| High Light | Customized Steam Seal Carrier ，Precision CNC Machined Turbine Part ，Stellite Hardfaced Steam Turbine Component | ||
Steam seal carrier (also known as diaphragm carrier or steam seal housing) is a core stationary component inside steam turbines. It is used to install labyrinth steam seal strips, forming a multi-stage sealing structure between rotor and stator. The assembly effectively suppresses steam leakage between stages, improves internal steam efficiency, reduces heat loss, and guarantees safe and economical operation of turbine units.
We provide full customized manufacturing services of steam turbine steam seal carriers for power generation and industrial steam turbines. Products include split-type arc segment steam seal carriers and integral circular seal housings. Supported processes include free forging, ring rolling, precision CNC machining, and optional Stellite hardfacing on sealing surfaces. We strictly follow customer drawings and power industry standards for production, applicable to new unit manufacturing and spare part replacement for overhaul projects.
25Cr2MoV, 42CrMo, 12Cr1MoV, alloy cast steel, stainless steel and other heat-resistant steels matched for different temperature & pressure parameters.
| High Dimensional Precision | Precision five-axis CNC machining ensures accurate groove spacing, flatness, circularity and hole position tolerance. Perfect fit for labyrinth seal strips to avoid assembly clearance deviation. |
|---|---|
| Stable Material Performance | Qualified forgings with standardized heat treatment. Uniform mechanical properties, strong resistance to high temperature, thermal deformation and vibration load under long-term operating conditions. |
| Flexible Customization | Fully customized according to customer drawings: different sizes, segmentation schemes, groove types, mounting structures. We support new part production and optimized retrofit for old turbine units to lower steam leakage. |
| Optional Surface Reinforcement | Stellite cobalt alloy hardfacing service can be provided on friction and sealing surfaces to enhance erosion resistance and extend service life. |
| Strict Quality Traceability | Complete raw material certificates, heat treatment records, machining inspection reports and non-destructive testing documents can be supplied. Comply with ISO, DL/T and related power industry specifications. |
