Pipes make the right connection; proper contact with fittings and valves can boost product flow and reduce leakage

Article Abstract:

Flexicraft Industries General Manager Paul Berg said certain allowances must be given so that connecting devices between sections of pipelines, that convey hot liquids, can tolerate pressure and thermal expansion. Berg illustrates the challenge that comes with ensuring that there is correct contact with fittings, valves and other components in a piping system. The right connection eases product flow with a minimum of leakage and maintenance. In 1997, Flexicraft launched a U-shaped expansion joint, that is made of flexible metal, as a third option to the straight-line bellows expansion joints or hard-pipe U-loops.

Getting a better handle on bulk solids flow

Article Abstract:

Makers of conveyors, feeders and storage silos are designing systems that can accommodate specific material properties of bulk solids. This is in response to the new stadn for Jenike shear testing, D612897, issued by the American Society for Testing and Materials. The test procedure calls for the preparation and compaction of a bulk material in the Jenike fixtire. The force necessary to shear the compacted specimen is measured, and the data is used to design silon, bins, hoppers, conveyors, mixers and feeders.

Valves widen the field of operation

Article Abstract:

Improvements in valves are allowing companies to double the time between maintenance shutdowns. One of the advances in valves is the inclusion of microchips on valve controllers, to conduct diagnostics, data collection and manage communications. Customers are also demanding capabilities that put process control in the field devices. These include an intelligent digital positioner and process controller for pneumatically actuated valves.
