PIPE PRESSURE TESTING AND CLEANING APPARATUS |
摘要 |
Method of an apparatus for pressure testing and cleaning pipe in which one or more pipes are secured to a treatment manifold (31). The or each pipe is then filled through one end with low pressure water via an inlet (40) in the manifold (31), the other end of the or each pipe including a self-bleeding valve (52) which closes once the air within the pipes has been evacuated. The pressure is held for a predetermined time and the pressure sensed by a visual gauge (14) and a paper read-out (16) so that any pressure drop indicative of failure is noted. The pressure is then released, the valve (52) removed and the high pressure water at a pressure between 500-8000 psi introduced through jets (35) to wash the pipes which are then dried with compressed air before removal. |
