RTP-1 Tanks

RTP-1 Tanks


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-Tanks 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 ten 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 (shown here).


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.

Plas-Tanks was established in 1976 producing chemically resistant equipment of non-corroding non-metallic materials for food, drug, chemical, power, air, water and waste treatment projects.

The Plas-Tanks Industries' Bryneer

The Bryneer bulk salt storage and brine maker was the first brining system that is completely designed and manufactured by a fiberglass reinforced plastic (FRP) fabricator.

Offering single source brining components for economical solutions and dependability, Bryneers are manufactured to current industry standards. USDA-approved resins are conditioned to meet food grade sanitary guidelines.

Plas-Tanks provides an exclusive two-year warranty backing for manufactured vessels.

A plenum on the bottom of the vessel collects brine evenly over the entire surface area of the vessel. It filters undissolved salt crystals and insolubles from effluent saturated brine. An outlet pipe draws brine through a nozzle in the vessel wall.

All Plas-Tanks’ Bryneers are fitted with a side-mounted, leak proof man way near the base for convenient clean-out access. If required, all collection and outlet internal piping is removable through the man way for cleaning or repair.

Downflow Brine Making
The downflow brining principle ensures consistent brine saturation. As influent water rises, higher density brine sinks. Sludge from rock and solar salt is concentrated at the bottom of the Bryneer where it can be periodically removed.

Uniform Distribution
In many commercial brine makers, inlet water is not distributed evenly. Eventually, this results in the formation of salt pillars in the vessels, which may collapse and damage the vessel. The Bryneer eliminates this problem by use of an induction header around the inside circumference of the vessel.

Rapid Loading without the Dust
A pneumatic loading and air venting system is designed for rapid loading, easy maintenance and minimum dust emissions. The fill pipe is mounted for center fill using a long radius turn to minimize particle attrition while water is introduced to minimize dust.

Effective Liquid Level Control System
The Bryneer incorporates a unique brine level control system to open and close a valve in the water inlet line. The level control can be set for any desired liquid level. The digital level control is contained in a corrosion resistant waterproof box. The unit comes complete with a digital display indicative of the brine solution level.

Maintenance Free
Plas-Tanks Industries’ tough, damage resistant fiberglass reinforced plastic shell is constructed to withstand many years of brine making with little to no maintenance required.

National Sanitation Foundation (NSF) Approved
Plas-Tanks’ Bryneer is NSF-61 certified to control the potentially adverse health effects of products added directly to water for its treatment, storage and transmission.
