Soft-soled shoes should be worn by workmen entering the tank. Nozzle Inside Diameter Up to 10 in. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. 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.
Where shape, thickness, or other restrictions preclude covering the edges with the preceding laminate, such cut edges and any machined? NOTE 20—A useful technique to check the cure of a non-molded surface of a polyester resin is as follows: Type II tanks may also require additional reinforcement.
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 thickness of the inner surface and interior layer 7. Applies to manufacturing standards for Design Tanks contact-molded small- and medium-sized tanks.
Included are requirements for materials, properties, design, construction, dimensions, tolerances, workmanship, and appearance. Your comments will receive careful consideration at a meeting of the responsible technical committee, which astj may attend.
Acceptable patterns of reinforcement placement are shown in Fig. 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.

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?
Asfm edition approved March 10, They do, however, require foundation cut-outs of the appropriate dimensions for the nozzle astn and size. The reinforcement shall then taper asgm the side wall over an additional length of 4 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. What are Design Tanks manufacturing standards?
The minimum thickness of the radiused section shall be equal to the combined thickness of the shell wall and the bottom. NOTE 21—The use of organic reinforcing materials may reduce the Barcol hardness readings without necessarily indicating undercure. Dimensions and Tolerances 8.
Where service conditions have not been evaluated, a suitable resin also may be selected by agreement between fabricator and purchaser. 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.
The reinforcement thickness shall be equal to the thickness of the head as calculated above. Rub a few drops of acetone on the laminate surface until it evaporates.
Special design consideration must be given to buckling of tank wall and heads, the hold-down lug system, and top and bottom knuckle requirements. We build a heavier, more robust tank xstm always exceeds the standard for wall thickness. The combined thickness of the inner surface and interior layer shall not be less than 0. Laminate Construction Requirements 7.
A superscript epsilon e indicates an editorial change since the last revision or reapproval. While Design Tanks has elected not to seek certification at this time, we meet and exceed many of satm RTP-1 standards without the additional costs associated with certification.
Do not attempt to lift tank by attaching to other?
All woven roving, nonwoven fabric, and surfacing mat shall be overlapped. When the inside laminate consists only of a corrosion barrier, the length of the laminate, hr shall be a minimum of 3 in. B Axial joint overlay widths shall 329 twice the width shown in table. NOTE 10—Tanks with signi?
The designations of these speci? Where woven roving is used, chopped-strand glass reinforcement shall be used as alternating and? The interior overlay shall present the same corrosion resistance to the? Each ply of mat or pass of chopped roving shall be well-rolled prior to the application of additional reinforcement. Do not attach lifting devices to any? Work Item s – proposed revisions of this standard.
For the convenience of the user, Committee D has highlighted those changes that may impact the use of this test method. NOTE 16—Special vent sizing consideration should be given to the numerous operating situations that could otherwise cause a positive or a negative pressure in a closed tank.
As an alternative, a minimum of two passes of chopped roving of minimum length 0.
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. NOTE 15—Tanks over 6 ft 1. This standard does not purport to address all of the safety concerns, if any, associated with its use. Nozzle may be penetrating type or? The use of woven roving is optional. 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.
