The Impact of Fluctuating Steel Prices on Industrial Systems

When designing and building industrial systems, including pipes, fittings, valves and tanks, steel is one of the most widely utilized materials. Stainless steel and carbon steel are two common forms that have been used for processing applications for decades. But as political and economic uncertainties compound, the price and supply of commodities like steel becomes more volatile. As of August 2018, the price of steel was 44.2% higher than during the same period last year. After five years of mostly consistent price drops for stainless steel, the recent jump is cause for concern for industrial plants.

What To Know About CPVC Classifications and Cell Classes

ASTM F441 is the Standard Specification for CPVC Plastic Pipe, Schedules 40 and 80. Per the standard’s requirements and test methods, CPVC is assessed for “materials, workmanship, dimensions, sustained pressure, burst pressure, flattening and extrusion quality.” Another set of CPVC standards is defined by ASTM D1784. This specification assesses CPVC according to “base resin, impact resistance under notch, tensile strength, modulus of elasticity in tension, deflection temperature under load and flammability.” By specifying CPVC that meets ASTM F441 and ASTM D1784, users should have confidence that their industrial piping systems will perform as expected. Yet, not all approved CPVC is created equal. Within each standard are distinctions that set certain CPVC compound producers and manufacturers apart.

Why Valves Deserve Greater Attention in Industrial Piping Systems

When deliberating between material choices and general industrial piping system design, the primary considerations revolve around pipes and fittings. Specifically, the focus is typically on the pipe and fitting materials’ temperature, pressure and compatibility characteristics. Valve selection is often an afterthought finally considered once those primary decisions are settled. But valve decisions are vast: types include ball valves, gate valves, globe valves, butterfly or wafer valves, check valves, diaphragm valves and more. The number of valves can vary greatly in a system depending on the purpose of the piping system. However, valves are critical to any successful system due to their importance in controlling the flow. Also, because a system is only as strong as its weakest component or joint, valves deserve much greater attention when considering material options.

Why Use CPVC in Wastewater Treatment Plants?

The following is an excerpt from “CPVC Use in Wastewater Treatment Plants.” Download the full ebook to learn more about where CPVC can be installed in wastewater treatment plants, which chemicals CPVC stands up against and how CPVC compares to alternatives in various applications. Wastewater treatment plants are extremely corrosive environments. During the treatment process, large vessels and piping systems convey polluted water and highly corrosive and caustic chemicals. To keep wastewater treatment plants efficient and cost-effective, appropriate material selection is critical. Corrosion to pipes, valves and fittings caused by chemicals and microbes can greatly impact the bottom line at water and wastewater treatment plants. As a result, engineers and procurement officials turn to an economical, reliable material—chlorinated polyvinyl chloride (CPVC).

The Basics of Industrial Piping System Valves

In an industrial system, and in any piping system, valves are used to restrict, stop or control the flow of fluid. More specifically, some industrial valves are used to: Control the cooling rates of water through cooling lines to regulate the temperature. Manage the flow of concentrated acids or bases flowing through a line. Redirect flow from one line to another at a three-way valve. Restrict flow for system balancing. Prevent reverse flow (check valves).  Automatically stop the flow in the event of a system failure. When considering available valves for an industrial system, evaluation depends on both the short term and long term performance of a valve. And depending on the application, one valve may outperform another and provide a superior service life.

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.
