Precision Quality Control & Inspection

Because seamless pipes are often used in critical safety applications, our "Super Quality" protocol is the core of our operation. All products are delivered with full traceability and MTC EN 10204 3.1 certification.

Our Inspection Framework Includes:

Continuous Ultrasonic Testing (UT): Full-body automated UT scanning to detect internal flaws, laminations, or wall thickness variations.

Eddy Current Testing (ET): High-speed surface inspection to identify even the smallest external cracks or defects.

Hydrostatic Pressure Testing: Every pipe is tested to specified pressures to guarantee structural integrity under load.

Magnetic Particle Inspection (MPI): Applied to pipe ends and critical surfaces to ensure a perfect finish.

Physical & Chemical Verification: On-site laboratory testing for chemical heat analysis and mechanical properties (Yield, Tensile, and Charpy V-Notch Impact testing).
