Corrosion testing

Corrosion - MARV

Corrosion and material degradation are tested and evaluated at our corrosion testing laboratories, at four locations in Europe, the United States and Asia.

Corrosion testing

Corrosion degradation leads to huge costs every year as described in a DNV GL-led study. To help the industry find cost-optimal solutions DNV GL carries out corrosion testing and corrosion evaluations at our corrosion testing laboratories.

Corrosion testing laboratories

DNV GL has specialized corrosion testing laboratories located in the USA (Columbus, OH), Norway (Bergen), Singapore and UK (Loughborough).  

We test both metallic and non-metallic materials, with specialties in harsh environments such as H2S sour service testing and high pressure – high temperature (HPHT). 

Our highly skilled and experienced materials scientists and engineers study a variety of material threats. The corrosion laboratory services cover material and corrosion technology – general and local corrosion, H2S sour service, coating degradation, materials compatibility, stress corrosion cracking, corrosion fatigue, thermal fatigue, creep, high-temperature corrosion, microbiologically-influenced corrosion (MIC corrosion), and fracture mechanics. 

A systematic, rigorous and detailed approach to material science is supported by in-depth knowledge of applicable codes, standards and regulations with state-of-the-art corrosion laboratory and modelling tools. 

Our experts provide material selection and corrosion assessment, recommending mitigation and prevention measures.

Sour service H2S corrosion

For oil and gas pipelines and processing plants sour service H2S containing environments have to be managed to ensure the integrity of an installation. Materials to be exposed in sour environment needs to be qualified for the actual application, if not pre-qualified (ref. ISO 15156/NACE MR 0175).

DNV GL has world-leading expertise in multiple locations around the world for H2S testing including elevated temperatures and pressures.

Coating testing

To obtain and ensure satisfactory standard of the coating in its intended environment, DNV GL is accredited to conduct several standardized coating tests. Customized tests help customers identify the cost-optimal coating system.

Environmentally-induced crack testing

A specific area of expertise is environmentally-induced crack testing. DNV GL has world-leading expertise in Hydrogen Induced Stress Cracking (HISC) and Stress Corrosion Cracking (SCC) testing. We have also developed models for cracking mechanisms and guidelines on how to avoid this.
