Method for inflating PVC pipes
The present method includes inflating of PVC pipes, and particularly those used for the passage of optical fibers To date inflation is attained by placing at one end of said tubes a thermoplastic seal and at the other end of an inflator system heat-welded. Irreversibly As a result the deformation of these PVC pipes, sasceptible be the calibration interior of said tubing and the free passage of cables which pass. The method provides that includes adhering a sealed tip to each of the ends of the tube The shèmas herein, give an impression of much more accurate 1' utiltsation hardware referenced. The gain resulting from the application of my process is not only at the reduced price of used equipment Method intended to pressurise PVC pipes without deformation or damage to the said pipes. <IMAGE> 1) The inflator pipes comprises a stopper of P.V.C. P.V.C. with thread (3) and having an orifice. 2) In the opening in the plug fits a nozzle check (1) with washer (2) secured to the plug (3) by a nut (6) with its washer (5). 3) The inflator thus obtained is thereafter bolted to '1' P.V.C end of a pipe. 4) Sealing is obtained by a washer Neoprene Heald (4). 5) P.V Upon inflation of the pipe. C., a lid (7) is screwed on the nozzle check (1) thereby completing the inflator. INFLATION METHOD PIPES PVC
