Abstract:
An internally coated pipe (10) for CNG distribution or delivery is disclosed, wherein the pipe is made of a thermosetting plastic material (3), and the internal coating is made of a metallic material (5). The thermosetting material (3) provides the required strength for the pipe (10), for handling the pressures to which the pipe will be exposed, e.g. up to 100 bar, whereas the metallic layer (5) provides the required impermeability to the component parts of the CNG.
Abstract:
A method for electroless metal deposition on a surface in a finely dimensioned space (e.g. the bore of a hollow fibre) comprises introducing into said space an electroless plating solution that has a nil or relatively low plating rate at normal room temperature, and there after heating said structure to an elevated temperature for a period sufficient to cause metal to plate on the wall surface. The steps of introducing and heating may be repeated as necessary to build up a required thickness.
Abstract:
A method of reducing magnetite formation in the bore of a pipe including the steps of selecting a pipe with a pre-existing oxide layer on its inner bore surface and coating the pre-existing oxide layer with an oxidation resistant metal to thereby reduce magnetite formation in the bore of the pipe.
Abstract:
Tubular needles have a reduced inner diameter tip portion (12) that increases back pressure behind the tip portion (11). This constricted tip portion promotes improved atomization, particularly when the liquid passes through the needle at near-supercritical conditions. A preferred method for constricting the inner diameter of a needle tip is to dip the tip of the needle in an electroless plating solution, such as an electroless nickel solution.

Abstract:
The invention relates to a method for surface coating of apparatuses or parts of apparatuses used in chemical manufacturing. Walls of apparatuses, walls of containers and walls of reactors, dischargers, fixtures, pumps, filters, compressors, centrifuges, columns, dryers, comminuting machines, internal fittings and combinations are examples for said apparatuses or parts of apparatuses. The inventive method is characterised in that a metal layer or a metal polymer dispersion layer is currentlessly deposited on the apparatus/es or parts of apparatuses to be coated by contacting the parts to a metal electrolytic solution which contains a reduction means and optionally the dispersed polymer or polymer mixture in addition to the metal electrolyte, whereby at least one polymer is halogenated.
Abstract:
A composite structural component is disclosed. The composite structural component can include a lattice structure, a casing disposed about at least a portion of the lattice structure, and a skin adhered to a surface of the casing. The lattice structure and the casing can be formed of a polymeric material and the skin can be formed of a metallic material.
Abstract:
A method of treating a surface includes the steps of providing a plating including at least some nickel over a nickel alloy surface in a thickness less than 0.0005" (0.001 cm), and exposing the surface to a fluoride ion cleaning to remove impurities on the surface, and leaving at least some of the plating.
