�.- 'N/ <br /> File MH19409 Vol. 1 Sec. 1 Page 2 Issued: 1996-05-29 <br /> and Report Revised: 2004-04-09 <br /> CONSTRUCTION DETAILS: <br /> The general configurations and dimensions of the tank sumps are shown in <br /> Table I and in ILLS. 2, 3 and 4. ��-`` s I <br /> The sumps are manufactured of a single wall construction at ��C�V �� <br /> a thickness of 200 mils. They are manufactured in a fabrication <br /> process using glass-fiber reinforcing in combination with an <br /> ispotahlic polyester resin. In various states of the NOV 18 2015 <br /> manufacturing process, the glass fiber reinforcement is applied <br /> in the form of filament winding roving, chopped strand-wooing *roving or <br /> molded. ENVIRONMENTAL <br /> HPAITu nCOAD* ACk- <br /> Double Wall Sumps - The inner sump wall is fabricated identically to the <br /> single wall models. The interstitial material is applied over the single mall <br /> sump and the outer wall is applied over the interstitial material to a minimum <br /> thickness of 200 mils (0.20 in.) . An interstitial access fitting is installed <br /> to allow for testing and/or monitoring in the field. Refer to Ill. 9 for <br /> fabrication process details. <br /> COMPONENT ELEMENTS <br /> The following lists identifies the materials that are used in the <br /> manufacturing process. <br /> A. Isoptahlic Polyester Resins <br /> 1. Reichhold No. 33-407, may also be designated as Reichhold <br /> No. 98-493. <br /> S. Catalyst <br /> 1. Methyl Ethyl Ketone Peroxide in dimethyl phthalate - Technical <br /> Grade. Identified by product name on container. <br /> C. Class Fiber Chopping Roving <br /> 1. Owens Corning Fiberglass, No. 357. <br /> D. Interstitial Material - Parabeam 30 glass fabric Type 87136. <br /> Riser Reducers - The riser reducers come centered, offset and waterproof <br /> bolt down type lids which incorporate a UL Recognized gasket evaluated for use <br /> with gasoline and gasoline/alcohol blends. The risers are contact molded and <br /> are manufactured (of a) Reichhold 33-407 at a thickness of 200 mils. The <br /> risers can range from height of rise of 5 to 12 in. , 29-7/8 to 34 in. OD of <br /> Opening, and 30-1/2 to 34 in. OD of lid. <br /> LMD/WD:lkc <br /> NKDLS <br />
