INFLATION METHOD PIPES PVC

[1]

The present method includes inflating of PVC pipes, and particularly those used for the passage of optical fibers , without any deformation, without altering , regardless of the diameters or lengths of said tubing.

[2]

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.

[3]

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.

[4]

The method provides that includes adhering a sealed tip to each of the ends of the tube , the originating and equipped with a valve and an anti-reflux valve.

[5]

The shèmas herein, give an impression of much more accurate 1' utiltsation hardware referenced.

[6]

The gain resulting from the application of my process is not only at the reduced price of used equipment , but particularly the reliability of the result obtained.

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.
