Servises
Calibration and cleaning of pipelines
We provide a range of pipeline cleaning services using our own equipment designed to meet the specific requirements of pipeline operators.
Comprehensive in-line inspection (ILI)
We detect pipeline defects using modern equipment and various methods: ultrasonic (UT), longitudinal magnetization (MFL), transverse magnetization (TFI), electromagnetic-acoustic conversion (EMAT).
Navigation survey and spatial positioning
ZOGPI's platform-free inertial navigation system (INS) collects data on the spatialization of anomalies and the geometry of the main pipeline axis.
Report on the results of in-line diagnostics
Comprehensive data analysis and detailed defect identification helps companies optimize costs, improve reliability and asset integrity during pipeline operations.
Design and manufacture of purification and diagnostic devices
We design and manufacture cleaning equipment of various diameters as well as flaw detectors of different method and size
Additional defectoscopic inspection (ADC)
We conduct additional control in order to assess the convergence of actual defect parameters with the results of the technical report
Production of polyurethane products of any complexity
We manufacture polyurethane products using high-performance resins, hardeners and additives, of any complexity, strength and shape according to individual orders.
Mathematical calculations for predicting the technical condition of the pipeline
We provide a professional assessment of the serviceability of the pipeline. We prepare data on the timing of emergency defects and precise recommendations for their elimination.
We offer customized and optimally cost-effective solutions to meet your needs
