  • Publication number: 20220062967
    Abstract: A method for producing a tube (101-104), the method comprising: providing a preform (1a-c, 70) in a mandrel (2), the preform (1a-1c, 70) having two ends; flow forming the preform (1a-c, 70) with a plurality of rollers (4-5,31-38) such that in one flow forming pass neither one of the two ends of the preform (1a-1c, 70) is flow formed, thereby producing the tube (101-104); and mechanically forming mechanical connection ends on the two ends of the tube (101-104). Also, a seamless tube (101-104), a pipeline comprising a plurality of seamless tubes (101-04), and a machine for flow forming a preform (1a-1c, 70) into a tube (101-104).

  • Patent number: 10774411
    Abstract: A method for producing a tube of a nickel-based alloy tube which comprises the steps of hot working a nicked-based alloy casting into a pretubular-shaped workpiece or into a cylindrical bar, trepanning the cylindrical bar or machining an inner diameter of the pretubular-shaped workpiece to obtain a tubular workpiece, and cold working the tubular workpiece. The hot working comprises one of: rolling, forging, and a combination thereof. The cold working comprises flow forming or pilgering. A nickel-based alloy tube produced with the method comprises an outer diameter greater than or equal to 60.3 mm, an average wall thickness greater than or equal to 2.8 mm, and less than or equal to 70 mm.

  • Patent number: 9378880
    Abstract: Methods are disclosed for synthesizing nanocomposite materials including ferromagnetic nanoparticles with polymer shells formed by controlled surface polymerization. The polymer shells prevent the nanoparticles from forming agglomerates and preserve the size dispersion of the nanoparticles. The nanocomposite particles can be further networked in suitable polymer hosts to tune mechanical, optical, and thermal properties of the final composite polymer system. An exemplary method includes forming a polymer shell on a nanoparticle surface by adding molecules of at least one monomer and optionally of at least one tethering agent to the nanoparticles, and then exposing to electromagnetic radiation at a wavelength selected to induce bonding between the nanoparticle and the molecules, to form a polymer shell bonded to the particle and optionally to a polymer host matrix. The nanocomposite materials can be used in various magneto-optic applications.
