Steam Turbine Packing & Seals

Steam Turbine Packing & Seals are critical sealing components designed to minimize steam leakage, improve turbine efficiency, and protect internal components in high-temperature, high-pressure steam turbine systems. These precision-engineered parts are widely used in shaft sealing, gland sealing, labyrinth sealing, diaphragm sealing, and interstage sealing applications to ensure reliable operation and maximize power generation efficiency.

At DAWOPU, we manufacture a comprehensive range of steam turbine packing and sealing components for OEM replacement and MRO (Maintenance, Repair, and Overhaul) applications. Our products are engineered according to customer drawings, samples, or OEM specifications, providing excellent dimensional accuracy, sealing performance, and long service life.

Our product range includes Labyrinth Seals, Carbon Seal Rings, Brush Seals, Honeycomb Seals, Gland Packing, Oil Deflectors, Seal Rings, Packing Rings, Packing Segments, Steam Gland Seals, Hydrogen Seal Rings, and Custom Turbine Sealing Components. These products are manufactured using premium materials such as stainless steel, nickel-based alloys, carbon graphite, bronze, PTFE composites, Inconel®, Hastelloy®, and other high-performance sealing materials, ensuring excellent resistance to heat, wear, oxidation, corrosion, and thermal fatigue.

With advanced CNC machining, EDM processing, precision grinding, laser welding, and strict quality control procedures, every sealing component is inspected for dimensional accuracy, surface finish, concentricity, and material integrity. This ensures reliable sealing performance under demanding operating conditions while reducing steam leakage, improving thermal efficiency, and extending turbine service life.

DAWOPU supplies replacement packing and seals compatible with major steam turbine manufacturers, including GE, Siemens, Mitsubishi Power, Toshiba, Hitachi, Ansaldo Energia, Doosan Škoda Power, Elliott, MAN Energy Solutions, and other industrial steam turbine OEMs.
