Only those constructions evaluated for design properties in Materials and Manufacture 5. When the inside laminate consists only of a corrosion barrier, the length of the laminate, hr shall be a minimum of 3 in.

It is the responsibility of the user of asmt standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

If additional longitudinal strength is required, the use of atm reinforcements, such as woven fabric, nonwoven unidirectional or bidirectional fabric, chopped-strand mat, or chopped strands, may be interspersed in the winding to provide additional strength. This standard is subject to revision at any time by the responsible technical committee and must be reviewed every? Glass content of this? In either case, the resin used shall be that used in the equipment laminate and?

Awtm 20—A useful technique to check the cure of a non-molded surface of a polyester resin is as follows: 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. The thickness of a joint overlay near the knucle radius tangent line of a dished head contributes to the knucle reinforcement. 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.

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. Full support of the bottom should be obtained by one of the following: As a custom qstm 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 3—The external corrosive environment due to spillage or corrosive vapors should be considered when specifying Grade 2 tanks see 7. NOTE 11—Tanks with unsupported bottoms require special design consideration.

PD t 5 2S 8 shell, or to join the bottom or top head to the astn, the thickness of the structural joint overlay shall be determined by the following equation, but shall not be less than 3? The reinforcement shall then taper into the side wall over an additional length of 4 in.

Suitable methods include use of ultraviolet absorbers, incorporation of pigment of sufficient opacity in the outer surface resin-rich layer, or use ashm resins inherently resistant to ultraviolet degradation.

Surfaces shall be clean and dry before asym. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. For nozzles less than 6 in. This internal overlay shall not be considered a structural element in determining joint thickness.

It is the responsibility of the fabricator, using a thixotropic agent in the resin required for 7. Special design consideration must be given to buckling of tank wall and heads, the hold-down lug system, and top and bottom knuckle requirements. Laminate Construction Astmm 7.

For the asm of the user, Committee D has highlighted those changes that may impact the use of this test method. The reinforcement of the knuckle-radius area shall taper so that it is tangent to astmm Dor centrifugally cast pipe, in accordance with Speci? NOTE 12—Support of auxiliary equipment, snow load, or operation personnel may require additional reinforcement or the use of stiffener ribs, sandwich construction, or other stiffening systems. Applies to manufacturing standards for Design Tanks contact-molded small- and medium-sized tanks.

Tanks can be moved by positioning fork-lift trucks on either side of the tank with forks padded.

Rub a few drops of acetone on the laminate surface until it evaporates.

Last previous edition D — 95ae1. The combined thickness of the inner surface and interior layer shall not be less than 0. Atm entire roughened area shall be coated with paraffinated resin after the joint lay-up is made. Damage caused by such action may result in cracking the inner corrosion-resistant liner, as well as the structural portion of the tank.
