Water Distribution
Corzan CPVC has a 45 year legacy of successful use in demanding high temperature, high pressure industrial applications. With a track record like that, it only follows a natural progression that Corzan CPVC would become a viable alternative for chemical waste drainage applications.
Chemical Waste Drain Applications
Health care facilities, hospitals, school and university laboratories, as well as industrial plants often generate waste streams that are not suitable to be discharged into the public sewer systems. These chemical wastes must be sufficiently diluted or neutralized before being discharged into the sanitary sewer system. The chemical waste drain systems must be designed with a material suitable to convey these chemicals and corrosive wastes that they transport. There are many existing materials used for laboratory drain service, including polypropylene (PP), polyvinylidene fluoride (PVDF), borosilicate glass, and high silicon iron. While there is no one material of construction that is suitable for every drainage application, CPVC provides specifying engineers with another alternative with many benefits over conventional materials:
Complete system of pipe, fittings, and solvent cement:
Corzan CPVC chemical waste drainage systems are comprised of a system of schedule 40 pipe, drainage pattern style fittings and a specially formulated solvent cement. Transition fittings are also available to transition to other materials of construction.
24448 Cell Classification:
Corzan CPVC has the highest cell classifi cation of any commercially available CPVC used for chemical waste drain service, excelling in both the izod impact strength and the heat distortion temperature. Corzan CPVC chemical waste drainage systems are recommended for intermittent use up to 220°F.
Chemical Resistance:
Corzan CPVC has a broad range of chemical resistance to a wide range of corrosive environments. Less demanding, non-pressure laboratory drain applications lend CPVC to a much wider breadth of chemicals recommended for use than more aggressive, pressurized industrial environments. Laboratory drain service indicates that the chemicals are present in small quantities, on an occasional basis, followed by water flushing, such as from glassware or equipment cleaning operations. For continuous service, or for drainage of larger quantities of chemicals, the Corzan CPVC chemical resistance industrial process piping guidelines should be followed.
Ease of Installation:
Lightweight, yet durable, Corzan CPVC does not require special cutting tools or equipment to install. In addition, Corzan CPVC chemical waste drainage systems are joined using one-step solvent cement. Joints made are chemically fused, resulting in consistent, reliable connections. The specially formulated one-step solvent cement provides chemical resistance to corrosive environments. Other materials of construction, such as PP and PVDF, rely on either mechanical or fusion joining methods. Fusion joints require the use of complicated and expensive fusion equipment that is often inconsistent due to factors uncontrollable at job sites.
Cost Effective:
Simple, reliable installation, as well as low maintenance costs and dependable long term service life make Corzan CPVC a cost eff ective choice for chemical waste drainage systems.
Fire Performance:
Corzan CPVC inherently exhibits outstanding fi re performance characteristics in terms of limited fl ame propagation and low smoke generation.
