Fuseal Squared® Double Containment Corrosive Waste

Fuseal-squared-330x240

Federal, state and local regulations have been created to protect our environment from industrial pollution. Protection of the soil and the groundwater table are of primary concern. The Fuseal Squared® system, with a modular design, is a reliable and cost-effective solution for conveyance of industrial and laboratory waste products. Excellent chemical and physical properties make the system ideal for handling corrosive waste solutions present in laboratory and industrial DWV applications where double containment is required.

Fuseal Squared® in Polypropylene or PVDF combines the advantages of corrosion-resistant and flame retardant drainage piping with the added security of double-containment.

  • UPC 164-2001 – Standard Specification for Dual Containment Piping Systems intended to Convey Acid Waste or other Special Wastes (pending)

1.2 SUBMITTALS

  1. Catalog Data: Contractor shall submit copies of manufacturer’s literature on the Fuseal Squared system. The literature shall contain complete and current installation instructions.

PART 2 - BASIC SYSTEM DATE

2.1 MANUFACTURER

  1. The corrosive drainage waste and vent system shall be Fuseal Squared (1½" x 4" – 8" x 12") as manufactured by GF Piping Systems.

2.2 MATERIALS

The products described in this specification consist of:

  1. Pipe and fittings made of non-flame retardant polypropylene, joined together by electric fusion coils made of conductive-metal wire coated in polypropylene and either molded or independently fit between the fitting and pipe components. Pipe and fittings shall consist of both primary and containment components fabricated by the factory.

  2. Joining Method – The pipe and fittings are joined by use of the electric fusion coils energized by a low voltage power supply. Couplings shall be used as the standard joining connection.

  3. Basic Materials / Compounds - Fittings, pipe, centralizers, and/or other components of the corrosive waste drainage system shall be manufactured in accordance to ASTM D-4101 “Standard Specification for Propylene Plastic Injection and Extrusion Materials” from either Type I, homopolymer polypropylene or Type II, copolymer polypropylene.

2.3 SOURCE QUALITY CONTROL

  1. Pipe Dimensions – Pipe shall be produced to Schedule 40 Iron Pipe Size dimensional standards and meet ASTM F-1412 quality requirements for “Polyolefin Pipe and Fittings for Corrosive waste Drainage Systems.”

  2. Fittings Design – Fittings design shall be based upon ASTM D-3311 “DWV Plastic Fitting Patterns.”

  3. Electric Fusion Coils – Each coil shall consist of a polypropylene jacketed wire, mandrel wound, and heat fused on the outer surface. The coils shall be either molded into a polypropylene collar or shall be independent and loose fitting pending the size used. Both styles shall have a duplex receptacle for connection to the fusion unit.

  4. Pipe Markings – All pipe shall be marked with +GF+ Fuseal, pipe size, Schedule 40, PP110, ASTM F1412, UPC, date stamp, “Made in USA”; and be compatible with the coil fusion method.

  5. Fittings – Primary components shall be molded or fabricated via standard plastic injection molding, butt-fusion or electrofusion. Secondary components shall be molded or fabricated via standard plastic injection molding, butt-fusion, manual hot air welding or electrofusion. Centralizers shall be welded to the primary component of the fitting and/or pipe. Custom fittings shall be allowed per engineering specification as required; however, they shall conform to the requirements of this specification.

  6. Chemical Resistance – Fuseal Squared meets the same chemical resistance values as standard Fuseal polypropylene material. Please consult the chemical resistance chart located in the Fuseal Squared Technical Specification, Section 6.
