A header delivery system and method for performing a pigging operation on a process tube connected at an angle to a header pipe. The header delivery system includes a base assembly coupled to a rotation assembly. The base assembly has a frame member supporting a launcher pipe coupled to a tube coupler and a jack apparatus. The rotation assembly is configured to position the base assembly with respect to the rotation assembly to adjust an angular position of the base assembly. The header delivery system may be aligned with a process tube in the header pipe and the jack apparatus may position the tube coupler from a first retracted position to an extended position to form a seal between the tube coupler and the first process tube. A service operation may be performed on the first process tube with the tube coupler in the extended position.

A header delivery system and method for performing a pigging operation on a process tube connected to a header pipe. The header delivery system is insertable in the header pipe and has a launcher pipe for launching an inspection or cleaning tool to the process tube. A tube coupler for coupling to the process tube and a bumper are connected to the launcher pipe. A jack apparatus is configured to position the tube coupler and the bumper. A wedge assembly is connected to the launcher pipe and has a first actuating wedge and a first extension wedge. A first linear actuator is connected to the first actuating wedge and is configured to move the first extension wedge and the tube coupler mount apart from one another to position the tube coupler and the bumper from a retracted position to an extended position.

A cleaning ball with a naturally derived material bonded to a surface of the cleaning ball for a condenser in a power plant is capable of performing efficient cleaning, and even if the material bonded to the surface of the ball is discharged to the ocean, the material does not cause damages to a marine environment. The cleaning ball includes a sponge rubber ball configured to deform and clean a heat transfer tube of the condenser; and a skin layer including crushed sand bonded to a surface of the sponge rubber ball. The crushed sand comprises sandstone containing granite particles, and the crushed sand has a particle size between 0.05 mm and 2.00 mm, and the skin layer is formed in concave and convex shapes on a non-deformed shape of the sponge rubber ball, and is configured to deform corresponding to deformation of the sponge rubber ball.

An apparatus for the maintenance and operation of an air-cooled heat exchanger (ACHE) includes a plurality of spray tubes provided with spaced-apart nozzles permanently positioned between the finned heat exchange tubes and longitudinally aligned within the region of the finned-tube pitch. The apparatus is operable in several modes, including cleaning where the flow of air is stopped and temperature-controlled pressurized water with an optional cleaning agent is discharged from the nozzles to dislodge dirt and debris from the finned surfaces while simultaneously cooling the hot process liquid. When extremes of ambient air temperatures preclude the forced air fans from achieving the target temperature range of the process liquid passing through the ACHE, refrigerated pressurized cooled water and compressed air in the form of a mist is discharged from the nozzles, or alternatively, pressurized heated air is discharged from the nozzles.
