A multiple flexible high pressure fluid cleaning lance drive apparatus includes at least a first drive motor having a first drive shaft, a spline drive roller mounted on the first drive shaft, a plurality of cylindrical guide rollers extending parallel to the spline drive roller, an endless belt wrapped around the spline drive roller and the plurality of guide rollers, and one or more follower roller modules each supporting a plurality of follower rollers for pressing against a single flexible lance. Each follower roller module independently presses its follower rollers toward the endless belt to grip the flexible lance sandwiched therebetween. Each module has an elongated block shaped housing having a central axis, a plurality of pneumatic cylinders and a piston rod carried in each pneumatic cylinder supporting a pair of spaced follower rollers that ride on the flexible lance captured between the endless belt and the follower rollers.

A method for cleaning a plurality of heat exchange surfaces; said method comprising: programming of an impulse wave cycle into a configurable controller in communication with a distribution network; transmitting an impulse wave through said distribution network to an outlet; measuring a plurality of pressures at a first location by a pressure sensor at said outlet; comparing at least one of said plurality of pressures from said measuring step with a programmed threshold pressure at said configurable controller; determining that one of said plurality of pressures corresponds to said programmed threshold pressure; completing impulse wave generation at said first location in accordance with said determining step; and moving said distribution network to a second location in response to said measured pressure corresponding to said threshold pressure.

Water-jet cleaning system and a method of cleaning a heat exchanger. The equipment includes a rotary tool having a lance with at least two degrees of freedom. The lance's movements relative to openings defined in the heat exchanger face plate are controlled via a smart indexing controller. The controller includes an electronic communication device that is specifically programmed to selectively activate various components of the rotary tool and a water delivery system. The programming utilizes an observed, learned, or uploaded pattern of the heat exchanger tube openings to selectively rotate the lance relative to the rotary tool's mounting assembly or linearly move the lance towards or away from the mounting assembly. The controller moves the lance to align a nozzle thereon with a selected opening in the face plate and then delivers a high pressure water jet therethrough.

A spray washing cart apparatus, including: a cart (10); a nozzle array holder (14); at least one cleaning nozzle array (16.1) arranged on the nozzle array holder (14), the cleaning nozzle array (16.1) including a plurality of spray nozzles (18.1) for spray washing; a water distribution manifold (20, 22) for supplying water to the cleaning nozzle array (16.1); and a water pump (24) connectable to the cleaning nozzle array (16.1) through the manifold (20, 22), wherein the water pump (24) is mounted on the cart (10), wherein the cleaning nozzle array (16.1) extends in a first direction (1), and wherein the nozzle array holder (14) is mounted on a top side of the cart (10) to be linearly moveable in a second direction (2) transverse to the first direction (1).

A heat exchanger cleaning device is provided. The cleaning device includes a drive motor configured to rotate a gearbox, a slip clutch, and a support beam about a first axis. The support beam carries a thread rod, a second motor, and one or more carriage assemblies. The carriage assemblies move linearly as the second motor rotates the threaded rod. The carriage assemblies include a support tube for receiving an ultra-high pressure tube therethrough. The carriage assemblies adjust relative to the heat exchanger such that the UHP tube may be inserted through the support tube into a hole of the heat exchanger. Therein the UHP tube may be advanced to clean sediment from the heat exchanger tube.

A shockwave supply device includes: a shockwave generating unit configured to generate a shockwave; a shockwave emitting unit configured to emit the shockwave; a conduit that is bendable and is provided at a part of a flow path of the shockwave from the shockwave generating unit to the shockwave emitting unit; a plurality of outer shell tubes provided outward in a radial direction of the conduit and provided along an axial direction of the conduit; and a coupling portion with which adjacent ones of the outer shell tubes are coupled to be rotatable with respect to each other about a vertical axis.

A grit blasting arrangement for cleaning chemical reactor tubes includes means for ensuring the grit blast nozzle is coaxial with the longitudinal axis of the tube to be cleaned.

A device and system are disclosed to clean the interior of tubes in air-cooled heat exchangers. The device is attached at each end of a tube by electromagnetism; either directly to a ferromagnetic tube header, or to a ferromagnetic plate secured to a non-ferromagnetic plug-type header or to a plate-type header of any metal. High pressure air with entrained dry finely-divided abrasive is conducted through a nozzle supported by the device. At the other end of the tube, another device supports a nozzle that captures the air, spent abrasive, and removed material. Spent abrasive and removed material are separated by filtration from the air before the air is exhausted to the environment. Tubes are cleaned to a bright metal condition, suitable for inspection or application of a corrosion-resistant coating, or to a lesser level of cleanliness appropriate for return to service.
