Abstract
device and method for delivering a fluid to a first conduit having an opening that communicates with a larger second conduit, the device having a tubular body defining a central axis and having a first opening at a first end and a second opening at a second end, the second end being at an angle to the central axis, wherein the second opening is associated with a seal member capable of creating a fluid seal such that fluid can be delivered to the first conduit, and wherein the seal member has an elongate body and a gasket each having a convex upper surface engageable with an inner surface of the second conduit. Problem solution; Adding a seal member with an elongate body between a device and a conduit to enable to operate under high pressure without stopping the operating process.
Claims (12)
1. A device for delivering a fluid and/or inspecting and/or accessing a first conduit having an opening that communicates with a larger second conduit, the device having a tubular body defining a central axis and having a first opening at a first end and a second opening at a second end, the second end being at an angle to the central axis, wherein the second opening is associated with a seal member capable of creating a fluid seal such that fluid can be delivered to the first conduit, characterised in that the seal member has an elongate body and a gasket each having a convex upper surface engageable with an inner surface of the second conduit.
2. The device as claimed in claim 1 wherein the seal member comprises a polygonally shaped body having a convex upper surface for contacting the inner face of the second conduit and which substantially conforms to the shape of the inner face of the second conduit.
3. The device as claimed in claim 1 or 2 wherein the seal member has a dimension that is at least a quarter of the length of the device.
4. The device as claimed in claim 1, 2 or 3 wherein the seal member has a cross section being a circular segment or semi elliptical.
5. The device as claimed in claim 1, 2, 3 or 4 wherein the device has means for urging the seal member against the inner face of the second conduit.
6. The device as claimed in claim 5 wherein the means for urging the seal member against the inner face of the second conduit comprises one or more displacement members. James & Wells Ref: 309455NZ
7. The device as claimed in claim 6 wherein the one or more displacement members comprise a telescopically extending leg; and /or wherein the one or more displacement members comprise a jack.
8. The device as claimed in any one of claims 6 or 7 wherein the one or more displacement members have a foot which is shaped to conform to the inner face of the second conduit.
9. The device as claimed in any one of the previous claims wherein the first and second conduits are pipes; and/or having at least one camera; and/or connectable to a fluid supply; and/or wherein the first and second openings permit the entry and/or exit of a pipe inspection gauge; and/or wherein the second opening at the second end is perpendicular to the central axis and the first opening at the first end.
10. A method of accessing a feeder tube extending at an angle from a header pipe, the method comprising: providing a device in accordance with any one or more of the previous claims; introducing the device into the header pipe; creating a pressure seal and mechanically coupling the device with the feeder tube; and James & Wells Ref: 309455NZ introducing or utilizing service methods, such as, but not restricted to: high pressure jet blasting lances, vacuum pressure, positive fluid pressure, fluid cleaning agents, mechanical decoking pigs, inspection pigs, or optical borescopes to the feeder tube through the device.
11. The method of claim 10, further comprising actuating a jack to press against the interior surface of the header pipe to create a pressure seal and mechanically couple the device with the feeder tube.
12. The method of claim 10 or 11 further comprising optically scanning the interior surface of the header pipe with a camera to align the feeder tube coupler with the feeder tube. 111 144 116 143 144
