Non-destructive testing technology with more manufacturers to use eddy current, ultrasonic flaw detection units combined in the laser diameter measuring unit, ultrasonic thickness measurement device. Production plant in the stainless steel pipe factory, from more than one link always has quality. This combination of detection units with advanced treatment systems, the measured signals of all the data and by computer processing, storage, automation and production efficiency. Precision straightening machine, cold and spin necking push the machine, long 6 to 8 polishing machine, full marking devices, are widely used the world's high-efficiency stainless steel pipe finishing equipment.
