Njira zowotcherera zomwe zimagwiritsidwa ntchito popanga mapaipi akulu akulu onyamula madzi monga gasi kapena mafuta amaphatikizanso mbali ziwiri zowotcherera arc (DSAW) ndi kuwotcherera kwakutali (LSAW).
Chitoliro chachitsulo cha DSAW:
spiral weld
Chitoliro chachitsulo cha DSAW:
Kuwotcherera kwa Longitudinal
Chitoliro chachitsulo cha LSAW:
Kuwotcherera kwa Longitudinal
LSAW ndi imodzi mwa mitundu ya DSAW.
DSAW ndi chidule cha "double-sided submerged arc welding," mawu omwe amatsindika kugwiritsa ntchito njira imeneyi.
LSAW imayimira "Longitudinal Submerged Arc Welding," njira yodziwika ndi ma welds omwe amapitilira kutalika kwa chitoliro.
Ndikofunika kuzindikira kuti DSAW imaphatikizapo SSAW (Spiral Submerged Arc Welding) ndi LSAW mitundu ya chitoliro.
Kuwona kufanana ndi kusiyana pakati pa DASW ndi LSAW kwenikweni makamaka kuyerekeza pakati pa SSAW ndi LSAW.
Zofanana
Welding Technology
Onse a DSAW ndi LSAW amagwiritsa ntchito njira yowotcherera ya arc (SAW) yokhala ndi mbali ziwiri, pomwe kuwotcherera kumachitidwa nthawi imodzi mbali zonse zachitsulo kuti ziwongolere komanso kulowa mkati mwa weld.
Mapulogalamu
Amagwiritsidwa ntchito kwambiri m'magawo omwe amafunikira mipope yachitsulo ndi mainchesi akulu, monga mapaipi amafuta ndi gasi.
Mawonekedwe a Weld Seam
Pali chowotcherera chowoneka bwino mkati ndi kunja kwa chitoliro chachitsulo.
Kusiyana
Mtundu wa weld
DSAW: Ikhoza kukhala yowongoka (yowotcherera m'litali la chitoliro) kapena helical (wowotchera atakulungidwa mu mawonekedwe a helical kuzungulira thupi la chitoliro), malingana ndi ntchito ndi ndondomeko ya chitoliro.
LSAW: Msoko wowotcherera ukhoza kukhala wautali, pomwe mbale yachitsulo imapangidwira mu chubu ndikuwotcherera motalika.
Yang'anani pa ntchito zazitsulo zazitsulo
DSAW: Popeza DSAW ikhoza kukhala yowongoka kapena yozungulira, ndiyofunika kwambiri pazovuta zosiyanasiyana komanso ma diameter osiyanasiyana, makamaka pamene mapaipi aatali kwambiri amafunikira spiral DSAW ndiyoyenera kwambiri.
LSAW: Mapaipi achitsulo a LSAW ndi oyenera makamaka pazitukuko zamatawuni komanso ntchito zopanikizika kwambiri monga kuyenda kwamadzi ndi gasi.
Chitoliro Magwiridwe
DSAW: Spiral welded pipe ilibe ntchito yofanana ndi LSAW potengera kulekerera kupsinjika.
LSAW: Chifukwa cha kupanga kwake zitsulo mbale pogwiritsa ntchito JCOE ndi njira zina akamaumba, LSAW zitsulo chitoliro khoma akhoza kupirira katundu yunifolomu makina.
Mtengo ndi Kuchita Mwachangu
DSAW: Pamene DSAW chitoliro ndi spiral welded nthawi zambiri zotchipa ndi mofulumira kutulutsa ndi oyenera mapaipi mtunda wautali.
LSAW: Wowotcherera msoko wowongoka, pomwe akupereka mawonekedwe apamwamba, ndi okwera mtengo komanso pang'onopang'ono kupanga ndipo ndi oyenera kugwiritsa ntchito omwe ali ndi zofunikira zolimba kwambiri.
Kusankhidwa kwa DSAW kapena LSAW kumadalira zofunikira zenizeni za polojekitiyi, kuphatikizapo bajeti, zipsinjo zomwe chitoliro chiyenera kupirira, ndi zovuta kupanga ndi kukhazikitsa.Kumvetsetsa kufanana kwakukulu uku ndi kusiyana kungathandize kupanga chisankho choyenera pa ntchito inayake ya uinjiniya.
