Product Description
Customized 600MW Steam Turbine Diaphragms
Our custom-engineered 600 MW steam turbine diaphragms are core stationary components for large-scale thermal power generating units. Installed inside turbine casings, they hold stationary nozzle blades, separate pressure stages, guide high-temperature & high-pressure steam flow, and convert steam thermal energy into kinetic energy for rotor rotation.
Diaphragm manufacturing quality directly determines unit heat-rate, generating efficiency and long-term safe & stable operation.
Custom Engineering Solutions
We deliver fully tailor-made diaphragms for 600 MW sub-critical and super-critical turbine units. According to stage pressure, steam temperature-pressure parameters, flow path requirements and installation dimensions, we complete material selection, structural optimization, stationary blade assembly, welding and precision machining.
Our solutions cover new-unit manufacturing, turbine efficiency retrofitting, overhaul spare-part replacement and defect-diaphragm renewal.
Key Features
Grade-matched Heat-resistant Alloy Material
High-strength heat-resistant alloy steel for high/intermediate-pressure stage diaphragm rings and partitions; qualified carbon steel for low-pressure sections. Excellent high-temperature strength, creep resistance, thermal-fatigue and oxidation-resistant performance.
Precision Custom-Engineered Structure & Blade Assembly
Customizable inner-outer ring dimension, stationary-blade airfoil profile, nozzle chamber structure, labyrinth sealing tooth layout and mounting interface. Strictly follow original drawings for spare-part replacement with optimized redesign for flow-path retrofit to upgrade unit efficiency.
Mature Welding & Stress-relieving Treatment
Qualified welding procedures for diaphragm sub-assemblies with stress-relieving heat treatment after welding to eliminate residual stress. Maintains stable radial & axial clearance between diaphragm and rotor, lowering shaft vibration risk.
Comprehensive Quality Assurance System
Each diaphragm undergoes multi-item inspections including non-destructive testing (UT, MT), dimensional accuracy check, blade profile detection and assembly-clearance verification, complying with thermal power equipment industry standards.
Application Scenarios
Specially designed for 600 MW sub-critical / super-critical steam turbine units, suitable for HP, IP and LP cylinder stages. Widely applied for:
  • New thermal power plant construction
  • Turbine flow-path performance retrofit
  • Unit overhaul spare-part supply
  • Damaged-diaphragm replacement
Custom Service
Please provide original drawings, stage technical parameters, operating conditions or failed-part reference. Our engineering team will conduct technical evaluation and deliver targeted technical proposal plus competitive quotation within short lead-time.
