Tube expansion tools make expanding multiple high-pressure tubes easier

hold, purge and many more settings that will maximise the efficiency of a tube expansion operation. The tools are designed to accurately and safely expand tubing with dimensions ranging from 0.38" to 1.00" in outer diameter. Many different tube materials can be expanded. The tools can be custom configured with pre-grip handles, no handles, or air actuated pre-grip and can accommodate tube swallows of up to four inches. The key benefit to using these hydro expansion tools is that they efficiently

AIRMO Inc ® Pressure Technologies is a manufacturer of ExpanTek ® tube expansion tools. Its Model 180 series tools are ideal for expanding copper tubing into conduction fins during the manufacturing of heat exchangers, coil assemblies and other HVACR products. The patented tools are designed to work with the ExpanTek Hydraulic Power Supply, which supplies the tool with up to 30,000psi (2,068 bar) of water, oil, or other service medium and has a digital control panel to adjust prefill pressure, expand pressure, dwell time

attach to a tube and hold under extreme pressure and do not damage the end of the tube during the expansion process. This eliminates the need to cut off the end of the tube where the tool was gripping it, which is a huge time saver in the production process.

High-tech 24" API chamfering line for German steel and tube manufacturer

performance spindle unit with up to 100kW continuous power ensures extreme cutting performance. The output of the machine, working in continuous operation, is secured for another 20 years. The machine housing is equipped with noise and emission reduction, therefore the chamfering machine will be safely and ergonomically operated. Due to the efficient Siemens drive and controller generation, this investment is a major contribution to reduce the company’s CO 2 value. The system can be operated entirely and easily by a self- explanatory Siemens S7 axis control in addition to the ergonomic changeover comfort.

by the new Reika 24" Model 382 CNC chamfering line. The chamfering line, located in the tube mill in Hamm, Germany has produced multi-million tons of API grade steel pipes over the past 24 years. The Reika chamfering line operates according to API standards and is used for preparing the steel tubes with a wall thickness range of up to 25.4mm and a material strength of up to 900N/mm² for line pipes and casing tubes. The line is equipped with a concentric, NC-adjustable 3-jaw clamping system and complete tooling system for different API angles and geometries. Fast changeover times are guaranteed by the quick tool change system with integrated handling device and integrated tool monitoring. A completely re-designed rigid high-

REIKA has received another order for the delivery of a chamfering line to one of its largest customers in Germany, a global manufacturer of steel tubes. The Reika chamfering line that is currently in operation has been in place since 1997 and will be replaced
