Inspection areas
Clearly focused. Precisely documented.
Industrial inspections only achieve their full benefits if they are specifically tailored to the system being tested.
At Thor Engineering Services & Expert Office GmbH, we divide our inspection activities into three central areas.
Each of these places particular demands on methodology, equipment technology, and documentation – and this is precisely where our strength lies: in the application of the appropriate test methods and recording systems according to the situation.
→ Pipelines
Pipeline systems are subject not only to mechanical, but also to thermal, chemical and operational loads. Our inspection services ensure that every welded joint, every installation position and every design meets the requirements of norms and safety regulations.
Typical services:
Interior inspections by video endoscopy or driving camera
Documentation of weld seams and joints
Testing for corrosion, cracking, material deformation
Support with commissioning, modifications or revision releases
→ Tanks and Vessels
Whether under pressure, under vacuum or designed for sensitive media - tanks and vessels must be inspected without gaps. Our image-based procedures enable the capture of large internal surfaces, weld seam zones and hard-to-reach areas – with clear visual findings and standard-compliant reporting.
Typical services:
360° interior shots with high-resolution camera systems
Wall thickness measurement, corrosion testing, lining inspection
Video recordings for audit reports & operator obligations
Preparation and support of acceptance tests (e.g. pressure tests)
→ Individual system assemblies
Every assembly has its critical function – and therefore deserves a correspondingly targeted testing. Baugruppe We inspect individual components before assembly, in workshop or when installed – using methods tailored to the material, medium and operating environment.
Typical services:
Visual inspection of components, sealing surfaces, connection areas
Condition monitoring of heat exchangers, valves, filter units
Endoscopic examination of difficult-to-access flow paths
Documentation for acceptance protocols, QA databases, traceability

Structure creates clarity - and trust.
Our clear structure according to inspection areas facilitates the planning, verification and coordination with all project participants.
