The Design Tanks Difference: Exceeding The Standards | Design Tanks
Design Requirements Design Requirements 6. 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. 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.
Full support of the bottom should be obtained by one of the following: NOTE 7—The selection of the particular chopped-strand mat is dependent upon the performance characteristics required of the? Contact-molded laminates shall satisfy the minimum property requirements listed in Speci? Absence of a designation of type required shall imply that Type I is adequate. 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.
Just two of the many ways Design Tanks rises above the fray without additional costs to our customers! NOTE 4—The addition of a thixotropic agent may reduce the resistance of many resin systems to certain corrosive chemical environments.
Current edition approved March 10, D — The shell taper shall not exceed 1? Applies to manufacturing standards for Design Tanks contact-molded small- and medium-sized tanks. For example, RTP-1 does not require a fabricator to keep materials in an environmentally controlled storage area prior to manufacturing.
The all-interior installation laminate placement is used only when the nozzle being installed has an integral conical gusset preventing application of an exterior laminate. 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.
In environments that attack glass, the use of an aztm
When the inside laminate consists only of a corrosion barrier, the length of the laminate, hr shall be a minimum of 3 in. Awtm woven roving is used, chopped-strand glass reinforcement shall be used as alternating and? Type II tanks may also require additional reinforcement. The result is a quality product with a very low incidence of tank failure. NOTE 21—The use of organic reinforcing materials may reduce the Barcol hardness readings without necessarily indicating undercure. There is no known ISO equivalent to this standard.
Typical plate type and conical type gussets are shown in Fig. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but ashm not provided as part of the standard. Do not attach lifting devices to any? The tank shall be secured to the cradles or skid so that there can be no movement of the tank in relation to the skid or cradle under normal handling. The design number and attachment of such lugs is the responsibility of the fabricator, based on the wind, seismic, and other loads speci?
NOTE 18—When tr is calculated to be 1?
The use of woven roving is optional. Surfaces shall be aztm and dry before lay-up. NOTE 10—Tanks with signi? D Flange thickness shall be at least equal to local vessel thickness.
The intent of these requirements is to avoid orienting joints in reinforcing asgm perpendicular to the maximum load-bearing direction circumferential. Originally published as D — Where service conditions have not been evaluated, a suitable resin also may be selected by agreement between fabricator and purchaser.
The entire roughened area shall be coated with paraffinated resin after the joint lay-up is made. Individual reprints single or ashm copies of this standard may be obtained by contacting ASTM at the above address or at phonefaxor service astm. B Axial joint overlay widths shall be twice the width shown in aztm. Obtain asmt test sample by carefully splitting these combined areas from the structural layer.
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.
This overlay shall be the equivalent of 7. The corrosion-resistant barrier of the nozzle shall be at least equivalent to the inner surface and interior layer 7. This abstract is a brief summary of the referenced standard.

Where ladders are used inside and outsideall points of contact with the astmm should be cushioned to protect the surface from scratching or point loading.
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.
