The operating temperature range of cryogenic pipes can be defined differently, depending on different standards and application areas.
Generally speaking, cryogenic pipes refer to pipes with a working temperature below **-40°C. However, in some cases, cryogenic pipes may have a wider operating temperature range, such as -45°C~-195°C**. Such pipes are often used in specific low-temperature environments, such as cryogenic pressure vessel pipes and cryogenic heat exchanger pipes.
It should be noted that the definition of cryogenic pipes may be different for different industries and different application scenarios. Therefore, in practical applications, the operating temperature range of cryogenic pipes should be determined according to the specific requirements and relevant standards.
At the same time, in order to ensure the safe operation of low-temperature pipelines, materials with excellent low-temperature properties should be selected, and necessary insulation measures should be taken to prevent brittle fractures and other problems in pipelines due to low temperatures. In addition, the design, manufacture, installation and operation of cryogenic pipes should also be strictly adhered to relevant standards and specifications to ensure that they are safe, reliable and efficient.
What is the difference between cryogenic pipes and ultra-low temperature pipes
There are significant differences between cryogenic and ultra-low temperature pipelines in several ways.
First of all, their main difference is the range of operating temperatures. Cryogenic pipes typically operate at temperatures below -45°C, while ultra-low temperatures can be even lower, involving more extreme cryogenic environments. This difference in temperature range makes the two different in terms of material selection, manufacturing process, and field of application.
Secondly, from the material point of view, ultra-low temperature pipes have more stringent requirements for materials. In ultra-low temperature environments, materials need to have better low temperature toughness, crack resistance, and fatigue resistance to ensure that pipelines do not break or leak under extremely low temperature conditions. As a result, ultra-low temperature pipes are often made of more specific materials to meet the unique needs of their working environment.
In addition, the two are also different in structural design and installation process. Cryogenic pipes are usually installed in special ways such as welding to ensure their good sealing and stability. However, due to the more extreme working environment, ultra-low temperature pipelines may require more complex bracket forms, such as a combination of reinforced and semi-reinforced brackets, to alleviate the pipeline deformation caused by low temperatures.
Finally, in terms of application fields, cryogenic pipelines are widely used in industrial fields such as liquefied natural gas, refrigerants, liquid oxygen, and liquid nitrogen. Ultra-low temperature pipelines may involve more special fields, such as superconducting technology, cryogenic treatment, etc., which have more stringent requirements for the performance of pipelines.
To sum up, there are obvious differences between cryogenic pipes and ultra-low temperature pipelines in terms of operating temperature, material selection, structural design and application fields. These differences allow them to adapt to different working environments and needs for efficient and safe media transfer.
