Visual inspection of welded connections
By David Sear | 21 December 2020
When we think of welding inspection, visual inspection probably is the most underrated, and more often misused of all methods. We may think it’s fast and straightforward, therefore, easy to mistake, but things aren’t that way. Although it doesn’t need a piece of sophisticated equipment to inspect a welding connection, this doesn’t take from the importance and high results of this method.
HISC analysis in the subsea oil and gas industry
By David Sear | 14 December 2020
Historically, small amounts of duplex and super duplex stainless steel subsea components such as piping and valves have failed due to hydrogen-induced stress cracking (HISC) corrosion1,2. These failures are significant in terms of loss of asset, loss of production, and negative effects on health, safety, and environment (HSE) such as environmental pollution. Therefore, it is extremely important to carry out research into the cause of these failures.
Mediating leakage in clad-steel pressure vessels
By David Sear | 07 December 2020
With the application of pressure vessels in such notable industrial segments such as oil and gas, and chemical and petrochemical the risk of corrosion is heightened.
