Tips for buying a second-hand bending machine

September 10, 2012

By: , ,

The second-hand market can be a good source for a used bender, but buyers must be careful. A thorough evaluation of the bender’s capabilities and condition is necessary before making a purchase. Because modern benders are complex and sophisticated, the evaluation is best carried out by the manufacturer, not the buyer. Another option is buying a reconditioned machine from the manufacturer. However, depending on the bending needs, a new bender might be the only viable option.

Taking NDT to the end of tube, pipe

September 10, 2012

NDT systems are limited in how close to the end of a tube or pipe they can test successfully. They rely on electromagnetic or ultrasonic waves to flow through the tube or pipe, and the end represents an abrupt change in the wall’s characteristics, making the test results difficult to interpret near the pipe or tube end. A new system overcomes the conventional obstacles by aiming clockwise, counterclockwise, and transverse transducers at a single point of entry. A timed delay based on the 1-kHz transmit frequency prevents the signals from interfering with each other, enabling the receiver to interpret the results accurately.

Tube producer beats the heat with portable cooling units

September 3, 2012

Many industrial processes generate quite a bit of heat, so keeping workers cool is a top priority. Wheatland Tube Co., Wheatland, Pa., added portable cooling units to lower the temperatures in its galvanizing and cutting areas. This initiative increased the time workers spend in these areas and eliminated heat-related incidents.
