When selecting cryogenic tubing, there are several factors that need to be considered to ensure that the tubing meets the specific application needs, including but not limited to the following:
Material Selection:
Stainless steel pipes
It has good low-temperature performance and high strength, and also has excellent corrosion resistance.
Aluminum alloy pipe
It has excellent low-temperature performance and good mechanical properties, high tensile strength, and good corrosion resistance.
Alloy steel
Combines the advantages of carbon steel and stainless steel to provide higher strength and corrosion resistance, making it suitable for harsher low-temperature environments.
Nickel-based low-temperature steel: With nickel as the main element, it can improve the low-temperature toughness of the steel, and is suitable for equipment in a specific low temperature range.
Low-carbon aluminum sedative steel
With silicon-manganese as the main component, adding an appropriate amount of aluminum and fine grains can improve the toughness of steel and improve aging performance.
Polyurethane pipe
when used under low temperature conditions, it has good impact resistance, corrosion resistance, and good thermal insulation performance.
FRP pipe
When used under low temperature conditions, it has excellent corrosion resistance and strength, is an insulating material, and will not conduct electricity.
Temperature range
Determine the minimum temperature that the pipe needs to withstand, and select a pipe material that has sufficient performance within that temperature range.
Pressure requirements
Select the pipe according to the working pressure of the system to ensure that it has sufficient pressure capacity.
Corrosiveness
Considering the corrosive characteristics of the environment in which the pipeline is located, select materials with corresponding corrosion resistance.
Processing & Installation: Consider the processing and welding properties of the material, as well as the ease of installation and maintenance.
Economy
On the premise of meeting the technical requirements, consider the price of materials and procurement costs.
Brand and quality
Choose well-known brand pipeline products, such as Rifeng, Weixing, etc., to ensure the quality and reliability of the products.
Standards and Specifications
Ensure that the selected pipes meet the requirements of relevant standards and specifications, such as national standards, industry standards, etc.
In short, when choosing a cryogenic pipeline, it is necessary to comprehensively consider multiple factors such as material, temperature range, pressure requirements, corrosivity, processing and installation, economy, brand and quality, and standards and specifications. It is advisable to communicate with a professional engineer or supplier to ensure that the selected pipe will meet the specific application needs.
