Cryogenic Liquid Nitrogen (LN2) Storage Tanks: Specifications & Features

Cryogenic Liquid Nitrogen (LN2) Storage Tanks: Specifications & Features

Introduction:

Cryogenic liquid nitrogen (LN2) Storage tanks are specialized vessels designed for the safe and efficient storage of liquid nitrogen and other cryogenic fluids like liquid oxygen (LOX), liquid argon (LAr), and liquid carbon dioxide (LCO2). These tanks are crucial in various industries, including healthcare, manufacturing, research, and food processing, where maintaining the extremely low temperatures of these liquids is essential. This document details the specifications and features of our high-quality LN2 storage tanks, highlighting their robust construction, superior insulation, and adherence to stringent safety standards.

LN2 Tank Parameter Specifications:

Our range of cryogenic liquid storage tanks are available in various sizes and pressure ratings to meet diverse application requirements.  The following table outlines the key parameters for our standard models:

Key Features & Benefits:

• Versatile Working Medium: Designed for storing liquid nitrogen (LN2), liquid oxygen (LOX), liquid argon (LAr), and liquid carbon dioxide (LCO2), providing flexibility for various industrial applications.

• Durable Construction: Manufactured using high-quality materials and advanced welding techniques to ensure long-term reliability and structural integrity.

• Efficient Insulation: Utilizing a high-vacuum, multi-layer insulation system to minimize heat leak and reduce boil-off rates, resulting in lower operating costs.  This superior insulation is crucial for maintaining the cryogenic temperatures required for LN2 storage.

• Safety Features: Equipped with multiple safety features, including pressure relief valves, rupture disks, and level indicators, to ensure safe operation and prevent accidents.

• Customizable Options: Available in various sizes and pressure ratings, with options for customized connections, instrumentation, and control systems to meet specific customer requirements.

Paint Specifications:

The exterior of our LN2 tanks is coated with a durable paint system to protect against corrosion and environmental factors.

• Coating System: We use a high-performance paint system consisting of a primer and a topcoat.  The topcoat is typically an Acrylic Polyurethane or an imported equivalent with enhanced UV resistance.

• Application: The primer is applied in two coats, followed by one coat of the topcoat, resulting in a total of three coats.

• Total Thickness:  The total paint thickness exceeds 250 microns, providing excellent protection against corrosion and abrasion.

Vacuum Performance:

Maintaining a high vacuum level within the insulation space is critical for minimizing heat transfer and ensuring efficient cryogenic storage.

• Inner Cylinder Treatment: The inner cylinder undergoes a circulation heating process to remove any residual moisture, ensuring a clean and dry environment for optimal vacuum performance.

• Vacuum Stability: We conduct static observation tests to verify that the vacuum level remains stable over a period of one month, ensuring long-term insulation performance.

• Nitrogen Pressure Testing:  All tanks are pressure tested using gas nitrogen, which is free of water and oil, preventing any contamination during the testing process.  This ensures the integrity and cleanliness of the system.

Valve Specifications:

The valves used in our LN2 tanks are selected for their reliability and performance in cryogenic applications.

• Standard Valves: We typically use high-quality Chinese valves that meet international standards.

• Optional Valves:  We can also provide imported valves from reputable manufacturers based on specific customer requirements.
