API 5L Welded Steel Pipe Manufacturing Process
Mtundu 1. Spiral Welded: Spiral welded zitsulo mapaipiamapangidwa ndi kuwotcherera mozungulira chitsulo, kupanga msoko wa helical. Njirayi imalola kupanga mapaipi akulu akulu ndipo nthawi zambiri imakhala yotsika mtengo pazinthu zina.
Kupaka ndi Kuchiza:Pofuna kukulitsa kukana kwa dzimbiri ndi kulimba, mapaipiwa amatha kuphimba ndi njira zosiyanasiyana zochizira, monga fusion bonded epoxy (FBE) kapena zokutira zamitundu itatu ya polyethylene (3LPE).
Type 2. Electric Resistance Welding (RW):Mphepete mwazitsulo zopangidwa ndizitsulo zimatenthedwa pogwiritsa ntchito mphamvu zamagetsi. Kuponderezedwa kumagwiritsidwa ntchito kuti apange m'mphepete palimodzi, kupanga chowotcherera chokhazikika popanda kufunikira kwa zinthu zodzaza.
Mtundu 3.Kuwotcherera kwa Longitudinal:
Submerged Arc Welding (SAW): Mphepete mwa chitoliro chopangidwa ndi chowotcherera pamodzi pogwiritsa ntchito njira yowonongeka ya arc, yomwe imaphatikizapo kugwiritsa ntchito arc yamagetsi ndi granular flux kuti apange weld wapamwamba kwambiri, wamphamvu.
Kuwotcherera kwa Arc Double Submerged (DSAW): Kwa mapaipi okhuthala, ma seam onse amkati ndi akunja amawotcherera, kuwonetsetsa kulowa kwathunthu ndi mphamvu.
