NOTE 5—The addition of pigment, dyes, or colorants may interfere with visual inspection of laminate quality. This section may include descriptions of the changes or the reasons for the changes, or both.

The combined thickness of the inner surface and interior layer shall not be less than 0. They do, however, require foundation cut-outs of the appropriate dimensions for the nozzle type and size. 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. A superscript epsilon e indicates an editorial change since the last revision or reapproval.

The customer receives a tank that exceeds the standard! 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. When contact-molded laminate joints are used to join hoop segments of the straight where: Prior to hoisting the top end, a suitable protection pad of material should be placed under the bottom pivot point of tank so that as the tank rises, the strain is taken on the pad.

For the convenience of the user, Committee D has highlighted those changes that may impact the use of this test method. Minimum vent size shall be sufficient to handle the? Each successive ply or pass of reinforcement shall be well-rolled prior to the application of additional reinforcement. In environments that attack glass, the use of an organic-?

The reinforcement shall then taper into the side wall over an additional length of 4 in. Rub a few drops of acetone on the laminate surface until it evaporates. Other techniques such as sprayed, wrapped, or overlaid?

Hold-down lugs should be grouted or shimmied to prevent d3299 loads being transferred to the tank shell. Typical plate type and conical type gussets are shown in Fig. 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.

Included are requirements for materials, properties, design, construction, dimensions, tolerances, workmanship, and x3299. This standard does not purport to address all of the safety concerns, if any, associated with its use. The corrosion-resistant barrier of the contact-molded portions of such nozzles shall be equivalent to the inner surface and interior layer 7.

This thickness, tr, may be applied to the outer or inner surfaces, or be divided between them as shown in Fig. Dimensions and Tolerances 8. This overlay shall be the equivalent of 7. PD t 5 2S 8 shell, or to join 3d299 bottom or top head to the shell, the thickness of d3929 structural joint overlay shall be determined by the following equation, but shall not be less than 3?
