Polypropylene piping system
Aquatherm’s Greenpipe polypropylene-random (PP-R) piping system
Aquatherm’s Greenpipe polypropylene-random (PP-R) piping system is available in sizes up to 18 in. in diameter and is ideal for water mains and high-rise buildings. The new 18-in. Greenpipe features a standard dimension ratio 11 (SDR 11) wall thickness, which can deliver 4,000 to 6,000 gpm and provides a balance of strength and flow rate. Greenpipe can be directly buried in soil, sand, and other materials. Aquatherm’s natural R-value of 1—or more depending on pipe size and SDR—also delivers potential savings in terms of insulation and energy loss.

Annual Salary Survey
After almost a decade of uncertainty, the confidence of plant floor managers is soaring. Even with a number of challenges and while implementing new technologies, there is a renewed sense of optimism among plant managers about their business and their future.
The respondents to the 2014 Plant Engineering Salary Survey come from throughout the U.S. and serve a variety of industries, but they are uniform in their optimism about manufacturing. This year’s survey found 79% consider manufacturing a secure career. That’s up from 75% in 2013 and significantly higher than the 63% figure when Plant Engineering first started asking that question a decade ago.
