The Design Tanks Difference: Exceeding The Standards

Categories:

What are Design Tanks manufacturing standards?

The three predominant standards today that relate to fiberglass tanks and vessels are:

1. ASTM D3299

2. ASTM D4097

3. ASME RTP-1

As a custom manufacturer specializing in meeting the unique needs of our customers, our exposure to these different standards is much higher than for the manufacturer that produces a cookie cutter tank. To add some clarity to the conversation, we’re focusing on where Design Tanks is positioned when it comes to standards and what that means in terms of the tank you order.

1. ASTM D3299

Applies to standards for Design Tanks large chop-hoop filament-wound tanks.

The Design Tanks Difference: ASTM D3299 allows the corrosion liner, which helps protect the tank from corrosive contents, to be included in the tank’s wall measurement. We build a heavier, more robust tank that always exceeds the standard for wall thickness. The result is a quality product with a very low incidence of tank failure. The customer receives a tank that exceeds the standard!

 

2. ASTM D4097

Applies to manufacturing standards for Design Tanks contact-molded small- and medium-sized tanks. Includes requirements for materials, properties, design, construction, dimension, tolerance, workmanship, and appearance.

The Design Tanks Difference: Design Tanks complies with the design strength requirements of ASTM D4097, utilizing a rigorous in-line and end-of-line quality control process plus testing of all resins and incoming materials.

 

3. ASME RTP-1

The Reinforced Thermoset Plastic (RTP) Corrosion Resistant Equipment Accreditation Program through the ASME (American Society of Mechanical Engineers) applies to guidelines on materials of construction, design, fabrication, quality control and inspection of vessels with design pressures up to 15 PSI (pounds per square inch). Certified fabricators can provide an RTP-1 stamp on qualifying tanks.

The Design Tanks Difference: While Design Tanks has elected not to seek certification at this time, we meet and exceed many of the RTP-1 standards without the additional costs associated with certification. For example, RTP-1 does not require a fabricator to keep materials in an environmentally controlled storage area prior to manufacturing. Design Tanks stores resins in a climate-controlled storage area to eliminate production variances related to temperature changes. All tanks are designed by an in-house professional engineer for design purposes, including a detailed QC program and a QC lab to keep tank production according to RTP-1 standards. Just two of the many ways Design Tanks rises above the fray without additional costs to our customers!
