Random orbital sanders made for general sanding, ultrafine sanding
Extreme series of
in 5- and 6-in. diameters, the tool
is available in nonvacuum and central vacuum models. A
3/16-in.-dia. orbit is offered for general sanding applications. A
3/32-in.-dia. orbit is available for ultrafine sanding.
The sander features an ergonomic design with a tactile soft
grip overmold for a comfortable feel. The 12,000-RPM motor
features an improved rotor design for enhanced power, says
the company. The motor’s V seal protects bearings from contaminants while maintaining lubrication and reducing bearing temperature.
Tube welding controller
integrates GTAW power source
with weld head
model 517 tube
welding controller for orbital tube welding with the EZ
lb. controller integrates the operation
of a standard, commercial GTAW power
source with the weld head.
It has a symbol-based color touchscreen user interface. The user selects
the weld head model, tube size, and
wall thickness and presses the Start
Weld switch on the head. Amperage can
be adjusted by a percentage override to
accommodate tube lot variation.
The standard power source can be
disconnected and used for manual
welding when required.
Stainless steel withstands
temperatures to 1,562 degrees F
Ugitech has added UGI® 4550 to its line
of austenitic, heat-resistant stainless
steel grades. The material is suitable for
such applications as steam lines, superheater tubes, and exhaust systems in
reciprocating engines and gas turbines.
The addition of niobium allows the finished steel grades to withstand temperatures from 797 to 1,562 degrees F.
The material inhibits the formation
of chromium carbide precipitates at
the grain boundaries and thus stops intergranular corrosion. It is suitable for
parts that cannot be treated after welding, such as expansion joints and equipment for chemical processing at high
temperatures. It can be formed at room
temperature and resists hot cracking after welding.
The material resists temperature-de-pendent deformation and atmospheric
corrosion and oxidation at high temperatures.
