Abstract

401,621. Testing tubes for leakages. TRAUT, R., 69, Friedrichstrasse, M³lheim Ruhr, Germany. July 13, 1933, No. 19891. Convention date, Oct. 27, 1932. [Class 106 (ii).] In a process for testing the fluid-tightness of steel or cast-iron tubes wherein all the steps are carried out automatically, the apparatus is constructed so that two or more tubes of various lengths may be simultaneously secured in the testing position. The tubes 1 to be tested are fed in pair intermittently by conveyer chains 23 from a surface 41 to the testing position between opposed pairs of nozzles 12, 17. A cam shaft 30 rotated continuously by an electric motor 32 operates an air control valve 35 to actuate a piston 10 and advance by means of pivoted links 8, 7 an abutment 6 carrying the nozzles 12, which thus engage one end of the tubes 1, and force the other end into the nozzles 17. The latter are held in a fixed, adjustable slide 15 by means of rams 16 subjected to air pressure from a cylinder 19 acting on water. A contact disc 37 on the shaft 30 completes the circuit through electromagnets 38 which are advanced together with the abutment 6 and draw the tubes 1 downwards into the jaws of the conveyer chains so that they are not bent during the clamping. The cam shaft 30 now operates a valve 36 to admit water to the tubes 1 by way of a distributing member 14, the pipe 13 and the nozzles 12, the air in the tubes 1 escaping by a valve 18. After the water pressure test has lasted a few seconds, the valve 36 is operated to discharge the water from the pipe 13, and the air valve 35 is operated to withdraw the abutment 6, thus releasing the ends of the tubes 1 from the nozzles 12. Further movement of the abutment 6 causes the electromagnets 38 to be moved by stops 40, and this moves the tubes 1 to release their other ends from the nozzles 17. The contact disc 37 now breaks the electromagnet circuit and the tubes 1 are free to be moved by the conveyer chains to the other side 42 of the machine.
