In modern power generation systems—whether coal, gas, nuclear, hydro, or renewables—fluid handling, sealing, and expansion control are mission-critical. Failures or leaks in hoses, gaskets, or bellows not only risk downtime but also safety and regulatory non‑compliance. At National Hose, we deliver engineered solutions tailored for power‑generation environments to ensure uptime, integrity, and performance under extreme conditions.
Challenges in Power Generation Fluid & Sealing Systems
Power plants operate under high pressure, high temperature, vibration, thermal cycling, and harsh chemical environments. Typical challenges include:
- Thermal expansion and movement causing stress on piping
- Corrosive fluids, steam, and contaminants degrading seals
- Vibration and pulsation inducing fatigue
- High-pressure leaks in flanges or joints
- Need for custom configurations to fit tight plant layouts
Such challenges demand components that are precisely engineered—not generic “off‑the-shelf” parts.
Hoses, Gaskets & Bellows as the Core Solution Components
Hoses & Hose Assemblies
- Flexible metal hose assemblies that absorb vibration, support thermal expansion, and isolate sensitive equipment
- PTFE or elastomer hoses for liquids, chemicals, or auxiliary systems
- Custom hose assemblies rated for steam, oil, or gas service
Gaskets & Sealing Solutions
- Metallic, composite, and elastomeric gaskets suitable for high-temp, high-pressure flanges
- Spiral-wound and jacketed gaskets for steam service
- Custom-fabricated gaskets to fit unusual geometries or retrofit jobs (National Hose maintains a broad gasket inventory and custom fabrication capability)
Bellows & Expansion Joints
- Metal bellows (expansion joints) that accommodate axial, lateral, and angular motion
- Combining bellows with flexible connectors or hoses to reduce stress on piping
- Designed to endure high-cycle fatigue in steam or thermal loops
Key Benefits & Applications
Here are the principal benefits and application use cases:
| Benefit | Application or Impact |
| Leak-Free Integrity | Reduces costly downtime and environmental or safety risk |
| Vibration & Thermal Compensation | Extends life of piping, equipment, and joints |
| Custom Engineering | Fits unique plant layouts or retrofit constraints |
| Material Compatibility | Withstands corrosive fluids, steam, and elevated temperature |
| Single-Source Integration | Hoses, gaskets, and bellows from a coordinated partner (National Hose) |
Use cases include steam loops, feedwater systems, auxiliary cooling lines, gas injection lines, turbine exhaust interfaces, and smaller utility connections.

FAQs
Q1: How do I choose between a metal hose and a rubber/elastomer Hose?
A: Use metal hoses or bellows when temperature, pressure, or motion levels exceed what elastomeric hoses can reliably handle. For lower-temperature liquids or where cost is a concern, elastomeric or PTFE hoses may suffice. Always match the hose material, reinforcement, and end fittings to the specific fluid, pressure, and environment.
Q2: What kind of gaskets are ideal for high‑temperature steam service?
A: Spiral-wound, metal-jacketed, or corrugated-metal gaskets are common choices for steam applications. These constructions accommodate differential expansion and maintain sealing under fluctuating temperature and pressure.
Q3: Can you retrofit bellows or expansion joints into existing piping systems?
A: Yes. We often engineer expansion joints to adapt to existing flanges or piping geometry. Our custom fabrication ensures compatibility, minimal downtime, and correct movement compensation.
Q4: What lead times can National Hose provide for custom assemblies?
A: We maintain significant in-stock capacity for many hose, gasket, and expansion joint components, enabling faster turnaround. For custom work, lead times depend on complexity, but our fabrication capabilities aim to minimize delays.
