ASME RTP-1 Vessels

ASME RTP-1 is the most comprehensive and active standard in the industry for reinforced thermoset plastic (RTP) equipment.

ASME or American Society of Mechanical Engineers is a high quality design code for many different types of American made products.  RTP-1 was created by ASME for fiberglass reinforced polymer vessels.


Plas-Tank Industries: ASME RTP-1 Certificate of Authorization 

Hamilton, Ohio - Plas-Tanks Industries, Inc., possesses the prestigious “Certificate of Authorization” and corresponding Code Stamp from ASME (American Society of Mechanical Engineers) to produce fiber reinforced plastic vacuum and pressure vessels in accordance with the ASME code procedures.  There are only a few companies, worldwide, who have this honor, which requires certification of laminators and bonders by nationally accredited testing laboratories, plus production and destructive testing of a demonstration vessel.

Fabrication to the RTP-1 standard is widely considered to be the highest level of quality, which provides a level of assurance to the customer that their vessels have been fabricated and inspected under controls surpassing the general industry ASTM standards.  Quality elements in the standard include organizational structure, quality assurance programs, demonstration of capability, material control, inspection, corrective action for nonconforming items, and test control.  All of these elements are controlled in a more comprehensive way at RTP-1 authorized facilities than they are at many typical fabrication companies.  Certificate holders must incorporate all of the elements described above and are subject to audits and reviews of the quality control manual & its implementation.

An ASME certification is essential because it can save the customer in the long term.  The stamping of an ASME tank saves the customer from having to get a tank certified by a 3rd party certification.
