Steam Turbine Vapor Seal Rings: High-Performance Sealing Solutions
Product Overview
The steam turbine steam seal ring is the core sealing component of the steam turbine, which is designed for high-temperature and high-pressure steam environments and is widely used in steam power systems in power plants, petrochemicals, ships, and other fields. Its core function is to prevent high-temperature steam leakage while blocking the ingress of external impurities, ensuring the efficiency and safety of steam turbine operation. As a key part of sealing technology, our vapor sealing rings are made of advanced alloy materials and precision forging technology, which can withstand high temperatures above 600°C and pressures above 2.4MPa, meeting the needs of harsh working conditions around the world.
| Operating temperature | -60°C to 600°C (customized according to material) |
| Compressive strength | ≤16MPa (static seal) |
| Material Options | R-26 alloy, 0Cr18Ni9, fluoroelastomer, silicone, etc |
| Adaptation criteria | GB/T, ASME, DIN, JIS, and other international standards |
Core Advantages and Technological Innovation
Excellent material properties
High-temperature alloy material: R-26 superalloy, 0Cr18Ni9 stainless steel, and other special materials, both high temperature oxidation resistance and chemical corrosion resistance, suitable for 300 °C ~ 600 °C extreme environment, long-term structural stability.
Composite seal design: combining metal sealing rings and auxiliary rubber seals (such as fluoroelastomer O-rings), the elasticity of rubber is used to compensate for the thermal expansion and contraction of metal parts to achieve double sealing guarantee. Fluoroelastomer has a temperature resistance of up to 250°C, and nitrile rubber has strong oil resistance, which is suitable for different media needs.
Precision manufacturing process
Forging process optimization: multi-stage heating and precise temperature control technology are adopted to avoid grain roughening and cracking, ensure that the grain size of forgings reaches more than 3, and increase the material utilization rate by 15%.
Tooling finishing technology: By correcting the punch and horse bar reaming process, the inner and outer circle accuracy is controlled to ±0.05mm, reducing the machining allowance and reducing the cost.
Strict quality inspection
Implement the GB/T14999.5 standard to conduct a comprehensive test on the micro-grain size, tensile strength, and corrosion resistance to ensure that each product meets the requirements of long-term operation of the power plant.
Application scenarios and compatible models
Applicable units: covering a full range of steam turbines from 1.5MW to 1000MW, including key parts such as the main steam intake system, high-pressure steam guide pipeline, and valve seal.
Industries: High-temperature and high-pressure sealing scenarios such as thermal power generation, nuclear power, chemical industry, and ship power systems.
