HGTP Comprehensive Repair Capabilities

At our Hangzhou operations center, we provide full-spectrum solutions for turbine component restoration, combining advanced metallurgy, coating technologies, and precision engineering. Every process is performed in-house under strict quality standards, ensuring reliability for even the most demanding turbine environments.

Specialized Heat Treatment
Our facility is equipped with vacuum furnaces that enable highly controlled heating and cooling cycles. These processes are designed to refine the mechanical and physical properties of alloys, strengthen weldments, and extend the operational life of critical hardware. Applications include pre-weld conditioning, post-weld stress relief, diffusion bonding, and aging treatments tailored to customer requirements.

Protective Coating Systems
We apply high-performance metallic and ceramic coatings that deliver resistance to oxidation, corrosion, and high-temperature attack. Thermal barrier systems are engineered using proprietary materials that minimize metal temperatures and enhance durability. Coating options include APS, HVOF, and other advanced methods for both bond coats and ceramic top coats.

Comprehensive Repair Capabilities
Our repair portfolio covers a wide range of turbine components and advanced processes, including:

• Precision welding (manual TIG, elevated temperature, and laser)

• Brazing for crack repair and material build-up

• Film cooling and tip clearance restoration systems

• Thermal barrier coatings and metallic bond coats

• Advanced NDT and inspection (ultrasonic, CMM, X-ray, FPI)

• Computational modeling to validate life extension strategies

Engineering Integration
Our engineering team collaborates directly with technicians throughout every project stage. Services include non-destructive evaluation, machining, metallurgical analysis, flaw modeling, and detailed quality assessments. Using a three-gate review system, clients remain actively involved in progress checkpoints, which ensures transparency and reduces repair lead times. A comprehensive technical report is delivered at project completion.

Component Coverage
We service a wide variety of hot gas path and steam turbine hardware, such as:

• Buckets, blades, and vanes

• Nozzles, rings, and air seal systems

• Combustion liners and fuel injectors

• Steam turbine diaphragms and valve components

• Shroud tiles, blocks, and other critical assemblies

By integrating advanced technology with engineering expertise, our Hangzhou facility helps turbine operators reduce downtime, control maintenance costs, and achieve long-term operational reliability.
