The automated inspection system of portal-type is designed for ultrasonic testing (AUT) of pipes and round bars made of various grades of steel with diameters ranging from 60 mm to 920 mm.

Inspection objects:
  • Oil-grade pipes according to API 5CT and 5L standards
  • Seamless and welded pipes
  • Boiler tubes
  • Round bars

Types of defects

  • For pipe inspection:
Detection of defects with longitudinal and transverse orientation relative to the pipe axis, as well as oblique defects. Additionally, lamination testing and wall thickness measurement are performed.
  • For bar inspection:
100% cross-sectional inspection of the bar for internal defects.

Inspection scenario

  • Linear transducer movement with rotating test object
In the portal-type AUT system, the transducer block moves in a straight line, while the test object—a pipe or round bar—remains stationary and rotates on turning rollers.
  • Coupling methods: Immersion, gap, or jet
  • Electronics options: Multi-channel UT or phased array (PA) technology
  • Water supply synchronized with transducer motion


This ensures precise defect detection in pipes and bars with high efficiency.
