38. Thermoplastic Double Wall Piping Systems—What You Need to Know 7/5/2013

    Double wall piping systems are essentially a piping system within a piping system. The inner pipe is referred to as the “primary” pipe, while the outer pipe is referred to as the “secondary” or “containment” pipe. The goal of double wall piping is to create a failsafe system where the secondary containment piping would contain any leaked fluid if a failure occurred in the primary piping. Available in a variety of materials, double wall piping systems are ideal for many applications. By Steven Dolejsi, Applications Engineer, IPEX USA, LLC

39. Thermoplastic Valves Come With Benefits And Considerations 7/3/2013

    With advantages like corrosion and chemical resistance, ease of installation, low maintenance, durability, and resistance to scale and bio film build-up, thermoplastic pipe and fittings have become a common choice for water treatment systems. However, there is still a misconception in the industry that plastic pipe is only used for the water distribution applications within a treatment facility.

40. WEFTEC: 10 Technologies That Could Change The Industry 10/22/2012

    So many products, so little time. That’s the impression I came away with after canvassing WEFTEC for three days in New Orleans earlier this month. There were nearly 1,000 exhibitors on hand, enough to make anyone’s head spin. It’s a good kind of dizzy, however, when you are overwhelmed by new technology and smart ideas at every turn. From the many technologies I surveyed, here are the 10 most noteworthy.
