NOTE 20—A useful technique to check the cure of a non-molded surface of a polyester resin is as follows: In either case, the resin used shall be that used in the equipment laminate and? The entire roughened area shall be coated with paraffinated resin after joint overlay is made.
Where service conditions have not been evaluated, a suitable resin also may be selected by agreement between fabricator and purchaser. If damage has occurred, a claim should be? Users of this standard are expressly advised that determination of the validity of any such patent rights, and the risk of infringement of such rights, are entirely their own responsibility. The corrosion-resistant barrier of the nozzle shall be at least equivalent to the inner surface and interior layer 7.
PD t 5 2S 8 shell, or to join the bottom or top head to the shell, the thickness of the structural joint overlay shall be determined by the following equation, but shall not be less than 3? A number in parentheses indicates the year of last reapproval.
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. Work Item s – proposed revisions of this standard. The shell taper shall not exceed 1? Instrument calibration and method shall be as described in Test Method D Link to Active This link will always route to the current Active version of the standard.
The strands should be treated with a sizing that is chemically compatible with the resin system used. Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters. Hoisting equipment operators should attach a guide line to prevent tank from swinging out of control. D Flange thickness shall be at least equal to local vessel thickness.
There is no known ISO equivalent to this standard. Do not attempt to lift tank by attaching to other?
The interior overlay shall present the same corrosion resistance to the? The three predominant standards today that relate to fiberglass tanks and vessels are: The design number and attachment of such 3929 is the responsibility of the fabricator, based on the wind, seismic, and other loads speci?
Type II tanks may also require additional reinforcement. 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. Certified fabricators can provide an RTP-1 stamp on qualifying tanks. Each ply of mat or pass of chopped roving shall be well-rolled prior to the application of additional reinforcement.
The Design Tanks Difference: Plate gussets, where needed, shall be evenly spaced around the nozzle and are to be added after complete assembly by the nozzle on the shell.

Property 18 Thickness, in. NOTE 13—This requirement is not intended to exclude the use of drain nozzles which are commonly used at the bottom of the side shell. For nozzles less than 6 in. If additional longitudinal strength is required, the use of other reinforcements, such as woven fabric, nonwoven unidirectional or bidirectional fabric, chopped-strand mat, or chopped strands, may be interspersed in the winding to provide additional strength.

Dor centrifugally cast pipe, in accordance with Speci? Nozzle may be penetrating type or? Damage caused by such action may result in cracking the inner corrosion-resistant liner, as well as the structural portion of the tank.
Originally published as D — Minimum vent size shall be sufficient to handle the? Asfm 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. NOTE 9—Tanks for x outdoors shall be designed for the effect of wind loading and other environmental factors in accordance with sound design practice, including tank buckling analysis. The minimum thickness of the radiused section shall be equal to the combined thickness of the shell wall and the bottom.
Fluid level in the tank is an important consideration in the analysis. Workmanship, Finish, and Appearance 8. F 22—Barcol hardness values may vary when tests are conducted at temperatures that differ from those shown in NOTE 7—The selection of the particular chopped-strand mat is dependent upon the performance characteristics required of the?
B Axial joint overlay widths shall be asgm the width shown in table. Surfaces shall be clean and dry before lay-up.
