Fluid conduit assembly

A fluid conduit assembly comprising:

• first and second fluid conduits;
• a coupling including first and second coupling sections, each coupling section defining a respective hollow bore along which flowable material may flow, the first coupling section in fluid connection with the first fluid conduit, the second coupling section in fluid connection with the second fluid conduit, the coupling sections configured to be releasably coupled to each other;
• and
• at least one shut-off valve located within the hollow bore of at least one of the coupling sections, the or each shut-off valve including a valve member movable between a valve open position and a valve closed position in which the valve member shuts off the flo (/=w of a flowable material through the hollow bore, the or each valve member configured to move to its valve closed position on separation of the coupling sections,
• wherein the first coupling section is connected to the first fluid conduit so that a first end of the first coupling section extends inside a hollow bore of the first fluid conduit along which flowable material may flow and a second end of the first coupling section is located outside the hollow bore of the first fluid conduit, and/or wherein the second coupling section is connected to the second fluid conduit so that a first end of the second coupling section extends inside a hollow bore of the second fluid conduit along which flowable material may flow and a second end of the second coupling section is located outside the hollow bore of the second fluid conduit,
• wherein the or each first end has a tapered bore profile that tapers from an interior surface of the hollow bore of the first and/or second fluid conduit along which flowable material may flow in a direction towards the corresponding second end,
• wherein the tapered bore profile defines a section of a hollow bore of the corresponding first end that is furthest inside the hollow bore of the corresponding fluid conduit;
• and
• wherein the or each second end of the first coupling section and/or second coupling section includes a flange to be secured to a flange of the corresponding fluid conduit to secure the first coupling section and/or second coupling section to the corresponding fluid conduit and support the corresponding first end to extend in the corresponding fluid conduit.
