SS316 is the preferred quality for purposes from cryogenic temperatures to 800F provider.
Along with the metal and design and style of the expansion joint, the nature and focus of the corrosive materials should even be considered. Such as, some components may well lead to localized corrosion or pitting in certain metals.
Burst screening: Burst screening is a harmful testing approach that requires pressurizing the metal bellows and expansion joints right up until they are unsuccessful. This is certainly carried out to find out the utmost force which the products can endure prior to failure.
