Quality specifications have a direct impact on long-term performance. Industrial facility project managers know they must take quality into account when determining the most suitable material for demanding piping systems. If you have the ability to specify high-quality materials without incurring additional costs, it is a win-win for any facility. If using quality specifications is not part of the process, they are putting their facilities at risk for unplanned downtime and other liabilities. But is the cost of quality too high?
It was an old boiler that exploded, devastating three floors and the building’s roof at the Grover Shoe Factory in Brockton, Massachusetts, on March 10, 1905 (ASME.org). The unthinkable tragedy resulted in 58 deaths and 117 injuries. This gave rise to the Board of Boilers Rules, Boiler Code Committee of 1911, and to the eventual publication of the Boiler & Pressure Vessel Code (BPVC) in 1915.
Delve deeper into CPVC's capabilities, benefits and performance in the harshest industrial applications.
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.
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.
The question often arises, can I weld pipe and sheet together? The answer is yes, but the process requires skilled thermoplastic welders who are properly trained and have been tested just as metallic certified welders are tested.
Designers and engineers often specified metal piping for industrial applications in the past based on the material’s familiarity. Today, metal piping is still used in some environments because of misperceptions regarding chlorinated polyvinyl chloride (CPVC) piping.
Minimizing energy costs is one of the main areas of opportunity for plant owners looking to increase their bottom-line. At a macro level, according to the U.S. Energy Information Administration (EIA), the industrial sector uses more energy than any other sector, consuming about 54% of the world’s total delivered energy. Engineers are always looking for ways to optimize system processes to improve energy efficiency to decrease energy expenses. Proper piping material selection is one opportunity to limit energy consumption. Take a look at how CPVC piping compares to metal piping in terms of energy efficiency across a system’s lifecycle, even before the pipe is installed.
Industrial plants are challenging environments for piping systems, which are subject to extreme pressures, temperatures, stress and even impact. No matter what piping material is specified, piping system stresses must be considered and modifications made during system design to prevent issues that could require extensive repair or replacement.
