Assessment of sigma phase embrittlement in austenitic stainless steels such as Type 304H, commonly used in fluid catalytic cracking (FCC) units. Other austenitic stainless steels used in other refining process units are also discussed. The detection and measuring of the amount of sigma phase were made using metallography.

A Recent Case Of Intermetallic Precipitations In Super Duplex

Product Number: 51322-17627-SG

Production of oil and gas is well known to cause potential corrosion issues due to the CO2 content in the well stream. Carbon steel is widely used for production facilities as e.g. flowlines and manifolds, however, aging of the reservoir increases the number of corrosive agents, such as e.g. CO2, which are known to cause high corrosion rates in carbon steel. Therefore, carbon steel piping is often being replaced with super duplex stainless steel due to its high strength, excellent toughness and good corrosion resistance. Replacing carbon steel with super duplex has been conducted on several mature offshore oilfields in the European North Sea region.

Field Metallography and Replication on Liquefied Natural Gas Assets: Non-Destructive Metallurgical Testing to complement other regular Non-Destructive Tests

Product Number: 51320-15140-SG

During plant shutdown maintenance, some components cannot be removed out of service immediately for metallurgical examination due to high cost involved and loss of production hours. The best alternative is to replicate the lab based metallography work under the field conditions. Field Metallography and Replication (FMR) also known as in-situ metallography is a powerful non-destructive test (NDT) tool used to examine the microstructure of the component when it is still in service. Moreover, FMR is also used to study the microstructural alterations for the fitness for service assessment.

This paper provides case studies of materials in Natural Gas Processing facility where FMR was used as an NDT tool without sectioning the component. This paper discusses the damage mechanisms such as sigma phase embrittlement, stress relaxation cracking and creep.
