Last previous edition D — 95ae1. This standard has been approved for use by agencies of the Department of Defense. The corrosion-resistant barrier of the nozzle shall be at least equivalent to the inner surface and interior layer 7. 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.

Where woven roving is used, chopped-strand glass reinforcement shall be used as alternating and? Historical Version astj – view previous versions of standard.

NOTE 20—A useful technique to check the cure of a non-molded surface of asmt polyester resin is as follows: Larger nozzles, subject to superimposed mechanical forces, require special consideration.

This standard does not purport to address all of the safety concerns, if any, associated with its use. Nozzle Inside Diameter Up to 10 in. Obtain a test sample by carefully splitting these combined areas from the structural layer. 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.

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

D — Just two of the many ways Design Tanks rises above the fray without additional costs to our customers! Soft-soled shoes should be worn by workmen entering the tank.

Applies to manufacturing standards for Design Tanks contact-molded small- and medium-sized tanks.

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.

Work Item s – proposed revisions of this standard. Included are requirements for materials, properties, design, construction, dimensions, tolerances, workmanship, and appearance. Hold-down lugs should be grouted or shimmied to prevent excessive loads being transferred to the tank shell.

Rub a few drops ashm acetone on the laminate surface until it evaporates. The glass content of the separated sample shall be determined in accordance with Test Method D The hoist wire should be connected to the top lifting lugs, and the tank should be raised carefully, using guide ropes to prevent sudden swinging. Where ladders are used inside and outsideall points of contact with the tank should be cushioned to protect the surface from scratching or point loading.

This section may include descriptions of the changes or the reasons for the changes, or both.

We build a heavier, more robust tank that always exceeds the standard for wall thickness. The reinforcement awtm the knuckle-radius area shall taper so that it is tangent to the? Tanks can be moved by positioning fork-lift trucks on either side of the tank with forks padded. Workmanship, Finish, and Appearance 8.

Hoisting equipment operators should attach a guide line to prevent tank from swinging out of control. Nozzle may be penetrating type or? Certified fabricators can provide an RTP-1 stamp asym qualifying tanks. Absence of a designation of type required shall imply that Type I is adequate. NOTE 10—Tanks with signi?

Other test methods for determination of hoop properties may be used when the fabricator can verify the validity of the selected method. Full protection must be provided when using chains or cables. This specification does not address the design of vessels intended for pressure above atmospheric, vacuum conditions, except as classified herein, or vessels intended for use with liquids heated above aetm flash points. 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.

Acceptable patterns of reinforcement placement are shown in Fig.

Only those constructions evaluated for design properties in This thickness, tr, may be applied to the outer or inner surfaces, or be divided between them as shown in Fig. This specification covers cylindrical corrosion-resistant tanks made of commercial-grade glass-fiber-reinforced polyester or vinylester thermoset dd fabricated by filament winding for above-ground vertical installation, to contain aggressive chemicals at atmospheric pressure asstm classified herein.

This overlay shall be the equivalent of 7. Where service conditions have not been evaluated, a suitable resin also may be selected by agreement between fabricator and purchaser.

The interior overlay shall present the same corrosion resistance to the?
