PAUT Auto Detection System For Welded Pipe

◆ Automatic ultrasonic detection of welded seam and whole pipe body of spiral welded pipe (double-sided submerged arc welding, pre-finish welding, etc.).

◆ Automatic ultrasonic detection of welded seams and full pipe bodies of straight seam welded pipes (JCOE, UOE, etc.).

◆ Automatic ultrasonic detection of weld seam and whole pipe body of resistance welded pipes such as ERW/HFW pipes.

◆ Longitudinal and transverse defect detection in welded seams, crosstalk detection in welded seams with blunt edges and HAZ delamination detection in welded seams.

◆ Pipe end blind zone: longitudinal and delamination detection ≤ 50mm; transverse detection ≤ 50 + 2 × T (T is wall thickness)

Testing method: Spiral weld: water path method

Straight seam welded pipe: water film method or water jet method

ERW/HFW Welded Pipe: Water Jet Method

◆ API SPEC 5L Specification for Pipeline Steel Pipe (45th Edition)

◆ DEP31.40.20.37 (2011) Shell Pipe Line Pipe Specification

◆ ASME A578/A578M-96 ASTM A53 ASTM A500 JIS G3444 GB/T 3091

◆ Q/SY GJX 101-2010 "General Technical Conditions for Steel Pipes for Natural Gas Transmission Pipelines of China Petroleum Pipeline Construction Project".

◆ Gantry beam type (traditional way)

◆ Truss structure form

◆ Sidewall beam form

◆ Customized according to the specific requirements of the user's site.

◆ Automatic test results can be stored and printed, and test records (test curves and their related data) can also be stored on the storage media, and the IPC permanently stores continuous test records. When the test results need to be modified, use password authorization.

◆ Instantly displays the quantity of positives and rejects on the flaw detection instrument screen.

◆ During automatic detection, when the system checks for defects or poor coupling of delamination and thickness measurement, the system will automatically generate an audible and visual alarm.

◆ The system has a pre-alarm function. The pre-alarm line can be set arbitrarily, but must be lower than the alarm line.

◆ After the calibration of the sample pipe is completed, the relevant parameters can be stored in the IPC for the next test of the same specification to be called up.
