Ultrasonic automatic testing equipment for WUT type welded pipe (spiral, longitudinal submerged arc and high frequency resistance welded pipe)
◆ Ultrasonic automatic testing for spiral welded pipe (double-sided submerged arc welding, pre-precision welding, etc.) weld and the full pipe.
◆ Ultrasonic automatic testing for longitudinal welded pipe (JCOE, UOE, etc.) weld and full pipe.
◆ Ultrasonic automatic testing for ERW/HFW resistance welded pipe weld and the full pipe.
◆ Weld longitudinal and transverse defect detection, tandem detection of weld blunt edge area and delamination detection of weld heat affect zone
◆ Blind zone of tube end: longitudinal and delamination detection ≤ 50mm; transverse detection ≤ 50+2×T (T is the wall thickness)
◆ Detection Method: spiral weld: water film method
Longitudinal welded pipe: water film method or water jet method
ERW/HFW welded pipe: water jet method
◆ API SPEC 5L 《Steel pipe specification of pipe line》(45 Edition)
◆ DEP220.127.116.11 （2011）《Pipe specification of shell pipe line》
◆ ASME A578/A578M-96 ASTM A53 ASTM A500 JIS G3444 GB/T 3091
◆ Q/SY GJX 101-2010《General technical requirements for steel pipes for natural gas transmission pipelines of the China Petroleum Pipeline Construction Project Department》
System Software (Function description，interface display)
1.The automatic detection results can be stored and printed, and the detection records (detection curves and related data) can be stored on the storage medium. The industrial computer could permanently store the continuous detection records. When the test results need to be modified, password authorization was needed.
2.Instantly display the quantity of genuine products and rejects in the flaw detector.
3.In the process of automatic detection, the system will automatically generate an audible and visual alarm when it detects defects or delamination and poor coupling thickness measurement.
4.The system has a pre-alarm function. The pre-alarm line can be set at will, but it must be lower than the alarm line.
5.After the sample tube calibration is completed, the relevant parameters can be stored in the industrial computer for use when the same specification is tested next time.
The form of mechanic structure
◆ Gantry beam type (traditional type)
◆ Truss structure form
◆ Lateral beam form
◆ It can also be customized according to the specific requirements of the user on site
Technical key points
