Abstract
A spinner apparatus for applying lining material to the interior of a pipe, the spinner apparatus having a cylindrical material accelerator coaxially positioned about a distribution manifold, the distribution manifold having a plurality of equally spaced, radially oriented slots extending from an axial chamber that receives lining material, wherein lining material is extruded through the slots onto the interior of the material accelerator and slung onto the pipe interior in an annular pattern. Movement of the spinner apparatus along the pipe produces a tubular lining member.
Claims20
A spinner assembly adapted to expel lining material onto the interior surface of a tubular member, said spinner assembly comprising:
- a rotating material accelerator comprising a tubular body having a plurality of apertures distributed circumferentially and axially on said tubular body;
- a static distribution manifold disposed coaxially and concentrically within said rotating material accelerator, said static distribution manifold comprising a central axis, an inlet port disposed within a proximal tubular end, an axial chamber in communication with said inlet port;
- a plurality of radially extending slots in communication with said axial chamber and comprising slot openings, said plurality of radially extending slots being equally spaced circumferentially and adapted to extrude lining material through said slot openings onto the interior of said rotating material accelerator, said plurality of radially extending slots extending radially outward from said axial chamber such that said slot openings are disposed beyond said proximal tubular end in the radial direction;
- and
- wherein said static distribution manifold is disposed within said rotating material accelerator such that the axial distribution of said plurality of apertures of said tubular body of said rotating material accelerator is such that said plurality of apertures is axially coextensive with and positioned radially outward from said slot openings.
A spinner assembly adapted to expel lining material onto the interior surface of a tubular member, said spinner assembly comprising:
- a rotating material accelerator comprising a tubular body having a plurality of apertures distributed circumferentially and axially on said tubular body;
- a static distribution manifold disposed coaxially and concentrically within said rotating material accelerator, said static distribution manifold comprising a plurality of radially extending slots, said plurality of radially extending slots being equally spaced circumferentially and adapted to extrude lining material onto the interior of said rotating material accelerator;
- said static distribution manifold further comprising a central axis and slot openings, and wherein each of said slot openings comprise a maximum longitudinal linear dimension and wherein said maximum longitudinal linear dimension of each of said slot openings is aligned substantially parallel to said central axis;
- said static distribution manifold further comprising an inlet port disposed within a proximal tubular end, an axial chamber in communication with said plurality of radially extending slots and an inlet port in communication with said axial chamber, said inlet port adapted to receive lining material;
- said slot openings each having a cross-sectional area and said inlet port having a minimum cross-sectional area, wherein the minimum cross-sectional area of said inlet port is substantially equal to the total combined cross-sectional of said slot openings;
- said plurality of radially extending slots extending radially outward from said axial chamber such that said slot openings are disposed beyond said proximal tubular end in the radial direction.
