Inspection starts at the weld seam and ends in the laboratory.
Ultrasonic inspection
The weld seam is checked automatically during production.
Visual inspection
Outer and inner surface of the pipe.
Hydrostatic pressure test
Up to 211 bar, to the applicable standard and project specification.
End inspection
Final inspection of the pipe ends.
Laboratory tests
Mechanical and chemical tests against production parameters.
