摘要： A cutting head assembly uses multiple cutting heads directing ultra-high pressure fluid in different directions towards an inner surface of a pipe to be cut in order to complete a full cut of the pipe while rotating or revolving the multiple cutting heads less than 360 degrees relative to central axis. The ultra-high pressure fluid mixes with abrasive inside fittings on or near each of the nozzles to further assist with cutting through the pipe. Some cutting head assemblies have two nozzles, while other cutting head assemblies have three or four nozzles.

摘要： A nozzle for water jet equipment and a method of use thereof. The nozzle has a body including a base with a shaft extending outwardly therefrom. The shaft is inserted through a bore of a sleeve that rotatable about the shaft. The base and shaft define a bore therein. At least one opening is defined in the shaft and one or more grooves are milled into the shaft's exterior surface. Each opening places the body's bore in fluid communication with one of the grooves and the sleeve's bore. Water flowing through the body's bore will flow through each opening, into the associated groove and into a space between the shaft and sleeve. The shaft terminates in a conical section usable as a battering ram to break up blockages in pipes during cleaning operations.
