Gas Turbine Parts — Hot Gas Path & Cold Section Components
OEM-grade replacement and refurbishment parts for industrial and aero-derivative gas turbines — blades, nozzles, combustor hardware, compressor blading, discs, ring segments and seals, engineered for maximum life and performance.
Gas Turbine Part System — Compressor · Combustor · Turbine
The Hot Gas Path (combustor + turbine section) is the highest-wear area and the core of gas turbine MRO — parts are investment-cast superalloy with internal cooling and thermal barrier coatings.
Hot Gas Path Parts
Combustor and turbine-section components exposed to the highest temperatures — manufactured to OEM metallurgy, cooling geometry and coating specification.
Turbine Blades
Extract energy from the expanding hot gas. Precision investment-cast airfoils with internal cooling passages, film holes and fir-tree roots.
- ✓Equiaxed, directionally solidified or single-crystal superalloys
- ✓Internal serpentine cooling + TBC thermal barrier coating
- ✓Fir-tree root, machined to 0.01 mm interface tolerance
Turbine Nozzles & Vanes
Stationary airfoil rings that accelerate and direct hot gas onto the rotating blades at the optimum angle — the most thermally loaded static parts.
- ✓One-piece or segmented nozzle rings, air-cooled
- ✓TBC-coated with full gas-path coverage
- ✓Matched to OEM vane platform geometry
Combustor Liners
Thin-wall superalloy cylinders that shape and contain the flame. Dense cooling-hole patterns manage metal temperature and maximise combustion life.
- ✓Wiggle-strip, louvered or slot-cooled designs
- ✓High-temperature sheet superalloy, welded assembly
- ✓Repair: crack weld, panel replacement, recoating
Transition Pieces
Curved superalloy ducts that carry hot gas from the combustor liner to the first-stage turbine nozzle, converting flow from circular to annular.
- ✓Formed sheet superalloy with cooling features
- ✓Mounting rails, gaskets and seals included
- ✓Full repair capability: weld, heat-treat, coat
Fuel Nozzles
Atomise and mix fuel with combustion air for stable, low-emission combustion. Precision flow passages and tip geometry are critical.
- ✓Liquid, gas and dual-fuel configurations
- ✓Precision flow-matched to OEM spec
- ✓Cleaning, flow-test and refurbishment service
Turbine Discs
Forged superalloy discs carrying the blade rows, with broached fir-tree slots machined to extreme accuracy for safe blade retention.
- ✓High-strength forged or powder-metallurgy discs
- ✓Broached fir-tree / dovetail slots
- ✓Full NDT: UT, MPI, dimensional verification
Ring Segments & Shrouds
Arc-shaped shroud segments above the blade tips with honeycomb or abradable surfaces that control tip clearance and reduce leakage loss.
- ✓Honeycomb and abradable inner surfaces
- ✓High-temperature alloy with TBC options
- ✓Matched segments for full-ring replacement
Seals — Brush / Honeycomb / Labyrinth
Shaft and inter-stage seals that minimise leakage at clearances, improving efficiency and reducing secondary-air consumption.
- ✓Brush seals with dense metallic filament packs
- ✓Honeycomb and stepped labyrinth configurations
- ✓Drop-in cartridges and retrofit assemblies
Compressor & Rotor Support Parts
速度到压力
Compressor Blades & Vanes
Multi-stage axial rotor blades and stator vanes, plus variable inlet guide vanes, that raise air pressure ahead of the combustor.
- ✓Stainless, titanium and alloy-steel airfoils
- ✓Anti-corrosion and anti-fretting coatings
- ✓5-axis machined, matched to stage aerodynamics
Bearings & Rotor Support
Tilting pad journal and thrust bearings supporting the gas turbine rotor on a pressurised oil film at high speed and load.
- ✓Multi-pad tilting pad journal bearings
- ✓Double-acting thrust bearings with equalisation
- ✓Babbitt-lined, high-speed rated
Metallurgy, Manufacturing & Repair Capabilities
From new replacement parts to full hot-gas-path refurbishment — one responsible supplier for casting, machining, coating and testing.
Manufacturing & Materials
- ▸Investment casting: equiaxed, directionally solidified (DS) and single-crystal (SX)
- ▸Vacuum-induction melting, forged and powder-metallurgy discs
