Systems and methods are disclosed for protecting a tether line within a pressurized pipe. As the tether line is extended and retracted, portions of the tether line are prevented from directly engaging jagged profiles formed in the pressurized pipe.

The present invention proposes a split clamp (7), typical of trepanning operations in pipes, which allows the intervention with a tool (3) that makes a circular hole in the pipe (1) under analysis, removing layer by layer, until reaching the pressure barrier (2). With this, a sample of the layer of interest is removed to be forwarded for analysis. Such a clamp (7) has means to isolate the pipe (1) from the external environment, introduce the tool (3) and remove the same with the sample, also allowing tightness repair of the pipe (1).

The invention relates to a pipe clamp, in particular an electric welding pipe clamp which can be mounted around a plastics pipeline, containing a saddle element having a connecting piece for a tapping unit or for the connection of an outgoing pipeline, straps to wrap around the pipeline, strap ends, wherein the strap ends have latching means, at least one latching area, wherein the strap ends are latched in in the latching area in order to fix the pipe clamp to the plastics pipeline, wherein the latching area has a tensioning element, wherein the tensioning element is arranged such that the tensioning element can be slid into a tensioning element groove.

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.

Embodiments of a polyethylene (“PE”) pipe servicing system of this disclosure may include a fusible PE fitting (F) providing a branch connection to a PE pipeline section or run (P), a valve (10) connected to the fitting and including quick connect/disconnect means, and a machine connectable to the valve including complementary quick connect/disconnect means. The quick connect means provide for full scope of operation, including cleaning, fusion, cool down, hot tap, plugging, and completion. No squeezing is used. The quick connect/disconnect means may include a first portion 20 of a cam profile and a second portion 40 of the cam profile complementary to that of the first. The machine may be a drilling or hot tapping machine (30T), a plugging machine (30P), or a completion machine (30C), and their associated tools. The valve and machine are more lightweight and faster and easier to use than the prior art.
