe phantsi kombhobho wensimbi ojikelezayo, kwaye umphezulu wokupakisha kufuneka uthambekele kancinane ukuze uququzelele ukukhupha amanzi. Nikelani ingqalelo ukuba ngaba umbhobho wensimbi usicaba ukuphepha ukugoba kunye nokuguqulwa kombhobho wensimbi.

Ukuba igcinwe kwindawo evulekileyo, ukuphakama komgangatho wesamente kufuneka kube malunga ne-0.3 ~ 0.5m, kwaye ukuphakama komgangatho wesanti kufuneka kube phakathi kwe-0.5 ~ 0.7m. Amandla ombhobho odityanisiweyo we-spiral uphezulu ngokubanzi kunombhobho odityanisiweyo othe tye, kwaye indawo engenanto emxinwa ingasetyenziselwa ukuvelisa umbhobho odityanisiweyo omkhulu, kwaye indawo engenanto yobubanzi obufanayo ingasetyenziselwa ukuvelisa umbhobho odityanisiweyo nge. ezahlukeneyo umbhobho idayamitha. Nangona kunjalo, xa kuthelekiswa nombhobho ochanekileyo wobude obufanayo, ubude be-weld bunyuswe ngama-40 ~ 100%, kwaye isantya sokuvelisa siphantsi. Emva kokusika kumbhobho wentsimbi enye, ibhetshi nganye yemibhobho yentsimbi kufuneka ihlolwe ngokungqongqo okokuqala ngqa ukujonga iipropati zomatshini, ukwakheka kweekhemikhali, imeko yokudityaniswa kwe-weld, umgangatho womphezulu wombhobho wentsimbi kunye nokulungiswa ngovavanyo olungonakalisi. ukuqinisekisa ukuba iteknoloji yokwenza umbhobho ifanelekile. ukuba ifakwe ngokusemthethweni kwimveliso.
