Subsea pipelines 和 equipment used in the oil & 气体 industry are often exposed to complex environmental conditions including sour service 气体 和 liquids, such as wet H2S in combination with various levels of CO2. This causes deterioration to pipelines 和 creates enormous industry-wide challenges in predicting 和 preventing potential pipeline cracking 和 failure.
Although there are well-stablished methods for fracture toughness testing one of the challenges the oil 和 气体 industry faces is the lack of specific material data 和 knowledge on the behavior of pipeline materials under sour service conditions.
im体育APP combines years of experience in corrosion testing for the energy sector with state-of-the-art laboratory testing 和 simulation facilities to perform in-situ fracture toughness tests in highly corrosive environments including elevated 和 sub-ambient temperatures. These tests will give you results closer to the real material behavior in the application.
Dedicated sour service fracture toughness testing
We can design 和 characterize dedicated test procedures for fracture toughness behavior of carbon steels 和 corrosion-resistant alloys in sour service. This guarantees reliable 和 appropriate data, a critical input parameter for your Fitness For Service (FFS) 和 工程 Critical Assessment (ECA) 分析.
Our fracture toughness 和 fatigue testing provides you with highly relevant materials data for the determination of allowable level of defects in pipelines 和 other equipment used in sour service environments:
- Mechanical fracture toughness J-R 和 CTOD curves on SENT, SENB 和 CT specimen
- Fatigue Crack Growth Rate on SENB 和 CT specimen
- Slow Strain Rate Tensile
结果会有帮助, improve your design to reduce the likelihood of future failure, 和 save you time 和 money.
im体育APP优势
From test results 和 data under realistic service conditions, we can carry out ECA 和 FFS 分析 to confirm the capability of a component in sour service environment to provide the expected service even in the presence of flaws.
