Here’s what it takes to make an exhaust duct joint on FRP Duct
Joints on FRP duct are traditionally accomplished by means of a labor intense "butt and wrap" procedure. Duct ends are ground smooth, exposed ends are sealed with catalyzed resin, and the duct or fitting is "buttered-up" and overlaid with several layers of resin and reinforcing fiberglass.
Adhesive curing at an ambient temperature of 70°F would take at least 24 hours to complete, so electric heating blankets are often required to accelerate the time to cure each joint.

10 Benefits of Fluoropolymer Coating on Stainless Steel Duct
Corrosive fume exhaust systems and vent duct products should be just that... corrosion resistant. For decades, wastewater treatment facility owners (and engineers) have faced a major pain point with plastic and FRP systems that degrade and need regular repair or replacement.
Compounding this pain is the fact that many plastic and FRP exhaust duct products are highly combustible. In the event of a fire, or gaseous ignition, such systems will likely be rendered useless if not completely destroyed. In short, wastewater facilities with these types of systems face the pain of higher fire insurance premiums; and those that self-insure face catastrophic losses.

Fluoropolymer Coating - Q&A
What is a fluoropolymer? A fluoropolymer is a fluorocarbon-based substance that contains atoms of fluorine. It is characterized by a high resistance to solvents, acids, and bases. Fluoropolymers were discovered by happen-stance in 1938 by Dr. Roy J. Plunkett as he was working on freon (for the DuPont corporation) and accidentally polymerized tetrafluoroethylene.
The result was PTFE (polytetrafluoroethylene), more commonly known as Teflon. This material was found to have the lowest coefficient of friction of any known solid and was inert to virtually all chemicals known. Its corrosion resistivity (in almost all applications) exceeds that of glass (borosilicate and enameled glass-steel) and exotic alloys such as Hastelloy, Niobium, Tantalum and Titanium.

Urban Growth Projections and wastewater Treatment Implications
Over the next 6 years, the global market for wastewater treatment equipment and chemical products is expected to grow by more than 138 billion dollars (1). This enormous increase in spending will be driven by shrinking clean water supplies, increasing demand from growing populations, and the growth of industrial applications beyond current water treatment capacities.
The United Nations is reporting that by 2025, fresh water usage will increase by 50% in developing countries and by 18% in already developed countries. They also estimate that 1.8 billion people will live in areas where water sources are limited and roughly two thirds of the earth’s population will live in potentially limited areas for clean water (1).
