A coupling bolt hole alignment tool, a method to align two coupling holes, one in each of two coupling halves, and a system to align two coupling holes are provided. The coupling bolt hole alignment tool and system includes an expandable sleeve assembly configured to be inserted into the second coupling hole and secured into the second coupling hole with a wedge nut. A rotatable rod including an eccentric hole formed in one end of the rod is contained within the expandable sleeve assembly. A pin/paw assembly includes a pin and paw. The pin is inserted into the eccentric hole from the first coupling hole and the paw is disposed within the first coupling hole and includes a portion oriented against a wall of the first coupling hole. Rotation of the rotatable rod while the pin/paw assembly is held stationary by a restraining device aligns the two coupling holes.

An alignment tool device for use in aligning a manway cover to a manway body/flange during installation of the manway cover includes a first plate with an L-shape has body with a pair of holes and a first tongue extending transversely from the plate. A second plate with an inverted-L shape has a body with a pair of holes and a second tongue extending transversely from the plate. The first plate is oriented substantially parallel to and opposing the second plate with the first tongue extending parallel to and overlapping the second tongue, where the first and second tongues extend in opposite directions. A height adjuster displaces the first plate relative to the second plate by adjustable engagement of the tongues.

A tool for removing an annular part mounted around a shaft of a turbomachine, includes a holder configured to cooperate with a lifting system, a system for coupling and holding the annular part, the coupling and holding system being secured to the holder, the system for coupling and holding having an opening designed to receive the shaft of the turbomachine during the removal of the annular part, the coupling and holding system being rotatable with respect to the holder between a first position and a second position by a rotation system for tilting the annular part with respect to the holder when the coupling and holding system is fastened to the annular part.

A pipe flange is leveled for welding by using stainless steel using ball bearings attached to a U-shaped spring-loaded wire so a fitter is able to level a flange for welding while the wire supports a level. The ball bearings are part of a first leveling unit and a second leveling unit which comprise a flange leveling system. The spring acts to bias a first leg and a second leg of the leveling units such that the distal ends of both legs are biased toward each other. The ball bearings are axially co-linear with each other and are sized to be seated in bolt holes defined in the first and second sides of the pipe flange. A related process is also disclosed wherein the flange is adjusted until the associated flange holes on the first and second sides of the pipe flange are level with each other.

A pipe alignment clamp for use in pipe fitting/fabrication applications. The pipe alignment clamp has a generally circular frame with at least one hinge therealong to enable the clamp to be opened and subsequently secured around a pair of pipe segments and/or fittings to be joined. Threaded support members are positioned along the frame in spaced apart fashion, and extend outwardly from each side of the frame. The support members are used to support alignment screws that can be independently repositioned radially towards and away from the pipe segments and/or fittings to be joined, thereby enabling the alignment clamp to accommodate a wide variety of different shapes and sizes of pipe segments and fittings, and requiring a minimum length of pipe segment to operate. The adjustment screws may be manipulated by hand, or by a separate alignment screw tool, which may be included as part of a pipe alignment kit.

The present invention provides a clamping jig for tube connection with which it is possible to clamp tubes even in a small and narrow space. A clamping jig for tube connection 10 according to the present invention is a clamping jig for tube connection that clamps joint-equipped tubes 60, each tube including a protruding collar portion 63 at a position rearward of its leading end. The clamping jig for tube connection includes: a first member 20 that includes a first clamping portion 21 that is provided at a leading end thereof and to which one of the tubes is fitted, and a first gripping portion 23 formed at a base end thereof, a second member 30 that includes a second clamping portion 31 that is provided at a leading end thereof and to which the other tube is fitted, and a base end thereof being pivotally supported at the base end of the first member by a pivoting portion 27; a support rod 25 that extends from the first member through the second member; and a lever member 40 in which a leading end thereof is pivotally supported by a support portion 26 provided in the support rod, and a lever gripping portion 41 is formed at a base end thereof, the lever member 40 enabling swinging of the lever gripping portion in a direction of the base end of the second member, and the lever member 40 including a pressing portion 42 that presses the second member on the base end side relative to the support portion.
