Сòòò½APP’s range of fracture mechanics and fracture toughness testing services for all environments help you accurately estimate and prolong component lifespan, reduce costly repairs andimprove designs. Leveraging years of experience in testing for the energy sector, coupled with state-of-the-art laboratory facilities, our experts can also conduct fracture toughness tests in highly corrosive environments, including elevated and sub-ambient temperatures, providing results that closely mimic actual material behaviour in real-world use.

 

Fracture Toughness Testing vs Fracture Mechanics Testing – what’s the difference?

Fracture toughness testing measures a material's resistance to crack propagation, helping to determine the point at which a crack in your material will grow uncontrollably and cause failure in service. In comparison, fracture mechanics testing broadly evaluates your material's behaviour in the presence of cracks. It involves studying how cracks start, grow, and propagate under various conditions and stress scenarios.

By performing both fracture toughness and fracture mechanics testing, you can ensure that materials possess the necessary resistance to crack propagation (fracture toughness) and will behave predictably under various stress conditions (fracture mechanics). This combined approach leads to the development of safer, more reliable materials and structures.

Specialized Fracture Toughness Testing for Sour Service Environments

Сòòò½APP provides specialized testing services designed for challenging environments, such as sour service, with a focus on the oil and gas industry. Pipelines and equipment in this sector are often exposed to corrosive gases and liquids. With extensive experience in corrosion testing and advanced laboratory facilities, we perform in-situ fracture toughness tests under highly corrosive conditions, accommodating both elevated and sub-ambient temperatures. Our dedicated sour service fracture toughness testing includes designing and characterizing test procedures specifically for carbon steels and corrosion-resistant alloys, guaranteeing reliable and appropriate data essential for Fitness For Service (FFS) and Engineering Critical Assessment (ECA) analyses. 

 

Reduce costly repairs 

Сòòò½APP’s fracture toughness and fracture mechanics testing helps reduce spending by offering in-depth analysis and understanding of material behaviour under diverse conditions. By identifying potential weaknesses and failure points in materials, our experts help you make proactive improvements in design, reducing the likelihood of unexpected failures. This early detection and correction of flaws prevent failures that would otherwise lead to expensive repairs and downtime. Additionally, our custom testing analyses cater to specific applications, ensuring materials are suitable for their intended use, which enhances overall product reliability and longevity. By accurately estimating your component lifespan and optimizing maintenance schedules, we can help you avoid unnecessary replacements and extend the operational life of your equipment, reducing costs.
