System and method for cleaning heat exchanger tubes

A system and method for cleaning of heat exchanger tubes including an assembly, an indexer, and a communication device provided with specialized software and programming. The indexer includes orthogonally arranged first and second arms. A trolley and sensors are provided on the indexer arms. One or more lances are provided on the trolley to deliver water jets into the openings. Sensors measure displacement as the trolley is moved relative to the heat exchanger's face plate. An operator controls the system from a distance away using the communication device. During setup, the pattern of the face plate is learned and mapped utilizing information from the sensors as one of the inputs. This information is utilized to help navigate the face plate during a subsequent cleaning operation. A kit for retrofitting existing X-Y indexers is also disclosed.

Vapor abrasive blasting system with closed loop flow control

A blasting system includes a pressure vessel, water pump, blast circuit, motor, orifice valve, and controller. The pressure vessel is configured to contain a pressurized blast media slurry. The water pump pumps water from a water supply to the pressure vessel. The blast circuit delivers the pressurized blast media slurry received from the pressure vessel. The motor drives the water pump. The orifice valve regulates a rate of flow of the blast media slurry to the blast circuit. The controller provides control commands to the water pump or the orifice valve based on a blast media flow rate set point and at least one sensed operating parameter.

SYSTEMS AND APPARATUS FOR USE OF WET RECYCLED ABRASIVE AND METHODS OF OPERATION OF SAID SYSTEMS AND APPARATUS

Disclosed herein are components, systems, and methods of operating an abrasive fluid jet system that recycles and reuses abrasive particles. The systems and methods described enable accurate metering and consistent feeding of wet abrasive particles thereby reducing the time and cost of operations associated with drying the recycled abrasive particles prior to reuse. The system may adjust a ratio of wet abrasive to dry abrasive being provided to a cutting head to form an abrasive fluid jet. Components of the system may overcome challenges associated with clumping and other issues that result in difficulty metering wet abrasive.
