    Abstract: A thick-walled, seamless, rigid non-porous conduit (Y) having a substantially uniform wall thikkness which is not less than about 0.5 percent of the outside diameter consisting essentially of an oriented crystalline thermoplastic polymer characterized by a structure comprised of radially compressed discrete, platelet-like spherulitic crystalline aggregates (A!) and having a combination of good ultimate tensile strength and low temperature tensile impact strength. The conduit is fabricated by solid state hydrostatic extrusion of a substantially non-oriented semi-crystalline thermoplastic polymer preform (X) which may contain up to about60 weight percent filler. The polymer is substantially simultaneously elongated in both circumferential and axial directions by compressive forces with the circumferential elongation being at least 100 percent. The apparatus used to produce the product is a hydrostatic extrusion press which includes an annular orifice in which the thermoplastic polymer is elongated substantially simultaneously circumferentially and axially with the circumferential elongation being at least 100 percent. Means for maintaining the rigidity of tooling and the hydrostatic extrusion fluid pressure while providing a film of the fluid on the preform for lubricity are provided in the apparatus. A sheet (F) substantially uniform in thickness and having substantially the microstructure and properties of the conduit and excellent drawability may be made from the conduit by slitting and heat deformation. Articles of manufacture may be made by solid state deformation processing of the conduit or the sheet, such as vacuum drawing.

    Abstract: A WIRE FIBER REINFORCED PLASTIC COMPOSITE IS FORMED FROM A STYRENE TYPE RESIN SUCH AS POLYSTYRENE OR ACRYLONITRILE-BUTADIENE-STYRENE (ABS) RESIN AND THIN FERROUS METAL WIRES OR FIBERS. THE FERROUS WIRES OF FIBERS ARE PREVENTED FROM CORRODING AT THE SURFACE OF THE PLASTIC BY THE PROVISION OF EITHER SACRIFICIAL WIRES FORMED T METAL SUCH AS ZINC, OR ALTERNATIVELY, FERROUS WIRES COATED WITH A SACRIFICIAL METAL SUCH AS ZINC. THE FERROUS WIRES ARE PREVENTED FROM CORRODING IN THE INTERIOR OF THE COMPOSITE BY A TIGHT ADHERENT BOND FORMED BETWEEN THE SURFACE OF THE FERROUS WIRES AND THE STYRENE OR ABS RESIN BY A BINDER OF ABS RESIN BETWEEN THE FERROUS METAL AND THE PLASTIC MATRIX. THE TIGHT BONDING OF THE FERROUS WIRES

    TO THE MATRIX PLASTIC ALSO ENABLES A VERY SMOOTH SURFACE FINISH TO BE ATTAINED UPON THE FINISHED PLASTIC ARTICLES. IN SOME CASES THE SACRIFICIAL METAL MAY NOT BE INCLUDED IN THE COMPOSITE.

    Abstract: A prefabricated deformable laminated insulation panel for use in fluid conduit construction and/or an insulated pipeline system. The laminated panel comprises an outer skin, truncated prisms of insulating material having one base adhered to the outer skin and a relatively lighter inner skin adhered to the sides and the other base of the truncated prisms and to the outer skin, and means for spacing the insulation panel from and supporting the panel on the insulated pipe. The insulation panels are deformable about various shapes and sizes of pipe to provide an efficient insulation structure.
