CAESAR II is the trusted choice of thousands of engineers and piping professionals worldwide. Whether you are designing a new system, modifying an existing one, or performing a fitness-for-service assessment, CAESAR II can help you deliver your projects on time, on budget and with confidence.

CAESAR II - What is it?
CAESAR II - What is it?
CAESAR II® is stress analysis software used for the mechanical design and analysis of piping systems.
It is a specialized software used by engineers to evaluate the response of piping systems to various types of loads, such as weight, temperature, and pressure in accordance with over 40 international piping codes and standards. C-II helps in calculating the forces, moments, and stresses that a piping system will encounter during operation.
By providing detailed analysis, CAESAR II ensures that the piping systems comply with industry standards and are safe for operation.

How Does CAESAR II Work?
How Does CAESAR II Work?
At a fundamental level, the engineer builds a piping model and inputs the different loads that the system might experience, such as:
Weight: The weight of the piping system itself.
Temperature and Pressure: Changes in temperature and pressure that impact the system.
External Loads: Displacements from equipment connections and other external forces.
CAESAR II processes these inputs and calculates the resulting forces and moments throughout the system. These outputs are then evaluated against the design code limits to ensure they are acceptable. The software helps in checking the following:
1. Stresses: Ensuring they are within the permissible limits defined by the design code.
2. Equipment Loads: Verifying that the loads on equipment connections meet the allowable values specified by standards like API 610 or by equipment manufacturers.
3. Displacements: Ensuring that the pipe movements do not exceed acceptable limits.
Types of Analysis in CAESAR II
Types of Analysis in CAESAR II
With CAESAR II, you can perform static, dynamic and flange analysis while accounting for wind, wave seismic, thermal and pressure loads, as well as weight and support.
So, we can say that CAESAR II is not just limited to static analysis (i.e. weight of the system, temperature, pressure, wind loads, and snow/ice loads); it also performs dynamic analysis, covering a wide range of scenarios including:
Modal Analysis: To calculate the natural frequencies of the piping system, ensuring they are within safe limits to avoid resonance with sources of vibration.
Seismic Analysis: To evaluate the effects of earthquakes.
Relief Valve Analysis: To assess the impact of thrust forces during relief valve operations.
Fluid Hammer Analysis: To evaluate the effects of pressure waves caused by the rapid closing of valves.
Slug Flow Analysis: To analyze the impact of a denser medium moving through the system.
Harmonic Analysis: To assess the effects of harmonically induced vibrations.These analyses are crucial for ensuring the safety and reliability of piping systems in various industrial applications.
