摘要:
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.
摘要:
A method for forming a connection between two tubular sections having a polymeric outer surface jacket, using electrofusion to fusion bond a casing of similar, non-crosslinked polymer to the outer surface of the tubular sections.
摘要:
An automated heat shrink device, useful for forming a connection between two tubular sections having a polymeric outer surface jacket, for example, a connection between two sections of a district heating pipeline, and a method of use thereof. The device is configured such that it requires minimal clearance to either side of the pipeline when being used.

摘要:
A pipe coating finishing device is made up of a frame having a first arm and a second arm. A scraper is coupled to a first arm pipe end of the first arm for engaging a pipe to remove material in excess of a maximum pipe diameter. In addition, a vibrating plate is coupled to a second arm pipe end of the second arm for compacting an impinged concrete coating on the pipe. Also disclosed is a process for finishing an impinged concrete coating on a pipe with a device, as disclosed herein.

Disclosed herewith is an ultraviolet-crosslinked article comprised of a polymer composition, wherein the article is crosslinked by exposure to ultraviolet radiation and possesses a degree of crosslinking such that it is softened but does not become liquid.
摘要:
A photo-crosslinkable polyolefin composition comprises a polyolefin, a source of functionality receptive to crosslinking by UV radiation, a cationic photoinitiator and optionally includes a free-radical photoinitiator, a crosslinking accelerator or sensitizer, and other additives such as compatibilizers, inorganic fillers, nanofillers, glass, polymeric and ceramic microspheres, glass fibres, flame retardants, antioxidants, stabilizers, processing aids, foaming agents and pigments. A method for manufacturing a UV-crosslinked polyolefin article comprises forming an article by extruding, moulding or otherwise forming the UV-crosslinkable polyolefin composition and subjecting the article to UV radiation on-line with the extrusion, moulding or other forming operation.
