About the ASME Reinforced Thermoset Plastic Corrosion-Resistant Equipment Certification Program

The Reinforced Thermoset Plastic (RTP) Corrosion-Resistant Equipment Certification Program applies to stationary vessels used for the storage, accumulation, or processing of corrosive or other substances at pressures not exceeding 15 psig external and/or 15 psig internal above any hydrostatic head. The RTP Certification Program requires fabrication done by hand lay-up but also allows for spray-up and filament wound methods of fabrication. ASME RTP certificates can also be extended to include field assembly and repair and field fabrication. The Certification Mark with an RTP Designator indicates that vessels bearing the Mark have been manufactured by a fabricator that has been certified by ASME and possesses a valid ASME RTP Certificate of Authorization.

Like the ASME Boiler and Pressure Vessel Code (BPVC) and nuclear programs, RTP vessels can also be registered by filing the fabricator's data report with The National Board of Boiler and Pressure Vessel Inspectors, 1055 Crupper Avenue, Columbus, OH 43229.
