Important Considerations to Safely Store and Handle Corrosive Acids and Bases in Industrial Plants

When specifying vessel and piping materials for handling and storing corrosive acids and bases, many lean on their educational training, personal experience and familiarity with products. If a carbon steel, stainless steel or fiberglass-reinforced plastic (FRP) vessel was specified for a similar situation in the past, the plant or operations manager is likely to choose it again, regardless of the expected service life. Relying on personal experience can be valuable, unless there is definitively a better option available. Considering alternatives and the reliability they have delivered in existing applications can help plants recognize greater performance, a longer service life and lower lifecycle costs. To accurately evaluate materials, key comparison factors must first be considered.

Why CPVC is Used For Power Generation Plants

This post is an excerpt from the free downloadable ebook, CPVC Use in Power Generation Plants. To access the full ebook, click here. Power generation plants of all types—from gas turbine combined cycle to nuclear to combined heat and power—all require the movement of large amounts of water and handle caustics and corrosives. Unfortunately, due to the nature of the chemicals used and levels of heat and pressure involved, there are few pipe, valve, fitting, ducting and tank liner material choices available that can provide long-term reliability. That said, judiciously assessing these material options on a system-by-system basis can directly increase operational efficiency, minimize downtime and improve bottom-line performance.

NACE International Hosts Corrosion Technology Week 2018

Mitigating corrosion is a frequent topic of Corzan® Industrial Systems educational resources, and for good reason. Many industrial applications still use materials that are not compatible with their process out of habit and comfort, leading to corrosion, costly repairs, and system downtime. These results all create significant material, installation and opportunity costs. To mitigate these issues, Corzan Industrial Systems introduces corrosion resistant materials where applicable to increase the safety, efficiency and reliability of industrial plants. With chemical resistance to over 400 chemicals, Corzan CPVC pipes and fittings have been solving compatibility issues for over 60 years. The latest development in that effort is Corzan Industrial Systems’ growing partnership with NACE International.

How Fittings, Valves and Strainers Affect Pressure Drop and Head Loss

In our previous post, we discuss the various formulas used to determine flow rate, flow velocity and pressure loss, as well as the factors that piping material selection plays in optimizing fluid handling. Read the full post, here.   When designing industrial piping systems, engineers want a system that will minimize expenses over the long term. Excessive energy consumption increases costs and hurts the bottom line.  Piping system design attempts to maximize energy usage by minimizing resistance to the fluid flow. The harder pumps have to work to move the fluid through the system, the more energy consumed and money spent. Understanding how pipe fittings, valves and strainers create resistance to fluid flow in industrial piping system helps engineers design more energy-efficient systems.

How To Design an Industrial Piping System for Ideal Flow Rate and Velocity

In industrial plants, we often discuss what is being conveyed in the pipe as a function of system design. How a material performs with respect to corrosion and temperature resistance when interfacing with different fluids is a significant consideration during system design. Nearly equal in importance is how the fluid is moving through the pipe. Flow rate plays a significant role in determining a system’s longevity, as well as its day-to-day energy consumption.  Understanding the efficiency with which a fluid can pass through a piping material is a significant step toward ensuring the long-term reliability and cost savings potential of certain materials.

What Is Solvent Cement and Why Is It Used for CPVC Piping Systems?

This post was originally published in August 2017 and has been updated with additional information and resources, including The Complete Solvent Cement Guide.   Chlorinated polyvinyl chloride (CPVC) pipe and fittings are rapidly growing in popularity in both corrosive and high-temperature applications. One reason is, unlike traditional metallic pipes, CPVC piping systems are inert to most mineral acids, bases and salts found in mineral processing, chemical processing, power generation and wastewater treatment facilities.   CPVC piping systems can be joined using flanging, threading or mechanical joining. But in many cases, the recommended method is solvent cement. Solvent cement is a fast, easy and highly reliable process that produces a joint stronger than either the pipe or fitting alone.

What Is Deionized Water and Which Piping Materials Convey It Effectively?

Demineralized or deionized water is used for many lab reactions, laboratory equipment washing, industrial processing applications and more. This water has been purified of ions, minerals, bacteria and other organics that may have been present. Any of those contaminates can alter chemical reactions, cause scaling and corrosion for piping systems, and create a number of unique problems for specific applications. Once demineralized and deionized, water can still harm piping systems if the wrong material is specified because pure water becomes more reactive. Learn about the use cases, qualities and preferred piping systems of purified water to keep your flow free of contaminates and your piping system running longer.

5 Piping Material Considerations for Desalination System Design

You have likely heard it before—more than 70% of the earth is covered by water. However, in terms of potentially consumable water, freshwater only makes up 2.5% of total global water. And 68.7% of all freshwater is bound up in glaciers and ice caps. Put simply, most of the earth’s natural water cannot be easily consumed to sustain life. And with the global population increasing an estimated 83 million people per year, efficient methods for creating safe drinking water must be increasingly adopted. The greatest opportunity for new freshwater is to utilize easily available seawater and convert it to usable drinking water. Desalination is the process used to remove salt from saline water to create potable water. To create a dependable desalination system that will handle its unique demands, specific considerations must be made for the piping material selection.

How Corzan® Industrial Systems Assures CPVC Quality and Consistency

Contrary to what some may assume, Corzan® Industrial Systems does not produce the final CPVC products used in industrial plants around the globe. Rather, we engineer and manufacture CPVC compound from PVC resin, as the chart depicts below.     The Corzan CPVC compound that is shipped to partner manufacturers in pellet or powder form has been fortified with additives to provide superior strength, UV resistance and improved processability for manufacturers. Our propriety CPVC compound also offers inherent resistance to corrosion, high temperatures and high pressures no matter what final form it takes. Our partner manufacturers transform Corzan CPVC pellets and powder into the piping, fittings, sheet, shapes and other CPVC products end users receive. This process begs the question from potential customers: How does Corzan Industrial Systems ensure each product offers consistent quality regardless of when, where or by whom the product is manufactured?

3 Flammability Tests Used to Assess Cleanroom Plastics

Manufacturer cleanrooms keep small particles from adversely affecting production quality. Semiconductor plants, for example, often use cleanrooms when layering and etching silicone wafers for computer chips. Because many hazardous, highly reactive gases and liquids are used to keep semiconductor processes clean, accidental fires can occur. Even the smallest fire and subsequent smoke can: Contaminate a cleanroom, putting a semiconductor plant out of operation for extended periods of time. Create a fire hazard and require immediate evacuation. A proactive solution—typically required for cleanrooms—is to use fire retardant materials across the cleanroom that are both difficult to ignite and give off little to no smoke. When specifying cleanroom piping, ducting, flooring and more, semiconductor manufacturers should look for materials tested in accordance with FM 4910 standards.
