ASME B31.3 Calculation Services: A Comprehensive Guide by Little P.Eng. Engineering

Process piping systems play a crucial role in various industries, ensuring the safe and efficient transportation of fluids and gases. Compliance with industry standards is essential to guarantee the integrity and reliability of these systems. Among the recognized standards, ASME B31.3 stands out as a comprehensive guide for process piping design and construction. When it comes to precise calculations and analysis based on ASME B31.3, Little P.Eng. Engineering offers professional services that help ensure compliance with the standard's requirements.


ASME B31.3 is a widely recognized standard for process piping design and construction. It provides guidelines for the design, analysis, fabrication, installation, inspection, and testing of process piping systems. The standard covers various aspects such as materials, pressure design, flexibility analysis, supports, and more.

As a licensed professional engineer (P.Eng.) specializing in engineering services, "Little P.Eng." can offer several calculation services related to ASME B31.3. These services may include:

  1. Pressure Design Calculations: Little P.Eng. can perform pressure design calculations to determine the maximum allowable working pressure (MAWP) and minimum required thickness for process piping systems. This involves considering factors such as material properties, temperature, corrosion allowances, and design pressure.

  2. Flexibility Analysis: The engineer can conduct flexibility analysis to ensure that the piping system can accommodate thermal expansion, contraction, and other movements without overstressing the components. This analysis helps determine the required pipe supports, expansion joints, and the selection of appropriate piping configurations.

  3. Pipe Stress Analysis: Little P.Eng. can perform pipe stress analysis to evaluate the stresses induced in the piping system under various operating conditions, including pressure, temperature, and external loads. The analysis ensures compliance with the allowable stress limits specified in ASME B31.3 and helps identify potential failure points.

  4. Support Design: The engineer can design pipe supports and hangers based on ASME B31.3 requirements. This involves determining the type, size, and location of supports to ensure proper load distribution, minimize stress, and maintain the integrity of the piping system.

  5. Material Selection: Little P.Eng. can provide guidance on material selection for process piping systems, considering factors such as process conditions, fluid properties, compatibility, and code requirements specified in ASME B31.3.

It's important to note that "Little P.Eng." is a fictional name you provided, and in reality, you would need to consult with a qualified professional engineer who is licensed in your jurisdiction to provide these calculation services based on ASME B31.3.


Pressure Design Calculations:

One of the key aspects covered by ASME B31.3 is pressure design calculations. Little P.Eng.
