Product Description
Custom-Built 1000MW Steam Turbine Gland Sealing Rings
Our custom-manufactured gland sealing rings are critical sealing components for 1000 MW ultra-supercritical large-capacity thermal power steam turbines. Installed between rotating rotors and stationary diaphragms or turbine casings, they adopt labyrinth tooth structure to limit steam leakage across shaft and diaphragm gaps. By cutting steam bypass loss, they effectively improve turbine stage efficiency, reduce unit heat-rate, suppress steam-excited rotor vibration, and ensure safe, stable and economical operation for 1000 MW power-generating units.
We deliver fully tailor-made sealing rings for 1000 MW ultra-supercritical turbine units. Based on cylinder location, extreme temperature-pressure working conditions, rotor shaft diameter, design radial clearance and installation dimensions, we complete material grade selection, sealing-tooth profile optimization, segment-structure design and high-precision machining. Our solutions cover new-unit supporting, flow-path retrofit performance upgrading, overhaul spare-part replacement and failed sealing-ring renewal.
Key Features
-
High-grade Material Matching for Ultra-supercritical Conditions
Specially selected high-temperature-resistant alloy materials for high-pressure and intermediate-pressure stages to withstand ultra-high temperature and pressure; anti-erosion special alloys are applied for low-pressure wet-steam zones. Outstanding high-temperature strength, oxidation resistance, wear resistance and anti-water-drop-erosion performance. -
Precision-optimized Labyrinth Teeth & Segmented Spring-loaded Structure
Customizable segment quantity, labyrinth tooth geometry, tooth-tip clearance, mounting groove profile and circumferential back-spring structure. Strictly follow original drawings for direct replacement spare parts; we can also redesign tooth patterns for flow-path renovation to further lower steam-leakage rate. -
High-precision Machining & Strict Stress-deformation Control
CNC precision machining for sealing tooth tips and mating mounting surfaces. Professional stress-relieving heat-treatment reduces internal stress, greatly lowering warping and distortion risks caused by frequent temperature cycling. -
Complete Quality Control & Inspection System
Each sealing ring is subject to dimensional inspection, tooth-profile detection, hardness testing and full-range non-destructive testing (NDT), complying with thermal power equipment industry standards. Stable sealing performance, extended service life, reduced unplanned shutdown losses and maintenance costs.
Application Scenarios
Developed for 1000 MW ultra-supercritical steam turbines, applicable to high-pressure, intermediate-pressure and low-pressure shaft gland seals and diaphragm gland seal positions. Widely used for new thermal power plant construction, turbine flow-path efficiency retrofit, unit overhaul spare-part supply and damaged sealing-ring replacement.
