PAUT Solution for Small Tube Welds

>>Product Enquiry


This solution is suitable for testing small tube welds, with OD ranging from 20.32-114.3mm(0.84-4.5 inch).
  • Easy Installed: Simple buckle design to quick change links.
  • Slim Design: Enable to inspect pipes that have limited accessibility.
  • Efficiency: Support up to two PA probes to cover the whole welds at one time.
  • Precision: Smooth-rolling encoded movement to enable precise data acquisition and measurement.
  • Steady: Crawler can provide stable and constant pressure around the pipe full circumference.
The PAUT testing system includes PA flaw detector SyncScan/ SyncScan 2, low profile crawler LPS-01/ 02, PA probes with wedges, and special software.

Test Result (PAUT vs. X-ray)

We use LPS-01 to test three small diameter pipes. We’ve got the same test results of flaw size measured by PA and CR.

  • Testing lack of penetration flaw for pipe (78x10mm)

  • Testing strip-type flaw for pipe (45x8.0mm)

  • Testing no-fusion flaw for pipe (32x8.0mm)
