Piping Inspector API 570

Job Overview

Piping Inspection Execution

• Inspect process piping systems for:
• **Wall loss**
• – internal corrosion, erosion, and flow-accelerated corrosion (FAC)
• **Corrosion Under Insulation (CUI)**
• – especially on carbon steel and low alloy lines
• **Mechanical damage**
• – dents, gouges, cuts, and deformation
• **Cracking**
• – fatigue, stress corrosion cracking (SCC), and thermal fatigue
• Perform external visual inspection of piping circuits, including pipe supports, hangers, and guides.
• Identify dead legs, stagnant zones, and other high-risk locations for corrosion.

Documentation & Record Review

• Review piping isometrics, P&IDs, and inspection history records.
• Verify line numbers, material specifications, design conditions, and service fluids.
• Cross-reference inspection data with previous records to identify trends.

NDT Witnessing & Acceptance

• Witness and accept NDT inspections including:
• **UT Thickness**
• – spot readings, profile scans, and C-scan mapping
• **Radiography (RT)**
• – film interpretation for welds and corrosion
• **Visual (VT)**
• – for surface defects, fit-up, and coating condition
• Ensure NDT techniques, equipment, and personnel certifications meet code and client requirements.
• Review and accept NDT reports with sign-off authority.

Repair & Alteration Oversight

• Review and approve piping repair/alteration procedures including:
• Weld repair procedures (WPS/PQR)
• Installation of repair sleeves or clamps
• Pipe replacement scopes
• Verify post-repair NDT and pressure testing (hydrotest/pneumatic) when required.

Corrosion Assessment & Remaining Life

• Calculate corrosion rates using historical thickness data.
• Determine remaining life and recommend:
• Next inspection dates and intervals (per API 574)
• Inspection methods and locations for future campaigns
• Identify piping circuits requiring RBI (Risk-Based Inspection) reassessment.

Non-Conformance & Quality Control

• Issue non-conformance reports (NCRs) for:
• Non-compliant inspection findings
• Substandard repairs or unacceptable damage
• Missing or incorrect documentation
• Follow up on NCR close-out and verify corrective actions are implemented.

Mandatory Certification

• **Valid API 570**
• (Piping Inspector) certification – mandatory and active.

Experience

• Minimum
• 5 years
• of piping inspection experience in
• oil & gas / petrochemical
• industry.
• At least
• 2 years
• of experience in
• in-service piping inspection
• (corrosion monitoring, CUI, damage mechanisms).
• Experience with
• new construction piping
• (witnessing hydrotest, NDT, and final sign-off) is an advantage.

Technical Knowledge

• **ASME B31.3**
• – Process Piping (design, fabrication, inspection, testing)
• **API 571**
• – Damage mechanisms affecting piping (CUI, HIC, SCC, etc.)
• **API 574**
• – Inspection practices for piping systems
• **API 578**

Qualifications

• **API 580 / 581**
• – Risk-Based Inspection
• **CSWIP 3.1 / AWS CWI**
• – Welding Inspector
• **ASNT NDT Level II**
• in UT or RT
• **IRATA Rope Access Level 1 or 2**
