NDT Services

To improve manufacturing quality and product reliability, components and structures are regularly inspected for discontinuities, defects or faults which may reduce their structural integrity leading to failure. Among the material testing methods developed for inspection purposes, Non-destructive testing (NDT) techniques present the advantages of leaving the components undamaged after inspection.

Petro-Tracking Services Limited inspection facilities are equipped with modern NDT equipments, approved practices, procedures, qualified and certified NDT Level I, II, technicians and in-house ASNT NDT III certified professionals, materials testing experts, welding inspection and quality control personnel.

Why NDT ?

NDT can be used to:
  1. Weeding out defective raw materials /components at the incoming stage itself instead of accepting and paying for it
  2. Detect defects that may occur during the manufacturing process before spending time and money on further processing of the defective materials
  3. Improve manufacturing techniques by inspecting the product during processing operations to maintain uniform quality and standard
  4. Detecting discontinuities at final stages of manufacturing to improve product reliability and safety during operation
  5. Inservice inspection to detect service induced flaws
  6. Ensure prevention of accidents and promote safety for workers and equipment during over hauling and maintenance
  7. Enhance the reputation of manufacturer as producer of quality products

4. Radiography

Radiographic testing - Gamma ray camera

Radiography is carried out using X-rays or Gamma rays. Radiographic testing (RT) is one of the most reliable and widely used NDT methods in industries. Works on the principles of differential absorption of radiation, radiography is used to detect internal flaws in castings and welds. Additional advantage with Radiography is the availability of permanent record for future reference. Petro-Tracking Services Limited has experienced Level 1, 2, 3 professionals to carry out the tests and interpretations accurately.

5. Visual Testing

Visual testing (VT) is one of the oldest and most widely used NDE methods to derive a multitude of useful information from a variety of material characteristics and properties. Visual examination is used in all stages of manufacturing and fabrication as a means of verifying conformance to standards and ensuring the quality levels are met and maintained in the final product. A great deal of specialized equipments, certified inspectors as per ASNT recommended practice SNT-TC-1A, technicians and NDT level III's exists for this purpose and can provide ASME 'U' stamp consultation on NDT.
