Technical Specifications
We help engineers move FRP projects from design requirements to manufacturing and installation.
Pressure Rating
- Hebei jiarui designs and manufactures FRP equipment according to project operating conditions.
- Available pressure ratings can be customized based on customer requirements, operating medium, temperature, and design standards.
- Pressure calculations are performed during the engineering design stage to ensure long-term structural safety.
Typical applications include
Atmospheric Storage Tanks
Low Pressure Tanks
Process Vessels
FRP Piping Systems
Operating Temperature
- The operating temperature depends on the selected resin system and chemical environment.
- Typical operating temperatures range from ambient conditions to high-temperature industrial applications.
- Different resin systems are recommended according to service conditions.
