A flow conditioning assembly comprising an integral elbow flow conditioner and a downstream flow conditioner. The elbow flow conditioner includes a pipe elbow with one or more flow conditioning elements. Each flow conditioning element includes one or more turning guides. Each turning guide is generally circular and radially spaced from one another and an inner surface of the elbow. Spaced vanes maintain the radial spacing of the turning guides. The vanes divide the radial space between the turning guides and pipe elbow into a plurality of flow channels that turn in generally the same direction as the inner surface of the pipe elbow. The downstream flow conditioner comprises a flow conditioning structure within a pipe element. The flow conditioning structure includes one or more flow guides of generally circular form radially spaced from one another and the pipe element. Spaced support vanes maintain the radial spacing of the flow guides.

A helix amplifier pipe fitting may include an elbow or straight pipe fitting including an expanded helix portion, a plurality of helix vanes at an angle of incidence to the incoming fluid flow to impart rotational velocity on the fluid. A helix amplifier may include a helix discharge amplifier having a tapered canister, a tapered helix portion including a plurality of helix vanes, and a tapered mixing chamber.

Provided are an inlet pipe including a curved portion having a curved shape, and a molding method thereof. In the molding method of the inlet pipe, that one part of the inlet pipe which includes a curved portion having a large curvature is molded by injection molding, and the other part of the inlet pipe except the one part molded by the injection molding is molded by blow molding.

The exhaust pipe comprises an inlet pipe, an outlet pipe and a bend portion arranged between the inlet pipe and the outlet pipe. The bend portion comprises an inlet bend and an outlet bend, wherein a central bend portion defines an intermediate section of inlet bend and outlet bend and wherein the inlet bend and the outlet bend each cover 50 percent of the total bend angle covered by the bend portion. The central bend portion comprises a diameter, which is smaller than a diameter of the inlet bend and of the outlet bend in a bending plane. In addition a bend radius R of the bend portion varies along the bend portion such that a bend radius of the inlet bend is larger than a bend radius of the outlet bend.

A method for geometrically designing a flow-conducting component, and a corresponding flow-conducting component, are provided. The flow-conducting includes a flow direction-changing surface arranged to change the direction of a flow by a certain angle from an inflow direction in a first section to an outflow direction in a second section, the flow direction-changing surface being formed corresponding to a contour of line segments having formed based on dependent triangulation between a bisector of the certain angle and sides of the first and/or second sections.
