Pipe flange alignment leveling pins are disclosed to square a flange. The pins include a first and a second cylindrical magnet each configured to have a hollow axis and a positive radial pole and a negative radial pole. A first and a second chamfered hollow pin are engineered to axially receive a respective cylindrical magnet, the chamfer of each pin on an end configured complementary to a flange hole chamfer. A non-magnetic core is engineered to axially slide in and out of the hollow axis of the magnets received into respective pins wherein each of a pair of apparatus resemble a bow tie in cross section configured to align a pair of flanges in two places for a level operation. A level is set across a first and a second assembly of chamfered pins to determine a level flange ready for welding.

A reactor measurement-pipe maintenance clamp apparatus includes a first clamp mechanism and a second clamp mechanism. The first clamp mechanism includes clamps to fix the measurement pipe between the clamps, first clamp operation bolts that are allowed to be turned by remote control from above a reactor core, and wedge mechanisms to convert the turning of the clamp operation bolts to displacement of the clamps in a radial direction of the diffuser to generate clamping forces for securing the measurement pipe. The second clamp mechanism includes a support clamp to hold the support, a second clamp operation bolt that is allowed to be turned by remote control from above the reactor core, and a wedge mechanism to convert the turning of the second clamp operation bolt to displacement of the support clamp in a tangential direction of the diffuser to generate clamping force for fixing the support.

Apparatus for assisting in weld assembling a box column from a tack-welded pre-assembly of planar plate components. The apparatus features (1) an elongate frame defining a rotational-assembly axis, and (2) plural pre-assembly-receiving, rotational support structures mounted at spaced locations on the frame—each support structure including (a) an openable/closable yoke possessing a collar-reception zone, (b) an openable/closable collar rotatably receivable within this reception zone, and possessing a central throughpassage having a cross-sectional configuration which is larger than that of a box-column which is to be assembled, and (c) a pair of removably-collar-attachable, throughpassage clamping shoes for forming cooperatively, within the collar throughpassage, a window for complementarily, receiving extension therethrough of a box-column pre-assembly's cross section. A so received pre-assembly is rotatable about the rotational-assembly axis to position the existing seams of adjacency between the pre-assembly plate components for full-strength welding by an automated, traveling welding instrumentality.

A pipe mount for connecting pipe sections is disclosed. The pipe mount comprises a sliding member movably attached to a plumbing arrangement element. The sliding member extends in the vertical direction of the plumbing arrangement element, and it is vertically movable between an extreme position and a second position. The pipe mount further comprises at least one pipe bracket for securing the pipe sections onto the sliding member. A system and a method for connecting pipe sections are also disclosed.

A method for mutually positioning tubes. End faces, which includes a generally annular and generally circular end surface near an inner surface of the tube and a beveled edge surface connecting the end surface to an outer surface of the tube, are provided on first and second tubes, respectively. Plural clamping cylinders are engaged with the first and second tubes, respectively. Each cylinder is radially arranged onto and evenly distributed around respective tubes. The first and second tubes are pre-positioned relative to each other such that their respective end faces are opposite each other. At least one radial offset is assessed between the respective end surfaces of the first and second tubes. The clamping cylinders of the first and/or second tube are moved relative to each other in accordance with the assessed radial offset based on an optimization of areas in which their respective end surfaces coincide.

An apparatus for aligning sections of pipe includes a first clamp member and a second clamp member coupled with the first clamp member. The first and second clamp members each include a first clamp jaw and a second clamp jaw longitudinally spaced from the first clamp jaw. Each one of a first plurality of turnbuckle assemblies is coupled with each one of the first and second clamp jaws of the first clamp member, and each one of a second plurality of turnbuckle assemblies is coupled with each one of the first and second clamp jaws of the second clamp member. An assembly made from a kit of components is also disclosed. The kit includes an apparatus for aligning sections of pipe, and a plurality of shoe inserts. The assembly includes the apparatus and at least two of the shoe inserts coupled with the apparatus.

A pipe support has an outer tubular support wall, an inner tubular support wall, spaced inwardly from the outer tubular support wall, and a connecting portion for maintaining the outer tubular support wall and the inner tubular support wall in a fixed, spaced apart relationship. The pipe support is intended for use in-trench and out-of-trench for supporting a pipeline during assembly, installation, testing and operation.

A clamp is provided for mounting to a cable. The clamp has attachment means for connecting to a pipeline. Further, the clamp has plural clamp segments each with a curved section and tension devices connecting the clamp segments to each other to form a cylindrically shaped attachment area for accommodation of the cable in contact with the curved sections.

A design for tank fabricating equipment and system comprises a frame supporting opposing arms for supporting one or more tank shells. The opposing arms pivotally engage opposing sides of the tank shells to force them into a circular cross-sectional shape. The arms are provided with rollers for aligning the tank shell with adjacent components during fabrication. In some embodiments, the rollers are provided with a circumferential channel to accommodate welding seams and to ensure alignment of butt joints.

A pipe machining carriage, including a carriage configured to travel along an outer circumference of a pipe, and a chain coupled to both ends of the carriage wraps around the outer surface of the pipe. The carriage and the chain precisely move along the outer surface of the pipe. The disclosure may provide a carriage that performs machining with high accuracy by preventing the carriage from deviating from the original mounted position by moving the chain along with movement of the carriage. The disclosure may also provide a carriage mounted stably on the outer circumferential surface of the pipe to machine the pipe, regardless of pipe diameter, by adjusting a distance between the carriage drive wheels. The disclosure may prevent the carriage from slipping by mounting a front wheel and a rear wheel to the same drive shaft so the front and rear wheels rotate simultaneously in response to motor operation.
