ASME BPVC Section X: Fiber-Reinforced Plastic Pressure Vessels, 2023

ASME BPVC Section X – 2023 provides the design, fabrication, inspection, and testing rules for pressure vessels made primarily from fiber-reinforced plastic (FRP) materials. It applies to vessels built using bag-molding, centrifugal-casting, filament-winding, and contact-molding techniques, and includes Class I, II, and III pressure vessels. This section supports the integration of composite materials in high-performance applications where weight, corrosion resistance, and strength are key considerations.

Highlights:

• Rules for laminate material selection, qualification, and degradation allowances
• Design methodology for internal and external pressure, loadings, and structural reinforcements
• Fabrication specifications for five primary FRP processes including molds, liners, and bonded joints
• Inspection procedures and test protocols for Class I and II vessels
• Requirements for inspectors, data reports, and certification marking
• Appendices for laminate theory, stiffness coefficients, and NASA-based stress solutions
• Special provisions for vessels with metallic liners and hybrid laminate structures
• Guidance for fire exposure mitigation and pressure relief strategies

Who It’s For:
Engineers, fabricators, and quality assurance professionals working with composite pressure vessels in chemical processing, aerospace, water treatment, and industrial applications requiring ASME code compliance.
