Shell Turbo Oil T 46
Shell Turbo Oil T 46 is a high-quality industrial turbine oil developed to provide reliable lubrication, extended service life and dependable protection for steam turbines and light-duty gas turbines. Formulated using high-quality hydrotreated base oils combined with carefully selected zinc-free additives, Shell Turbo Oil T 46 delivers excellent resistance to oxidation, strong protection against rust and corrosion and stable lubrication performance in demanding turbine applications. Shell Turbo Oil T 46 builds on the long-standing reputation of Shell Turbo Oils as a trusted industry standard for turbine lubrication across power generation and industrial sectors.
One of the key advantages of Shell Turbo Oil T 46 is its excellent resistance to oxidation and thermal degradation. Turbine lubrication systems typically operate continuously at elevated temperatures and are exposed to air and moisture, which can accelerate lubricant breakdown and deposit formation. Shell Turbo Oil T 46 uses inherently stable base oils combined with an effective inhibitor package to resist oxidative degradation. This helps minimise the formation of corrosive acids, sludge and deposits, supporting extended oil life while helping reduce maintenance costs associated with oil replacement and system cleaning.
Shell Turbo Oil T 46 also provides excellent foam control and rapid air release characteristics. Anti-foam additives within the formulation help control foam formation in turbine lubrication systems, while the oil quickly releases entrained air. These properties help prevent issues such as pump cavitation, excessive wear or premature oil oxidation. As a result, Shell Turbo Oil T 46 helps maintain stable oil circulation and consistent lubrication throughout the turbine system.
Another important benefit of Shell Turbo Oil T 46 is its strong water separation capability. Water contamination is common in steam turbine lubrication systems, and effective demulsibility is essential for maintaining lubrication performance. Shell Turbo Oil T 46 separates water quickly and efficiently, allowing excess water to be easily drained from the lubrication system. This helps minimise corrosion, reduce wear and lower the risk of unplanned maintenance.
Shell Turbo Oil T 46 also provides excellent rust and corrosion protection for turbine components. The formulation protects metal surfaces against rust formation and guards against corrosion even when exposed to moisture or humid environments during operation or shutdown periods. This protection helps maintain the integrity of critical turbine components and contributes to longer equipment service life.
Shell Turbo Oil T 46 is suitable for a wide range of turbine and industrial lubrication applications. Typical uses include industrial steam turbines, light-duty gas turbines where enhanced anti-wear performance is not required, hydroelectric turbine lubrication and centrifugal or axial compressors and pumps where R&O type turbine oils are recommended. Shell Turbo Oil T 46 meets a wide range of recognised industry standards including DIN 51515, ISO 8068 and ASTM D4304 turbine oil specifications.
Physical characteristics include a kinematic viscosity of approximately 46 mm²/s at 40°C and 6.9 mm²/s at 100°C with a viscosity index of approximately 105. Shell Turbo Oil T 46 has a density of approximately 858 kg/m³ at 15°C, a flash point of around 220°C and a pour point of approximately −27°C, supporting reliable lubrication performance across a wide range of turbine operating conditions.
