Design of Industrial Pressure Piping to ASME B31.3 - Practical Examples

After participating in this course, you will be able to:

• Apply the design-related requirements of the ASME B31.3 Code to industrial pressure piping systems.
• Determine key design parameters such as pressure, temperature, and component selection based on system requirements.
• Utilize simple theories and calculations to assess forces acting on piping system components and ensure structural integrity.
• Perform critical calculations for wall thickness, flexibility, and hydrostatic tests to demonstrate compliance with ASME B31.3.
• Evaluate piping designs to ensure they meet sustained and displacement stress criteria for safe operation.

Description
Industrial pressure piping systems are integral to various industries, including pulp and paper, petrochemicals, mining, and metals. These systems must be designed to withstand harsh operating conditions and comply with stringent regulations. A thorough understanding of the ASME B31.3 code is essential to ensure these piping systems are efficient and safe.

Focusing on the design requirements outlined in ASME B31.3, this course provides practical examples and hands-on exercises to guide participants through the complexities of industrial piping design. You’ll learn how to define critical design parameters, such as pressure and temperature, perform calculations for internal pressure, and determine the appropriate supports and anchors for your system. The course will also cover the design of pipe elbows, openings (branches), and hydrostatic test pressures, with real-world scenarios to reinforce these concepts.

By the end of the course, you will have the skills to confidently design and assess pressure piping systems according to ASME B31.3 standards. You will also learn to evaluate modifications to existing piping systems, ensuring compliance with the latest industry codes and safety requirements.

Note: Training is based primarily on Chapter II of ASME B31.3.
