PIP VESFG001

This Practice describes the general materials selection, design, fabrication, testing, inspection, and documentation requirements for fiberglass vessels and tanks to be constructed in accordance with ASME Boiler and Pressure Vessel Code Section or ASME/ANSI RTP-1. Fabrication shall be by ASME-accredited manufacturers. When the type of fiberglass fabrication is not covered by Section X or RTP-1, the Purchaser should use this Practice for guidance. In addition, Sections 5 and 11 provide guidance for the User or Designer in developing procurement specifications and installation practices for this equipment. Sections 5 and 11 are not the responsibility of the Fabricator.

This Practice designates general requirements for the design and construction of aboveground fiberglass reinforced polyester, vinyl ester, and epoxy tanks and vessels having internal or external pressure from full vacuum up to the limits of Section X. Shop- and field-fabricated equipment, thermoplastic-lined equipment, and dual laminate equipment are covered in the scope of this Practice. Not covered are fiberglass hoods, ducts, stacks, pumps, fans, blowers, piping, and fully buried tanks that are beyond the scope of the referenced standards. Furan and phenolic resins, non-glass structural reinforcement, and metallic-lined fiberglass vessels are also outside the scope of this Practice.
