Understanding the capabilities of engineered piping materials not typically covered in college curricula can be a daunting task for plumbing engineers. For those interested in considering alternative materials to copper, such as CPVC, that knowledge is best acquired by doing one’s own research into performance properties and product testing and reaching out to manufacturers’ specialists to further unlock insights.
A Heated Situation Air conditioning and Arizona go hand in hand, except when an owner neglects preventive maintenance for decades. The new owner of a 240-unit Phoenix apartment complex plagued by unreliable A/C due to persistent leaks in the HVAC system had a big problem on his hands.
Delve deeper into CPVC's capabilities, benefits and performance in HVAC applications.
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.
Capital Health Plan (CHP), a nonprofit managed care organization, is a nationally-recognized provider of comprehensive preventive, primary and specialty healthcare services for its members in the seven-county Greater Tallahassee, Florida, region. Plumbing and mechanical contractor Scott-Burnett, Inc. won the bid to provide Corzan® CPVC piping for the plumbing in CHP’s new Metropolitan Health Center project, a three-story building of 72,000 square feet comprising physician offices, urgent care, imaging, lab services, wound care and a center for complex care.
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.
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.
In multi-story construction, designers not only need to consider expansion and contraction for horizontally run pipe, but also the design and installation of the vertical piping. One school of thought when installing Corzan® CPVC for hot water riser systems is to use expansion loops similar to horizontal installations to account for thermal expansion.
Thermoplastic Corzan® CPVC pipe and fittings are designed to meet the temperature and pressure requirements of HVAC applications and withstand the internal stresses that result from conveying fluids over time at various operating temperatures, up to 180°F, in these complex projects.
The transformation of San Diego’s North Embarcadero waterfront into the Portside Pier development was a joint project by the Port of San Diego and its restaurant partner Brigantine. Pacific Building Group (San Diego, California) was selected as the general contractor to oversee construction of the new concrete piles and a concrete pier with a two-story framed structure atop it, housing four dining establishments. For the hot and cold domestic water supply to these restaurants, the plumbing specification called for piping to be below the pier, and for this piping below the pier to be corrosion-resistant CPVC ranging from 3" down to ½".
Inquiring minds need to know: How did Corzan® CPVC transition from use in aggressive industrial pipe applications to becoming a trusted material for decades of reliable service in commercial plumbing and hydronic HVAC applications?
