A method is shown for installing a heat tube on a section of pre-insulated piping. A metal carrier pipe is covered with a first layer of foam insulation. Next, a routing device is used to cut a longitudinal slot along the length of the pipe so that the pipe exterior surface is exposed from the insulation. A heat tube is then installed within the longitudinal slot, whereby the heat tube contacts the exterior surface of the metal carrier pipe. A second layer of foam insulation is then sprayed onto the exterior of the metal carrier pipe, covering the previously formed longitudinal slot and installed heat tube. A polyolefin coating is then applied over the insulation to form a protective outer jacket for the insulated pipe.

Space in a conduit having at least one cable therein which is surrounded by a duct is recovered by longitudinally cutting the duct and removing the duct from around the cable. The duct may be pulled out of the conduit and past a blade to affect the cutting, or a blade may be pulled through the conduit to cut the duct while still in the conduit.

Cable pulling systems and methods of use are provided suitable for trenchless cable pulling applications, including bursting head applications for laying down replacement pipe underground. A chassis is provided that accommodates laterally disposed piston assemblies, both single cylinder and dual cylinder closed path piston assemblies. Also provided are quick release manifolds for cable holding grippers and cable pulling grippers for use with both single cylinder and dual cylinder piston assemblies. A chassis and cable pulling system also are provided for trenchless pipe extraction applications and which accommodate closed path piston assemblies. Small and large pipe diameter bursting head devices also are provided with integrated cable gripping and release assemblies. Also provided are methods for sealing cable ends.

An unlaid slabbing apparatus capable of profiling a roll of tissue material by determining the diameter, circumference, and weight of the roll. The slabbing apparatus calculates the amount of material to be removed based on operator input and predetermined parameters of weight, diameter, and density.

Cutting tools are provided for scoring a hose over a fitting. The cutting tool includes a handle with a central pass-through for the hose, and a scoring mechanism adjustably coupled to the handle. The scoring mechanism includes a base member with a central pass-through for the hose, and which is adjustably coupled to the handle. The scoring mechanism further includes an arm-blade subassembly coupled to the base member. The subassembly includes a blade, and an arm with a blade-receiving recess, and a guide surface to contact and travel along a hose. The blade is coupled to the arm within the blade-receiving recess to extend a selected penetration depth from the arm. The arm is radially adjustable with adjustment of the base member relative to the handle to physically contact the guide surface to the hose and insert the blade into the hose the selected penetration depth.

Space in a conduit having at least one cable therein which is surrounded by a duct is recovered by longitudinally cutting the duct and removing the duct from around the cable. The duct may be pulled out of the conduit and past a blade to affect the cutting, or a blade may be pulled through the conduit to cut the duct while still in the conduit.

Pipe splitting apparatuses and systems including a replaceable blade, and methods therefor, are provided. In various examples, a pipe splitting apparatus includes an outer surface including a recess. A blade including a portion is disposed within the recess. A hardenable material is disposed within the recess. The hardenable material is configured to flow upon application to fill empty space within the recess and at least partially around the portion of the blade disposed within the recess. The hardenable material is further configured to harden after application to secure the portion of the blade within the recess and fix the blade to the pipe splitting apparatus.

A tube scraping tool comprises: a handle; and a blade, carried by the handle. The tool has first and second laterally spaced apart portions for engaging the tube outer diameter (OD) surface during a drawing of the tool along the tube. The blade has a cutting edge trailing the first and second portions during the drawing and laterally between the first and second portions.

A trimming tool suitable for trimming material from within a central opening of an annular seal member includes a tubular member extending along a tool axis, a cutter coupled to move with the tubular member, and a first and a second debris catcher mounted on the tubular member. The cutter includes a first cutting edge oriented to cut when the tubular member is moved in a first direction along the tool axis, and a second cutting edge oriented to cut when the tubular member is moved in a second direction along the tool axis. Each debris catcher includes a receptacle that is open toward the cutter and includes an outer surface with a tapered segment. The cutter is mounted to the tubular member at a position between the first and second debris catchers.
