Graphitization in Low Alloy Steel Pressure Vessels and Piping

Thermal Stresses in Vessels, Piping, and Components

Process Piping: Polymers Versus Stainless Steel

choice for pharmaceutical industry process systems. Its high mechanical strength and low coefficient of thermal expansion allow components to be sterilised or sanitised using various mediums and at high temperatures. Concerns about stainless steel systems – such as rouging in high purity water, metallic ion contamination and inner surface finishes – which require post-installation maintenance a...

Stainless Steel for High Pressure Piping in SWRO Plants. Are there any Options?

Service experience from 27 seawater reverse osmosis (SWRO) plants confirms that there is an evident risk of corrosion if wrong steel grade is used for the high pressure piping. Neither 316L nor 317L possesses sufficient corrosion resistance. Not even highly alloyed grades like 2205 and 904L show reliable service performance. However, no corrosion has been reported for 254 SMO, which has been us...
