Notes
Custom Sizing: The length, outer diameter, inner diameter, and wall thickness in the table can be adjusted within a reasonable range according to customer requirements (e.g., the minimum outer diameter can be customized to 3mm, the maximum to 100mm, and the maximum length to 15000mm).
Performance Optimization: If customers have higher requirements for specific properties (such as corrosion resistance, high-temperature resistance), the resin type can be replaced (e.g., polyimide resin can be used to improve high-temperature resistance) or the carbon fiber lay-up method can be adjusted.
Testing Standards: All products undergo performance testing in accordance with GB/T 35465-2017 Carbon Fiber Reinforced Composite Pipes before leaving the factory to ensure that parameters meet the standards.
Appearance Options: A matte surface is provided by default; glossy surfaces, colored coatings, or surface texture treatments can be customized according to requirements.
