Apparatus for delivering material to a pipe

1. Apparatus for delivering material to a pipe, the apparatus including: an inlet configured, in use, to receive a fluid flow; an outlet configured, in use, to deliver the fluid flow to the pipe; an instrument receiving location for, in use, receiving at least part of an instrument, and a rotatable access arrangement for, in use, selectively providing or preventing access to the instrument receiving location, comprising: a first rotatable member rotatable between a first position in which the member provides flow communication between the inlet and the outlet via the instrument receiving location, and a second position in which the member does not provide flow communication between the inlet and the outlet via the instrument receiving location, and a second rotatable member rotatable between a first position in which the member provides flow communication between the inlet and the outlet, and a second position in which the member does not provide flow communication between the inlet and the outlet, wherein the inlet and/or the instrument receiving location is configured, in use, to be connected to at least one elongate flexible conduit, and where, in use, the instrument provides at least one material to be mixed with the fluid flow prior to delivery to the pipe via the outlet.

2. Apparatus according to claim 1 , further including a housing including an access aperture, wherein the access arrangement is configurable, in use, to provide access to the instrument receiving location via the access aperture.

3. Apparatus according to claim 2 , wherein the access arrangement selectively diverts the fluid flow from the inlet to either:

1) the instrument receiving location prior to passing the fluid flow to the outlet, or

2) the outlet without the fluid flow passing through the instrument receiving location.

4. Apparatus according to claim 2 , further including a handle for operating the access arrangement.

5. Apparatus according to claim 4 , wherein the access arrangement includes a spindle connected to the first rotatable member.

6. Apparatus according to claim 5 , wherein the spindle passes through the housing and wherein the spindle is hollow and function as a conduit for, in use, passing at least part of the instrument into the instrument receiving location.

7. Apparatus according to claim 1 , wherein the instrument comprises a spray head of an injection system configured to provide at least one pipe lining material.

8. Apparatus according to claim 7 , where, when the rotatable arrangement is diverting the fluid flow to the instrument receiving location, the fluid flow is mixed with the at least one pipe lining material prior to passing to the outlet.

9. Apparatus according to claim 7 , where, when the first rotatable member is in its first position, the second rotatable member is in its second position.

10. Apparatus according to claim 7 , wherein the first (and/or the second) rotatable member has a rounded outer surface and the flow communication provided by the first (and/or the second) rotatable member is provided via a bore through the first (and/or the second) rotatable member.

11. Apparatus according to claim 10 , wherein the flow communication provided by the first and the second rotatable members is provided via respective bores, wherein a first one of the bores is oriented in a direction perpendicular to a direction of a second one of the bores.

12. Apparatus according to claim 7 , further including a branch conduit leading from the inlet to the instrument receiving location.

13. Apparatus according to claim 7 , further including a connecting conduit leading from the inlet, via the second rotatable member to the outlet.

14. Apparatus according to claim 1 , wherein the access arrangement is configurable to provide access to the instrument receiving location whilst simultaneously allowing the fluid flow to flow from the inlet to the outlet.

15. Apparatus according to claim 1 , further comprising an elongate flexible conduit configured to provide the fluid flow to the inlet, and where, in use, the flexible conduit provides the fluid flow independently of part of the pipe system being processed.

16. A method of delivering material into a pipe, the method including:

providing apparatus according to claim 1 ;

connecting the apparatus to the pipe, and

using the apparatus to deliver material into the pipe.

17. Apparatus according to claim 1 , further comprising:

a housing including an access aperture for the instrument receiving location,

wherein the arrangement is configured for, in use, selectively providing or preventing access to the at least part of the instrument within the instrument receiving location via the access aperture.
