An adjustable clamp for welding together pipes, the adjustable clamp having a first axis perpendicular to the pipes and a second axis parallel to the pipes. The adjustable clamp includes four clamp corners, four transverse bolts, two parallel bolts, two threaded inserts, and four spaces. Each clamp corner includes a first transverse aperture, a second transverse aperture, and a third parallel aperture. The first and second apertures are transverse relative to the first axis and the third aperture is parallel relative to the first axis. Each transverse bolt is securable within the first and second transverse apertures of the four clamp corners. Each parallel bolt is securable within the third apertures of the four clamp corners. Each threaded insert is placeable within the third apertures of the four clamp corners and each threaded insert is mated with a respective parallel bolt. Each spacer surrounds a portion of each transverse bolt.

A chuck for gripping and moving cylindrical bodies, in particular fittings and pipe segments, including a main body defining an axis of rotation and a plurality of jaws fastened to the main body. The jaws are movable between a position of maximum closure, in which they are at the minimum distance from the axis of rotation, to a position of maximum opening, in which they are at the maximum distance from the axis of rotation. The chuck can adjust the positions of maximum closure and maximum opening and can move the jaws between the positions of maximum closure and maximum opening. The chuck also allows for the axial fixing of the chuck to a support member and for a connection of the chuck to the support member so that they are angularly rotatable with respect to each other.

An adjustable hose clamping arrangement for vacuum-tight sealing of a hose of a flexible insert to a free end of a steel branch of a vacuum mold. The adjustable hose clamping arrangement includes a clamping device configured for fixedly clamping the hose such that a relative movement between the hose and the clamping device is inhibited, a mold bracket configured for being mountable to the steel branch of the vacuum mold, and two connecting devices, wherein a first end of each of the two connecting devices is connected to the clamping device and a second end of each of the two connecting devices being opposite of the first end, is connected to the mold bracket such that an outer surface of the hose next to a free end of the steel branch is accessible for the vacuum-tight sealing between the hose and the free end of the steel branch.

A clamp includes a housing, the housing defining a first end and a second end; at least one tongue connected to the housing and extending proximate the first end; a gasket arranged within and in contact with the housing; and at least one clamping assembly coupled to the housing, wherein each clamping assembly engages at least one tongue.

A tool for assembling a hose and a connector, which includes a base, a hose clamping assembly, a connector clamping assembly and a drive assembly. The base includes an assembly axis . The hose clamping assembly is slidably connected to the base. The connector clamping assembly is rotatably connected to the base and the drive assembly is configured to drive the connector clamping assembly to rotate about the assembly axis while moving toward or away from the hose clamping assembly. The drive assembly drives the connector clamping assembly to perform rotational motion about the assembly axis , while simultaneously moving axially toward or away from the hose clamping assembly, thereby achieving synchronized axial advancement of the connector during rotation. This rotation +linear feed compound motion significantly reduces assembly time and is particularly suitable for precision-demanding rapid assembly applications.

A pipe mounting device includes an elongate part and a mounting head attached to a first end of the elongate part. The mounting head is sized and configured for positioning within a pipe end. The pipe mounting device is movable via the elongate part between a first position in which the mounting head is passable through an inner diameter of the pipe end along a length, and a second position in which the mounting head lockingly engages with the inner diameter of the pipe end and is usable to secure a position of the pipe end below a subfloor.

A pipe holding assembly includes a base and a screw extending upwardly from the base. A clamping unit is threadably attachable to the screw and the clamping unit is adjustable upwardly and downwardly on the screw. An extension pipe is insertable into the clamping unit such that the extension pipe is vertically oriented when the base is positioned on the support surface. Additionally, the extension pipe includes a coupling element. A cradle is movably attachable to a coupling element of the extension pipe such that the cradle has an adjustable height with respect to the extension pipe. In this way the cradle can be positioned to support a pipe.

A sanitary clamp device is disclosed and includes two half-ring components, a locking component and a cylindrical handle. The two half-ring components are connected through an adapter component and allowed to rotate around the adapter component so that locked ends of the two half-ring components engage with each other to releasably connect two sanitary fittings therebetween. The locking component is spatially corresponding to the locked ends of the two half-ring components. The locking end of the locking component is connected to the locked ends of the two half-ring components. The operating end is cooperated with a rotating locking component to lock or unlock the two half-ring components through the locking ends. The cylindrical handle runs through the operating end of the locking component. The cylindrical handle allows sliding relative to the operating end to adjust a force-arm length defined from one end of the cylindrical handle to the operating end.

A method of manufacturing a cylindrical cargo container includes: providing a plurality of rigid panels together formable into a cylindrical shell; forming a first semi-cylindrical shell from a first set of the panels; forming a second semi-cylindrical shell from a second set of the panels; forming the cylindrical shell from the first semi-cylindrical shell and the second semi-cylindrical shell; forming a collar conformably encircling the cylindrical shell; constricting the collar to compress joints formed at abutting edges of pairs of adjacent panels; rolling the cylindrical shell and collar to bring respective joints of pairs of panels to a lower position, and welding an inside seam of the joint when at the lower position; removing the collar from the cylindrical shell; and rolling the cylindrical shell to bring respective joints of pairs of panels to an upper position, and welding an outside of the joint when at the upper position.

A clamp jig includes: a fixed clamp having a fixed holding groove into which a part in a circumferential direction of a pipe is fitted; a movable clamp having a movable holding groove into which another part in the circumferential direction of the pipe is fitted to sandwich the pipe between the fixed holding groove and the movable holding groove, the movable clamp being provided so as to be movable with respect to the fixed clamp; and a tightening mechanism configured to pull the movable clamp toward the fixed clamp such that a bottom portion of the movable holding groove presses the pipe radially inward, in a state where the pipe is sandwiched between the fixed holding groove and the movable holding groove.
