What is BS EN 13923 – Filament wound FRP pressure vessels about?
BS EN 13923 is a European standard that specifies the requirements for the design including raw materials, calculation, manufacturing including composite materials, and testing of seamless Glass Reinforced Plastic (GRP) pressure vessels with a protective layer, using only multi-directional filament winding, made in a factory and for use above ground and for storage and processing of fluids.
BS EN 13923 covers vessels subject to pressures below 20 MPa and temperatures between – 30 °C and 120 °C. BS EN 13923 specifies two design methods for filament wound GRP pressure vessels. In BS EN 13923 only the winding is considered in the calculation of the strength and the stiffness of the shell. Method A describes the calculation of the reinforcement of the cylindrical shell and the end domes based on netting theory. Method B describes the calculation of the reinforcement of the cylindrical shell and the end domes based on laminate theory.
Note: Excluded from BS EN 13923 are transportation vessels, double-wall vessels, vessels under negative pressure, and vessels that are subjected to the risk of explosion or failure which may cause an emission of radioactivity.
Who is BS EN 13923 – Filament wound FRP pressure vessels for?
BS EN 13923 on filament wound FRP pressure vessels is useful for:
- The chemical industry
- The metal industry
- The food processing industry
- The petrochemical industry
- Testing and inspection officers
- Pressure vessels manufacturers
Why should you use BS EN 13923 – Filament wound FRP pressure vessels?
The design and manufacture of filament wound GRP pressure vessels involve a number of different materials, such as resins, thermoplastics, and reinforcement fibres. FRP Pressure Vessels are simple to handle and install and come in either a regular polyester or a chemical-resistant vinyl ester structure, depending on your requirements. BS EN 13923 specifies stress and strain limits and the requirements for the acceptance testing. FRP vessels are long-lasting, lightweight, flexible, strong, corrosion-resistant, and less expensive than steel tanks or vessels.
BS EN 13923 provides its users with guidelines for the design documentation, manufacturing specifications, and instructions for test methods for performance, pressure, and acceptance testing. Using BS EN 13923 guidelines ensures high quality, performance, safety, and cost-effectiveness.
