Proco Series 260R Wide Arch Expansion Joints

The Proco Series 260R Wide Arch Expansion Joints are specifically designed for use with plastic or FRP piping systems. A replacement for the standard spool-type expansion joints, the Proco Styles 261R & 262R have exceptionally low spring rates. With low forces to compress, extend or laterally offset, the Proco Series 260R expansion joints can be used on plastic or FRP pipe, pumps, valves or tanks without fear of the expansion joint being stronger than the pipe, pump, valve or tank flanges. In addition, the Proco 260R Series are designed for tough demanding corrosive chemical applications. Visit www.procoproducts.com for more information.

Avantium begins construction of bio-based MEG demonstration plant
Avantium N.V. (Amsterdam, the Netherlands; www.avantium.com) has started construction of a new demonstration plant that will help advance the production of bio-based mono-ethylene glycol (MEG) made directly from renewable sugars. As MEG is a component for making everyday consumer goods, such as PET and PEF plastics and polyester textiles, the development of an environmentally friendly plant-based alternative has strong potential. »
