摘要:
A hot bolt clamp and method for repairing a multi-bolt flange of a pipe. The clamp has enclosures that can be assembled around the multi-bolt flange. The clamp has a central opening extending through a first enclosure face and a second enclosure face for the pipe. The clamp includes a flange bolt cavities extending through the enclosure faces configured to enclose flange bolts and having a cutter channel connected to each flange bolt cavity. Restraint bolts extend through the enclosure face to restrain the multi-bolt flange. Flange bolts can be removed and replaced during the repair operation. A cutter tool apparatus can be extended through each cutter channel for use in removing stuck flange bolts. The clamp forms an injectable void around the multi-bolt flange that is injectable with sealant in the event of a loss of gasket integrity during the repair operation.

A tool for cutting and slitting the shielding of an electrical cable includes a cutting platform configured to engage the shield of the cable. A driven cutting blade is mounted for movement past the cutting platform into the shield. A fixture is provided for supporting the cable in a desired orientation during a cutting or slitting operation. The fixture includes a first cable support that defines a ring cut plane and a second cable support that defines a slitting plane.

The invention relates to a tool for longitudinally subdividing buried sewer pipes having an asymmetric, generally oval cross section, made substantially of a support shoe opposing a cutting blade acting in the direction of the pipe axis. The device also has two side cutting blades and is moved through the old pipe by means of a rod and a cylindrical calibration mandrel.

A device and method for pipe replacement is shown. A pipe replacement device is shown that includes at least one scoring wheel to provide a more progressive cut that provides consistency in the split of the pipe. A pulling force is reduced using pipe replacement devices and methods in a splitting operation. A pipe replacement device is shown that includes at least one skid structures with a long and consistent profile. In methods shown, friction between a pipe replacement device and the pipe being split is reduced.

The basic features of the invention include a pipe parting mole, a length of cable that is engagable to the mole, a cable pulling device and a cable pulling device engagement means that provides a mounting structure for the cable pulling device. The cable pulling device engagement means generally includes a reaction plate and a structure for removably engaging the cable pulling device therewithin. A cable pulling frame may be advantageously used to facilitate the removal of the cable from a relatively small hole that is created at the pulling end of the pipe.

A process for peeling an outer tube of a spent NaS cell, concluding the steps of: (1) holding opposite end portions of the spent NaS cell; (2) forming annular cut lines in the outer tube of the cell at the opposite end portions; (3) forming a straight cut line in the outer tube to be continued to the annular cut lines; (4) inserting a pawl into the straight cut line; and (5) peeling the outer tube of the spent NaS cell by turning at least one of the spent NaS cell and the pawl relative to each other. Instead of the pawl, a chisel may be inserted into the straight cut line, and the outer tube of the spent NaS cell is peeled by applying an impact force upon the outer tube of the cell through the chisel. Apparatuses for peeling the outer tube from the spent NaS are also disclosed.

A pipe slitter comprises a base for fixing the slitter to a pipe to be slit thereby. The base includes a pair of end plates for mounting transversely of the pipe and a pair of connecting rods for coupling the end plates to each other. The connecting rods extend longitudinally of the pipe. A carriage supports a slitter blade. The carriage is movably supported on the base for movemenet longitudinally of the pipe. The slitter blade is movably supported on the carriage for movement transversely of the pipe.

A die press consisting of: a bed on which a workpiece is supported in operating position; a die holder movable between a retracted position and an extended position; a workpiece holder mounted for movement relative to the bed between a holding position and a release position; and cooperating structure on the die holder, bed, and workpiece holder for moving the workpiece holder from its release position to its holding position as an incident of the die holder moving from its retracted position towards its extended position. The workpiece holder in its holding position maintains a workpiece in operating position on the bed.
