Concrete Rebar Reinforcement – When is it necessary

Concrete Rebar Reinforcement – When is it necessary

By adding rebar reinforcement to the concrete surface, you can easily make the surface much more robust and resistant to cracks. Concrete surfaces that often carry heavy trucks or machinery do not need concrete rebar reinforcement; however, they are required to withstand tension forces. With the help of rebar reinforcement, the tensile strength of concrete […]

Acceptance Criteria

Minimum defect depth and length (FBH)

  • 0.7 mm FBH from 15—60 mm dia
  • 1.2 mm FBH above 60 dia

 
Minimum defect depth and length (SDH)

  • 0.5 mm x 10 mm {from 15—120 mm dia)
  • 0.3 mm SDH sensitivity can deduced by
    extrapolation depending on material SNR.

Phased Array Auto Ultrasonic Testing Salient Features

Phased Array Technology

Phased Array testing is a specialized type of ultrasonic testing that uses sophisticated multi- element array transducers and powerful instrumentation/software to steer ultrasonic beams through the test piece and map returning echoes.

No rotating movement, only electronic scanning is done:

  • Depth focalization for bar volume inspection (LW)
  • Electronic steering for bar surface inspection (SW)

Quality Highlights:

Capacity — 15 to 120 mm dia. Full bar volume inspection
