SAW SPIRAL PIPE-ON LINE BODY LAMINATION INSPECTION BY ULTRASONIC METHOD

The body lamination test can take place just after the welding during the pipe manufacturing process and can operate at high scanning speed.

   puce1504 Pipe manufacturing range :
    -Pipe diameter range :500 mm to 3000 mm
    -Wall thickness range:5 mm to 25 mm
    -Coil width range : 900 mm to 2000 mm

Environment

The UT system is designed to be placed very close to possible noise sources (plasma cutters,welding machines,frequency inverters ....)
The possible electromagnetic interference peaks are lowered and not detected.Besides the system can operate in difficults conditions (room temperature up to 50C and humidity up to 98%.
