Abstract

A tubular system made up of a tubular (10), a liner (12) in the tubular (10), and longitudinally oriented members (15, 16, and 17), which may be disposed within the channels in the liner. The members advantageously may be used for pulling a liner into a host tubular, and/or maintaining the structural strength of the liner (12). The members are continuous along the length of the plastic-lined tubular (10), and if applicable, through intermediary joints. The channels may be in the inner and/or outer surfaces of the liner (12). The members may be usable for carrying electrical current or signals, fiberoptic signals, or data communications; for heating the liner; and/or for detecting faults in the liner and/or the host tubular (10).

Claims

AMENDED CLAIMS
[received by the International Bureau on 12 June 2000 (12.06.00); original claim 11 amended; new claims 36-45 added; through said member, remaining claims unchanged (3 pages)]
9. The method of claim 6, wherein said heat is applied by radiation from the exterior of said liner.
10. The method of claim 4, wherein said adhering step comprises the step of applying an adhesive between said member and said liner.
11. The method of claim 4, wherein said member is disposed in a channel which is formed in said outer surface of said liner, and wherein said adhering step comprises the steps of disposing said member in said channel, then radially compressing the liner so that said channel grips said member.
12. The method of claim 11. wherein said member comprises a cable.
13. The method of claim 11 , wherein said member comprises a generally helical spring.
14. The method of claim 13, wherein said spring has a spring constant which is suffer than a modulus of elasticity of said liner so that said liner is pulled by said member into said tubular without placing substantial additional strain on said liner.
15. The method ofclaim 11 , wherein said memberwheπ in said channel is disposed fully inside said outer surface of said liner.
16. The method of claim 15, wherein said member is adhered to said liner sufficiently to remain in said channel.
17. The method of claim 11 , wherein said member is adhered to said liner sufficiently to remain in said channel.
18. The method of claim 11 , further comprising the step of making said member of a sufficiently strong matbrial to resist deformation of said channel due to increased pressure in said liner bore.
19. The rriethod of claim 11 , further comprising the step of making said member of a sufficiently strong material to resist deformation of said channel due to thermal softening of said
AMENDED SHEET (ARTICLE 19 20
34. The method of claim 31 , wherein said tubular system is assembled by the steps of: placing a predetermined initial stress on said liner so as to induce a strain; then adhering said liner to at least one elongated member; and then pulling on said member, so that said liner is pulled, along with said member, into said tubular without inducing substantial additional strain on said liner.
35. A method of assembling a tubular system, the tubular system comprising a tubular; a liner in the tubular, the liner having an outer wall engaging an inner wall of the tubular, the liner having an inner wall defining a hollow bore; and at least one elongated mejmber which is disposed between said liner and said tubular and defines a fluid flow passage between said liner and said tubular, said method comprising the steps of: placing said liner and said member in contact with each other; while said liner and said member remain in contact, pulling said liner into said tubular.
36. The method o claim 35, wherein said contact between said elongated member and said liner protects said elongated member from deformation while being pulled into said tubular.
37. The method ofclaim 36, wherein said elongated member comprises a communications cable.
38. The method of claim 36, wherein said elongated member comprises a heating cable.
39. The method of claim 36, wherein said elongated member comprises a force-sensing cable.
40. The method of claim 36, wherein said elongated member comprises an efectrical or fluid-carrying conduit.
41. The method of claim 36, wherein said member is disposed in a channel which is formed in said outer surface of said liner, and wherein said adhering step comprises the steps of disposing said member in said channel, then compressing said channel so that said channel grips said elongated member.
42. The method of claim 41 , wherein said member and liner are pulled into said tubularwith said channel still compressed. 21
43. The method of claim 41 , wherein said channel is compressed by radially compressing said liner.
44. The method of claim 43, wherein said member and said liner are pulled into said tubular with said liner still compressed.
45. The method of claim 11 , wherein said member and said liner are pulled into said tubular with said liner still compressed.
