Large External Coil Tube Heating and Insulation Pressure Storage Tank

Product Attributes

Our Large External Coil Tube Heating And Insulation Pressure Storage Tank is a high-performance, custom-engineered pressure vessel designed for the most demanding industrial applications in chemical processing, petrochemical, pharmaceutical, food & beverage, and energy sectors. Engineered to meet international standards including ASME, GB150, and PED, this storage tank combines robust structural integrity, precise temperature control, and long-term corrosion resistance, making it the ideal solution for storing, heating, and maintaining temperature-sensitive liquid media under controlled pressure conditions. Unlike conventional jacketed tanks, the external coil tube design delivers superior heat transfer efficiency, uniform temperature distribution, and easy maintenance, while the integrated insulation system minimizes energy loss and ensures stable process conditions even in extreme ambient environments.

Key Design & Structural Features

1. Advanced External Coil Tube Heating System

The core of this storage tank is its high-efficiency external coil tube heating structure, engineered to optimize thermal performance and operational reliability:

Superior Heat Transfer: The helically wound external coil tubes are precision-welded to the tank shell, creating a large heat exchange surface area that delivers 20-30% higher heat transfer efficiency compared to traditional full jackets. This enables rapid, uniform heating of stored media (e.g., viscous chemicals, molten wax, edible oils, or process fluids) without hotspots, ensuring consistent product quality and process stability.
Flexible Heating Medium Compatibility: The coil system is compatible with a wide range of heating media, including high-temperature steam, thermal oil, hot water, and even heat transfer fluids for low-temperature applications. This versatility allows seamless integration into existing process lines, whether for continuous heating, batch temperature maintenance, or freeze protection.
Modular & Maintainable Design: The external coil configuration eliminates the need for internal heating elements, reducing the risk of media contamination and simplifying inspection, cleaning, and maintenance. Coil tubes can be individually repaired or replaced without draining the entire tank, minimizing downtime and operational costs.
Pressure-Resistant Coil Construction: Each coil tube is manufactured from high-grade stainless steel (304/316L/321/2205 duplex) and pressure-tested to 1.5 times the design pressure, ensuring leak-free operation even under high-temperature, high-pressure process conditions.

2. Robust Pressure Vessel Construction

Built to the strictest global pressure vessel standards, the tank shell and structure are engineered for long-term safety and durability:

Premium Material Selection: The tank body is constructed from high-quality stainless steel (ASME SA240 304/316L/321/2205 duplex) or carbon steel with corrosion-resistant lining, selected based on the specific chemical properties of the stored media, operating pressure, and temperature. All materials are fully traceable with mill test certificates (MTC) and comply with international material standards.
Precision Welding & Fabrication: All welds are performed by certified ASME IX welders using advanced TIG/MIG welding processes, with 100% radiographic (RT) or ultrasonic (UT) inspection to ensure weld integrity. The tank shell is hydrostatically tested to 1.3 times the design pressure, and pneumatic testing is available for special applications, guaranteeing zero leakage and compliance with pressure vessel safety regulations.
Customizable Design Pressure & Temperature: The tank is engineered to meet custom design requirements, with operating pressures ranging from full vacuum (-0.1MPa) to 16MPa, and operating temperatures from -196°C (cryogenic) to 600°C (high-temperature process), making it suitable for a diverse range of industrial storage and process needs.
Reinforced Structural Support: The tank is equipped with heavy-duty carbon steel support skirts or saddles, designed to withstand the full weight of the tank, media, and external loads (e.g., wind, seismic activity), ensuring stable installation and long-term structural safety.

3. High-Performance Insulation System

To minimize energy consumption and maintain precise temperature control, the tank is integrated with a premium thermal insulation system:

Multi-Layer Insulation Structure: The system typically consists of a high-density rock wool, polyurethane (PU), or polyisocyanurate (PIR) insulation layer, covered with a stainless steel or aluminum cladding. This structure provides exceptional thermal resistance, reducing heat loss by up to 90% compared to uninsulated tanks, significantly lowering energy costs for heating and temperature maintenance.
Custom Insulation Solutions: For extreme temperature applications (e.g., cryogenic storage or high-temperature process fluids), we offer specialized insulation solutions such as vacuum insulation panels (VIP) or high-temperature ceramic fiber insulation, tailored to the specific operating conditions.
Weather-Resistant Cladding: The outer cladding is designed to protect the insulation from moisture, UV radiation, and mechanical damage, ensuring long-term insulation performance and extending the tank's service life. The cladding can be customized with color, finish, and branding options to meet aesthetic and operational requirements.

4. Comprehensive Process Accessories

Each storage tank is fully customizable with a complete range of process accessories to meet specific operational needs:

Manways & Inspection Ports: Large-diameter quick-opening or bolted manways for easy access, cleaning, and maintenance, with optional sight glasses for visual inspection of stored media.
Nozzles & Connections: Custom-sized inlet/outlet nozzles, sampling ports, level gauge connections, pressure relief valves, safety valves, and rupture discs, engineered to meet ASME B16.5/ B16.47 flange standards for seamless integration with process piping.
Level & Temperature Monitoring: High-precision level transmitters (magnetostrictive, radar, or float type), temperature sensors (PT100, thermocouples), and pressure transmitters for real-time monitoring of tank conditions, with compatibility for SCADA and DCS process control systems.
Mixing & Agitation Systems: Optional top-entry, side-entry, or bottom-entry agitators for mixing stored media, preventing sedimentation, and ensuring uniform temperature distribution, ideal for viscous fluids or multi-component chemical storage.
Safety & Control Systems: Pressure safety valves, emergency relief systems, flame arrestors, and overfill protection systems to ensure compliance with industrial safety standards and prevent operational hazards.
