Pressure Vessels & Heat Exchangers

Complete Pressure Vessel Design and Verification

We provide engineering services for a wide range of pressure equipment, including:

• Pressure vessels
• Heat exchangers
• Vertical and horizontal vessels
• Knock-out drums and separators
• Water seal drums
• Flare system vessels
• Custom pressurized equipment

Code-Based Design and Verification

Pressure vessel calculations are performed according to internationally recognized design codes, including:

• ASME Section VIII Division 1 and Division 2
• EN 13445 – Unfired Pressure Vessels
• AD 2000
• VSR
• PED – Pressure Equipment Directive

Nozzle Load and Local Stress Analysis

Pressure vessels are often subjected to external loads transmitted by connected piping systems.

Techso Engineering performs detailed nozzle verification, including:

• Nozzle load assessment from piping stress analysis
• Local stress verification according to WRC bulletins
• Reinforcement optimization
• Flange and connection verification

Structural Verification under External Loads

In addition to internal pressure, vessels are verified under external loads such as:

• Wind loads
• Seismic loads
• Equipment loads
• Thermal loads
• Transport and lifting loads

Finite Element Analysis for Critical Components

For complex geometries or critical applications, Finite Element Analysis (FEA) is used to evaluate:

• Local stress concentrations
• Nozzle connections
• Support areas
• Structural discontinuities

PED Compliance and Regulatory Support

Techso Engineering supports clients in achieving full compliance with the Pressure Equipment Directive (PED), including:

• Equipment classification
• Design verification
• Technical documentation support
• Certification preparation
