Yuhong Group: Complete Pressure Equipment Solutions – From Components to Fully Insulated Vessels
Yuhong Group Co., Ltd. designs and manufactures a comprehensive range of thermal and pressure equipment for global industries. Our core offerings include shell and tube heat exchangers, pressure vessels, air coolers, and a complete supply of critical components: finned tube bundles, U-tube bundles, heat exchanger tubesheets, and all related parts – ensuring full support for new projects and maintenance.
Shown in the attached photographs is one of our insulated vertical pressure vessels – a custom-engineered unit designed for process storage, separation, or surge control with thermal insulation to maintain process temperature and protect personnel.
Product Focus: Insulated Pressure Vessel – Engineered for Thermal Efficiency & Personnel Safety
A pressure vessel is a closed container designed to hold gases or liquids at pressures substantially different from ambient. This vessel features external insulation with metal cladding – a critical addition for processes requiring temperature maintenance, freeze protection, or personnel burn protection.
Based on the images, this vessel exhibits:
Key Components & Their Functions in an Insulated Pressure Vessel
| Component | Material (Typical) | Role in Equipment Performance |
|---|---|---|
| Shell | Carbon steel (SA516 Gr.70) or stainless steel | Primary pressure-containing boundary; designed for internal/external pressure. |
| Dished Heads (top & bottom) | Carbon steel (formed) or stainless steel | End closures; designed for pressure containment. |
| Insulation Layer | Mineral wool, fiberglass, or foam | Thermal barrier – maintains process temperature; reduces heat loss; protects personnel from burns. |
| Insulation Cladding (Jacket) | Aluminum, stainless steel, or galvanized steel | Protects insulation from weather, mechanical damage, and fire; provides a clean, finished appearance. |
| Manway | Carbon steel or stainless steel | Provides access for internal inspection, cleaning, and maintenance. |
| Nozzles & Flanges | Forged (SA105, SA182) | Process inlet/outlet, instrument connections, drain, vent. |
| Supports (skirt, legs, or saddles) | Structural steel | Support vessel weight; designed for wind, seismic, and operational loads. |
| Lifting Lugs | Carbon steel | Facilitate safe lifting and installation. |
| Internal Coils (optional) | SA179 or stainless steel | Provide heating/cooling surface inside the vessel. |
| Heat Exchanger Tube | Carbon steel or stainless steel | Used in internal coils or external heat exchange circuits. |
Technical Highlights of Our Insulated Pressure Vessel
Knowledge Module: Why Insulate a Pressure Vessel?
| Reason | Benefit |
|---|---|
| Temperature maintenance | Keeps process fluid at required temperature – essential for viscous fluids, chemicals, or exothermic reactions |
| Heat loss reduction | Improves energy efficiency; reduces operating costs |
| Freeze protection | Prevents freezing of water or process fluids in cold climates |
| Personnel protection | Prevents burns from hot surfaces (typically required above 60°C) |
| Condensation prevention | Prevents sweating on cold surfaces – reducing corrosion risk |
| Fire protection | Some insulation materials provide passive fire protection |
| Sound attenuation | Reduces noise from internal flow or pressure relief |
Knowledge Module: Insulation Materials & Cladding Options
| Insulation Material | Temperature Range | Best For |
|---|---|---|
| Mineral Wool (Rockwool) | Up to ~650°C | High-temperature process vessels; fire-resistant |
| Fiberglass | Up to ~250°C | Moderate temperatures; chemical plants |
| Calcium Silicate | Up to ~1000°C | Very high-temperature service |
| Cellular Glass | Cryogenic to ~400°C | Low-temperature service; moisture-resistant |
| Polyurethane Foam | Up to ~120°C | Low-temperature; energy-efficient |
| Cladding Material | Best For | Advantages |
|---|---|---|
| Aluminum | General service; most common | Lightweight; corrosion-resistant; cost-effective |
| Stainless Steel | Corrosive environments; food/pharma | Excellent corrosion resistance; cleanable |
| Galvanized Steel | Outdoor service | Durable; impact-resistant |
