electric equipment

The steam turbine is the largest power generation unit in my country, and it is widely used in power plants. Safe operation to ensure power generation is an important task of power plants. At present, problems such as steam turbine damage, emergencies, water erosion caused by long-term service, blade cracks caused by fatigue and stress, and air leakage in the cylinder block are often encountered. The blade materials are mostly 1Cr13, 1Cr12, 17-4PH. my company The IMR600 series soft alloy anti-corrosion coating materials and the IMR800 series hard-faced alloy anti-water corrosion coating materials and application methods have been developed, which are being widely used in the surface protection of the final stage blades of steam turbines. There is a unique repair process for the damage to the rotor shaft diameter and the damage to the blade to ensure the safe operation of the equipment.

Our company has developed IMR600 series soft alloy anti-corrosion coating materials and IMR800 series hard-faced alloy anti-corrosion coating materials and application methods, which are being widely used in the surface protection of steam turbine secondary and final blades. There is a unique repair process for the damage repair of the blade to ensure the safe operation of the equipment.

Girdle damage repair

Shaft diameter repair

The shaft head of the Austrian steam turbine of Huanren Power Plant was broken and repaired by laser profiling (now called 3D printing technology).

Other repair equipment also includes the repair of partitions, cylinder blocks and valves. The recently repaired equipment includes the high-pressure main valve of the Russian-made 800MW unit of Suizhong Power Plant and the online repair of corrosion damage of the nuclear gate valve of Shenzhen Daya Bay Pipeline. Our company has the conditions for on-site repair welding, and adopts a unique process of micro-arc deposition of ESD, which does not produce cracks after welding, and local repair welding.
