The question of how to avoid the damaging corrosive effects of harsh process chemicals on metallic piping should be the least of the worries of industrial operations and reliability personnel. When these shortcomings are plaguing your clients’ projects, consider implementing material review protocols that do not limit your options. Through no fault of their own, traditionally trained engineers are not immersed in the world of thermoplastics. Yet the implementation of alternate materials of construction review into your Loss of Containment reduction program can create a safer working environment for employees, and provide a more economical solution to a longstanding issue with corrosion.
“Glue” is a term commonly inappropriately applied to the solvent cement process for thermoplastics. It is true that some types of thermoplastics utilize glues, but not all. Don’t let misconceptions about joining methods be the downfall of your project. CPVC materials manufactured to ASTM standards, such as ASTM 441 and ASTM F439, are designed to be chemically welded through a process known as solvent cement welding. It is not a glue.
Delve deeper into CPVC's capabilities, benefits and performance in the harshest industrial applications.
In virtually every line of the pulp and papermaking process, freshwater, process liquids and liquors flow through pipes, filters and screens, and are stored in tanks. The need for paper products in our society is critical, as we have seen during the pandemic of 2020. How the process efficiently and responsibly creates the products is a complex maze of technology that transforms trees into paper. Caustic and corrosive chemicals – sodium hydroxide, sodium sulfide, sodium sulfate and sodium carbonate – are at the heart of these processes. In the process flows, there are wide swings in pH levels as chemical reactions galore advance toward making the finished product we use every day.
Harrison Machine and Plastic Corporation is one of the nation’s largest custom fabricators and distributors of plastic pipe, duct and fittings for a wide range of industrial applications. Since 1970, the company has specialized in thermoplastic fluid and air handling systems that are used in extremely corrosive environments, customizing solutions to meet any customer need.
In almost all of the world’s industries, two core chemicals are likely at their foundation – sodium hydroxide or potassium hydroxide. Solutions of sodium hydroxide (also known as caustic soda) are commonly used in chemical processing, pulp and paper, water treatment, soaps and detergents, bleach manufacturing, textiles, and petroleum products industry. Solutions of potassium hydroxide (also known as caustic potash) are used in applications such as the production of potassium carbonate, potassium phosphate, liquid fertilizer, and potash soaps and detergents.
When designing a data center, uptime is mission critical in choosing your design criteria. For many companies, the data center – that dedicated location for the operation and monitoring of information technology and computing assets – can be as valuable to operations as any piece of equipment. For some companies, the mission is so critical to maintaining business continuity that other highly expert companies operate the data center for them to ensure that stringent uptime requirements are met.
Membrane technology continues to advance at a lightning pace. A type of separation process, membrane technology, is being utilized in processes as varied as absorption, distillation, fouling, microfiltration, nanofiltration, reverse osmosis, ultrafiltration, and desalination. And as the technology advances, so does the dependence on piping systems to maintain fluid stream purity.
Every day, industrial plant professionals must balance many roles and responsibilities that have a direct bearing on OPEX and CAPEX. If they operate facilities with metallic piping systems, part of the job of necessity involves becoming an expert on corrosion – its causes, mitigation and prevention – and devoting significant resources to it from both categories.
Merriam-Webster defines generic as “anything that is not sold or made under a particular brand name.” But when it comes to materials, what’s in a brand name, and how does a branded material differ from a generic? For instance, in some product categories, a generic version of a material may well be an acceptable choice to accomplish the function at hand.
In power plant operations, process chemicals can degrade and reduce the service life of many metal piping systems, potentially causing expensive unscheduled maintenance, disruptive outages in critical operations, and property-damaging leaks in these systems. All of these issues require responsible operators to establish and implement corrosion control and management programs to assure plant availability. These programs typically amount to an ongoing and significant outlay of financial and other resources.
