Umbhobho we-LSAW(Longitudinal Submerged Arc-Welding Pipe), ebizwa ngokubaUmbhobho we-SAWL. Ithatha ipleyiti yentsimbi njengento ekrwada, iyibumbe ngomatshini wokubumba, emva koko wenze i-arc ye-arc enamacala amabini. Ngale nkqubo umbhobho wentsimbi we-LSAW uya kufumana i-ductility egqwesileyo, ukuqina kwe-weld, ukufana, iplastiki kunye nokutywinwa okukhulu.
Uluhlu lwedayamitha yombhobho we-LSAW likhulu kune-ERW, ngokuqhelekileyo ukusuka kwi-406mm ukuya kwi-2020mm. Ukusebenza kakuhle kukumelana noxinzelelo oluphezulu, kunye nobushushu obuphantsi bokumelana nokutyiwa.
Umbhobho we-SSAW(Spiral Submerged Arc-Welding Pipe), ebizwa ngokubaumbhobho we-HSAW(I-Helical SAW), i-welding line shape njenge-helix. Isebenzisa itekhnoloji ye-welding efanayo ye-Submerged Arc-Welding kunye nombhobho we-LSAW. Ngokwahlukileyo umbhobho we-SSAW ujijelwe ngokujiyileyo apho i-LSAW idityaniswe ngobude. Inkqubo yokuvelisa i-rolling strip yentsimbi, ukwenza ulwalathiso olujikelezayo lube ne-engile kunye nolwalathiso lweziko lombhobho, ukwenza kunye ne-welding, ngoko ke i-welding seam ikwi-spiral line.
Uluhlu lwedayamitha ye-SSAW yombhobho ukusuka kwi-219 mm ukuya kwi-2020 mm. Inxalenye yenzuzo sinokufumana ububanzi obuhlukeneyo bemibhobho ye-SSAW kunye nobukhulu obufanayo bomgca wentsimbi, kukho isicelo esibanzi somcu wentsimbi ekrwada, kunye ne-welding seam. kufuneka luphephe uxinezeleko oluphambili, intsebenzo entle yokuthwala uxinzelelo.
