Manufacturer Total Containment, Inc. (TCI), located in Exton, PA is the manufacturer of the Pipe JacketIm secondary containment components all components are shipped directly to TCI customers from the Exton, PA facility. TC1 manufactures additional products such as the Tank Jacket, a secondary containment system for underground tanks, and the TCI Leak Detection System. Primary Piping The primary piping to be jacketed can be fiberglass, steel, or any other type of primary piping'which has been approved . and/or specified by local regulators. Before final assembly of the Pipe Jacket an air pressure test must be performed on the primary piping to detect any leaks that may exist. Secondary Containment The Pipe Jacket installed over the primary piping provides a double wall piping system which can prevent leaking product from escaping into the environment. The Pipe Jacket performs as an air tight guttering system, providing total containment of the primary piping system from under the dispensers to the submersible pump, including all swing joints ®or flex connectors. Any leak in the primary pipe will flow from the high end of the system towards a collection sump, Wocated at the low end of the system. Pipe Jacket Sealing There are two types of sealing systems available, from TCI,for the Pipe Jacket. They are as follows: Fusion Seat System: All overlap joints in this secondary containment system are sealed by using a polyethylene coated resistant wire which is inserted and clamped into a pipe or fitting overlap joint. The wire is then connected to 24 volts to generate resistant heat sufficient to create a homogeneous bond between the two components. Mechanical Seal System: All overlap joints in this secondary containment system are sealed by using a Compression Seal and stainless steel clamps. By tightening the clamp over the Compression Seal, when sandwiched inside the overlap joint a mechanical seal is achieved between the two components. Pipe Jacket Materials All components used In the Pipe Jacket Secondary Containment System, are made of materials suitable for the application. Each has excellent properties for use in underground applications and compatibility with hazardous liquids. The materials used are listed as follows: High Density Polyethylene (HDPE): This material is used in a variety of .molding processes to produce; straight pipe,flex pipe, fittings, sump/risers, couplings, collars, and fusion welding wire, ribbon and rod. Buna-N (Nitrile) (NBR): This material is used to make the Compression Seals used In the Pipe Jacket: Mechanical Seal System. Stainless Steel (300 Series Plus): This material is used to make all components of the compression band clamps used for both the Fusion and Mechanical Seal System of the Pipe Jacket. Corrosion Protection hen the Pipe Jacket Secondary Containment System is used to containsteel primary piping, it provides an excellent means of corrosion protection because it Isolates the steel piping from the environment that surrounds it. This Isolation reduces the possibility of dl-electric, chemical and microbial corrosion beacuse the steel piping does not come into contact with stray electrical current, chemicals, or sulfate reducing bacteria (SRB's) that are commonly found in most soils.
