فشل الاختبار والإصلاح - Test Failures & Material Defect Rework
Definition
Per [2], 'root cause of valve failure in UAE (corrosion from coastal salt, heat from desert climates).' Per [2], material selection involves 316 stainless steel (15% premium, doubles lifespan) vs. 304 SS, and Hastelloy (40% premium). Per [3], 'material of all valves and accessories shall be free from scale, lamination, inherent corrosion and any other defects.' Per [2], ASTM G48 500-hour salt spray tests for coastal projects and 2000-hour UV aging are mandatory. Test failures require rework: strip, retreat, re-test (2–4 week cycle). Failed batches either scrap (total loss) or re-work (50% margin erosion).
Key Findings
- Financial Impact: AED 80,000–250,000 annually (breakdown: 5–15% batch failure rate × AED 30,000–50,000 per batch rework = AED 50,000–150,000; scrap loss = AED 30,000–100,000).
- Frequency: Per batch (monthly to quarterly; seasonal spike in summer heat/salt corrosion).
- Root Cause: Incorrect material specification for climate/application, inadequate surface treatment process control, supplier variation in raw materials, inadequate pre-production material inspection.
