Products :: ASME RTP-1 Code Stamped Vessels

ASME RTP-1 Official Stamp is placed on the vessel's nameplate and registered with the National Board.
The official symbol for ASME RTP-1 stamped vessels.

ASME RTP-1 Overview
The American Society of Mechanical Engineers (ASME) is a design code and standards setting body for many different products. ASME established the RTP-1 standard for fiberglass reinforced polymer vessels in 1989. The standard is widely held to be the most stringent and complete tool for producing high quality FRP vessels. The standard establishes rules for:

  • End user and fabricator responsibilities
  • Materials of contruction
  • Design of vessels by rules and analysis
  • Fabrication details
  • Quality assurance
  • Fabricator qualification, accreditation and third party audit
The goals of the RTP-1 standard are to:
  • Provide for protection of life and property
  • Provide a margin of deterioration that allows for a reasonably long period of usefulness

Benfits of Using the RTP-1 Standard
When you use an ASME RTP-1 certified fabricator with the RTP-1 standard, you benefit through:

  • 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 - Accredited fabricators subject themselves to self audits and third party audits to ensure compliance with the requirements of the standard.

    Accredited fabricators have qualified laminators and secondary bonders that have fabricated and tested demonstration laminates to meet RTP-1 requirements.

  • Fabricator Compliance - Requiring the RTP-1 stamp on a vessel signifys the fabricators full compliance to the standard.

ASME RTP-1 Stamping
When a vessel complies fully with the RTP-1 standard, it is eligible for stamping. Stamping the vessel signifies the vessel has passed the customer's and fabricator's quality assurance requirements. The vessel is uniquely numbered and the above symbol is affixed to the vessel. Further, the tank is registered with the National Board of Boiler's and Pressure Vessels.
