Abstract: Securing devices are shown and disclosed. In one embodiment, the securing device includes a base having a first channel. The securing device additionally includes a pair of clamp members received in the first channel. The securing device further includes an actuator member that is received in the first channel and that enables a user to simultaneously move the pair of clamp members toward or away from each other.

Abstract: A cutting machine with clamp assembly includes a saw blade, a worktable, and a clamp assembly. The worktable is adjacent to the saw blade and can move along a processing axis relative to the saw blade. The worktable includes a tabletop facing the saw blade, a processing area set on the tabletop and extending along the processing axis and corresponding to the saw blade, and a chute recessed on the tabletop and extending in the direction of the processing area. The clamp assembly can be operated to move along the chute. The present invention uses the clamp assembly to firmly press against the workpiece, thereby assisting the positioning of the workpiece and ensuring the safety of the user.

Abstract: 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.

Abstract: A system and method for providing a mandrel that can be used to react the loads that are created by a friction stir joining tool as it performs friction stir joining of tubulars, the mandrel selected from a disposable mandrel, a partially disposable mandrel, a reusable mandrel, and a mandrel that is partially disposable and partially reusable.

Abstract: A foldable workbench comprises at least a foldable leg frame, two clamp assemblies, to angular control board, several angular regulators, several clamp boards and a flat workbench, in which two clamp assemblies are linked to the foldable leg frame. The adjusting holes of the angular control board are connected to one side of clamp assemblies. Several angular regulators are arranged at both ends of the clamp assemblies. In addition, several clamp boards are bolted on the angular regulators. The flat workbench is placed on the angle iron rake of the brace.

Abstract: An apparatus for gripping a pipe, which apparatus comprises an outer member having a first inclined inner surface, and an inner member having a first inclined outer surface, the arrangement being such that, in use, on rotation of said outer member relative to said inner member in one sense said first inclined inner surface co-operates with said first inclined outer surface so that said inner member moves towards a pipe to be gripped.
