Revisiting Chemical Process Applications

Due to their excellent chemical and corrosion resistance properties, industrial thermoplastic piping products, such as PVC and CPVC, continue to gain acceptance in numerous applications previously dominated by metallic piping. In many industrial processes, the use of thermoplastics in lieu of metallic piping, can provide valuable cost savings to the end user by improving the efficiency and life expectancy of piping systems.

Will We See You in Baltimore for the 2011 Plastics Expo? (Here’s a secret. It’s free)
Actually, it’s no secret that IAPD’s 2011 Plastics Expo, Thursday, Sept. 15, is free. It’s also the only place where you can meet with the people who make, distribute, specify and purchase semi-finished plastic stock shapes, fabricated parts, as well as pipe, valves and fittings. This is the only event that can boast such expertise in one place.

Free registration for the 2011 Plastics Expo is opening very soon. Watch www.iapd.org and the next issue of Designing with Plastics for all the details.

High-Performance CPVC Pipe Installed for Corrosive Bleach Plant Application
Pipe and fittings constructed of durable chlorinated polyvinyl chloride boast a number of superior performance characteristics over engineered metallic systems to serve as a reliable alternative for the transport of corrosive chemicals. CPVC piping has demonstrated excellent service in bleach-plant process lines, even when exposed to several corrosive acidic and caustic solutions found in bleach preparation and process operations.

Technical Advisory



CPVC has an upper working temperature limit of 200 degrees (93 degrees Celsius), or approximately 60 degrees (16 degrees Celsius) above that of PVC, which greatly increases the product’s application range and makes it advantageous for many aggressive high temperature processing applications such as plating and chemical processing.

CPVC is used in the manufacture of pipe, fittings, valves, machining shapes, sheet and duct, offering advantages for piping and related applications due to its high glass transition temperature, high strength to weight ratio, pressure bearing capability, corrosion and chemical resistance and low friction loss characteristics.
Although PVC and CPVC are similar in nature, they are not the same. Care should be used when investigating and comparing the chemical resistance, processing, joining and fabrication techniques and applications of PVC and CPVC.

Sustainability of Plastic: Did You Know…



It requires 91 percent less energy to recycle plastic bags than paper bags.

Some plastics can be recycled. Hundreds of quality products made with or packaged in post-consumer recycled plastic now are commercially available. Two soft drink bottles can make a baseball cap, when recycled into polyester fiber. And artificial lumber made of recycled plastic is used in sea walls, fence posts and park benches. Plastic bags and stretch wrap are finding their way into decking material that is unsurpassed for its durability. It does not decay or crack, resists damage from termites and ants and requires no protective sealants.
Plastic packaging, which makes up less than 6 percent (by weight) of discarded products in the municipal waste stream, can be disposed of safely in landfills.
