Corzan Piping Systems for Industrial Applications

CORZAN^® CPVC Pipe & Fittings Performance you can count on.

Made from durable chlorinated polyvinyl chloride (CPVC), Corzan Industrial Systems offer superior resistance to corrosive chemicals, high temperatures and harsh application conditions. As a result, pipe and fittings made from Corzan CPVC deliver what the process industry needs most – longer service life, lower maintenance costs and reduced downtime.

No industrial system, metallic or non-metallic, performs better than one made from Corzan^® CPVC pipe and fittings. And now, Corzan Industrial Systems has set new standards for performance in both pipe and fittings. Corzan CPVC pipe meets a new cell classification as defined by ASTM D1784 standards, proving it to have the highest impact resistance and heat distortion temperature (HDT) of any CPVC compound available. What’s more, recent performance testing of fittings made from Corzan CPVC compounds demonstrated a greater resistance to creep at elevated temperatures when compared to those manufactured from generic CPVC compounds.

With its enhanced reliability and proven long-term performance characteristics, Corzan Industrial Systems can tackle even the toughest process environments. Ideal for applications in the metal finishing, pulp and paper, water and waste treatment, chemical processing, semi-conductor and chlor-alkali industries, Corzan CPVC is the system of choice for today’s most discriminating process engineers.

PIPE - In a class by itself.

Corzan Industrial Systems offers the only industrial pipe certified to the highest cell classification of 24448 of any commercially available CPVC as defined by ASTM D1784. Under this classification, Corzan CPVC demonstrates an impact resistance greater than other CPVC pipe and backed by the highest HDT of any CPVC compound on the market.

The ASTM D1784 standard assigns a numerical value (or cell classification) to the test results for each of four physical property tests. This independent testing shows Corzan CPVC has earned a cell classification of 24448, becoming the only CPVC to be rated this high. Standard CPVC compounds have a 23447 cell classification.

Such durability, combined with a proven record of unparalleled corrosion resistance, make Corzan CPVC an ideal solution for applications that require corrosion resistance and high temperature performance.

High-impact Corzan pipe for high-temperature applications is available in sizes from 1/4" to 8" from select manufacturing partners. Contact individual manufacturers for the complete availability of Corzan pipe.*

* Corzan CPVC pipe is available through 16” diameter. Corzan CPVC pipe meeting the 24448 cell class is available through 8” diameter from select manufacturing partners.

FITTINGS - Fit for high-pressure applications.

Industrial pipe and fittings respond differently to internal pressure. Corzan CPVC is the only commercially available CPVC fitting compound that carries a pressure rating as Listed by PPI (Plastics Pipe Institute). This Corzan^® CPVC compound has been pressure rated in accordance with ASTM D-2837 and PPI TR-3 having Hydrostatic Design Bases (HDB) of 4000 psi at 72°F and 1000 psi at 180°F as listed in PPI TR-4.

When compared to generic CPVC materials, fittings made from Corzan CPVC demonstrated improved creep resistance and the ability to better withstand long-term, high-temperature hydrostatic pressure. When compared under the same conditions, fittings molded with Corzan CPVC compound lasted four times longer than those molded with other CPVC compounds when pressure tested at 180°F (82°C) at 551 psi.

One of the key advantages to Corzan CPVC is its excellent resistance to a wide range of corrosive materials. Many chemicals encountered in industrial applications aggressively corrode most metal equipment, resulting in process leaks, flow restrictions, and ultimately, premature failure.

Corzan CPVC is inert to most mineral acids, bases, salts and high-molecular weight aliphatic hydrocarbons and compares favorably to other metallic and non-metallic piping systems in these chemical environments. It also performs well against strong oxidants and halogens.

In addition, to provide both the corrosion resistance and mechanical strength to meet process design requirements, conventional materials are altered to compensate for inherent weakness. For example, steel piping is often lined with non-metals, resins are reinforced with glass, or exotic metal alloys are utilized. These changes can significantly increase the installed cost of a project. Corzan Industrial Systems inherently have both the corrosion resistance and mechanical strength required for many process applications at a total installed cost lower than alternative piping systems.
