System Design

1. System Introduction 

1. This off-line ultrasonic testing system can be used for big size tube testing ,with high flexible, high system stability characteristics.

2. Step :

2.1 Work piece will be neatly put onto the platform.

2.2:Work pieces will be put onto the orbit by the mechanical hand ,and then the workpiece willl move to the testing area, then pipe rotated ,probes move right and left .

2.3: when find defects, the instrument will automatic alarm, at the same time it will display the flaw signal.

2.4 :record and analyse the test results , automatic sort the qualified and unqualified, and then finish the detection

2.Testing object: seamless pipe , steel bar

3.Testing material : Carbon steel ,stainless steel,copper,aluminium,titanium and different kinds of non-ferrous and ferrous metals 

4. Testing speed : 0-8m/min 

5. Testing model : Pipe rotated ,probes move and scan right and left 

6. Testing Standard :

ISO 9303:1989---- Seamless and welded (except submerged arc-welded) steel tubes for pressure purposes —Full peripheral ultrasonic testing for the detection of longitudinal imperfections

ISO 9305:1989---- Seamless steel tubes for pressure purposes — Full peripheral ultrasonic testing for the detection of transverse imperfections

      1. The workpiece rotated at one place , can reduce the shake ,and the moving speed of the probe holder can be adjustment , so it is better to control the testing quality .

      2.Can be used to different kinds of diameter for the workpieces 

Metallurgy, machinery manufacturers, such as seamless pipe, titanium tube etc.

Steel Bar :titanium bars , precision steel bars ,aluminum bar etc.
