Applies to manufacturing standards for Design Tanks contact-molded small- and medium-sized tanks. The customer receives a tank ast exceeds the standard! Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. 4907 tanks are classified as type I and II according to the operating pressure xstm vacuum levels, and the safety factor required for external pressure. The tanks are further classified as grade 1 and 2 according to the generic types of thermoset resin.

The reinforcement should be a chopped-strand mat, a nonwoven biaxial or unidirectal fabric, a woven roving, or a surface mat. The values given in 497 are provided for information purposes only.

The Design Tanks Difference: Materials shall be tested and the individual grades shall conform to specified values of design requirements such as straight shell, external pressure, top head, bottom head, open-top tanks, joints, fittings, hold-down lugs, and lifting lugs; laminate construction requirements such as structural tank, joints, and fittings and accessories; and other requirements such as physical properties, chemical resistance of resin, glass content, tensile strength, flexural properties and degree of cure.

Included are requirements for materials, properties, design, construction, dimensions, tolerances, workmanship, and appearance. There is no known ISO equivalent to this standard.


Includes requirements for materials, properties, design, construction, dimension, tolerance, workmanship, and appearance. The dimensions and tolerances, as well as the workmanship, finish and appearance are also detailed. The resin used shall be a commercial grade, corrosion-resistant thermoset. Certified fabricators can provide an RTP-1 stamp on qualifying tanks. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application.

The Design Tanks Difference: Exceeding The Standards | Design Tanks

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. Link to Active This link will always route to the current Active version of the standard.

Design Tanks complies with the design strength requirements 40977 ASTM Dutilizing a rigorous in-line and end-of-line quality control process plus testing of all resins and incoming materials.

Just two of the many ways Design Tanks rises above the fray without additional costs to our customers! For example, RTP-1 does not require a fabricator to keep materials in an environmentally controlled storage area prior to manufacturing. 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.

It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. We build a heavier, more robust tank that always exceeds the standard for wall thickness. Design Tanks stores resins in a climate-controlled storage area to 40097 production variances related to temperature changes.


This standard does astk purport to address all of the safety concerns, if any, associated with its use. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date. Work Item s – proposed revisions of this standard.

ASME RTP-1 As a custom manufacturer specializing in meeting s unique needs of our customers, our exposure to these different standards is much higher than for the manufacturer that produces a cookie cutter tank. This specification does not cover the design of vessels intended for pressure above hydrostatic, vacuum conditions, except as classified herein, or vessels intended for use with liquids heated above their flash points.

This abstract is a brief summary of the referenced standard. Historical Version s – view previous versions of standard. The three predominant standards today that relate to fiberglass tanks and vessels are: This specification covers cylindrical tanks fabricated by contact molding for above-ground vertical installation, to contain aggressive chemicals at essentially atmospheric pressure, and made of a commercial-grade polyester or vinyl ester, resin.

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. The result is a quality adtm with a very low incidence of tank failure.
