Stress Analysis

Techso Engineering provides advanced stress analysis services for piping systems and mechanical equipment, ensuring structural integrity, operational reliability, and full compliance with international design codes.

Stress analysis is a critical engineering activity for industrial plants, particularly in oil & gas, energy, petrochemical, and process facilities, where piping systems are subjected to complex load conditions including pressure, temperature variations, weight, and external forces.

Our engineering approach ensures that piping systems operate safely throughout their entire design life while preventing overstress, excessive displacements, and load transfer to connected equipment.

Complete Piping Stress Analysis

We perform complete stress analysis for:

Process piping systems
Utility piping networks
High-temperature lines
Flare systems
Pump and compressor connected lines
Skid-mounted piping systems

The analysis evaluates all relevant load cases, including:

Sustained loads (weight, pressure)
Thermal expansion loads
Occasional loads (wind, seismic)
Operating and shutdown conditions
Transport and lifting conditions (for modular systems)

This ensures full compliance with allowable stress limits and system flexibility requirements.

Equipment Nozzle Load Verification

One of the key objectives of stress analysis is to control loads transferred to connected equipment, such as:

Pressure vessels
Heat exchangers
Pumps
Compressors
Flare stacks

We verify nozzle loads according to applicable standards and vendor allowable limits, ensuring protection of critical equipment and preventing mechanical failures.

Advanced Analysis Tools

Stress analysis is performed using industry-leading software, including CAESAR II, Autodesk Inventor Nastran, and Finite Element Analysis tools for local verification. These tools allow accurate simulation of piping behaviour under all operating conditions and provide detailed evaluation of:

Stress levels
Displacements
Support loads
Equipment loads

Pipe Support Engineering

Based on stress analysis results, we define:

Support locations
Support types (rigid, spring, guide, anchor, etc.)
Support loads

Proper support design ensures controlled system movement, vibration reduction, and long-term reliability.

Integration with Plant Design and Structural Engineering

Stress analysis is fully integrated with:

3D plant modelling
Structural engineering
Equipment design
Modular skid engineering

This ensures that the piping layout, support structures, and connected equipment operate as a complete and optimized system.

Deliverables

Typical stress analysis deliverables include:

Stress calculation reports
Stress isometrics
Support load tables
Equipment nozzle load reports
Support location drawings
Recommendations for design optimization
