Quality management
Focus on welding technology, piping and tank construction.
Industrial quality is no coincidence - it is the result of structured processes, professional monitoring and consistent implementation.
At Thor Engineering Services & Expert Office GmbH, the focus of quality management is on the inspection, monitoring and documentation for pipelines, pressure vessels, tanks and their welded joints as well as coating. Our expertise is based on many years of experience on demanding industrial projects – nationally and internationally.
We know the technical, normative and practical requirements for manufacture and operation of welded systems. Whether in new construction, renovations, or operations – we ensure quality before defects occur and we arrange traceable documentation.
