Kaʻina Hana Hana

ʻO ke kaʻina hana o ka hana ʻana i ka Longitudinal Submerged-arc Welded (LSAW) Pipe penei:

ʻO ka nānā ʻana o ka papa Ultrasonic → ka wili ʻana i ka lihi → pre-bending → forming → Pre-welding → Internal welding → External welding → Ultrasonic inspection → X-ray inspection → Expansion → hydraulic test →l. Chamfering → Ultrasonic inspection → X-ray inspection → magnetic particle inspection at the tube end
