Turbine Oil ISO VG 46 L-TSA | 200L

Sinopec L-TSA Turbine Oil ISO VG 46. Turbine systems demand a lubricant that performs reliably over long service intervals without intervention. The L-TSA 46 is the most widely specified turbine oil viscosity grade, formulated for steam, gas and water turbines where extended oxidation life, reliable water separation and clean system operation are essential. With an oxidation stability of over 2,000 hours (ASTM D943) and RPVOT of 400+ minutes, this is an oil built for continuous industrial service. Approved by GE, Siemens and Alstom Power.

The 200L drum is the standard supply format for turbine lubrication — suitable for initial fills, top-ups and scheduled oil changes in industrial power generation and marine applications.

Key Features

• Strong oxidation stability — Over 2,000 hours ASTM D943 and RPVOT of 400+ minutes at 150°C, delivered by zinc-free additives and inherently stable base oils — extended oil life with minimal acid and deposit formation.
• Positive water-shedding — Robust demulsibility ensures rapid separation of water contamination common in steam turbines, keeping the lubrication system clean and components protected.
• Reliable air release — Fast air release at 50°C and effective antifoam performance maintain optimum oil film thickness and protect against air entrainment under operating conditions.
• Comprehensive corrosion protection — Strong rust and corrosion inhibitors protect equipment during both operation and shutdown periods, extending bearing and component life.
• Broad application suitability — Suitable for circulating systems, anti-friction bearings, enclosed gears and hydraulic units where antiwear additives are not required.

Applications

Sinopec L-TSA ISO VG 46 Turbine Oil is recommended for steam turbines used in industrial power generation, large and moderate marine steam turbine propulsion machinery and associated auxiliary equipment, industrial gas turbines and water turbines. Also suitable for circulating systems, anti-friction bearings, enclosed gears and hydraulic units where there is no requirement for antiwear additives. The ISO VG 46 grade is the most commonly specified viscosity for general industrial turbine applications in the UK.

Also available in ISO VG 32 and ISO VG 68.
