New ASTM Standard Expected to Boost PP Piping Systems
Borealis’ PP random copolymer showing up in the first North American plumbing and industrial PP piping projects.
From small plumbing installations to large industrial pipe systems, an innovative PP random copolymer with improved temperature resistance from Austria’s Borealis Group (U.S. office in Port Murray, N.J.) is expected to get a lot of play in North America, thanks to a new ASTM standard.
Pressure-rated PP piping systems have long been standardized in other parts of the world, and have built up a solid track record over the past 30 years. Borealis has used its ‘Value Creation through Innovation’ strategy to develop and pioneer new PP-RCT solutions for exceedingly demanding pipe applications and chlorine-resistant crosslinked polyethylene (PEX) specifically for North American market requirements.
Compared to conventional materials like steel and copper, Borealis’ Niron PP-RCT reportedly offers significant advantages. The new ASTM F2389-17a standard, published in January 2017, makes it easier for North American engineers and builders to select thermoplastic piping systems as replacement solutions for traditional materials. Advantages of thermoplastic piping systems like PP-RCT include: Thermal fusion joining, leak-tight pipe fusion; high corrosion resistance; easy installation and minimal maintenance; long lifetime with improved environmental impact; and, downgauging potential and higher hydraulic capacity than traditional PP-R. Two recent ventures exemplify the broad range of application of PP-RCT:
•Borealis and systems supplier ISCO Industries, Huntsville, Ala., made PP-RCT history with the largest PP-RCT project to date in the U.S. for chilled water and condenser lines inside a newly-built mechanical room. Originally designed to use steel pipes, ISCO reconfigured the plan for the new chiller plant at South Dakota State University to use large-diameter PP-RCT pipes instead, including the first-ever 24-in. PP-RCT pipe.
•Borealis worked with Houston-based Nupi Americas in a project in Illinois to install PP-RCT in an existing elderly-care facility. Niron PP-RCT was used for hydronic installation to re-pipe and ageing system, and for a replacement cooling tower and other equipment.
Expect to see at least twelve startup ventures with exciting new technologies at the 'NPE2015 Startup Garage' exhibitions.
The K 2013 show will present a broad range of engineered plastics materials, including thermoplastic composites, as well as additives. Automotive and electronic applications will be the main targets, as well as medical, packaging, lighting, and construction.
Reversal of some factors driving prices up could change the trajectory in the second or third quarter.
