b eNdiNg & T ube m aNipulaTioN Swaging systems and tooling The TubePro WeldLock system locks the tube in the tubesheet, precisely sets the tube protrusion and centres the tube in the hole, while leaving small air gaps that allow weld gases to escape during the welding procedure. The TubePro WeldLock tooling’s automatic centring process sets the weld gap between the tube and the tubesheet hole constant throughout 360° of arc at the tubesheet face, in around six seconds. This system eliminates the need for tack welding, or lightly rolling tubes in place to prevent movement prior to welding or tube-to-tubesheet expansion. This is said to enhance the quality and consistency of the finished weld, whether performed with automatic orbital welding equipment or by manual welding methods. HYDROPRO Inc, USA, manufactures systems and tooling for hydro-forming or swaging. The company’s equipment can full depth expand a 400mm (15.75") expansion zone in just a few more seconds than it takes to expand a 40mm (1.57") zone. The expansion pressure and dwell times can be precisely set and controlled to accommodate different tube material characteristics, which is of particular use when using tubes with high spring-back properties such as titanium and super duplex stainless steel. HydroPro’s SleevePro system uses hydroexpanding technology to expand sleeves or liners inside damaged parent tubes, to repair cracks or strengthen eroded or corroded tubes. The BoilerPro system mechanically sets and flares the ends of boiler tubes prior to hydroexpanding or mechanically rolling the joints.

Custom-made bending machines

DYNOBEND, The Netherlands, manu- factures a wide range of bending machines, specialising in custom-made machines to meet customers’ requirements. The company’s latest developments focus on the possibilities for automation in the bending process, for customers in industries such as heating/cooling, furniture and automotive. Automation can range from automatic loading to complete functioning production cells. In these production cells it is possible to work with loading systems, weld seem detection units, transfer units, robots, cutting systems, drilling/punching and even end- forming machines. Camera systems are used for checking bend quality, and can assist in creating a work cell with higher output.

The company states that, providing bending is the main process, it is able to complete any working cell. When suitable machines are available, the company buys them and integrates them into the process. If the right machine cannot be found, the company develops one to fit the requirements. The bending machine in the process is the master, meaning that the computer of the bending machine regulates all the other processes. Dynobend BV – The Netherlands Fax: +31 53 850 7731
