Hydel / Thermal Power Stations

Since 1977, JIACCO PAKISTAN (PVT) LTD has been providing specialized Non-Destructive Testing (NDT) and inspection services to Hydel and Thermal Power Stations across Pakistan. Power generation facilities operate under extreme mechanical and thermal stresses, making regular inspection and integrity monitoring essential for ensuring reliable and uninterrupted power supply. With decades of experience in industrial inspection, JIACCO supports the power sector by delivering high-quality NDT services for construction projects, routine maintenance, and major shutdown inspections.

Hydropower and thermal power plants contain critical components such as pressure vessels, boilers, steam turbines, heat exchangers, pipelines, penstocks, storage tanks, and structural welds that must be periodically inspected to detect defects, corrosion, fatigue cracks, and other structural weaknesses. Our highly qualified NDT technicians and radiography personnel use advanced inspection techniques to identify defects without damaging the equipment, helping plant operators maintain safety, efficiency, and compliance with international engineering standards.

JIACCO’s inspection services have supported major power generation facilities in Pakistan, including hydropower installations such as

  • Tarbela Dam
  • Mangla Dam
  • Ghazi Barotha Hydropower Project. Our services also extend to thermal power stations and independent power producers such as
  • Hub Power Company Limited
  • Kot Addu Power Company Limited
  • Water and Power Development Authority facilities across the country.

Specialized NDT Services for Power Plants

Our comprehensive range of inspection techniques is specifically designed to meet the demanding requirements of power generation facilities. These services include:

  • Industrial Radiography (Gamma Radiography) using Iridium-192, Selenium-75, and Cobalt-60 for weld inspection in boiler tubes, pressure vessels, and pipelines.
  • Ultrasonic Testing (UT) for weld examination, thickness measurement, and corrosion monitoring in piping systems and structural components.
  • Magnetic Particle Testing (MT) for detection of surface and subsurface discontinuities in ferromagnetic materials.
  • Liquid Penetrant Testing (PT) for identifying surface cracks and defects in non-porous materials.
  • Hardness Testing for weld qualification and heat-affected zone evaluation.
  • Corrosion monitoring and thickness surveys for pipelines, tanks, and high-temperature equipment.
  • Inspection services during plant shutdowns, commissioning, and maintenance turnarounds.

Ensuring Safety and Operational Reliability

Power plants operate continuously under high temperatures, pressures, and mechanical loads. Regular NDT inspections are essential to detect early signs of material degradation and prevent unexpected equipment failures. By utilizing advanced testing methods and strict safety procedures, JIACCO PAKISTAN (PVT) LTD helps power plant operators maintain the structural integrity and operational reliability of critical equipment.

With over four decades of experience in the energy sector, JIACCO remains committed to supporting Pakistan’s power generation industry by delivering reliable, accurate, and internationally compliant NDT inspection services that ensure safe and efficient power plant operations.
