• الاختبار بالموجات فوق الصوتية (UT) – Detects internal defects in the weld seam.
• Radiographic Testing (X-ray) – Used for critical applications requiring 100% weld inspection.
• Magnetic Particle Testing (MT) – Identifies surface cracks and imperfections.

5. Dimensional & Visual Inspection

• Pipe diameter, wall thickness, and roundness are checked for accuracy.
• Visual inspection ensures no visible defects, dents, or surface irregularities.

6. Surface Preparation & Coating

• يتم تنظيف الأنابيب باستخدام sandblasting or shot blasting لإزالة الصدأ والملوثات.
• Protective coatings (FBE, 3LPE, 3LPP, Coal Tar Epoxy) are applied for corrosion resistance.
• Coating thickness and adhesion are tested to meet DIN and ISO standards.

7. Final Inspection & Packaging

• الأنابيب marked, labeled, and bundled for shipment.
