    Abstract: In a method of making a high-pressure accumulator pipe as composite pipe of steel for pressures of up to 1800 bar and above with high static strength and fatigue strength for fuel injection systems with common rail systems for internal combustion engines, a first inner pipe part is inserted into a second outer pipe part with little clearance, and the inner pipe part is connected to the outer pipe part gap-free and by interference fit through mechanical forming. The mechanical forming includes a rolling-in process, wherein the inner pipe part is subjected to a ductile expansion and the outer pipe part is subjected to an elastic expansion using an oversized rolling tool that is moved within the inner pipe part, and wherein a residual compressive stress adjusted to the operating pressure is applied to the inner pipe part after the forming process via the elastic resilience of the outer pipe part.

    Abstract: At least one embodiment generally relates to using an installation tool to pass an expansion mandrel through an elongated member to at least locally, radially expand at least a portion of the elongated member and achieve an interference fit with a radially expandable member located about an outer surface of the elongated member. In one embodiment, the elongated member is radially expanded over its entire length and may include a stepped feature so that only a portion of the elongated member achieves the interference fit with the radially expandable member. During the radial-expansion process, both the radially expandable member and the elongated member may be at the same or approximately the same temperature. Before the radial-expansion process, the radially expandable member may be assembled using press-fit techniques, shrink fit techniques, clearance fitting techniques, or combinations thereof.

    Abstract: A conduit for conveying hydrogen under conditions of high temperature and high pressure comprises a clad, seamless tubing having a substrate layer formed of a tough base material that includes iron, chromium, or nickel, or alloys thereof. The tubing further has a thin cladding or surface layer formed of an alloy including at least about 2-10% aluminum, combined with other materials that include at least one of iron and nickel and chromium, in an amount sufficient to make the surface layer capable of resisting hydrogen permeation. The conduit is formed by draw bonding a cladding tube in the substrate tube.

    Abstract: The invention relates to a method and apparatus for the production of double-walled hollow sections by means of internal high-pressure forming, a first hollow section being inserted into a second hollow section, after which the double-walled hollow section thus formed is subjected to high internal fluid pressure in such a way in an internal high-pressure forming die that the double-walled hollow section is expanded. During this process, an air gap is formed between the first, inner, hollow section and the second, outer, hollow section. In order to produce double-walled hollow sections with an air gap between the inner and the outer hollow section in a simple manner and with a reduced process time, the proposal is to position the inner hollow section in a defined manner in the outer hollow section during insertion, forming a gap, to introduce an intermediate layer between the inner hollow section and the outer hollow section, filling the gap, and, after expansion of the double-walled hollow section by internal high-pressure forming, to dissolve the intermediate layer out of the hollow section via an opening formed at least in one of the hollow sections, opening up the gap as an air gap.
