X42 SSAW Pipe Spiral Welded Tube
Tsegulani:
M'munda wa mapaipi achitsulo, njira zosiyanasiyana zowotcherera zimagwiritsidwa ntchito kuti akwaniritse kulumikizana kwapamwamba komanso kodalirika.Njira imodzi yotere ndikuwotcherera kwa arc kozungulira(SAW), yomwe imagwira ntchito yofunika kwambiri popanga chitoliro cha X42 SSAW.Monga mtsogoleri wamakampani, Cangzhou Spiral Steel Pipe Group Co., Ltd., yomwe imadziwika ndi mtundu wake wa Wuzhou, imatsatira miyezo yapadziko lonse lapansi ndikuwonetsetsa kuti zinthu zake (kuphatikiza X42 spiral submerged arc welded pipe) zikukumana ndi API Spec 5L, ASTM A139, ASTM A252 ndi EN 10219. Mubulogu iyi tikufufuza za dziko lochititsa chidwi la chitoliro cha X42 SSAW, kuwonetsa ubwino wogwiritsa ntchito kuwotcherera kwa spiral submerged arc popanga chitoliro chowotcherera mozungulira.
Phunzirani za Spiral Submerged Arc Welding (SAW):
Kuwotcherera kwa Spiral submerged arc, komwe kumadziwikanso kuti SAW, ndi njira yapadera yowotcherera yomwe imagwiritsidwa ntchito popanga mapaipi owotcherera mozungulira mongaChitoliro cha X42 SSAW.Njirayi imaphatikizapo kusungunula waya ndi zitsulo zoyambira pogwiritsa ntchito kutentha komwe kumapangidwa ndi kuyaka kwa arc pakati pa waya ndi kutulutsa pansi pazitsulo.Chigawo cha flux chimagwira ntchito ngati chotchinga choteteza, kuteteza zowonongeka zam'mlengalenga kuti zisasokoneze ndondomeko ya soldering.Njirayi ili ndi maubwino angapo kuposa njira zina zowotcherera.

Kuyesedwa kwa Hydrostatic
Ubwino wa kuwotcherera kwa spiral submerged arc:
1. Ma welds okhazikika komanso apamwamba kwambiri: Njira ya SAW yomwe imagwiritsidwa ntchito mu chitoliro cha X42 SSAW imapanga ma welds a yunifolomu komanso apamwamba kwambiri.Pamene arc imalowetsedwa m'madzi, imapanga malo olamulidwa omwe amateteza malo otsekemera kuchokera kuzinthu zakunja, kuonetsetsa kuti mgwirizanowu ndi wodalirika.Izi zimapangitsa kupanga mapaipi ozungulira ozungulira omwe ali ndi mphamvu zapadera komanso olimba.
2. Kuchita bwino kwambiri: Kuwotcherera kwa Spiral submerged arc kumapereka mphamvu zambiri chifukwa cha mawonekedwe ake odzipangira okha.Njirayi imaphatikizapo kudyetsa kosalekeza kwa waya wowotcherera, zomwe zimapangitsa kuti pakhale zokolola mwachangu ndikusunga zolondola.Miyezo yokwera kwambiri komanso kudalira pang'ono pantchito yamanja kumathandizira kuti pakhale zogwira mtima komanso zotsika mtengo.
3. Oyenera ntchito zosiyanasiyana: X42 SSAW chitoliro chopangidwa ndi spiral submerged arc kuwotcherera amagwiritsidwa ntchito kwambiri m'mafakitale ambiri.Mapaipiwa amagwiritsidwa ntchito pamayendedwe amafuta ndi gasi, mapaipi amadzi, zomangira zothandizira, zomanga, ndi zina zambiri.Kusinthasintha komanso kudalirika kwa chubu la X42 SSAW kumapangitsa kuti ikhale yabwino pamapulogalamu ovuta.
4. Kupititsa patsogolo makina amakina: Njira ya SAW imatsimikizira kuwongolera bwino kwa magawo owotcherera pakupanga mapaipi a X42 ozungulira ozungulira arc welded.Kuwongolera uku kumatha kukulitsa zida zamakina, kuphatikiza kulimba kwamphamvu, kulimba kwa zokolola komanso kulimba kwamphamvu.Chotsatira chake, mapaipiwa amatsutsana kwambiri ndi mphamvu zakunja ndipo ali oyenera ngakhale malo ovuta.
Pomaliza:
Tikafufuza dziko la spiral submerged arc kuwotcherera mu X42 SSAW kupanga chitoliro, zikuwonekeratu chifukwa chake njirayi imagwiritsidwa ntchito kwambiri pamakampani azitsulo.Kuwotcherera kwa Spiral submerged arc kumapereka zabwino zambiri monga ma weld seams osasinthasintha, kuchulukitsidwa kwachangu, kusinthasintha komanso kuwongolera makina, kuwonetsetsa kuti mapaipi owotcherera mozungulira, monga mapaipi achitsulo a X42 SSAW opangidwa ndi Cangzhou Spiral Steel Pipe Group Co., Ltd., amakumana ndi apamwamba kwambiri makhalidwe abwino.Chifukwa chake, potengera kudalirika, kulimba komanso magwiridwe antchito, chubu la X42 SSAW limatsimikizira kuti ndi chisankho chabwino kwambiri pazogwiritsa ntchito zosiyanasiyana zamakampani.
