A method of cleaning a pipeline is performed by introducing a treatment composition comprising a colloidal particle dispersion having inorganic nanoparticles with an average particle size of from 500 nm or less into an interior of a pipeline to be cleaned. A pig or body is passed through the pipeline to spread the composition upon surfaces of the interior of the pipeline. The composition and materials adhering to the surfaces of the interior of the pipeline are removed to facilitate cleaning of the pipeline

The present invention relates to a new use of foaming products for the production of a compact foam pig, by means of the forced interaction of gas, water and product, capable of moving huge quantities of water accumulated in the gas production pipelines. The water removal takes place in very quick periods of time and allows an important decrease in the pressure drops with consequent quick increase in the produced gas quantities.

A cleaning installation of a heat exchanger includes a heat exchanger linked upstream to an intake duct for a fluid and downstream to an outlet duct for the fluid. A system is provided for recovering cleaning bodies from the outlet duct after cleaning of the exchanger by the bodies and for reinjecting bodies into the intake duct. The system includes a member capable of being displaced between a first position in which the system is configured to recover and contain cleaning bodies in the mobile member, and a second position in which the system is configured to take fluid from the intake duct and reinject, into this duct, via the mobile member and under the action of the fluid taken, cleaning bodies contained in the member.

A bypass valve for an inspection and/or cleaning pig which is intended to move through a pipeline through which medium flows. The bypass valve comprises an inner space which is provided with a flow profile and in which there is arranged a piston which can be moved in the longitudinal direction of the bypass valve by means of a force storage medium in a pressure-dependent manner. The piston can also be moved between a first open position of the bypass valve which enables a bypass for the medium and a second position which at least substantially closes the bypass. The piston can be further moved from the first position via the second position in the same direction into a maximum position which opens the bypass again and pig for inspection and/or cleaning of pipelines.

A hose clearing apparatus has a cylindrical body, a fluid coupler on the rear side, and a fluid nozzle on the front side. A method of clearing a hose involves coupling a fluid to the fluid coupler, adjusting the fluid nozzle to achieve the desired spray, powering on the vacuum with the hose coupled thereto, inserting the front of the body and accompanying nozzle into the hose, and allowing the hose to traverse through the hose.

The object of the invention is to provide a device which can, with high efficiency, polish and clean the inner surface of a pipe, dry the wet inner surface of the pipe, and perform coating, wherein the device does not require a large pump or a large motive force, and does not require a blast hose or a suction hose. More specifically, provided is an intra-pipe turbine blast system that moves along the inside of a pipe and performs work by spraying a fluid toward the inside of the pipe, wherein: a gas injected from a fluid supply device to the upstream-side end inside the pipe imparts speed to a mixed phase fluid consisting of a liquid and solid particles which are likewise injected into the pipe; the flow speed of the mixed phase fluid is set to 3 m per second which is the critical speed at which solid particles can float without precipitating in the liquid, and as a result of such setting, there is a great effect on reducing the energy required for causing the mixed phase fluid to move; and the mixed phase fluid with such setting is injected at a high speed from a rotation nozzle of a turbine crawler which moves inside the pipe, thereby polishing the inner surface of the pipe, and following the polishing work, the turbine crawler can clean, dry and coat the inner surface of the pipe.

The present invention relates to an intervention drive pig comprising an umbilical. In this scenario, the present invention provides an intervention drive pig comprising an umbilical, wherein the umbilical (6) is manufactured from a low-density material, wherein the umbilical (6) comprises an external covering of material having a low coefficient of friction.

Provided are techniques for operating a pipeline that include: determining, based on observed operational parameters of equipment of an upstream process facility, an indirect quality parameter for processed production fluid output from the process facility and routed into a pipeline; determining, based on characteristics of the processed production fluid output from the facility, a direct quality parameter for the processed fluid; determining a quality parameter for the processed fluid defined as the greater of the indirect and the direct quality parameter for the processed fluid; determining, based on the quality parameter for the processed fluid, a model of the pipeline that includes a cumulative water accumulation of a segment of the pipeline; determining, based on the cumulative water accumulation, a water remediation schedule for the segment; and conducting, in accordance with the schedule, a water remediation operation in the segment of the pipeline.
