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 piping structure and a process, with which it is possible to form an opening in a pipe while preventing shavings produced from cutting from entering the pipe. A process for forming an opening in a pipe, including: a step of enclosing the pipe with a case divided in a circumferential direction R of the pipe; a skin formation step of cutting an outer surface of the pipe with a cutting tool arranged in the case, thereby forming a bottomed groove, which is formed as a skin, on the pipe; a suction step of sucking shavings produced from cutting, together with a gas in the case in order to remove the shavings; and breaking the skin to form the opening after performing the skin formation step and the suction step.

A fitting for connecting a branch conduit to a liner installed in a main pipe is configured to mechanically connect to the branch conduit as it is inserted into the branch conduit from inside the main pipe. The mechanical connection is established without rotating the fitting. The fitting can include a body having an outer shaft section for being received in the branch conduit and an inner flange section for opposing the liner within the main pipe. The fastener include one or more teeth that extend radially from the exterior of the shaft section. The teeth can be secured to the shaft section by deforming portions of the fitting body against the teeth. The flange section supports a gasket for sealing against the liner when the fitting is installed. The flange section can include a rim that maintains the gasket in the proper position.

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 tapping sleeve for a pipe element can include first and second sleeve portions, each defining a first axial end, a second axial end, a first side end, a second side end, and an arcuate portion extending between the first side end and the second side end; the second sleeve portion hingedly secured to the first sleeve portion; and a connecting element joining the first side ends of the first and second sleeve portions; wherein the connecting element, the first side end of the first sleeve portion, and the first side end of the second sleeve portion define at least a portion of a hinge of the tapping sleeve, a position of the first sleeve portion with respect to the second sleeve portion in an assembled condition in a circumferential direction of the tapping sleeve being different between the at least two assembled conditions of the hinge.

A clamp and spike combination for use in conjunction with a flexible conduit, comprising a spike including an inlet rod with a sharpened tip for penetration into the conduit, an outlet rod connected to the inlet rod, the outlet rod having a barbed tip for attachment to a tube. The bore extends through the rods from the sharpened tip to the barbed tip, whereby the spike provides a channel for the passage of fluid. Further included, a clamp including two legs extending substantially parallel with each other and spaced apart from each other by a distance, an apex portion connecting the two legs to each other so that the clamp is shaped substantially in the form of an inverted U; and an opening in the apex portion, the opening being sized to receive the inlet rod of the spike.

The invention relates to the field of operations of cutting and isolating pipes that may contain a product that is hazardous to the environment or the personnel carrying out work and requires leak tight handling. The invention relates more particularly to a containment device 1 for work carried out on a pipe comprising a rigid tool flange 11 having an end wall provided with an orifice with a section adapted to the external cross of the pipe, an opening wider than the orifice located opposite the end wall, and a side access 111 for a cutting tool, and a flexible film 13 for forming a leak tight volume around the pipe, wherein a first film end that is fixed to the opening in teh tool flange mounted on the pipe and a second film end that is connected to the pipe. The invention also relates to a method for cutting and isolating a pipe.
