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.

As commercial/non-residential buildings that have been vacant for several months due to the COVID-19 pandemic return to use, care needs to be taken to prevent inadvertently exposing employees and the public to another respiratory risk factor: Legionella. Legionella is the bacterium that causes the serious and sometimes fatal respiratory infection Legionnaires’ disease. Generally present in local water sources in benign amounts, Legionella microbes are capable of colonizing in warm non-circulating water systems and becoming disease carriers through widespread inhalation of contaminated mist or vapor by building occupants.

A question commonly asked about CPVC piping is what could cause a failure once it is in service. It is not necessary to have a materials science degree to gain an understanding of the factors involved. Essentially, certain conditions must be present for a failure to be set into motion. In this post we will look at what these conditions are and how they may interact with each other.

One of PHCPPros’ key plumbing trends for 2019 is tied to a strong growth area in the construction market – hotel rooms. That trend, prefabrication of building modules, is proving to be beneficial to the plumbing trades, where labor shortages have made jobsite-built projects more unpredictable and costly. And the latest data on rising construction costs, up 4.48% from the same time last year, points to worker shortages as a main factor in that increase.

CPVC pipe and fittings are the material of choice for commercial and institutional plumbing and HVAC applications around the world thanks to their reliability and efficiency. But not all CPVC piping systems are equal. Differences in a CPVC compound’s manufacturing, material science and chemical processing mean that the resulting piping and fitting products may or may not be compatible with all ancillary construction products such as thread sealers, gasket and gasket lubricants, firestop products and cleaners.

The benefits of getting more for your money while keeping a piping project on track should be obvious to any plumbing and mechanical contractor. This is especially true as skilled labor shortages are plaguing the industry. Containing labor costs is more important than ever, so it should be as much a factor as any other in comparing piping materials. That’s why having Corzan® Piping Systems in your construction arsenal is a win-win situation.

The simplicity of working with Corzan® CPVC is renowned by installers of plumbing and HVAC piping systems. Once trained in proper techniques, they come to find that most projects can be completed with only a few handheld tools. So when the need arises to integrate CPVC pipe into existing systems of copper, stainless steel, carbon steel or galvanized steel, the same installation basics make the job cost-effective and straightforward.
Share
The demanding applications for Corzan® CPVC pipe require specific performance characteristics from the pipe once placed in a plumbing or HVAC system. But before pipe goes into service, it must be stored, handled and installed without breaking, and it must possess what is known as impact strength or impact resistance.
Share
In the building community, one of the greatest commodities a specifier possesses is confidence that materials will perform as expected. For HVAC applications, a material must be rated for the operating temperature and pressure of the hydronic system to ensure that it can withstand the internal stresses placed on it by the fluid being conveyed over time and at various temperatures. For thermoplastic CPVC, the International Mechanical Code and Uniform Mechanical Code dictate conformance requirements.
Share
One of the most misunderstood aspects of CPVC pipe is how its pressure rating is calculated and what that rating really communicates to the end user. A common assumption is that the pressure rating is determined by increasing the pressure in a pipe until it bursts. The reality is that CPVC intended for use in pressure piping systems must empirically prove its pressure bearing capability in a surprisingly rigorous data collection and analysis process.

When choosing a piping material, it is important to look for a partner that will be with you beyond the initial sale. You can expect help during the product evaluation and specification stage, but can the manufacturer be counted on to provide expert, timely support throughout installation and over the life of the piping system?
Share
Choosing a building material always carries with it the question of whether to take a “lowest-cost” perspective or to broaden one’s sights by taking the long view. The latter depends greatly on consideration of a total cost of ownership (TCO) analysis that may not be readily available.

Noise reduction is an ongoing challenge in buildings where there are multiple occupants, such as hotels, college dormitories, hospitals and apartments. The noise associated with water flow and water hammer (a pressure surge or wave caused when flowing water is forced to stop or change direction suddenly) can disturb or even wake neighbor occupants during a late-night trip to the bathroom or shower.

Long-term reliability and performance in piping systems are paramount considerations in materials selection, which is why engineers, building owners and facility managers have relied on Corzan CPVC for decades. Also in the mix are the contractors who appreciate this fact: Corzan is so versatile it can be installed using either chemical (solvent welding) or mechanical joining methods. Lubrizol engineered the CPVC compound nearly 60 years ago, and we have not stopped honing and evolving its capabilities.

Many factors contribute to the design and specification of a piping system, from size to pressure to layout. It’s just as critical to think about what’s inside the pipes—the quality of the water and the disinfection treatments that will be used on that water over the life of the system. The additives used for primary and secondary disinfection can often have an impact on the integrity of the pipe.

The lower thermal conductivity of CPVC and other plastic piping materials compared to steel and copper often leads specifiers to wonder whether the material alone is sufficiently insulating for pipe in commercial plumbing and hydronic heating applications. Corzan CPVC’s thermal conductivity is 1/300th that of steel, so this is a reasonable question, especially given pipe insulation’s materials and labor cost. The reality is that it depends on the application.

In all areas of a building project, specifiers, engineers, and contractors need to pay attention to compatibility — how will one material react to another. For example, new types of treated wood containing copper will cause some types of metal fasteners to corrode. Some siding materials can’t be installed against concrete because of moisture absorption. And the list continues.
