  • Patent number: 10663091
    Abstract: A pipe system for oil country tubular goods (OCTG) and a method of manufacturing the OCTG pipe system is disclosed. The pipe system includes at least one OCTG pipe having a pipe body, the pipe body having at least one connection end formed in unipartite and materially integral manner with the pipe body for coupling to a second OCTG pipe. The OCTG pipe is formed in seamless fashion from a hardenable steel alloy, and the connection end has a yield strength higher than the yield strength of the pipe body.

  • Patent number: 9925701
    Abstract: A device for the application of foaming reaction mixtures to a substrate which makes it possible to apply that foaming reaction mixture uniformly, a process for the production of foaming reaction mixtures using this device, apparatus for producing composites which include the device of the present invention and composites produced using such apparatus are disclosed. Use of the device of the present invention to produce foams makes it possible to produce foams having improved surface quality at higher production rates than were previously possible. The device of the present invention is particularly useful for the production of sandwich composite elements.
