Chiyambi cha Gulu la Chitoliro cha Welded Steel

▇ ▍ Kufotokozera

 

Welded zitsulo chitoliro analengedwa ntchito lathyathyathya zitsulo mbale kapena zitsulo n'kupanga, ndi kupanga ndondomeko amalenga seams mu thupi lake.Makamaka, mipope yachitsulo ikapangidwa, mbale yachitsulo kapena chingwe chimapindika ndikumangirizidwa kukhala chozungulira, chitoliro chachikhalidwe kapena mawonekedwe a square. njira kuwotcherera.Mwachitsanzo, chitoliro cha LSAW chimawotcherera motalika, ndipo chitoliro cha SSAW chimakhala chozungulira.ERW chitoliro ndi magetsi kukana welded, zomwe zimabweretsa msoko kuti amayendera limodzi pamodzi ndi chitoliro thupi.

Mapaipi owotcherera othamanga kwambiri amakhala ong'ambika mowongoka, koma mapaipi achitsulo omwe amawotcherera mowongoka sikuti amakhala owotcherera pafupipafupi.The high-frequency straight-slit-slit electric resistance welded welded steel pipe imapangidwa ndi mawonekedwe a khungu komanso kuyandikira kwaposachedwa kwapanthawi yayitali pambuyo poti mbale yotenthetsera yamoto imapangidwa ndi makina opangira, ndipo m'mphepete mwa chubu mulibe kanthu. kutenthedwa ndi kusungunuka, ndi kuwotcherera kuthamanga kumachitika pansi pa makina osindikizira kuti azindikire kupanga.The mkulu pafupipafupi kukana welded zitsulo chitoliro ndi wosiyana ndi wamba welded chitoliro kuwotcherera ndondomeko.Kuwotcherera kumapangidwa ndi zinthu zapansi za thupi lachitsulo, ndipo mphamvu yamakina ndi yabwino kuposa chitoliro chowotcherera.Pamwamba pake ndi yosalala, yolondola kwambiri, yotsika mtengo, ndipo imakhala ndi kutalika kwa msoko wocheperako, womwe umapindulitsa pakuphimba kwa 3PE anti-corrosion.

Longitudinal kumizidwa arc welded amapangidwa pogwiritsa ntchito sing'anga umodzi ndi mbale wandiweyani monga zopangira, kukanikiza (kugudubuza) mbale zitsulo mu nkhungu kapena kupanga makina mu chubu akusowekapo, ntchito iwiri amambali kumizidwa Arc kuwotcherera, ndi kukulitsa m'mimba mwake.The zitsulo mbale chakudya kuchuluka akhoza basi kusinthidwa malinga ndi magulu osiyanasiyana zitsulo, makulidwe khoma, ndi mbale m'lifupi.Pa nthawi yomweyo, mapindikidwe chipukuta misozi ntchito bwino kupewa zotsatira zoipa nkhungu mapindikidwe pa kupanga ndi kuonetsetsa flatness wa kutalika kwa mbale zitsulo pa ndondomeko kukanikiza.Njira yodyetserako imakhala yofanana pakupanga, kuwonetsetsa kuti chubu chilibe kanthu komanso kusalala kwa m'mphepete mwa kuwotcherera.Chomalizacho chimakhala ndi mawonekedwe osiyanasiyana, ndipo weld imakhala yolimba bwino, yapulasitiki, yofanana, komanso yolumikizana.Ili ndi ubwino wa kukula kwa chitoliro chachikulu, makulidwe a khoma la chitoliro, kukana kwamphamvu kwambiri, kukana kutentha pang'ono, ndi kukana kwamphamvu kwa dzimbiri.

Spiral welded chitoliro (SSAW chitoliro, amatchedwanso HSAW chitoliro).Chitolirocho amapangidwa ndi spiral submerged arc kuwotcherera luso.Mipope yowotcherera yozungulira imapangidwa pogwiritsa ntchito mbale zocheperako kapena zopindika zotentha, zomwe zimachepetsa mtengo wawo wopanga kwambiri.Mzere wowotcherera umawoneka ngati helix.Njira yowotcherera yozungulira imalola kupanga mapaipi akulu akulu oyenerera kunyamula mafuta ndi gasi wambiri.Mapaipi ena a SSAW m'mbiri yakale anali ocheperako pang'ono.
