Ultrasonic flaw detection: We could know the inner trouble for steel pipes through the development of internal and external welds of base metals and the 100% check of welds.
X-ray inspection: 100% x-ray from internal and external industrial television inspection image processing system for each kind of steel pipe is to ensure the use of detection sensitivity.

Of course, the pressure test, shear molding and other checks would be necessary too for each kind of steel pipes in order to guarantee the high quality of steel pipe.
