If someone in the metal fabrication industry described a tube fabrication machine equipped with a sophisticated electronic control package, an onboard diagnostic system, the latest sensor technology, automatic loading and unloading, a combination of hardware and software that allows it to change from one job to the next quickly, and remote access capability so the manufacturer could do some diagnostics and troubleshooting without visiting your facility, what would you think? You’d probably guess that the machine was one of the latest laser cutting machines or a sophisticated, mandrel-capable, multistack, left- and right-hand bending machine, wouldn’t you? These would be two possibilities, but they wouldn’t be the only possibilities. Believe it or not, this description fits some traditional metalworking machines, those that do the bulk of the work in the fabrication industry. These are hydraulically driven machines built with custom-made tooling. These are modern versions of conventional machines. Machines that rely on tried-and-true hard tooling, updated with essentially everything the modern world has to offer. While state-of-the-art lasers and CNC benders have taken tube fabri...

Pressure and Vacuum Sealed Feed-through Assemblies for Sensors, Probes, Electrodes and Wires

Sealed feed-through’s, sometimes called sealing glands, are used to seal elements under the most arduous conditions and have many applications in a wide variety of industries: The main principle behind the design and application for Sealed Feed-through’s is that they inhibit the leakage of gases or other media and restrain the elements from moving in the assembly because of differential pressure. In some assemblies, elements are also electrically isolated from the feed-through body and from each other. Spectite feed-throughs are made from stainless steel and are designed for mounting on to a process vessel or enclosure. Versions can be specified to seal on both single and multiple elements of different types and sizes. Spectite feed-through bodies, followers, seats and series EF SS electrodes are manufactured in an Austenitic stainless steel UNS S31603, commonly designated 316L. Equivalent grades are: (UK) BS 316 S11; (Germany) W.-Nr. 1.4404, DIN CrNiMo 17.13.2; (France) AFNOR Z2 CND 17.12; (Italy) UNI X2 CrNiMo 17.12; (Sweden) SS2353; (USA) AISI 316L; (Japan) JIS SUS 316L. The typical chemical composition for this steel is 0.03%C, 16.0-18.0%Cr, 10-14%Ni, 2.0-3.0%Mo, 0.10%...
