Stainless Steel GOST9941-81 12X18H12T Heat Exchanger Tube In Industries For Power Generation
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.
Chemical Composition:
| Grade | Cr | Ni | Ti | C |
| 12X18H12T | 17.0-19.0% | 9.0-12.0% | ≥ 5x C content | ≤ 0.12% |
Mechanical Properties:
| Grade | Tensile Strength | Yield Strength | Elongation | Hardness |
| 12X18H12T | ≥ 205 MPa (30 ksi) | ≥ 515 MPa (75 ksi) | ≥ 35% in 50 mm | Typically ≤ 95 HRB |
Applications:
Chemical Processing: Used in heat exchangers to facilitate heat transfer in processes involving corrosive chemicals.
Oil and Gas: Employed in heat exchangers for crude oil refining, natural gas processing, and petrochemical applications, where resistance to high temperatures and corrosive environments is crucial.
Power Generation: Utilized in steam boilers and cooling systems, helping to manage heat transfer between fluids in power plants.
Food and Beverage Industry: Used in pasteurization and refrigeration systems, where hygiene and resistance to corrosion are important.
Pharmaceuticals: Applied in processes that require strict adherence to hygiene and material integrity, ensuring safe heat exchange.
Water Treatment: Used in heat exchangers for processes such as desalination or wastewater treatment, where durability and corrosion resistance are vital.
Marine Applications: Employed in shipboard heat exchangers, where exposure to seawater and harsh conditions requires robust materials.
