LQCEM is an organizational unit within the LQCEM – Serbian KKOM (Quality control of equipment and materials) Department, HIP–Azotara d.o.o. Pančevo, with 30 years of experience in solving problems of equipment and material in the chemical, petrochemical, petroleum industry and energy industry. The laboratory is accredited as per SRPS ISO/IEC 17025:2006, accreditation no.: ATS no.01-210 for the following methods of non-destructive testing (NDT) and corrosion testing and materials protection:

APPLYING THE SPECIAL PROCEDURES AND METHODS OF NON-DESTRUCTIVE TESTING (NDT)

  • Visual examination
  • Penetrant testing
  • Ultrasound testing: material thickness, defective materials (porosity, gaseous bubbles, dross inclusions, cracks…)
  • Magnetic particle tests
  • Vacuum impermeability testing
  • Hardness testing (using portable device)

PERFORMING RESEARCH ACTIVITIES COVERING CORROSION TESTING AND MATERIAL PROTECTION

  • Environmental corrosion testing, testing the corrosion resistance of materials, corrosive destruction mechanism and protection methods – recording anodal polarization curve
  • Gravimetric testing of general corrosion rate
  • Liquid oil gases corrosion testing
  • Metallographic testing of material, corrosive destruction type, identification of heat treatment and material
  • Testing the content of ferrite in austenitic structure of materials
  • Testing of the quality of the cover layer by measuring the layer thickness
  • Testing of the quality of the lining by measuring the lining thickness
  • Testing the meteorological conditions (temperature and relative humidity) at applying the cover layers or lining

Besides the above accredited testing methods, QCEM also performs and supervises the following:

  • Material heat treatment technology
  • Chemical cleaning technology, equipment and material preservation
  • Technical conditions for the production of spare parts
  • Technology of anticorrosive protection by cover layers and linings
  • Technology of material welding
  • Stable vessels pressure testing

We also produce testing programs prior to material and equipment testing, if required by the contractor. Also, based on the test results, we produce reports, comments, opinions, recovery programs, studies,…(causes, conclusions, problem solving recommendations, functionality prognosis,…)
