Industrial Dewar Cylinder

Introduction

Our industrial dewar flask is a double-layer container, the inner layer is used to store cryogenic liquids, and the outer layer is used for insulation and protection. The interior is usually filled with a vacuum layer or insulation material to minimize heat transfer, thereby keeping the liquid inside cold. This design enables the industrial dewar flask to keep the liquid cold for a long time without frequent refilling or re-cooling. Our industrial dewar flask has three models to choose from, with a maximum capacity of 189L, and is widely used in chemical, electronic, medical, scientific research and other industries.

 

Advantages

Excellent material

Our industrial dewar flasks are usually made of high-strength stainless steel. Stainless steel has excellent mechanical strength and corrosion resistance, and can withstand the pressure brought by the internal cryogenic liquid and various external shocks and vibrations. Our stainless steel dewar flasks can withstand working pressures up to 2.88MPa.

 

Excellent thermal insulation performance
Our industrial dewar flasks use advanced multi-layer vacuum insulation technology, which greatly reduces heat transfer. Under normal temperature conditions, our industrial dewar flasks can keep the evaporation rate of cryogenic liquids (such as liquid nitrogen) stored inside below 2.0%. This means that even after a long period of storage, the loss of cryogenic liquids can be minimized and the cost of use can be reduced.

 

Applicable to a variety of cryogenic liquids

Industrial dewar flasks can store and transport a variety of cryogenic liquids, such as liquid oxygen, liquid nitrogen, and liquid argon. Different cryogenic liquids have different physical properties and application fields, but our industrial dewar flasks can provide safe and reliable storage and transportation solutions for them.

 

Multiple safety devices

Our industrial dewar flasks are equipped with multiple safety devices such as safety valves, bursting discs, and pressure sensors. When the pressure inside the bottle exceeds the set value, the safety valve will automatically open to release the pressure and prevent the bottle from exploding.

 

Application

Chemical Industry
In the chemical industry, industrial dewar flasks can be used to store and transport various cryogenic liquids, such as liquid oxygen, liquid nitrogen, liquid argon, etc. These cryogenic liquids can be used as chemical raw materials or reaction media in various chemical production processes. Liquid oxygen can be used for oxidation reactions, liquid nitrogen can be used for freeze drying and cryogenic crushing, and liquid argon can be used for protective gas and welding, etc.

 

Medical Equipment Cooling
In the medical field, industrial dewar flasks are mainly used to store and supply liquid helium and liquid nitrogen. Liquid helium and liquid nitrogen can be used to cool medical equipment, such as magnetic resonance imaging (MRI) equipment, linear accelerators, etc. In MRI equipment, liquid helium is used to cool superconducting magnets, enabling them to generate strong magnetic fields for imaging of human tissues. In linear accelerators, liquid nitrogen can be used to cool accelerating tubes to improve the performance and stability of accelerating tubes.

 

Electronic Manufacturing
In the electronics manufacturing industry, industrial dewar flasks are mainly used to store and supply liquid helium. Liquid helium is an ultra-low temperature liquid with a boiling point of -268.9℃. Liquid helium can be used to cool superconducting materials and electronic devices, allowing them to operate at extremely low temperatures, thereby improving their performance and stability.

 

Metalworking
In the metalworking industry, industrial dewar flasks are mainly used to store and supply liquid nitrogen. Liquid nitrogen can be used to cool and quench metals, which can significantly increase the hardness and strength of metals. In steel production, liquid nitrogen quenching can increase the hardness of steel several times, while also improving the toughness and wear resistance of steel.

 

 

 

Frequently Asked Questions

 

1. What is the main purpose of industrial dewar cylinder?
Industrial dewar cylinder is mainly used to store and transport cryogenic liquids, such as liquid nitrogen, liquid oxygen, liquid argon, etc. These cryogenic liquids are widely used in scientific research, medical treatment, industrial manufacturing, food processing, and other fields. Dewar flask can keep the liquid in a low-temperature state for a long time through its efficient insulation performance, ensuring the stability and use effect of the liquid.

 

2. What is the insulation principle of an industrial dewar cylinder?
The insulation principle of industrial dewar cylinders is mainly based on multi-layer vacuum insulation technology. The inside of the bottle body consists of an inner liner and an outer shell, and the space between the two is evacuated into a vacuum state to reduce heat conduction and heat convection. At the same time, the space between the inner liner and the outer shell may also be filled with insulating materials, such as glass fiber, vacuum powder, etc., to further improve the insulation effect. This design enables the Dewar flask to effectively isolate external heat and maintain internal low temperature.

 

3. What is the material of industrial dewar cylinder usually?
The material selection of industrial dewar cylinder is crucial to its performance and service life. The inner tank is usually made of corrosion-resistant and low-temperature resistant materials such as stainless steel to ensure that cryogenic liquids can be stored for a long time without leakage or corrosion. The outer shell may be made of stainless steel, aluminum alloy, or other lightweight and high-strength metal materials to improve the overall strength and durability of the Dewar flask.

 

4. How to ensure the sealing performance of the industrial dewar cylinder?

The sealing performance of the industrial dewar cylinder is the key to ensuring its safe use and effective insulation. The Dewar flask usually adopts multiple sealing structures, including the seal between the inner tank and the neck tube, and the seal between the neck tube and the valve.
