Abstract

A perforating device capable of perforating a process for perforating a fluid duct having a connector seat with a tapped barrel. The device generally includes a hollow cylindrical body, a cutting apparatus, a fluid passage and a valve. The cylindrical body has an internal volume, a longitudinal axis, a first open end, a second end opposite the first, and a threaded external surface. The cylindrical body can be threadingly received or retracted within the barrel such that the cylindrical body moves along the barrel toward or away from the fluid duct. The cutting apparatus is operably coupled to an end of the cylindrical body and is adapted to cut the duct by screwing the body into the barrel. The valve seals the internal volume of the cylindrical body in response to a differential pressure between the interior of the duct and the ambient atmosphere to prevent leakage from the duct.

Abstract

The method of automatic optimization is applied to a natural gas transport network in the steady state comprising at one and the same time a set of passive works such as pipelines or resistances, and a set of active works comprising regulating valves, isolating valves, compression stations, storage or supply devices, consumption devices, elements for bypassing the compression stations and elements for bypassing the regulating valves, the passive works and the active works being linked together by junctions. The optimization method comprises the determination of values for continuous variables. Intervals of values for the continuous variables and sets of values for the discrete variables are chosen as initial state of the optimization. The possibilities of values for the variables are explored by constructing on the go a tree with branches linked to nodes describing the combinations of values envisaged by using a separation of variables and evaluation technique, the values of the quantities sought being considered to be optimal when predetermined constraints are no longer violated or are minimally violated and a predetermined objective function is minimized.

Abstract

The invention relates to a flow control device which is insertable into a fluid pipeline (K) and comprising a valve (1), an obturator with membrane (2), and anchoring flaps (3) that can deploy like umbrella spokes under the action of an elastic stress until it presses against the wall (P) of the pipeline (K). According to the invention, the membrane (2) and the flaps (3) are mutually attached to and disposed on a same side of the valve body (10), so that as the flaps (3) deploy the membrane (2) deploys at the same time until the membrane presses against the internal wall of the pipeline (K) and the fluid exerts on the deployed membrane a pressure which increases the pressure of the flaps (3) against this wall (P).
