NOTE 12—Support of auxiliary equipment, snow load, or operation personnel 32999 require additional reinforcement or the use of stiffener ribs, sandwich construction, or other stiffening systems. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

In addition, this clearance shall not be less than the shear distance required for proper installation of the nozzle see 7.

Surfaces shall be clean and dry before lay-up. NOTE 8—The use of an accepted analytical technique, such as laminated plate theory LPTfor design and analysis of composite vessels may predict stresses, strains, and strength on a ply-by-ply basis, given some basic lamina properties.


Dimensions and Tolerances 8. If damage has occurred, a claim should be? If additional longitudinal strength is required, the use of other reinforcements, such as woven fabric, nonwoven astn or bidirectional fabric, chopped-strand mat, or chopped strands, may ast interspersed in the winding to provide additional strength.

ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up aetm date. Current edition approved March 10, 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 aetm. 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.

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. Methods of manufacture that incorporate stiffening bands as a means of knuckle stabilization, are permissible alternatives by agreement between purchaser and fabricator, provided the fabricator can document the validity of the design.


NOTE 15—Tanks over 6 ft 1. 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 twice the width shown in table. This standard is subject to revision at any time by the responsible technical committee and must be reviewed every?

Special design consideration must be given to buckling astn tank wall and heads, the hold-down lug system, and top and bottom knuckle requirements. Only those constructions evaluated for design properties in 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. Fluid level in the tank is an important consideration in the analysis.

This overlay shall be the equivalent of 7.

NOTE 4—The addition of a thixotropic agent may reduce the resistance of many resin systems to certain corrosive chemical environments.
