A sprinkler system for salt water environments, comprising: a fluid inlet; a first and second nozzle branch each comprising a nozzle, and a fluid delivery line extending from the fluid inlet to the nozzle branches. A fluid delivery line filter is surprisingly provided outwith the fluid delivery line, on a further branch, to remove debris from the main delivery line extending to the nozzles. The fluid delivery line filter is provided in a housing, the internal diameter of the housing normally being larger than the internal diameter of the first and second nozzle branches, to facilitate the accumulation of debris. A fluid outlet is provided downstream of the fluid delivery line filter. The fluid outlet draws debris outwith the main delivery line and away from the nozzle branches, mitigating the possibility of nozzles being blocked. Fewer or less inline filters may be used in the main delivery line, thus mitigating problems associated with such inline filters blocking. Certain embodiments may be provided at the intake end, comprising a branch and filter system with an exit to atmosphere, also drawing debris away from downstream nozzle branches.
A debris management device for a sprinkler system, the debris management device comprising: a housing having an inlet and an outlet;a filter in the housing, wherein fluid flow between the inlet and the outlet of the housing must pass through the filter, the filter having a plurality of inlets therein;and a fluid flow control device downstream of the filter;wherein the fluid flow control device is adjustable to control fluid flow downstream of the filter. In use the device can be used to vent a controllable amount of fluid to the atmosphere. The present inventor has discovered that maintaining such a flow to atmosphere encourages flow of debris towards the device, away from a network of sprinklers in the sprinkler system, thus at least mitigating problems with the sprinklers blocking.
A pipeline apparatus comprising a reducing bush apparatus having a reducing bush, and a pipe fitting comprising a threaded socket. The reducing bush has an outer surface which comprises a threaded portion connected to the threaded socket of the pipe fitting. The reducing bush comprises a bore extending from a first end to a second end, the bore having an inner surface. The inner surface comprises a first threaded portion at its first end on an inside of the pipe fitting, and a second threaded portion at its second end on an outside of the pipe fitting. The outer surface has a larger diameter than the second end of the inner surface. Embodiments further include both a filter and nozzle threadably engaged, on opposite sides of the reducing bush.
A nozzle apparatus comprising a nozzle and a cap. The nozzle has a tube extending from a first end to a second end. The tube has a bore with an internal cross-sectional area. There is an inlet to the tube;and an outlet from the tube, the outlet having an outlet cross-sectional area. The nozzle has a plurality of further inlets in the tube between an outside thereof and the bore. The cap comprises an attachment means for attachment to the inlet to the tube, and comprises a cap inlet.
The present invention discloses a filter comprising a tube extending from a first end to a second end and having a bore with an internal cross-sectional area. The tube comprises an inlet with an inlet cross-sectional area which is positioned through the first end of the tube. The tube also comprises an outlet with an outlet cross-sectional area, wherein the inlet cross-sectional area is less than the outlet cross-sectional area and so debris small enough to enter the inlet will tend not to block the outlet, which is larger. The filter further comprises a plurality of further inlets, often slots, in the tube between an outside thereof and the bore. In a preferred embodiment, the first end may be tapered and especially dome shaped. This helps to direct debris towards an outside of the tube, where it is less likely to be drawn into the filter and potentially block it or a downstream component, such as a nozzle. The filter may be attached to a pipeline and a nozzle.
A nozzle apparatus comprising: an inlet, an outlet, a filter disposed between the inlet and the outlet, and, a container; wherein the nozzle apparatus defines a first flow path for particles too large for said filter and a second flow path towards the outlet for particles small enough for said filter; and wherein the container is provided downstream of the first flow path. In this way the pressure on the container downstream of the first fluid path causes the debris to accumulate therein and the nozzle is less liable to blockages. The apparatus is of particular use as a sprinkler system.

A method of providing a deluge system (10) on a boom (12) such as a boom that is used to conduct well flaring operations at an end thereof. The deluge system comprises a base unit (30), a stanchion (20), and a nozzle apparatus (22); the method comprising attaching the deluge system to a burner boom with a walkway, such that there remains a width of at least 30cm clear passage on the boom's walkway after the deluge system has been attached. This provides an escape and/or rescue route for personnel should a dangerous situation occur, such as uncontrolled fire or personnel falling overboard. In preferred embodiments, the deluge system is attached to the boom outboard of handrail supports (which includes on a single handrail). The deluge system may have its own mechanism e.g. a winch, for moving the stanchion from a stowed position to an operative position which allows a safe and more optimum positioning of the stanchion away from the well flaring operation, as herein described. In a preferred embodiment, the stanchion is provided as part of a moveable member which is rotationally attached to a connection mechanism of the base unit at a connection point spaced away from an end of the moveable member. This allows the moveable member to have a counter weight system and reduces the amount of force required to move the moveable member, avoiding mechanical constraints.
A nozzle apparatus (10) comprising: an inlet, an outlet, a filter (20) disposed between the inlet and the outlet, and, a container (40); wherein the nozzle apparatus defines a first flow path for particles too large for said filter and a second flow path towards the outlet for particles small enough for said filter; and wherein the container (40) is provided downstream of the first flow path. In this way the pressure on the container downstream of the first fluid path causes the debris to accumulate therein and the nozzle is less liable to blockages. To facilitate this, the size of the inlet may be the same size or bigger than the size of the flow path between the screen and the container. The container is normally removable and reattachable e.g. from the filter to remove debris. The filter may also comprise apertures and these may be of a size equal to or smaller than the outlet of the nozzle apparatus downstream of the second flow path. In this way, the outlet is less liable to being blocked by debris which is can pass through the aperture(s) in the filter. The apparatus is of particular use as a sprinkler system.
A nozzle system comprising a nozzle apparatus (610) and a pipeline (614), the nozzle apparatus attached to the pipeline such that there is fluid communication therebetween, the nozzle apparatus having a first inlet (631), a second inlet (622) and an outlet, wherein the nozzle apparatus extends into the pipeline such that at least a portion of the first inlet (631) is in the centre of the pipeline, that is within 15% of the central axis of the pipeline; and the second inlet (622) is within the pipeline but outwith the centre of the pipeline, the second inlet comprising a filter with at least one, normally at least four, linear apertures (625) therein, often parallel to a main axis of the nozzle apparatus (610). Preferably the first inlet is a larger aperture than the second inlet, and is provided on an end of the nozzle apparatus and the second inlet is provided on a side of the nozzle apparatus. An advantage of certain embodiments of the invention is that where debris builds upon an inside face of the pipeline (concentric corrosion), fluid can still flow through the inlet provided in the centre of the pipeline, and so nozzle apparatus as described herein are less liable to blockages.
