07 FAQ
Before we
get started.
Which software do you use?+
Primarily CAESAR II, supported by internally developed engineering and reporting tools.
Which codes do you work with?+
Our core work covers ASME B31.3, ASME B31.1 and ISO 14692, alongside relevant EN standards and project-specific requirements.
Can you support international projects?+
Yes. Axion Engineering is structured to support project teams remotely across regions and time zones.
Can you work as an engineering subcontractor?+
Yes. We can integrate as a specialist external pipe stress resource within an EPC or engineering company's delivery team.
What do you need to prepare a proposal?+
A brief scope, line count or isometric set, design conditions, applicable codes and required schedule are usually enough to begin.
