Case Study: Steam Turbine Overhaul & Repair

The Shandong Kaihua Biomass Thermal Power Plant has been operating a 6MW condensing steam turbine (4.9 MPa/470°C) since 2007. After more than 15 years of continuous operation, the turbine experienced efficiency degradation and increased downtime, resulting in annual revenue losses of nearly $300,000.

• Conducted complete NDT inspections (ultrasonic UT, magnetic particle MT, hardness testing, metallographic analysis).
• Manufactured and replaced critical components (blades, seals, diaphragms) using ISO-traceable materials (Cr-Mo-V steel).
• Applied heat treatment + welding repair to restore structural integrity.
• Performed dynamic balancing and shaft alignment to minimize vibration.
• Completed overhaul in 8 weeks, 40% faster than industry average.

"GOINE restored our turbine's performance beyond OEM standards. The transparency of their ISO-traceable process made every step visible and reliable." - Chief Engineer, Kaihua Biomass Plant

Integrated EPC design inputs enable rapid response to project needs, achieving full-process optimization from concept to engineering package.

Case Study: Design & Engineering

A Thai biomass IPP required a new high-efficiency turbine design but lacked OEM design data. Their existing 6MW turbine showed 15% efficiency loss, costing $400,000 annually.

"GOINE's engineering team gave us a turbine design that exceeded OEM efficiency. Their transparent R&D and patent-driven innovation convinced us to expand cooperation."

In the Shandong Belt and Road biomass project, we incorporated European R&D input to design a 7.2MW high-efficiency turbine, optimizing flow paths and parameters to achieve 38.5% thermal efficiency. This helped the customer meet government PPA output targets, delivering the design package 3 months ahead of schedule and saving 20% in costs.

Custom fabrication specializes in precision manufacturing, component repair, and turnkey solutions for turbine parts. Including custom turbine fabrication, precision turbine manufacturing, turbine component repair, turnkey turbine solutions, CNC turbine machining, EDM turbine parts, heat treatment turbine, and NDT component testing.
