Radiography and X-ray testing are held for defection surface and interior defects (slags, gas porosoity,micro-cracks, undercuts, slag inclusions) due to the X-ray’s ability to penetrate through the metal and affect the photosensitive X-ray’s film, located at the backside of metal.
Ultrasonic testing is based on researching process of spreading ultrasonic wavering and its reflection from defects and discontinuities in tested products with special equipment. Finding of equipment walls thickness, separate details size measuring, duplex-metal weld overlay thickness, wall losses, which are subjects to wear.
The MPI method is based on the magnetic particle attraction by leakage flux, which appears under defects in magnetized inspection area. DPT is based on capillary penetration of fluids into defects and their contrast displaying, that is used for detection of surface defects.
Heat treatment is heating of detail or area till definite temperature, keeping this temperature and cool down rate. Herewith the change of structure takes place, and consequently the mechanical and technological properties changes of processed area. Hardness test is held for determination of metal’s and alloys qualities, the ability their using in different constructions and under different conditions of work.
The control of cover quality is follow: Visual inspection, Cover’s thickness inspection, Determination of cover’s porosity, Testing of adhesion the cover with basic metal. Demagnetization is the process of material magnetization decrease by impact on magnetic material by alternating magnetic field with decreasing amplitude for welding simplification.
Determination of quantitative characteristic and microstructures of material, static analysis and reports about results of researching, forming of digital images and protocols of researching materials. Determination and control of ferrite’s phase content.
The basis for technical condition during industry safety expertise is diagnostic examination of all construction elements, including bottoms and walls. The recommendations about further operation conditions with probable residual resource, dates and levels of following surveys, necessity of repair or shutdown are issued according to received information
The vacuum testing is the most general method of leakage testing welds on the pressure vessels, using for keeping fluid or gas. The vacuum control is the rather simple way of testing.
Unlike UT which is done in various clock positions on pipelines; LRUT does100% scanning of the pipeline from a single location. It can inspect inaccessible areas like offshore risers & offsite piping, road crossings, dykes, culverts, in-cased pipelines etc. LRUT is used as a screening tool by all of the major Oil and Gas companies for more than 10 years now.
PEC is used for Corrosion Under Insulation (CUI) applications and in this technique thickness measurements can be made through any type of non- metallic coatings / insulations without removal of insulation / coatings. Typical applications are Concrete coated Horton Sphere Legs, Insulated pipelines, brick lined / concrete coated Vessel Skirts etc. PEC can be done online without disturbing the operations at very high and sub-zero temperatures.
It involves detecting, locating and measuring the severity of sources of emissions in structures /equipments. Applications include Inspection of tanks for leaks, corrosion & grading, Inspection of vessels etc. Continuous monitoring of Bridges & Aircraft structures are other applications apart from Oil & Gas sector.
the key to TechCorr’s in-service inspections is our robotic inspection system, a remotely controlled hydraulic robot specifically designed toinspect in-service tank floor bottoms.
MFL is for scanning the Tank Floor for corrosion and pitting during out of service inspections. It is highly productive tool to map volumetric changes in the tank floor to assess the condition & integrity.
Asset Integrity Management (AIM) is the program for the safe and reliable operation of production equipment and facilities. AIM encompasses the minimization and mitigation of environmental, operating, and safety risks through Asset Inspection, Assessment, Compliance and Documentation.
The Automated inspection system is a development of Technology Design. It applies Corrosion Mapping, Time of Flight Diffraction (TOFD), Pulse Echo ultrasonic Testing (PEUT), Zoned Weld Inspection, Phased Array Ultrasonic Testing (PAUT). This technology applies to non-destructively screen piping and vessels, such as those found in the refining and petrochemical industries. The user is provided with a true representation of the test material which speeds the process of defect interpretation.
Tubular Inspection is for the inspection of ferrous and non- ferrous tubes (plain and finned tubes) through Eddy Current Testing (ECT), Remote Field Testing (RFT), DC Saturation Eddy Current Testing, and Internal Rotating Inspection System (IRIS)
