  • Publication number: 20120145276
    Abstract: A pipeline comprising an outer steel pipe and an internal corrosion resistant covering adhesively joined to the inside of the steel pipe. The pipeline can be taken up onto a drum and later unwound and laid out without any observed deformation of the metal covering. A method for the manufacturing of the pipeline comprises the steps of applying an adhesive onto the outside of the metal covering and optionally also onto the inside of the steel pipe, inserting the metal covering into the pipe and expanding the covering until being in a good contact with the inside of the steel pipe, and curing the adhesive to make the metal covering adhere tightly to the inside of the steel pipe.

  • Patent number: 8028711
    Abstract: A hot tap clamp. The clamp includes a first clamp part, a second clamp part, a fastener for stable fastening of the clamp parts around a section of a pipeline provided with a hot tap coupling, a pipe socket fixedly integrated with one of the clamp parts at an inner end and extending outward from the clamp part to an outer end, a hub on the outer end of the pipe socket, the pipe socket at the inner end going through the clamp part abutting the surface of the pipeline, such that the pipe socket can be sealingly welded to the pipeline by internal welding.
