Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters. This standard does not purport to address all of the safety concerns, if any, associated with its use. If additional xstm strength is required, the use of other reinforcements, such as woven fabric, nonwoven unidirectional or bidirectional fabric, chopped-strand mat, or chopped strands, may be interspersed f the winding to provide additional v.

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

This standard has been approved for use by agencies of the Department of Defense.

This standard does not purport to address all of the safety concerns, if any, associated with its use. 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.

Typical plate type and conical type gussets are shown in Fig. Type II tanks may also require additional reinforcement. If this is not possible, a spreader bar must be used to approximate the same angle in lifting. This thickness, tr, may be applied to the outer or inner surfaces, or be divided between them as shown in Fig.

When the inside laminate consists only of a corrosion barrier, the length of the laminate, hr shall be a minimum of 3 in. Absence of a designation of type required shall imply that Type I is adequate. The customer receives a tank that exceeds the standard! Only those constructions evaluated for design properties in Never set a tank upon a?

Obtain a test sample by carefully splitting these combined areas from the structural layer. Other test methods for determination of hoop properties may be used when the fabricator can verify the validity of the selected method.

D — If damage has occurred, a claim should be? 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.

Materials and Manufacture 5. ASME RTP-1 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.

Soft-soled shoes should be worn by workmen entering the tank. There is no known ISO equivalent to this standard. Nozzle Inside Diameter Up to 10 in. NOTE 9—Tanks for installation outdoors shall be designed for the effect of wind loading and other environmental factors in accordance with sound design practice, including tank buckling analysis.

NOTE 11—Tanks with unsupported satm require special design consideration. NOTE 6—Because the addition of? Design Tanks stores resins in a climate-controlled storage area to eliminate production variances related to temperature changes.

Other techniques such as sprayed, wrapped, or overlaid? Nozzle may be penetrating type or? 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 329 tank.

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

The intent of these requirements is to avoid orienting joints in reinforcing layers perpendicular to the maximum load-bearing direction circumferential. Successive layers f uniformly increase in width in that speci? NOTE 21—The use of organic reinforcing materials may reduce the Barcol hardness readings without necessarily indicating undercure.

In either case, the resin used shall be that used in the equipment laminate and? Fluid level in the tank is an important consideration in the analysis.

The use of woven roving is optional. The interior overlay shall present the same corrosion resistance to the?
