When removing tubes from a vessel, one of the most difficult tasks can be removing tube stubs from the tube sheet. Depending upon how long the tube has been in the vessel, in addition to how efficient the initial expansion was, the removal process can be very difficult.
The factors affecting a Tube Bundle Cutter’s performance are: bandsaw blade selection, blade tooth pitch, cross-sectional area of the bundle, blade speed and feed.
One of the most common methods for cleaning chillers, condensers, and other heat exchangers are rotary tube cleaners. With several brush styles to choose from, rotary tube cleaners can remove a variety of deposits. To achieve the best cleaning results, it is important to properly size the brush according to the brush style and the deposit being removed.
Cleaning tubes increases energy efficiency. Every tubed vessel (ex: boilers, heat exchangers, condensers, chillers, etc.) requires the surface of the tubes to be clean and scale-free to function efficiently. If deposits or scale are present, the flow through the vessel and the efficiency of the vessel decreases.
Provided in the Elliott Tube Gauge kit is a setting ring, screw driver, and wrench. Indicated on the setting ring is the proper calibration diameter for the gauge.
Loss of productivity, downtime, and decreased roll quality are all possible results of avoiding routine care of pneumatic motors. These issues require the motor to be removed from operation and examined and possibly sent back to the manufacturer for repairs – possibly delaying jobs.
Some of the most overlooked best practices of tube expansion involves the use of pre-expansion tools. In order to create a better mechanical joint and prolong tool life, it is important that the appropriate pre-expansion tools are used.
"We pulled 10 times as many tubes with Elliott's spears, eliminating wasted labor and increasing our production."
"AREVA expects to double the tube removal speed by using the Elliott Cyclgrip tool. Since this tool only requires two people, AREVA can use other personnel more effectively."
Elliott's One-Rev deploys more advanced engineering principles with over 12 key differences that result in a superior product. The One-Rev cutter blade is designed to withstand even the toughest of materials.
