Njira Yopangira Chitsulo cha API 5L Welded Steel Pipe

Mtundu 1. Wolukidwa ndi Spiral: Mapaipi achitsulo ozungulira olumikizidwaAmapangidwa pogwiritsa ntchito kuluka kwachitsulo mozungulira, ndikupanga msoko wozungulira. Njirayi imalola kupanga mapaipi akuluakulu ndipo nthawi zambiri imakhala yotsika mtengo kwambiri pa ntchito zina.
Kuphimba ndi Chithandizo:Kuti mapaipi awa apitirize kukana dzimbiri komanso kulimba, amatha kupangidwa ndi njira zosiyanasiyana zophikira ndi kukonza, monga fusion bonded epoxy (FBE) kapena three-layer polyethylene (3LPE).

Mtundu Wachiwiri. Kuwotcherera Kotsutsana ndi Magetsi (ERW):M'mphepete mwa chingwe chachitsulo chopangidwacho chimatenthedwa pogwiritsa ntchito mphamvu yamagetsi. Kenako mphamvu imayikidwa kuti ipange m'mphepete pamodzi, ndikupanga solid-state weld popanda kufunika kwa zinthu zodzaza.

Mtundu 3.Kuwotcherera Kwautali:

Kuwetsa Arc Yokhala Ndi Madzi (SAW): M'mphepete mwa chitoliro chopangidwacho zimalumikizidwa pamodzi pogwiritsa ntchito njira yowetsa arc yokhala ndi madzi, yomwe imaphatikizapo kugwiritsa ntchito arc yamagetsi ndi granular flux kuti apange weld yapamwamba komanso yamphamvu.
Kuwotcherera Arc Yothira Madzi Kawiri (DSAW): Pa mapaipi okhuthala, mipata yamkati ndi yakunja imawotcherera, zomwe zimathandiza kuti mapaipiwo alowe bwino komanso akhale olimba.
