Stainless steel and nickel alloy tubes

Serially, the X-Ray 6000 Triax includes a statistical analysis of the measuring results and their graphical presentation in a length or time-related trend diagram (with zoom function). This is combined with a graphic for the distribution of the single values (statistical distribution curve).

steel tube range of 0.3 to 76mm and wall thickness from 0.1 to 3.5mm. These tubes are produced using stainless steels provided and guaranteed by leading steel mills. ISO 9001:2000 accredited by Italcert, the company has been certified by RINA for its welding system and heat treatment for the production range of OD 6-19mm and wall thickness of 0.4 to 1.1mm.

Tecnofar SpA, Italy, is a specialist in the manufacture of stainless and nickel alloy tubes. With advanced technology, the company has two production units, located in Delebio and Gordona, covering a total surface area of 7,000m 2 . The company produces redrawn precision tubes, both in bar and coil form, using the TIG welding process. The company offers a modern, well-equipped department for tube cutting and is able to produce cut pieces measuring just a few millimetres in length, completely burr-free. Tecnofar can adhere to a range of dimensional tolerances, with a stainless

Automotive radiator leak test kits

Tecnofar SpA – Italy Fax : +39 0342 684500 Email : info@tecnofar.it Website : www.tecnofar.it

During the manufacture and later repair of automotive radiator and cooler systems, together with their associated pipe/tube connections, it is necessary to test for leaks. Leak testing has been carried out in the past by random methods and the use of brass plugs that jam and become difficult to use after some time, because of the nature of the testing medium. The Pipestoppers division of Huntingdon Fusion Techniques Limited manufactures test kits for the leak testing of all sizes of tubes, pipes and orifices associated with the manufacture and subsequent repair of radiators, coolers and intercoolers for cars and larger vehicles. The kits have machine cut foam insert positions for the plugs so that they can be replaced after use to allow easy location for future requirements. Each kit contains a number of same-size plugs, covering the range from 0.5 to 2" (12-75mm). For commercial vehicles, the size range is 2.5 to 6" (75-150mm). The plugs are manufactured from Nylon 6, a high quality engineering plastic that is resistant to the acidic and alkaline liquid environments sometimes encountered in such high volume testing applications. A natural rubber ring is contained between top and bottom plates located over a central threaded, hollow shaft. A wing nut screwed onto the shaft pushes the two plates together, expanding the rubber ring to fit the orifice to be sealed. A Delrin friction-free washer under the wing nut makes tightening and loosening very easy.
