Abstract
A pipe system comprises a plurality of pipe members (2), mechanical connections at the end regions of the pipe members whereby the pipe members can be connected together into end-to-end relationship to provide at least one fluid flow path along them, and electrical conductors (10; 110) carried by the pipe members, the electrical conductors having contact areas (19) exposed at the end regions of the pipe members so that electrical connection between the conductors of adjacent pipe members can be effected by bridging members (25) spanning the end regions of the pipe members.
Claims27
A pipe system comprising:
- two pipe members having interengageable connecting means by which said two pipe members are mechanically connected together in end-to-end relationship,
- electrical conductor means extending within each of said pipe members, and
- electrical connection means at the connected ends of said pipe members, establishing electrical connection between said electrical conductor means of the connected pipe members, wherein:
- said electrical connection means comprise external contacts exposed at the outer surfaces of said pipe members at the end regions thereof adjacent said interengageable connecting means,
- a bridging member extending across the mechanically connected ends of said pipe members and mounted externally of said pipe members, said bridging member being received in recesses at the end regions of said pipe members and forming a continuous outer surface with said pipe members, and
- second conductor means included in said bridging member, said second conductor means having second contacts exposed at positions on said bridging member adjacent said pipe members and in engagement with said external contacts exposed at the outer surfaces of said pipe members.

A pipe system comprising two pipe members,
- mechanical connection means effecting connection of said two pipe members together in end-to-end relationship,
- a plurality of electrical conductor means extending externally lengthwise of each of said pipe members,
- a contact portion of each conductor means externally exposed at each end region of the pipe member along which said conductor means extends,
- electrical bridging means electrically connecting each of said contact portions at the end region of the connected end of one of said pipe member with a respective contact portion at the end region of the connected end of the other pipe member, and
- a protective sleeve around said electrical bridging means.
2 more elements
A pipe system comprising:
- two pipe members having interengageable connecting means by which said two pipe members are mechanically connected together in end-to-end relationship,
- electrical conductor means extending within each of said pipe members, and
- electrical connection means at the connected ends of said pipe members establishing electrical connection between said electrical conductor means of the connected pipe members, wherein:
- said electrical connection means comprise external contacts exposed at the outer surfaces of said pipe members at the end regions thereof adjacent said interengageable connecting means,
- a bridging member extending across the mechanically connected ends of said pipe members and mounted externally of said pipe members, said bridging member comprising a sleeve surrounding said mechanically connected ends of said pipe members, said sleeve comprising axially split portions, and
- second conductor means included in said bridging member, said second conductor means having second contacts exposed at inner surface positions on said bridging member adjacent said pipe members and in engagement with said external contacts exposed at the outer surfaces of said pipe members.
3 more elements
A pipe system comprising two pipe members,
- mechanical connection means effecting connection of said two pipe members together in end-to-end relationship,
- a plurality of electrical conductor means extending externally lengthwise of each of said pipe members,
- protective means for said conductor means extending lengthwise of each of said pipe members externally of said conductor means, said protective means comprising a plurality of elongate members each extending externally of a respective conductor means, said elongate members having longitudinally extending edges at which said elongate members are welded to said pipe member,
- a contact portion of each conductor means externally exposed at each end region of the pipe member along which said conductor means extends, and
- electrical bridging means electrically connecting each of said contact portions at the end region of the connected end of one of said pipe member with a respective contact portion at the end region of the connected end of the other pipe member.
2 more elements
In a pipe system comprising first and second pipe members in end-to-end relationship:
- first and second connecting means formed at the adjacent end regions of said first and second pipe members respectively, said first and second connecting means being interengaged to establish a direct rigid mechanical connection between said first and second pipe members,
- a bridging member located outwardly around said adjacent end regions of said first and second pipe members, and
- a plurality of electrically conductive paths extending along said first and second pipe members, each said path comprising a first conductor extending along said first pipe member to a contact exposed at the outer surface of said first pipe member at said end region thereof, a second conductor extending along said second pipe member to a contact exposed at the outer surface of said second pipe member at said end region thereof, and a third conductor in said bridging member and having contacts electrically contacting said contacts of said first and second conductors.
