NDT Services

Comprehensive Non-Destructive Testing Solutions

We provide end-to-end Non-Destructive Testing (NDT) services for inspection, quality verification, and integrity assessment of pipelines, pressure equipment, structural welds, and HVAC piping systems.

Our NDT services support new construction, shutdowns, turnarounds, repairs, alterations, and in-service inspections, ensuring compliance with international codes, client specifications, and statutory regulations—without damaging the asset.

Industries Served

NDT Testing Methods

1. Visual Testing (VT)

First-Level Quality & Workmanship Inspection

Visual Testing (VT) is the foundation of all NDT activities, performed before, during, and after welding to ensure compliance with approved drawings, WPS, and workmanship standards.

Scope of VT

  • Joint fit-up & alignment checks
  • Root gap, bevel angle & edge preparation
  • Weld profile, reinforcement & undercut
  • Surface cracks, overlaps & arc strikes
  • Dimensional & orientation checks
  • Coating and surface condition inspection

Standards

ASME Section V, ISO 17637, AWS D1.1, Project Specifications

Surface Defect Detection for All Materials

PT/DPT is used to detect surface-breaking defects on ferrous and non-ferrous materials, especially where magnetic testing is not applicable.

Detectable Defects

  • Hairline cracks
  • Porosity
  • Pinholes
  • Surface laps & seams
  • Leak paths

Standards

ASME Section V, ASTM E165, ISO 3452

Internal Defect Detection & Thickness Measurement

Conventional Ultrasonic Testing (UT) uses high-frequency sound waves to detect internal defects and measure remaining wall thickness.

Capabilities

  • Weld defect detection
  • Thickness gauging
  • Corrosion & erosion monitoring
  • Lamination detection
  • Remaining life evaluation

Standards

ASME Section V, ASTM E213, ISO 17640

Surface & Near-Surface Defect Detection

MPI is applied to ferromagnetic materials to identify surface and near-surface discontinuities by magnetic flux leakage.

Detectable Defects

  • Cracks
  • Seams
  • Laps
  • Fatigue damage
  • Grinding cracks

Standards

ASME Section V, ASTM E709, ASTM E1444

Volumetric Weld Inspection

RT uses X-Ray or Gamma Ray radiation to produce images of internal weld quality, identifying volumetric defects.

Detectable Defects

  • Porosity
  • Slag inclusions
  • Incomplete penetration
  • Internal cavities

Standards

ASME Section V, API 1104, ASTM E94

Advanced High-Resolution Weld Inspection

PAUT is an advanced ultrasonic technique using electronically steered sound beams to generate real-time, high-resolution images of welds and components.

Key Advantages

  • Superior detection of planar defects
  • Accurate defect sizing & positioning
  • No radiation – safe for live plants
  • Permanent digital data storage
  • Faster inspection & approvals

Standards

ASME Section V (Art. 4 & 14), API 1104, ISO 13588
