8. BASIC MATERIALS

Resin: The resin used shall be a commercial-grade, corrosion-resistant thermoset that has either been evaluated ina laminate or has been determined by previous documented service to be acceptable for the service conditions.

The resin shall contain no pigment, dyes, colorants, or filler, except as follows:

a. A thixotropic agent that does not interfere with visual inspection of laminate quality, or with the requiredcorrosion resistance of the laminate, may be added for viscosity control.

b. Resin pastes used to fill crevices before overlay

c. Ultaviolet absorbers may be added to the exterior surface for improved weather resistance.

d. Antimony compounds or other fire-retardant agents may be added for improved weather resistance

Chopped Strand Mat: Chopped strand mat shall be constructed from chopped commercial-grade E-typeglass strands bonded together using a binder. The strands should be treated with a sizing that is chemicallycompatible with the resin used.

Continuous Roving: Continuous roving shall be a commercial-grade of E-type glass fiber with a sizingthat is chemically compatible with the resin system used.

Woven Roving: Woven roving shall be in accordance with ASTM D2150.

Surfacing Mat: The reinforcement used for the inner surface shall be either a commercial-grade chemicalresistant glass surface mat or an organic-fiber surface mat. In environments that attack glass, the use of anorganic-fiber surface mat is required.

9. DESIGN REQUIREMENTS

Filament Wound Laminates: The maximum allowable stress of the total laminate shall be limited by theallowable movement of the tank wall when filled with fluid. Tanks for installation outdoors shall bedesigned for the effect of wind loading and other environmental factors. Tanks with significant physicalloadings, other than fluid head (such as side mounted equipment or agitation) shall be given special designconsideration.

The allowable strain of the tank wall shall not exceed 0.0010 in. at 70F. Minimum thickness of the tankshall be 0.180 in.

Contact Molded Laminates: Portions of the tank such as joints, heads, nozzles, and supports may befabricated by contact molding. Contact-molded laminates shall satisfy the minimum property requirementslisted in ASTM C 582-Table 1.

Top Head: The top head, regardless of shape, shall be able to support a single 250-lbf load on a 4 by 4-in.area without damage and with a maximum deflection of 1/2% of the tank diameter at the area the load isapplied. Support of auxiliary equipment, snow load or operation personnel may require additionalreinforcement or the use of stiffener ribs, sandwich construction, or other stiffening systems. Minimumthickness shall be 0.1876 in.

4.

Bottom Head: The minimum thickness for a fully supported flat-bottom head shall be as follows:

3/16 in. for 2 to 6 ft diameter1/4 in. for 6 to 12 ft diameter, and3/8 in. for over 12 ft diameter

The radius of the bottom knuckle of a flat-bottom tank shall be not less than 1 in. on tanks 4 ft. or smaller indiameter and 1.5 in. on tanks larger than 4 ft. diameter. The minimum thickness of the radiused section shallbe equal to the combined thickness of the shell wall and the bottom. The reinforcement of the knuckle-areashall taper so that it is tangent to the flat bottom, and shall not extend beyond the tangent line onto the tankbottom, unless methods of manufacture are used that maintain flat-bottom configuration, and shall extend up thevertical tank wall a minimum of 8 in. on tanks up to 4 ft. in diameter and 12 in. on tanks over 4 ft. in diameter.The reinforcement shall then taper into the side wall over an additional length of 4 in.

The tank bottom shall not have variations from a nominally flat plane that would prevent uniform contact of theentire bottom surface with a properly prepared flat support surface when the tank is filled with liquid. Thebottom laminate surface shall be a hand-work finish, and shall have no excessive laminate projections thatwould prevent uniform contact with a properly prepared flat support surface when the tank is filled with liquid.Deflection of the flat bottom when the tank is empty, commonly known as “oil canning,” is permissible as longas these requirements are met.

The thickness of an elevated-dished bottom, suitable for supporting the weight of the fluid head, shall be no lessthan 3/16 in.

For dished heads subject to internal loading, the knuckle radius shall be externally reinforced. Thereinforcement thickness shall be equal to the thickness of the head. The thickness of a joint overlay near theknuckle radius tangent line of a dished head contributes to the knuckle reinforcement.

The dished-bottom head shall have a radius of curvature that is equal to or less than the inside diameter of thetank straight shell, and knuckle radius of at least 6% of the diameter of the head.

Open-Top Tanks: The top edge of open top tanks shall have a horizontal reinforcing flange or other means ofreinforcement sufficiently rigid to maintain the shape of the tank after installation, such as stiffener ribs.

Joints: The cured resin surfaces to be overlaid shall be roughened using 36 or courser grit abrasive media andshall extend beyond the lay-up area so that no reinforcement is applied to an unroughened surface. Surfacesshall be clean and dry before lay-up. The entire roughened area shall be coated with paraffinated resin after thejoint lay-up is made.

Joints between tank-wall sections shall be over-wound to thickness, or may be overlaid by a contact-moldedlaminate. When contact-molded laminate joints are used to join hoop segments of the straight shell, or to jointhe bottom or top head to the shell, the thickness of the structural joint overlay shall not be less than 3/16 in.

The corrosion-resistant barrier component of the joint shall be formed in the same manner as the inner surfaceand the interior layer and the minimum overlay width shall be 4 in. This internal overlay shall not beconsidered a structural element in determining joint thickness.

The thickness of a joint near the bottom tangent line shall not be considered to contribute to the knucklereinforcement, but shall be additive thereto.

Fittings: The more common method of fabricating nozzles is by contact molding both the nozzle neck andflange to the dimensions shown in Specification D5421 and as listed in the table below. The corrosion-resistantbarrier of the nozzle shall be at least equivalent to the inner surface and interior layer and shall be fabricatedfrom the same resin as the tank head or shell to which it is attached.

5.

All measurements in inches

Nozzles 4 in and smaller shall be supported by a suitable gusseting technique, using plate gussets or conicalgussets. Plate gussets, where needed, shall be evenly spaced around the nozzle and are to be added aftercomplete assembly by the nozzle on the shell. Larger nozzles, subject to superimposed mechanical forces,require special consideration.

Manways installed in top heads may be of the flanged or nonflanged design, as agreed upon between thefabricator and purchaser. Vents: Tanks that discharge freely into the atmosphere must be provided in all Type I closed-top tanks.Minimum vent size shall be sufficient to handle the flow displacement of all combined inlet or outlet nozzleswithout creating any pressure above atmospheric, or any vacuum condition.

Special vent sizing consideration should be given to the numerous operating situations that could otherwisecause a positive or a negative pressure in a closed tank. Since overfilling a closed tank with the vent on the topcan cause the tank to be over-pressured, a suitably sized overflow, properly located, or other appropriateprotection, may be required to prevent over-pressurizing the tank.

Type II tanks shall be designed to withstand the specified positive or negative pressures not to exceed 14 in. ofwater. Special design consideration must be given to buckling of tank wall and heads, the hold-down lugsystem, and top and bottom knuckle requirements. Fluid level in the tank is an important consideration in theanalysis.

Flat-bottom Type II tanks must have all hold-down lugs properly secured to the foundation, in accordance withthe fabricator’s recommendations for the design of the lugs used and for the tank installation and operation.

Hold-Down Lugs: Hold-down lugs shall be a requirement on all tanks for outdoor service, on all Type II tanks,and on tanks subject to seismic loads or vibrations. The design number and attachment of such lugs is theresponsibility of the fabricator, based on wind, seismic, and other loads specified by the purchaser.

Hold-down lugs shall be placed on the tank in such a way that they do not protrude below the bottom surface ofthe tank.

Lifting Lugs: Lifting lugs or other provisions for lifting tanks shall be provided for tanks over 500 lbs. inweight.

10. LAMINATE CONSTRUCTION

Tanks shall be hand lay-up, spray-up, or filament wound construction in accordance with the applicablegoverning standards. The finished laminate shall be constructed using either a single or dual resin system andshall not contain colorants, dyes, fillers or pigments.

Structural Tank: The laminate comprising the structural tank (bottom, shell, top head) shall consist of acorrosion-resistant barrier comprised of an inner surface, interior layer, and a structural layer.

Inner Surface: The inner surface exposed to the chemical environment shall consist of a resin rich layer 0.010to 0.020 in. thick, reinforced with a suitable chemical-resistant glass fiber surface mat or with an organic fibersurface mat.

Interior Layer: The inner surface layer exposed to the corrosive environment shall be followed with a layercomposed of resin, reinforced only with non-continuous glass-fiber strands applied in a minimum of two pliesof chopped-strand mat. As an alternative, a minimum of two pass of chopped roving of minimum length of 0.5in. to a maximum length of 2.0 in. shall be applied uniformly. Each ply of mat or pass of chopped roving shallbe well-rolled prior to the application of additional reinforcement. The combined thickness of the inner surfaceand interior layer shall not be less than 0.10 in.

Glass content of the inner liner and the interior layer combined shall be 27 +/- 5% by weight.

The degree of cure of the laminate shall be such as to exhibit a Barcol hardness on the inner surface of at least90% of the resin manufacturer’s minimum specified hardness for the cured resin.

Structural Layer:

Filament Wound: Subsequent reinforcement shall be continuous-strand roving. The thickness of the filament-wound portion of the tank shell may be varied with tank height (tapered-wall construction). If additionallongitudinal strength is required, the use of other reinforcement such as woven fabric, chopped-strand mat, orchopped strands, may be interspersed in the winding to provide additional strength. Glass content of thisfilament-wound structural layer shall be 50 to 80% by weight.

Contact-Molded Structural layer in Top and Bottom Heads: Subsequent reinforcement shall be comprised of1.5 oz/ft chopped-strand mat or equivalent weight of chopped roving, or shall be comprised of chopped-strandmat or chopped roving and such additional number of alternating plies of 24 oz/yd woven roving 18 oz/yd non-woven biaxial fabric to a thickness as required to meet the physical properties that are used for the design.Each successive ply or pass of reinforcement shall be well-rolled prior to the application of additionalreinforcement. Where woven roving is used, chopped-strand glass reinforcement shall be used as alternatingand final layers. All woven roving and surfacing mat shall be overlapped. Laps in subsequent layers shall bestaggered at least 2.25 in. from laps in the preceding layer.

When the outer surface of this structural layer is to be subject to spillage or a corrosive environment, a resin-rich layer, shall be applied over the final layer of reinforcement.

Tanks used for outdoor service shall incorporate provisions to minimize ultraviolet degradation. A suitablemethod includes the use of a 5 mil thickness of exterior gel coat. The entire tank shell shall be lightly sandedto allow the gel-coat finish to adhere properly. Since pigmentation makes inspection difficult, the gel-coat shallbe applied after the structural layer has cured and a visual inspection is performed.

Where air-inhibited resin is exposed to air, full surface cure of the inner surface shall be obtained by coatingsuch surface with a coat of resin containing 0.2 to 0.6% paraffin wax. The acetone sensitivity test is used tocheck surface cure.

Joints: The width of the first layer shall be 3 in. minimum. Successive layers shall uniformly increase in widthto form a smooth contour laminate that is centered on the joint +/- 1/2 in.

A highly filled resin paste shall be placed in the crevices between joined pieces, leaving a smooth surface forlay-up.

The cured resin surfaces of parts to be joined shall be roughened using 36 or coarser abrasive media to exposeglass fibers. This roughened area shall extend beyond the lay-up areas so that no reinforcement is applied to anunprepared surface. Surfaces shall be clean and dry before lay-up. The entire roughened area shall be coatedwith paraffinated resin after joint overlay is made.

The interior overlay of a joint shall consist of a minimum of two plies of 1.5 oz/ft chopped strand matreinforcement, followed by a resin-rich layer reinforced with surfacing mat.

The outer structural overlay of a joint shall be centered on the joint and shall be finished. 7.

Fittings and Accessories: The surfaces of fittings, tank accessories, and the laminates required for theirinstallation that are exposed to the corrosive media shall be constructed in accordance with this specificationexcept for those fitting surfaces which are made by manufacturing processes other than contact molding.

The cut edges of all laminates exposed to the chemical environment shall be sealed with a laminate. Whereshape, thickness, or other restrictions preclude covering the edges with laminate, such cut edges and anymachined flange faces shall be at least coated with resin. In either case, the resin used shall be the same used inthe equipment laminate.

Nozzle and Manway Installation: Flanged nozzles may be installed with the pipe stub flush inside the tankshell or projecting inside the tank.

Nozzle Projection: The installed nozzle shall maintain a clearance of 3 in. between the back of the flange andthe exterior of the cutout opening reinforcement. In addition, this clearance shall not be less than the sheardistance required for proper installation of the nozzle.

Cutout Reinforcement Laminate: When a vessel shell or head is cut in an area bearing hydrostatic pressure,the cutout shall be reinforced on a circular area concentric with the cutout.

Cutout Reinforcement Diameter: The outer diameter of the cutout reinforcing laminate, shall not be less thantwo times the nominal nozzle diameter. For nozzles less than 6 in. in diameter, the minimum cutoutreinforcement diameter shall be the nominal nozzle size plus 6 in.

Cutout Reinforcement Thickness: The thickness of the cutout reinforcement laminate for nozzles installed incylindrical shells or dished heads shall be determined by nozzle and tank size.

When reinforcing materials are cut to facilitate placement around and installed nozzle, joints in successivereinforcing layers should be staggered to avoid overlapping and (on cylindrical shell installation) shall not beplaced so they are parallel the axis of the tank. The intent of this requirement is to avoid orienting joints inreinforcing layers perpendicular to the maximum load-bearing direction.

Nozzle Installation Laminates: The all interior installation laminate placement is used only when the nozzlebeing installed has an integral conical gusset preventing application of an exterior laminate.

Installation Laminate Thickness: The inside and outside installation thicknesses combined shall be at least asthick as the nozzle neck.

Inside Installation Laminate Construction: The inside installation laminate shall be constructed using onlynoncontinuous glass reinforcements, except that when woven roving is included to strengthen the laminate, itshall be preceded and followed by a layer of 1 1/2 oz mat and then covered with a laminate. When the insidelaminate consists only of a corrosion barrier, the length of the laminate shall be a minimum of 3 in. or thenominal radius of the nozzle.

Installation Laminate Lengths: The length of the outside laminate and the inside laminate shall each be equalto the shear length, based on the thickness of the individual laminates.

In the nozzle installations where the installation overlay is installed before the cutout reinforcement has fullycured, that portion of the overlay which extended into the tank shell may be considered to become a part of thecutout reinforcement laminate if the installation laminate length is extended to the required cutoutreinforcement diameter.

Monolithic Installation: The total bond thickness shall be the greater of either the cutout reinforcementthickness or the outside bond thickness.

Gussets: If plate or conical gussets are used to stiffen the installed nozzle, gusset installation laminates are inaddition the nozzle installation laminates.

Location of Cutouts on the Shell: For cutouts made within 6 in. of the knuckle radius area of a head or within6 in. of a shell-to-head joint, additional hole-cutout reinforcement is required, unless the area of installation isat a point within the vessel that is not exposed to hydrostatic pressure.

All nozzles and manways shall be installed in accordance with ASTM specification. The interior overlay shallpresent the same corrosion resistance to the fluid.

8.

11. DIMENSIONS AND TOLERANCES

Standard tank diameters are based on internal measurements with the tank in the vertical position.

Tolerance on the inside diameter, including out-of-roundness, shall be +/- 1%.

Shell taper shall be additive to the figure used for the tank diameter. Shell taper shall not exceed 1/2 degree perside.

Tolerance on overall tank height shall be 1/2%, but shall not exceed +/- 1/2 in.

Nozzle flange faces shall be perpendicular to the axis of the pipe and shall be flat within +/- 1/32 in. through 18in. nozzle size and 1/16 in. for large nozzle sizes.

The standard orientation of flanges shall provide bolt holes straddling the normal centerlines of the tank. Boltholes of flanges located on the tank top or bottom, shall straddle the principal centerline of the vessel or linesparallel to it.

12. WORKMANSHIP, FINISH and APPEARANCE

The minimum acceptable for workmanship and finish of the finished laminate shall conform to the requirementsspecified in Section 9 of Specification C 582.

13. REQUIRMENTS

Degree of Cure: Degree of cure of the laminate shall be found by determining the Barcol hardness.

A useful technique to check the cure of a non-molded surface of a polyester resin is as follows: Rub a fewdrops of acetone on the laminate surface until it evaporates. If the surface becomes softened or tacky, it isindication of under cure.

The use of organic reinforcing materials may reduce the Barcol readings without necessarily indicating undercure.

Barcol hardness values may vary upon temperature.

14. PRODUCT MARKING

The tank shall be marked to identify the producer, date of manufacture, capacity, all resins used, inner surfacereinforcements, specific gravity, design temperature, and the words “Pressure-Atmospheric,” or the operatingpressure and vacuum, shall be imprinted on the tank.

Additional marking requirements may be needed for compliance with local codes. It is the responsibility of thepurchaser/user to specify additional labeling requirements for the vessel, such as liquid content, operating andsafety instructions, and any other warnings necessitated by local codes.

OC® SURFACING VEIL PRODUCT SELECTIONThicknessOC® Surfacing Veils are generally selected first based on thickness in the composite part.The standard forcorrosion resistance and surface enhancement is 10 mil(0.5 mm). Thicker veils are selected for enhanced surfaceprint blocking or added corrosion protection through athicker resin-rich surface layer. Generally the thinnest layer that gives sufficient surface properties is chosen.For closed molding and infusion process with higher glasscontent in the laminate, thicker veils are often required to mask the substrate reinforcements.

Solubility and Binder SelectionThe selection of the appropriate binder is based on thecomposite process and matrix resin chemistry. For openmolding and complex curvatures, a soluble binder ispreferred.The soluble binder chemistry wets out thefastest and can also be used in dry winding processeswhere wet strength is not required.The Low Solubilitybinder systems are chosen when wet strength is required,or in cases where high tensile strength is preferred. Epoxyresins are not styrene based and do not quickly dissolvethe soluble binder, so an insoluble binder is typically used.

Wet Process Advantex® vs. Dry Process "C-Veil"OC C-Veils are a standard for the corrosion and openmolding industries. The familiarity in handling thesecombined with a fiber architecture that allows easy wet-out, make these preferred products of many molders.Thelong fibers in OC C Veils can give more conformability incomplex parts.Advantex® OC ECR Veils are a newerproduct with advantages in some applications.The WetProcess used to produce these OC ECR Veils makes aproduct with very high small-area weight uniformity.The binders applied can give a high and uniform tensilestrength to the OC ECR Veil for processes such asfilament winding. Both OC Surfacing Veil product typesoffer excellent corrosion resistance.

Owens Corning manufactures a very broad range of OCSurfacing Veil products and has many other binders andveil products to meet special needs. Contact your OwensCorning representative for special product needs.

PACKAGINGOC Surfacing Veils are wound on cardboard tubes of the same length as the veil.The rolls are wrapped inpolyethylene film and packed in cartons (1 roll per carton),which are then packed on pallets (12 cartons per pallet).
