Bio-based adipic acid

Adipic acid is a dicarboxylic acid that is widely applied to the production of nylon, polyurethanes, plasticizers and other polymers. Its main use is as one of the raw materials for the manufacture of the polyamide nylon 6,6. In 2012,…

Precise, fast response when controlling large valves

Larger valves (200 mm and above, with flowrates in excess of 200 m3/h) tend to be fitted with pneumatic actuators. However, the air-output capacity required to achieve fast positioning in larger actuators is simply too high for normal positioners and…

This drum vacuum is equipped with double-filter protection

This 110-gallon heavy-duty industrial vacuum (photo) is designed to move material with little wear to the equipment. Engineered to filter contaminants to high-efficiency particulate air (HEPA) requirements, the vacuum is fitted with two filters: a pre-filter to stop larger particles…

Modular piping system now has adapter flanges, too

This company has simplified transitions to its modular pipework system by introducing adapter flanges, which are available in square or round form. The new adapters are welded onto the machine outlet or inlet ports. Matching counter flanges from the company’s…
