What is RTP-1?

The American Society of Mechanical Engineers (ASME) is a design code and standards setting body. ASME established the RTP-1 standard for fiberglass reinforced plastic vessels in 1989. The standard is widely held to be the most stringent and complete tool for qualifying fabricators specifying high quality FRP and dual laminate vessels. The standard establishes rules for:

  • End-user and fabricator responsibilities
  • Materials of construction
  • Design of vessels by rules and analysis
  • Fabrication
  • Quality assurance
  • Fabricator qualification, accreditation and audited by ASME

RTP-1 Accreditation Process

The Design and Fabrication of the Demonstration Vessels required a comprehensive understanding of the ASME RTP-1 Standard. The authorization process involved B&D Plastics building Demonstration Vessels. B&D plastics:

  • Designed the Vessel
  • Executed Fabrication Drawings
  • Fabricated and Tested shop demonstration laminates
  • Established design values from design basis laminates
  • Qualified Laminators, Secondary Bonders and Thermoplastic Welders
  • Fabricated, Inspected, Tested, Documented and Sectioned the demonstration vessels, M-6 and M-12, per mandatory appendices.

The RTP-1 Certificate of Authorization was approved by ASME and Certificate Number RTP-022 was assigned to B&D Plastics, LLC.

FRP and Dual Laminates

The benefits of using an ASME RTP-1 Authorized Fabricator include (but are not limited to)

  • Risk Management: The standard is developed with input from expert stakeholders in the FRP industry and is overseen by a highly respected engineering organization, the ASME.
  • Fabricator Vetting: Authorized fabricators subject themselves to self audits and audits by ASME to ensure compliance with the requirements of the standard. Authorized Fabricators have Laminators, Secondary Bonders and Thermoplastic Welders that are qualified per the requirements of ASME RTP-1.
  • Fabricator Compliance: Requiring the RTP-1 stamp on a vessel signifies the fabricators full compliance to the standard.
