Flushing nozzles
|
Flushing nozzles of PN type are purposed for tripping into the borehole a flush-joint pipe casing string on the one end of the bottom-hole assembling during the flushing operations.
The nozzles construction is characterizes by tangential incline of the stream holes for creating involute stream of the fluid; the holes are made in the hard alloy insertions that are soldered in the body.
It is possible to change the outside diameters and construction dimensions, also to produce coupling threads at a client's request.
