Specification selection guide
When selecting the appropriate stainless steel precision tube specification, you need to consider multiple factors to ensure that the selected specification can meet the needs of the actual application. Here are some key selection points:
1. Clarify the application requirements
Working pressure: Determine the required pipe wall thickness and strength based on the working pressure of the pipeline system. High-pressure environments require thicker pipe walls and higher strength.
Working temperature: Stainless steel precision tubes are suitable for high-temperature environments, but the appropriate specifications must be selected according to the specific working temperature to ensure the mechanical properties and corrosion resistance of the material at high temperatures.
Medium characteristics: Understand the properties of the fluid in the pipeline, such as corrosiveness, viscosity, temperature, etc., and select pipe specifications that can resist medium erosion.
2. Consider the pipe size
Outer diameter: Select the appropriate outer diameter based on flow requirements and pipeline layout. The larger the outer diameter, the greater the flow, but the higher the cost.
Wall thickness: Wall thickness directly affects the pressure bearing capacity and service life of the pipeline. The wall thickness needs to be determined based on the working pressure, temperature and medium characteristics.
Length: Develop the pipeline length according to actual needs, reduce the number of joints, and improve system reliability.
3. Reference standards and specifications
National standards: Refer to relevant national standards, such as GB/T, to ensure that the selected specifications meet industry requirements.
Industry standards: Some specific industries may have more stringent standards, which need to be selected according to specific industry specifications.
Manufacturer recommendations: Consult manufacturers or suppliers to obtain specification recommendations and technical support for specific applications.
4. Comprehensive evaluation and selection
Cost-effectiveness: Consider cost factors and select cost-effective specifications while meeting performance requirements.
Processability: Select pipe specifications that are easy to cut, bend and weld according to processing requirements.
Corrosion resistance: Stainless steel itself has good corrosion resistance, but the corrosion resistance of different specifications in specific media may vary, and needs to be selected according to the characteristics of the media.
Summary
The specifications of stainless steel precision tubes of different materials may vary, and the specific selection should be based on actual needs. The above table is for reference only, and the specific selection should be based on the product catalog or technical parameters provided by the manufacturer.
