Process Piping Inspection based on ASME B31.3

Process Piping Inspection Course based on ASME B31.3

The Process Piping Inspection Course based on ASME B31.3 is designed to provide in-depth knowledge about the inspection, testing, and maintenance of process piping systems used in industries such as oil and gas, petrochemical, chemical, and power generation. The course focuses on ensuring that piping systems comply with the ASME B31.3 Process Piping Code, which is the primary standard for the design, construction, and inspection of process piping.

Participants will learn about the key inspection procedures, non-destructive testing (NDT) methods, and acceptance criteria required to maintain the safety and mechanical integrity of process piping systems. The course emphasizes both theoretical knowledge and practical skills needed for performing piping inspections, defect detection, and compliance verification based on ASME B31.3.

• Learn the principles of process piping inspection, including visual inspection, NDT methods, pressure testing, and corrosion evaluation.
• Develop the skills to identify common defects in process piping and assess their impact on the integrity of the system.
• Understand the acceptance criteria for piping defects and how to determine if repairs or replacements are necessary.
• Learn how to interpret piping drawings, specifications, and codes to ensure compliance with the ASME B31.3 standard.
• Become familiar with the documentation and reporting requirements for process piping inspections.

4- Inspection Techniques for Process Piping

• Visual Inspection (VT): The most basic and widely used inspection method, identifying surface defects such as corrosion, mechanical damage, and leaks.
• Non-Destructive Testing (NDT) Methods:
  • Ultrasonic Testing (UT): Used to measure the remaining wall thickness of pipes and detect internal flaws such as corrosion or cracks.
  • Radiographic Testing (RT): X-ray or gamma-ray imaging to identify internal defects in welds and piping materials.
  • Magnetic Particle Testing (MT): Used to detect surface and near-surface defects in ferromagnetic materials.
  • Liquid Penetrant Testing (PT): For detecting surface defects such as cracks, leaks, and other discontinuities.
  • Eddy Current Testing (ECT): For detecting flaws in conductive materials without removing insulation.
  • Leak Testing: Hydrostatic and pneumatic testing methods for verifying the leak-tightness and pressure integrity of piping systems.

5- Corrosion and Erosion in Process Piping

• Understanding corrosion mechanisms (e.g., uniform corrosion, pitting, crevice corrosion, and galvanic corrosion) that affect process piping systems.
• Erosion and erosion-corrosion: Inspection techniques for detecting and evaluating the impact of fluid flow on piping surfaces.
• Techniques for monitoring and inspecting for corrosion under insulation (CUI), a common issue in insulated piping systems.
• Corrosion control methods, including coatings, cathodic protection, and material selection.

6- Welding Inspection in Process Piping

• Welding requirements in process piping based on ASME B31.3, including pre-weld inspection, in-process inspection, and post-weld inspection.
• Inspection of weld joints for defects such as incomplete penetration, porosity, undercut, cracks, and excessive reinforcement.
• Non-destructive methods for inspecting welds, including radiographic testing (RT) and ultrasonic testing (UT).
• Understanding welding procedure qualifications (WPS/PQR) and ensuring compliance with ASME B31.3 standards.

7- Pressure Testing and Leak Testing

• Hydrostatic Testing: Conducting pressure tests by filling piping systems with water and pressurizing to check for leaks and verify strength.
• Pneumatic Testing: Using air or inert gas for leak testing in cases where hydrostatic testing is impractical.
• Safety considerations and procedures for performing leak tests on process piping systems.

8- Acceptance Criteria for Piping Defects

• Understanding the acceptance criteria for various defects in process piping, including corrosion, mechanical damage, and weld defects.
• Decision-making process for determining if defects require repair, replacement, or further evaluation.
• How to assess the fitness-for-service of piping systems using the ASME B31.3 criteria.
