For Project Engineers

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

1

Atmospheric Storage Tanks

 

2

Low Pressure Tanks

 

3

Process Vessels

4

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.
