A pipe boring device (1) including a housing (2)for receiving a self-tapping ferrule insert and a strap (3, 4) for securement around a pipe (10) to enable a hole to be bored into the pipe(10) by the ferrule insert. The strap (3, 4) includes first and second strap portions(3, 4) pivotally secured at a first of their ends (30, 40) by a connector (5). The first strap portion (3) includes a pair of slots (35a, 35b) along its length, which terminate at a second end (34) of the first strap portion (3) to form slot ends (36a, 36b). The second strap portion (4) includes three pairs of hooks (45a, 45b, 46a, 46b, 47a, 47b) along its length, which are receivable within the slots (35a, 35b) and configured to engage the slot ends (36a, 36b). The strap (3, 4) is configured to be wrapped around a pipe (10) with the first strap portion (3) overlapping the second strap portion (4) such that the second strap portion (4) is between the first strap portion (3) and the pipe (10) and one of the hook pairs (45a and 45b, 46a and 46b, 47a and 47b) is in engagement with the slot ends (36a, 36b). Each hook pair (45a and 45b, 46a and 46b, 47a and 47b) is spaced one from the next along the length of the second strap portion (4) such that the strap (3, 4) defines an opening for receiving the pipe (10) that is dependent upon which of the hook pairs (45a and 45b, 46a and 46b, 47a and 47b) is in engagement with the slot ends (36a, 36b).

The invention relates to a tapping fitting, having a saddle component for positioning on and cohesively connecting to a tubular component, and having a clamping device for clamping the saddle component on the tubular component, characterized in that the clamping device has a tiltable clamping lever with a sliding profile, wherein the clamping lever is mounted via the sliding profile in a bearing shell in a first peripheral portion of the saddle component, and wherein a clamping band is attached on one side to the clamping lever at a distance from a rotation axis about which the clamping lever is tiltable in the bearing shell, and on the other side to a second peripheral portion, located opposite the first peripheral portion, of the saddle component, such that in the case of a tapping fitting positioned on a tubular component, when the clamping lever is tilted, the clamping band is biased and the tapping fitting is pressed against the tubular component.

A tapping saddle for a plastic main pipe carrying a medium includes a stub having a central axis, a saddle piece, and a drill. The drill is configured to be moved axially in the stub. A heating element geometry, which is used for welding the tapping saddle to a main tube outer circumference, is arranged on an inside diameter of the saddle piece. The heating element geometry has a winding having an outer winding region and an inner winding region. In the inner winding region, the winding extends in meandering loops along a circle concentric with the central axis of the stub.

A pipe clamp for a main pipe conveying a medium. The pipe clamp includes a saddle member and bearing elements, wherein the bearing elements are arranged on the saddle member. The pipe clamp further includes a tension unit, wherein the tension unit comprises at least one band for encircling the main pipe, a band linkage, and a clamping lever. The band linkage and the clamping lever are each arranged at one end of the at least one band and are opposite one another. An extension is arranged on the clamping lever, and the extension is configured to be removed from the clamping lever after the tension unit is firmly clamped on the main pipe.

A pipe tapping saddle for a main pipe having a center axis and conveying a medium. The pipe tapping saddle includes a saddle piece; a branch pipe having a center axis, a drill socket having a center axis, and a drill with a thread being arranged displaceably in the drill socket for tapping the main pipe. The pipe tapping saddle is arranged on the main pipe. A center axis of the branch pipe runs horizontally and is arranged below an upper crown point of the main pipe.

A core sampling and tapping assembly is disclosed that may be mounted to a cylindrical pipe. The assembly includes a nozzle having an interior portion extending between an open distal end and a proximal end. The proximal end sealed to an upper saddle member and the upper saddle member coupled to a lower saddle member to clamp the pipe in between. The assembly further includes a tapping mandrel including a mandrel plate, the tapping mandrel extending through the interior portion and a core cutter fixedly coupled to the mandrel plate. The assembly further includes a pilot bit coupled to the mandrel plate and disposed within an interior cavity of the core cutter. The tapping mandrel adjacently aligns the core cutter and the pilot bit with an outer surface of the pipe and subsequently rotates the pilot bit and core cutter to collect a core sample from the pipe.

A fusible fitting of this disclosure includes a saddle having a radially extending branch with a closed bottom end. The closed bottom end forms a portion of the saddle and contains some of the fusion wires that run through the saddle. After the fitting is fused to a pipe, the closed bottom end may be tapped through, with that portion of the fusion wires being removed along with the coupon. Because of this configuration, the branch may be a size-on-size or near size-on-size branch. For example, the radially extending branch may have an inside diameter in a range of greater than 75% of an inside diameter of the pipe to 100% of the inside diameter of the pipe plus one wall thickness of the pipe.
