Product Description
GOST 9941-81 refers to the Russian standard that specifies the technical requirements for stainless steel tubes used in heat exchangers. This ensures the tube meets specific performance and safety criteria. Stainless Steel GOST 9941-81 12X18H12T Heat Exchanger Tube is designed for high-temperature and corrosion-resistant applications. This Russian standard stainless steel, equivalent to AISI 321, is stabilized with titanium to prevent carbide precipitation.
These tubes are typically manufactured using methods that ensure a smooth surface finish and uniform wall thickness, which are important for maximizing heat transfer efficiency.
