A pipeline field joint abrasive blast cleaning machine is disclosed in which direct contact between the pipe to be cleaned and drive rollers of the machine ensure a constant, known distance exists between the blast nozzles of the machine and the pipe surface. This ensures uniform application of abrasive matter to ensure uniform cleaning of the pipe surface.

A scraper assembly configured to traverse an exterior surface of a tubular member is disclosed. The scraper assembly includes a casing constructed and arranged to drive the scraper assembly to traverse the exterior surface of the tubular member and a primary ring fixed to the casing, having a plurality of projections formed of a semi-rigid material extending inward toward the exterior surface of the tubular member. A water treatment system including the scraper assembly is also disclosed. A method of retrofitting a water treatment system including providing the scraper assembly is also disclosed. A method of removing organic material fouling from an exterior surface of a quartz sleeve is also disclosed. The method includes directing the scraper assembly to traverse the exterior surface of the quartz sleeve.

A cleaning apparatus for cleaning a cooling tube array (15) of a heat exchanger has a nozzle carriage (16) movably held on a truss beam, and a plurality of cleaning nozzles (40) mounted to the nozzle carriage. A truss beam has two parallel C-channel rails (20) having back sides that face each other, a tube (22) arranged separate and distant from the C-channel rails and at a different height than the C-channel rails in a cross-sectional plane of the truss beam, and truss supports (24) connecting the rails and the tube; the nozzle carriage has rollers (48) that are arranged for travelling in the C-channel rails. A water intake (82) is coupled to the nozzle manifold (42) and to a hydraulic drive (80) having a mechanical power take-off member (96) that is operably coupled to the nozzle carriage (16) for moving the nozzle carriage.

The present invention relates to a shower hose cleaner having a new structure that can easily clean a shower hose connected to a shower head. The shower hose cleaner according to the present invention is configured to comprise a case 10 having a tubular shape extending in a longitudinal direction and a brush member 20 provided on an inner circumferential surface of the case 10, and the case 10 is configured to be able to be divided into two parts. When the case 10 is coupled to an outside of the shower hose 2 and slid in the longitudinal direction of the shower hose 2, an outer circumferential surface of the shower hose 2 is cleaned by the brush member 20, and the shower hose 2 can be easily cleaned.

An opening machining apparatus for a heat transfer tube, a method of machining an opening in a tube wall of a heat transfer tube using the same apparatus, and a method of removing a foreign material through the same opening are provided. The opening machining apparatus for the heat transfer tube includes an electric discharge machining device inserted into the heat transfer tube and configured to form an opening in a tube wall of the heat transfer tube through an electric discharge machining, an electric discharge machining device driving device connected to the electric discharge machining device and configured to transport the electric discharge machining device, an electric discharge machining device driving device connected to the electric discharge machining device and configured to provide force for bringing the electric discharge machining device into close contact with a tube wall surface of the heat transfer tube, and an electric discharge machining device rotation device configured to provide force for rotating the electric discharge machining device in a circumferential direction of the heat transfer tube in the heat transfer tube.

A skimming apparatus with a pivot arm and a drive follower on the pivot arm that guides a belting to facilitate precise placement of the belting for efficient skimming.

A washing and doping mechanism includes a bushing that is configured to engage a tubular that is in a substantially vertical orientation. The bushing is configured to rotate, thereby causing the tubular to rotate about a central longitudinal axis of the tubular. The washing and doping mechanism also includes a sprayer configured to spray a fluid onto the tubular in the substantially vertical orientation.

A robot is disclosed for cleaning the exterior of tubes of a heat exchanger. The robot comprises a lance for directing a jet of fluid into spaces between the tubes, a carriage for transporting the lance in a direction of travel parallel to axes of the tubes of the heat exchanger, and traction assemblies for engaging the tubes to enable the carriage to be advanced along the tubes, wherein the traction assemblies are each moveable relative to the carriage in a direction transverse to that of travel in order to change the track width of the robot.

A heat exchanger cleaning system is disclosed which is capable of determining the position of a lance within a tube bundle of a heat exchanger core. The system comprises a lance for directing a jet of fluid into spaces between the tubes of the bundle, an arm mounted alongside the lance and movable relative thereto, an abutment mounted to an end of the arm to sense an outer surface of the heat exchanger core, and a transducer for measuring the position of the lance relative to the arm to determine the extent of travel of the tip of the lance beyond the front face of the tube bundle.
