RT

Radiographic Testing

Uses radiation (X-rays or gamma rays) to produce images of the internal structure of welds, castings, and components, revealing voids, cracks, inclusions, and thickness variations.

More Info

Advantages

  • Excellent for detecting internal defects that are invisible on the surface
  • Provides a permanent visual record (film or digital images)
  • Highly reliable for weld quality verification
  • Works on a wide range of materials and thicknesses

Disadvantages

  • Requires strict radiation safety protocols and exclusion zones
  • Higher cost and longer setup time
  • Heavy equipment and licensing requirements

Best For

Critical welds on pipelines, pressure vessels, and high-integrity components in refineries and gas plants.

MT

Magnetic Particle Testing

Applies magnetic fields to ferromagnetic materials and uses iron particles to reveal surface and near-surface defects (cracks, seams, laps).

More Info

Advantages

  • Fast and relatively low cost
  • Highly sensitive to surface and slightly subsurface defects
  • Portable and effective on-site
  • Immediate results

Disadvantages

  • Limited to ferromagnetic materials (carbon steel, etc.)
  • Cannot detect deeply subsurface or internal defects
  • Requires surface preparation and post-cleaning
  • Demagnetization may be needed afterward

Best For

Weld inspections, forgings, and castings on rigs, pipelines, and structural steel in upstream and midstream operations.

PT

Penetrant Testing (Liquid / Dye Penetrant Inspection)

A liquid penetrant is applied to the surface, drawn into cracks by capillary action, then revealed with a developer powder or spray.

More Info

Advantages

  • Very effective for detecting tight surface-breaking cracks
  • Low cost and simple to perform
  • Works on both ferrous and non-ferrous materials
  • Highly portable and minimal equipment required

Disadvantages

  • Only detects surface-breaking defects
  • Requires thorough surface cleaning
  • Time-consuming (multiple steps and dwell times)
  • Not suitable for porous materials

Best For

Welds, castings, and machined parts where surface integrity is critical, especially in maintenance and fabrication shops.

UTT

Ultrasonic Thickness Testing / Ultrasonic Testing

Uses high-frequency sound waves to measure material thickness or detect internal flaws. UTT specifically focuses on remaining wall thickness.

More Info

Advantages

  • Excellent for measuring remaining wall thickness and detecting internal corrosion/erosion
  • Portable, safe (no radiation), and provides instant digital readings
  • Can inspect through coatings in many cases
  • Good for high-temperature surfaces

Disadvantages

  • Requires skilled technicians and proper calibration
  • Surface must be relatively clean and smooth for accurate readings
  • Limited by geometry and material attenuation in some cases
  • Interpretation can be operator-dependent

Best For

Pipeline integrity, pressure vessel corrosion monitoring, tank floor inspections, and condition-based maintenance programs across Western Canada.

HT

Hardness Testing

Measures the hardness of a material using methods such as Brinell, Rockwell, or Vickers to verify material properties and heat treatment condition.

More Info

Advantages

  • Quick and relatively inexpensive
  • Portable handheld units available for field use
  • Helps verify material strength and resistance to wear
  • Non-destructive in most cases (minor surface indentation)

Disadvantages

  • Only provides surface hardness (not bulk properties)
  • Requires proper surface preparation
  • Results can be affected by surface conditions or previous work hardening
  • Limited correlation to other mechanical properties in some materials

Best For

Verifying weld procedures, material acceptance, and evaluating potential degradation from fire exposure or improper heat treatment in oil & gas assets.

PMI

Positive Material Identification

Uses handheld XRF (X-ray fluorescence) or LIBS analyzers to determine the elemental composition of metals and verify they match specifications.

More Info

Advantages

  • Fast, on-site alloy verification
  • Prevents costly material mix-ups
  • Critical for safety and regulatory compliance
  • Minimal surface preparation required

Disadvantages

  • Surface must be clean and representative
  • Cannot detect all elements (especially light elements like carbon in some models)
  • Results are semi-quantitative in standard XRF
  • Requires certified equipment and trained operators

Best For

Incoming material verification, existing asset audits, weld filler material confirmation, and corrosion-resistant alloy (CRA) verification in refineries and chemical plants.
