Abstract
A projectile receiver for receiving and stopping a high velocity projectile used in testing duct pipe which serves as a housing for fiber optic cables, as well as a method of using the projectile receiver, are disclosed. The receiver has a perforated housing that contains a rubber end stop therein adjacent a removable cap. The opposite end of the housing is stepped down to a diameter equal to that of a duct pipe being tested. The projectile receiver may be quickly and easily attached to and detached from a duct pipe to be tested using a clamping device, so that a single projectile receiver can be used to test a plurality of duct pipes in succession.
Claims18
A projectile receiver for receiving a projectile from a terminal end of a section of duct pipe being tested, comprising:
- a first section including a first tube having a first inner diameter, the first tube having first and second ends;
- a cap releasably secured to the first end of the first tube, the cap having a resilient, compressible end stop secured thereto and received within the first tube when the cap is secured to the first tube;
- a second section composed of an apertured second tube having an inner diameter, the second section having first and second ends, wherein the first end of the apertured second tube is coupled to the second end of the first tube;
- a third section including a third tube having first and second ends, the first end of the third tube being coupled to the second end of the apertured second tube and the second end of the third tube being shaped and dimensioned for selective coupling to a duct pipe.
The projectile receiver of claim 1, wherein the first tube is manufactured from metal.
- 10.The projectile receiver of claim 9, wherein the metal is steel.
A method of testing a section of duct pipe for continuity and lack of obstruction using a projectile receiver including a first section including a first tube having a first inner diameter, the first tube having first and second ends;
- a cap releaably secured to the first end of the first tube, the cap having a resilient, compressible end stop secured thereto and received within the first tube when the cap is secured to the first tube;
- a second section composed of an apertured second tube having an inner diameter, the second section having first and second ends, wherein the first end of the apertured second tube is coupled to the second end of the first tube;
- a third section including a third tube having first and second ends, the first end of the third tube being coupled to the second end of the apertured second tube and the second end of the third tube being shaped and dimensioned for selective coupling to a duct pipe;
- the method comprising the following steps:
- securing the second end of the third tube to a terminal end of a section of a duct pipe having an inner diameter substantially equal to the inner diameter of the third tube, the cap of the projectile receiver being secured to the first tube of the projectile receiver;
- placing, under pressure, a projectile in a first end of the section of duct pipe to be tested;
- receiving the projectile in the projectile receiver;
- removing the projectile from the projectile receiver;
- and
- detaching the projectile receiver from the section of duct pipe.
