Processes within power generation plants must be reliable and efficient – especially since facilities cannot economically store electric power and must be online and produce power to meet demand. The need for high levels of reliability coupled with the ability to withstand the very harsh conditions present in most power generation plants is inciting designers to specify non-metallic pipe materials such as Corzan CPVC® to achieve long-term, cost-effective performance.
The heat is on for piping systems installed in most industrial environments – in the form of high temperatures, elevated pressure, thermal cycles, excess heat generated by the sun and the heat of exotherms resulting from process upsets and operator error. Fire is also a hazard in many industrial applications, and especially within the chemical processing industry, and requires engineered systems with properties such as ignition resistance, burning resistance and flame spread resistance to help keep workers safe and limit property damage in the event of a fire.
Delve deeper into CPVC's capabilities, benefits and performance in the harshest industrial applications.
Versatile Corzan CPVC® is specifically engineered to meet performance requirements in the harshest environments across a wide range of industries. The material is inherently inert to most mineral acids, bases, salts and aliphatic hydrocarbons and resists corrosion, a common problem that plagues many industries and results in costly downtime and repairs. CPVC also offers superior mechanical properties to ensure a long service life with minimal pipe maintenance.
Metal may have been the material of choice for industrial piping systems during decades past. But the cost to install and maintain a metal system may overshadow performance advantages such as metal’s strength and its ability to withstand high levels of heat and elevated temperatures.
Industrial applications are demanding environments for any piping system, placing stress on materials and joints. Piping materials and their connections must be able to withstand challenges such as constant vibration and water hammer, extreme temperatures, changing pressures and exposure to highly corrosive chemicals.
Corzan® chlorinated polyvinyl chloride (CPVC) offers the peace of mind that comes with a piping system that provides superior resistance to corrosive chemicals at high temperatures and pressures. Corzan CPVC can be used for pressurized service up to 200°F and offers a higher pressure rating over most of its useful temperature range than most of the other thermoplastic materials used for industrial piping. as illustrated in the chart below.
Industries invest millions of dollars each year in technology and equipment to grow their productivity, profits and performance. Yet, a silent hazard in the form of corrosion continues to plague industries around the world, with the global cost of corrosion surpassing $2.5 trillion each year, which is 3.4 percent of the global GDP. Corrosion costs the U.S. production and manufacturing sector $17.6 billion annually.
Power generation plants move large quantities of water, caustics and corrosive chemicals during the power production process. Designing piping systems for these facilities can be a challenge based on the very nature of the chemicals used and the high levels of heat and pressure.
Industrial piping design engineers are naturally cautious people. They like to feel confident that the system they install will operate safely and reliably over the long term.
A surge in pressure within a piping system, known as water or fluid hammer, occurs whenever the linear flow rate of fluid in pipe changes quickly – when pumps start or stop, valves open or close with quick acting actuation devices, or entrapped air moves within the system. The longer the pipe line and the faster the fluid is moving, the greater potential for shock.
