Production
Quality Control
Quality comes first at every stage of our production, with no compromise on compliance with international standards. From raw material intake to final dispatch, every step is rigorously inspected by our experienced quality control team.
Testing and Inspection
Proven quality before every dispatch
During production, the weld seam and surface are monitored in real time with ultrasonic equipment.
Pipes are pressure tested with water at specified values to verify resistance to operating pressure.
Weld seams are examined radioscopically in detail according to customer requirements and applicable standards.
Incoming coils undergo dimensional, mechanical and chemical testing, ensuring full traceability.
Inspection Chain
Eight inspection steps from intake to dispatch
Incoming Quality Control
The mill certificate (EN 10204 3.1) of every coil is verified; chemical and mechanical values are confirmed by spectral analysis and tensile testing. Non-conforming material never enters production.
Welding Parameter Monitoring
Current, voltage and travel speed are continuously monitored and recorded along the line; compliance with the approved welding procedure (WPS) is audited every shift.
Online Ultrasonic Inspection
100% of the weld seam is scanned ultrasonically during production; suspect areas are automatically marked for further evaluation.
Dimensional Inspection
Diameter, ovality, wall thickness, length and end squareness are measured on every pipe and reported against standard and specification tolerances.
Hydrostatic Testing
Every single pipe is water-tested at the pressure required by the standard; no pipe proceeds until leak-tightness and structural integrity are verified.
Offline UT and Radiographic Verification
Areas marked during online inspection and the pipe ends are re-scanned with offline ultrasonic equipment; where required, seams are confirmed radiographically (X-Ray).
Coating Quality Controls
On coated pipes, dry film thickness is measured at multiple points, the entire surface is scanned with a high-voltage holiday detector and adhesion (peel) testing is performed.
Final Inspection and Traceability
After final visual inspection, each pipe is marked with standard, diameter, wall thickness and a traceability number. All test records are archived as a report package.
