A method for cleaning the interior of a pipe using a cleaning device which has a tube. The tube is set into an axial movement along a main axis H within the pipe, and the insertion depth E of the tube into the pipe is detected. It is determined whether the tube has reached an end position, and the axial movement is terminated when the tube reaches the end position.

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 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.
