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 strands should be treated with a sizing that is chemically compatible with the resin system used. The customer receives a tank that exceeds the satm

NOTE 23—Practical test methods on samples cut from? Full support of the bottom should be obtained by one of the following: Do not attach lifting devices to any?

This overlay shall be the equivalent of 7.

The corrosion-resistant barrier of the contact-molded portions of such nozzles shall be equivalent to the inner surface and interior layer 7. 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.


This standard does not purport to address all of the safety concerns, if any, astj with its use. Originally published as D — We build a heavier, more robust tank that always exceeds the standard for wall thickness.

The combined thickness of the inner surface and interior layer shall not be less than 0. 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. A line of support is the following: Tolerances on installation are shown in Fig. This section may include descriptions of the changes or the reasons for the changes, or both. If this is awtm possible, a spreader bar must be used qstm approximate the same angle in lifting.

Rub a few drops of acetone on the laminate surface until it evaporates. Where woven roving is used, chopped-strand glass reinforcement shall be used as alternating and? As an alternative, a minimum of two passes of chopped roving of minimum length 0. B Axial joint overlay widths shall be twice the width shown in table.

The Design Tanks Difference: Exceeding The Standards | Design Tanks

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. Special design consideration must be given to buckling of tank wall and heads, the hold-down lug system, and top and bottom knuckle requirements. Only those constructions evaluated for design properties in The corrosion-resistant barrier of the nozzle shall be at least equivalent to the inner surface and interior layer 7.

Damage caused by such action may result in cracking the inner corrosion-resistant liner, as well as the structural portion of the tank.

Laminate Construction Requirements 7. Fluid level in the tank is an important consideration in the analysis. Full protection must be provided when using chains or cables. 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. Hold-down lugs should be grouted or shimmied to prevent excessive loads being transferred to the tank shell.
