Abstract: The boiler cleaning apparatus and method provides for cleaning the exterior surfaces of a heat exchanger. The apparatus and method include tools and steps, respectively, for temporarily spreading tubes and holding open the tubes to gain access to tube lanes. Once access to a lane is attained, a nozzle assembly having an outlet for blowing high velocity cleaning fluid is selected from a group of nozzle assemblies. The selected nozzle assembly will have an outlet for blowing fluid in a direction that effectively cleans the tubes adjacent the opened lane. After the tubes are cleaned the tool for holding the lane opened is removed and the process is repeated for another lane.

Abstract: The invention concerns a family of insertable temporary fasteners (100) comprising the following: a body (101) with a bearing face (102) at least one clip (103) with a hooking spur (104) a threaded rod (105, 205) connected to the clip, with a control nut (107, 207) screwed onto the said rod The family comprises at least two temporary fasteners (100) with different diameters and nuts with different lengths (116). The invention also concerns a set comprising such a family of fasteners, along with an installation device (13) comprising a means (26, 30) of detecting the length of the nut.

Abstract: One example of the present disclosure relates to a method of applying torque to an object, which threadably engages a part. The torque is applied with a wrench, comprising a first handle, a second handle, a planetary gear mechanism, a drive that comprises an internal gear and an external gear, and a first pawl, movably coupled to the first handle and biased to contact the external gear of the drive. When the drive is coupled to the object, the method comprises transmitting an input torque to the drive by rotating at least one of the first handle and the second handle relative to the part. The first pawl is movable between a first position and a second position relative to the first handle may or may not operatively engage the external gear of the drive.
