Fiberglass Tank Pipe Institute Presentation DoubleWall Tank Sump

Fiberglass Tank & Pipe Institute Presentation Double-Wall Tank Sump Session 2017 ASTSWMO May Meeting (May 23 -25, 2017)

Round DW Collars � 42” and 48” round collars � Accepts round base of sumps for rotation and precise alignment www. fiberglasstankandpipe. com

Polygon Sump Base � Bottom of polygon sump base transitions to round � Allows for precise adjustment of base so flat panels align with entry fittings and pipe runs www. fiberglasstankandpipe. com

8 -Sided Polygon Sump Bases � Both the 42” and 48” diameter sumps are 8 -sided � Allows for proper alignment of pipe and entry fitting for 90 and 45 degree couplings www. fiberglasstankandpipe. com

Drain/Test Fitting � Threaded fitting and plug � Designed for annual testing and demonstrating communication between tank collar and sump www. fiberglasstankandpipe. com

2 -Piece Design � Bottom section of polygon base is 2’ high � Avoids confined space entry � Makes installing pipe penetrations easier � Permits immediate pre-testing of entry penetrations www. fiberglasstankandpipe. com

Joint Options Adhesive Channels � Sumps are Layup Joint �connected Sumps arethrough factory installed connected through adhesive channels field installed layup withsupplied kit adhesive kit www. fiberglasstankandpipe. com

Watertight Lid �Manufactured out of fiberglass �No mechanical fasteners �Optional inspection port �Watertight gasket design www. fiberglasstankandpipe. com

Reservoir �Integral fiberglass reservoir that cannot be easily damaged during routine maintenance �PVC threaded opening �Convenient access to sensor www. fiberglasstankandpipe. com

Palletized Sumps � Sumps may be palletized for transportation and jobsite storage � Prevents damage in transit or on-site www. fiberglasstankandpipe. com

ASSEMBLED TANK SUMPS www. fiberglasstankandpipe. com

Assembled Tank Sumps �All piping and electrical penetrations (supplied by others) must seal the tank sump annular space �Do not connect the tank sump annular space to any other annular space www. fiberglasstankandpipe. com

POST ASSEMBLY TEST www. fiberglasstankandpipe. com

Post Assembly Test Prior to backfilling: �The annular space may be pressure tested to a maximum of 3 psig during the installation �After pressurizing, apply a soap and water solution to the entire surface area on the inside and outside of the tank sump �Carefully inspect for leaks as indicated by continuous formation of bubbles �Maintain test pressure and continue inspection for 30 minutes. Then release pressure www. fiberglasstankandpipe. com

ANNULAR SPACE MONITORING www. fiberglasstankandpipe. com

Annular Space Monitoring Hydrostatically Monitored Annular Space �Monitoring solutions available �Brine – Calcium Chloride Solution �Propylene Glycol Solution Vacuum Monitored Annular Space �Vacuum monitoring may be used utilizing the factory installed fitting �Maximum continuous vacuum level shall not exceed 5 psig (10. 2”Hg) www. fiberglasstankandpipe. com

Annular Space Monitoring �Fill the tank sump with the required number of gallons of monitoring fluid www. fiberglasstankandpipe. com
