Pulsed Eddy Current Technique

  • PECT is an advance electromagnetic inspection technology which majorly detect corrosion hidden under insulation in ferrous material. It is an effective method of quantifying defects in multi-layer structure.
  • PECT use square pulse signal to induced eddy current. PECT can penetrate more deeply in magnetic material than ECT(Eddy Current Technique).
  • PECT can also measures the thickness of object.

PECT can measure thickness through following things :
All insulation materials, coatings, fixed chicken wire, concrete, re-bars,corrosion product, stainless steel sheeting, aluminum sheeting, water marine growth, blistering scabs, through metallic mesh.

Application of PECT:
  • Corrosion under insulation on piping, vessels/columns skirts.
  • Corrosion under fireproofing of supports legs of storage spheres.
  • Flow accelerated corrosion.
  • Repair Wrap.
  • Remaining ligament underneath corrosion scabs.

Telescopic Poles

  • Cost for removal of insulation and re insulation is saved.
  • Reduced Inspection Time resulting in high productivity.
  • Grid mapping mode 2 to 10 time faster (usually <1 s).
  • Less operator dependent.
  • Less affected by liftoff variations, weather jacket overlap, straps.
  • Better detection of small defects.
  • Unaffected by structures above probes.
  • 6 meter length of telescopic pole enables to minimize scaffolding requirement.

NDTS becomes Remote Training Centre (RTC) of M/S Lavender International, UK

Effective February 2019, NDTS will be providing courses as per PCN/ISO 9712 in India through our partner M/S Lavender International, UK. Lavender International is a world leader in Non-destructive Testing (NDT) Training & Examination. They are accredited by major NDT organisations, to provide Training and Examinations suitable for internationally recognised central and employer based certification schemes.
