Tube piling equipment EZTM JSC specialists have designed a piler intended for the automatic forming of six- sided and quadrilateral tube batch. The simultaneous movement of trucks with the shapers is carried through mechanical linkage of the integral double- rack gearbox, transmission shaft and electric drivers. Piler construction calls for standardisation and a modular approach to the building of tube collecting mechanisms. This simplifies equipment maintenance and reduces machining on-stream time. The company’s designers have anticipated the necessary means and THE super Turbo-X 510 MKIII RTC series are high speed and high accuracy CO 2 cutting laser machines. The machines are equipped with high technology rigid table and constant optical length which assure an excellent cutting quality and high level accuracy in every point of the cutting table. The new generation resonator ensures cutting stability on the whole table’s surface. The resonator is integrated in the machine structure to guarantee maximum cutting reliability and stability. The laser beam produced by the resonator is sent to the

runs. The enhanced accuracy and repeatability of the Protemmachines can lead to a reduction in the number of weld defects. Accurate end profiles mean that more advanced welding processes can be employed. Many automated welding systems need very accurate fit-up, and are unforgiving if there are inaccuracies in the weld preparation. If an estimator can judge more accurately the time taken to perform end profiles, the total time allowed for the operation can be more easily quantified. tapping and chamfering unit with automatic tool change is composed by six tools (M3 – M10); Opti – Pod device for nozzle change, nozzle spatter removal and focal point calibration. The new PFP torch + IMS system, monitor processing cycle during different steps of cutting. Every machine can be easily integrated with CELL and FMS systems, allowing any type of production variations and guarantee the maximum productivity, 24-hours a day and even unmanned operation.

focus torch through a special beam delivery system, which always maintains constant beam path. Thanks to the laser beam’s unique features, Super Turbo-X 510 Mk III RTC performs automatic cutting of different materials and thickness, without additional machine set up. There are three different powers available for Super Turbo-X 510 Mk III RTC: 1.8KW, 2.5KW and 4KW. The machine is characterised by a Z axis stroke of 430mm for the processing of bent parts; a ‘C’ axis chuck for the processing of pipes from diameter 20mm to 375mm;

Importance of pipe end preparation prior to welding

NO matter which method is used for joining tubular components, whether welding, threaded joints or pressure-energised couplings, accurate end preparation is essential. Methods of end preparation vary from the simplest, such as a hacksaw and file, to high-tech, high-volume CNC production machinery that can turn out hundreds of finished tubes or pipes per hour. Protem can specify machines that are the most suitable for customers’ applications. Factors to be considered include: the parts to be welded, and their dimensions and

features; which cadencies and tolerances are to be held, and under which conditions – in workshops, on-site, in a controlled area, under very high or very low temperatures; whether the inside part of the tube can be touched with foreign elements such as a clamping mandrel or a clamping collet, or only the outside part must be touched; and the final purpose and the tube. Accurate end preparation of tube ensures that, where lengths of tube are to be joined to each other or to other components, the squareness of the tube end will guarantee proper fit-up and correct alignment on long
