Bolt Load and Elongation Measuring Device
Boltight has developed a fast and accurate device for measuring bolt
load and bolt elongation that uses the latest ultrasonic technology.
Called the Boltight Echometer, the device is used for monitoring
critical bolting applications either during the installation of a new
plant or while carrying out routine maintenance. The Echometer
works by measuring the time of flight of a sound wave as it
travels through a bolt. When the wave hits the end of the bolt,
it reflects back into the transducer. This enables a measurement
to be taken. Depending on how the device is set up, a reading is
displayed in units of load, stress, or strain on a handheld screen
the size of a mobile phone. (www.echobolt.com)
Updated Tube Expansion System
An updated HydroSwage Tube Expansion System featuring new ease-of-use and
data collection features is being offered by Haskel International. The compact
Mark V system provides high accuracy, speed, and repeatability by expanding
heat exchanger tubes into tube sheets through the direct application of high
internal hydraulic pressure. It is designed for use in fabricating heat exchangers
for steam generation, condensation, and evaporation.
Designed to provide one-step high-pressure expansion regardless of the tube
sheet thickness, HydroSwage expanding mandrels feature a patented segmented
seal support system that holds high pressures with minimal seal extrusion.
Capable of expansion pressures to 50,000 psi, the system accepts 100 to 240
VAC single-phase and requires air inlet pressure between 70 and 150 psi with a
minimum of 70 scfm. Expansion pressures are applied uniformly, tube after tube,
yielding consistent joints throughout the tube sheet. The method has been
applied successfully to expand tubes into tube sheets as thin as 19 millimeters
and as thick as 84 centimeters. The
system includes touchscreen
electronic
controls for setup of
all process functions.
Expansion history
is stored and can be
downloaded to an
Excel spreadsheet
through a USB port.

Total Biogas Package
German company MWM introduced the
new MWM container, which it says
is a highly efficient and economic
distributed generation system
designed for natural gas and biogas
applications. The package, which
includes a biogas genset, a standard
container, and biogas processing, are
aligned with special requirements
of biogas operation. For example,
it uses specially designed exhaust
turbochargers and controlled gas
systems. Efficiency is substantially
improved by optimized chamber spark
plugs and special pistons. Moreover,
the cooling water and exhaust gas heat
exchanger are integrated in the heating
circuit. The container includes the
genset, peripherals, and switchgear.
