Abstract: A multi layer pipe coating for steel pipe, and a method of production of same. The multi layer coated steel pipe has a first layer of coating, which is an anti-corrosion coating, a second layer of coating, comprising a thermoplastic selected from the group consisting of polyphenylene sulfide, polypropylene, and polystyrene, an epoxy intermediate layer between the second layer of coating and a third layer of coating, and a third layer of coating, which comprises a thermoplastic selected from the group consisting of polyphenylene sulfide, polypropylene and polystyrene. The second layer of coating and the third layer of coating comprise different thermoplastics.

Abstract: A method of coating a field joint, pipe sections for forming a coated field joint, and a coated field joint formed thereby. First and second angular cut backs are provided in the parent coating of each pipe section. The first angular cut back is at an angle of about 30°±5° relative to the longitudinal axis of the field joint, and the second angular cut back is positioned further from the field joint than the first angular cut back. The first and second angular cut backs result in the parent coating having a stepped profile, a step in the stepped profile between the first and second angular cut backs, the is substantially parallel to the longitudinal axis of the field joint and is free of indentations. The field joint coating is injection moulded to have an upstand that is less than or equal to about 5 mm.

Abstract: The present invention relates to coating compositions, processes for making them, and methods of application of the coating compositions. Further, the present invention relates to a process and apparatus for coating a metal substrate, for example an elongated metal tubular substrate such as a pipe. Most particularly, the coating can be used as an anti-corrosion coating on a pipe for use in oil, gas and water pipeline applications.

Abstract: A method of providing a foamed insulation coating on at least a portion of a pipe, including extruding a melt stream over the pipe portion. The melt stream includes a matrix polymer and expandable fillers in an unexpanded state, the melt stream being maintained at a sufficiently high temperature to maintain the matrix polymer in extrudable form and at a sufficiently high pressure to maintain the expandable fillers in the unexpanded state. Once extruded, the expandable fillers are permitted to expand into an expanded state at a lower pressure.
