(35d) Effect of Contaminants on Coke Formation during
The coupons were subjected to helium atmosphere during stabilization modes (overnight). The morphology of the coked reactor materials were studied using an off-line Scanning Electron Microscope with Energy Dispersive X-ray (SEM with EDX) images of coked coupons. References.

Hot Tapping - Strategies & Effective Practices to Manage
Switch off Cathodic protection. Cathodic protection can sometimes affect welding operations in pipelines. Ensure the same is switched off. Have a risk assessment done for the complete hot tap job. Maintenance, Inspection and Operations crew on site should meet with the contractor and prepare a risk assessment for conducting the hot tap job safely.
Strategies & Effective Practices to Manage and Mitigate
Higher hardness can also cause problems during drilling of coupons. Maintaining fluid flow during hot tap operations Hot tapping operations are considered safe based on the fact that molten metal during welding solidifies and cools to less than about 400 deg C very quickly.

Multiple polymer coupons of the same material as the sheath are inserted into the flow and then later removed and evaluated. A quantitative analysis estimates the remaining service life of the sheath and determines any changes to the molecular structure or chemical properties that may affect the sheathâs overall strength.
(512f) An Investigation of High-Temperature Corrosion
Past research work on understanding the high temperature corrosion mechanisms has identified important factors that affect the corrosion rate. In addition, there have been many laboratory tests that have sought to classify the effects of these corrosion factors where metal coupons were subject to corrosion at constant furnace temperature.
