Non-destructive testing (NDT): visual, radiographic, ultrasonic, magnetic particle, penetrant, leak testing. Positive material identification (PMI).Thickness measurements.Determination of delta ferrite content. Post weld heat treatment (PWHT).
LLC Metesta provides NDT services for more than 15 years in the energy, oil, chemical, logistics, construction sectors in Europe and beyond.
Geography of works include Northern countries – Norway, Sweden, Finland, Bulgaria at south and Benelux at west. The most faraway projects we performed at Martinique and La Réunion.
Specialists are certificated according to EN ISO 9712 standard and Pressure Vessels Directive 2014/68/EU. A Quality Management System is implemented in the company according to the EN ISO IEC 17025 standard since 2007 and is accredited to determine defects of all groups of potentially dangerous equipment, structural steel and weld joints by means of non-destructive methods - visual (VT), radiographic (RT), ultrasonic (UT), magnetic particle (MT), penetrant (PT) leak testing (LT) and to perform ultrasonic thickness measurements of metallic and non-metallic materials.
Ultrasonic phase cell and TOFD (Time-of- Flight Diffraction) are automated or semi-automated ultrasonic testings.
Gamagraphic thickness measurements - measurements of pipelines wall thickness, while pipeline is under operation, without taking off insulation.
Hardness measurement –hardness measurements of welded joints using mobile measurement devices.
Post weld heat treatment of welded joints (PWHT) – improvement of metal properties using thermal effect.
Positive material identification (PMI) - within only a few seconds we are able to identify and analyze up to 70 chemical elements in metal with mobile optical emission spectrometer.
Determination of delta ferrite content in austenitic steels - determination of delta ferrite content in austenitic materials and welded joints.
Welding supervision - we are carrying out welding supervision in construction projects and structural steel factories. We coordinate and supervise welding processes. Plan and provide NDT and prepare technical hand – over documentation. Technical maintenance of metal constructions and other products.
