Pressure Vessels

A pressure vessel is a container designed to hold either toxic or non-toxic gases or liquids at a significantly higher pressure than the surrounding air pressure. Regular inspections in the demanding industrial environments are a critical part of the maintenance process for pressure vessels, helping to uncover potential problems before they develop further.

Ensuring safety and integrity

Inspections are a crucial part of the maintenance process for pressure vessels. Most regulations include specific requirements for the frequency of these inspections, as well as the use of NDT technology to ensure compliance. Most inspections are performed intrusive by opening the vessels for human access or cover large portions of the surface. Understanding the damage mechanisms, morphologies and rates, the likely location where the damage will occur, and the associated risk, opens up the next level of optimal inspection strategies for pressure vessels by using non-intrusive methods (NII) whenever possible.

Understanding the real challenge for pressure vessels

The industry is subject to several codes and regulations to ensure the safety and integrity of pressure vessels. We help you stay vigilant, by regularly reviewing the condition of affected assets. By developing risk-based inspection (RBI) plans, we provide recommendations on inspections as well as the right interpretation of inspection results.
