Radiography / RT
Most weldments of steel pipes in energy sector require some method of testing to determine the quality of the welding. A common method of testing is by radiographic examination. Radiographic testing aims to record images of flaws introduced into the welds. These could be process defects (e.g. porosity, lack of fusion) or service-related conditions (e.g. corrosion-cracks). Radiographic inspection is carried out utilizing radioactive sources such as Ir-192, Se-75 or Co-60 and also with X-ray irradiating apparatus. Our technicians are highly experienced not only in the use of these radioactive sources and X-Ray equipment but also take pride in holding a clean safety record on all projects undertaken.
Ultrasonic Examination / UT
Lamination checking, thickness measuring, corrosion/erosion monitoring, weld examination in plates, pipes, nozzle and node configurations, flaw detection in forgings, castings and the like. Mechanized ultrasonic scanning systems for the examination of pipeline welds. Advanced ultrasonic inspection techniques including time flight diffraction.
Magnetic Particle Inspection ( Test)/ MPT
Flaw detection, using current flow (AC/HWDC) magnetic flux induction and permanent magnet techniques, with wide variety of visual aids including fluorescent and daylight viewing inks and powders at ambient and elevated temperatures.
Liquid Penetrant Examination (Test)/ LPT
This method of testing is suitable for detecting defects open to the surface only and on any material that is essentially nonporous. A bright colored penetrant or a fluorescent ink is sprayed on the surface of the component to be inspected. The penetrant will be drawn into any surface imperfections or cracks. After the excess penetrant is removed, a thin layer of developer is then applied. The penetrant will then be drawn out of the defects and made visible with use of visible light or ultraviolet light, as appropriate.
By vacuum box testing, bubble and/or gas leakage systems. Ultrasonic system also valid.
Employing portable manual, hydraulic or electronic instruments.
Meters, gauges, combs and the like for measuring paint, epoxy and ‘plastic’ coatings, holiday detectors for coal-tar or bitumen wrapping.
Visual Testing (VT)
Also known as Visual Inspection, VT is the one NDT method used extensively to evaluate the condition or the quality of a weld or component. It is easily carried out, inexpensive and usually doesn’t require special equipment. It is used for the inspection of welds and other components where quick detection and the correction of flaws or process related problems can result in significant cost savings. It is the primary evaluation method of many quality control programmes. VT requires good vision, good lighting and the knowledge of what to look for. Visual inspection can be enhanced by various methods ranging from low power magnifying glasses through to boroscopes. These devices can also be used with television camera systems. Surface preparation can range from wiping with a cloth to blast cleaning and
treating with chemicals to show the surface details. It can identify where a failure is most likely to occur and identify when failure has commenced. VT is often enhanced by other methods of inspection which can identify defects that are not easily seen by the eye.
Post Weld Heat Treatment Division
This Division handles the specialized fields of Post Weld Heat Treatment (PWHT) and Pre Heating serving the requirements of the petrochemical
industry. To develop PAK INSPEC’s existing operation in the fields of Post Weld Heat Treatment (PWHT) we are engaged in several training programs for our technicians to gain the satisfaction of our clients.
PWHT is an abbreviation for Post weld Heat Treatment. It is carried out by electrical resistant method or by (furnace firing or internal firing) with high velocity fuel burners. There are three main benefits, stress relaxation, tempering and hydrogen removal. The first two benefits are the generally the reason for the heating operation, with hydrogen removal being considered as a bonus.
PAK INSPEC specializes in providing services to, petrochemical, power fertilizer
heady lifting equipment industries for non-destructive Testing, Inspection,
Expediting and other quality related activities. The company’s activities place
particular emphasis on expertise, experience, capability, reliability and quality. We
believe a high standard of quality in all our services is essential to the achievement
of corporate objectives and the continued growth and success of the company. It is
the company’s intention to provide these services in a manner, which fully meets
client needs and statutory requirements. To achieve this objective, we have

policy is the cornerstone of the company’s Health, Safety and Environmental
Management System (HSEMS). It is communicated openly and at every
opportunity to employees, customers, vendors, and subcontractors and has
equal status with other primary business objectives. Violation of the policy
should be immediately brought to the attention of management.
The company’s philosophy is that, in the performance of our work, the health
safety and welfare of the people involved and the protection of asset and the
environments are primary concern.
We believe accidents are caused, and therefore can be prevented. The safety and
health of employees and subcontractors, accident prevention and environmental
protection is each operating until’s responsibility. Employees at all levels will be
held responsible and accountable for preventing job related illnesses and
injuries, and equipment and environmental accidents through the diligent and
consistent application of the company’s HSEMS. Employee safety performance
will be a major consideration in decision affecting promotions, salary actions and
