New Model Specification Announced for Polypropylene Piping

IRVING, TX — The Plastics Pipe Institute, Inc. (PPI) has launched a new Model Specification file for deciding on, specifying, and placing in polypropylene (PP) plastic piping in plumbing and mechanical projects. PPI MS-8 Model Specification for Polypropylene (PP-R & PP-RCT) Strain Pipe Programs for Plumbing & Mechanical Purposes applies to scorching- and chilly-water plumbing distribution, chilled water, cooling/condenser water, manufacture-up water, and hydronic heating and cooling distribution piping programs, including district vitality. It became as soon as prepared as a carrier to the alternate by the affiliation’s Building & Building Division (BCD).

In line with PPI, with excessive temperature and power capabilities, polypropylene power pipes are ethical for stressful piping purposes in commercial constructions, info centers, factories, colleges, health care companies, lodges, and further.

Better than 6,000 feet of PP-RCT piping became as soon as put in on the US Air Power’s Joint Substandard San Antonio-Lackland, Texas for warmth and chilly potable water, non-potable HVAC heating and chilled water, plus condenser water. The pipe became as soon as selected for its increased power capabilities at increased temperatures than primitive PP offers.

PPI MS-8 is supposed to be a info to boost engineers, designers, and specifiers of plumbing and mechanical piping programs with language that can also be copied and pasted into invent documents to manufacture certain that the latest requirements for polypropylene piping offers are normal. It offers suggested language for PP pipes, fittings, and valves; provide, handling, and storage; becoming a member of, installation, and safety; insulation and safety; power testing and commissioning of polypropylene power pipe programs.

“Polypropylene is a versatile power piping discipline materials normal in a colossal different of purposes,” acknowledged Lance MacNevinP. Eng., director of engineering for PPI’s Building & Building Division. “It is straight away available in two styles: PP-R, or polypropylene random copolymer, and PP-RCT, polypropylene random copolymer with modified crystallinity and temperature resistance. Every form is effectively matched with the other. PP power piping programs were first normal for plumbing and hydronic heating within the Eighties in Europe and supplied to North The US greater than twenty years within the past.

“One amongst the benefits of a PP machine is that both pipes and fittings are comprised of the same discipline materials and would possibly possibly presumably presumably neutral also be joined the usage of first payment warmth fusion, which offers a leak-free machine with out the usage of commence flame,” he persevered. “Product standards and specs for PP piping fetch developed in fresh years, so a specifier who makes use of out of date language would possibly possibly presumably also neutral inadvertently specify a product that now now no longer exists available within the market, or one that is solely much less capable than the fresh screech-of-the-art work.”

The staff of experts from PPI member firms that developed MS-8 consulted with the latest mannequin standards and codes from ASTM, CSA, NSF, IAPMO, and ICC when increasing the advise material. The brand new mannequin spec contains particular requirements for potable water and chilled water purposes, as effectively as flame and smoke rankings, thermal and vapor barriers, and further.
