This standard has been approved for use by agencies of the Department of Defense. The use of woven roving is optional.

NOTE 6—Because the addition of? Type II tanks may also require additional reinforcement.

This thickness, tr, may be applied to the outer or inner surfaces, or be divided between them as shown in Fig. The thickness of a joint overlay near the knucle radius tangent line of a dished head contributes to the knucle reinforcement. This specification covers cylindrical corrosion-resistant tanks made of commercial-grade glass-fiber-reinforced polyester or vinylester thermoset resin fabricated by filament winding for above-ground vertical installation, to contain aggressive chemicals at atmospheric pressure as classified herein.

In environments that attack glass, the use of an organic-? NOTE 18—When tr is calculated to be 1?

32999 Larger nozzles, subject to superimposed mechanical forces, require special consideration. Design Tanks complies with the design strength requirements of ASTM Dutilizing a rigorous in-line and end-of-line quality control process plus testing of all resins and incoming materials. A superscript epsilon e indicates an editorial change since the last revision or reapproval.

For Elliptical Bottom Head: Last previous edition D — 95ae1. They do, however, require foundation cut-outs of the appropriate dimensions for the nozzle type and size. asym


D — The Design Tanks Difference: Property 18 Thickness, in. Work Item s – proposed revisions of this standard. Contact-molded laminates shall satisfy the minimum property requirements listed in Speci?

As a custom manufacturer specializing in axtm 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. Do not attach lifting devices to any? Suitable methods include use of ultraviolet absorbers, incorporation of pigment of sufficient opacity in the outer surface resin-rich layer, or use of resins inherently resistant to ultraviolet degradation.

Design Requirements Design Requirements 6. A number in parentheses indicates the year of last reapproval. NOTE 22—Barcol hardness values may vary when tests are conducted at temperatures that differ from those shown in The reinforcement thickness shall be equal to the thickness of the head as calculated above.

The cradles or skid shall be padded and secured to the bed of the vehicle in such a manner that will prevent damage to the tank with normal handling.

When the inside laminate consists only of atsm corrosion barrier, the length of the laminate, hr shall be a minimum of 3 in. The corrosion-resistant barrier of the nozzle shall be at least equivalent to the inner surface and interior layer 7.

The bottom laminate surface shall be a hand-work? Design Tanks stores resins in a climate-controlled storage area to eliminate production variances related to temperature changes. Asgm specification does not address the design of vessels intended for pressure above atmospheric, vacuum conditions, except as classified herein, or vessels intended for use with liquids heated above their flash points.


NOTE 20—A useful technique to check the cure of a non-molded surface of a polyester resin is as follows: 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. In addition, this clearance shall not be less than the shear distance required for proper installation of the nozzle see 7.

Obtain a test sample by carefully splitting these combined areas from the structural layer. Full support of the bottom aztm be obtained by one of the following: The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.

The reinforcement of the knuckle-radius area shall taper so that it is tangent to the? NOTE 4—The addition of a thixotropic agent may reduce the resistance of many resin systems to certain corrosive chemical environments. NOTE 2—Gaskets shall be 1?

Where service conditions have not been evaluated, a suitable resin also may be selected ashm agreement between fabricator and purchaser. In either case, the resin used shall be that used in the equipment laminate and? Nozzle Inside Diameter Up to 10 in.

Applies to manufacturing standards for Design Tanks contact-molded small- and medium-sized tanks. The shell taper shall not exceed 1?

The entire roughened area shall be coated with paraffinated resin after joint overlay is made.
