According to one embodiment, a flange joint for joining a first pipe to a second pipe includes an adapter coupled to the first pipe. The adapter includes a convex surface. The flange joint also includes a gasket with a first concave surface and a second convex surface. The first concave surface of the gasket is matingly engageable with the convex surface of the adapter. The second convex surface is matingly engageable with the second pipe. The gasket is supported on the first pipe. The flange joint further includes a clamp that includes a concave surface that is matingly engageable with the second pipe to secure the gasket to the adapter.

Spherical flange joint

A method for forming a conduit with a radial flange for forming part of a beaded coupling by: positioning a conduit blank in a forming die, wherein the forming die defines a radially extending recess; inserting a forming post in the conduit blank to define an annular space therebetween; inserting a flexible material in the annular space between the post and the conduit; placing a sleeve in a bearing relationship with the flexible material; compressing the flexible material between the post and the sleeve to force the flexible material against the conduit to expand the conduit outward into engagement with the radially extending recess in the forming die to form an annular flange; and releasing compression on the flexible material.

Elastomer formed beaded joint

A flexible tube system having an end section formed from an inner rigid tube and an outer shell, and the end section is joined to a central flexible portion having an inner decoupler tube, and an outer shell bridge is joined to the outer shell and the flexible central portion to define an insulation space.

Flexible automotive exhaust tube system

A spherical decoupler conduit for connecting misaligned components, and a method for making the same, where the spherical decoupler includes an inlet connection with a first spherical portion; an outer slider with a second spherical portion for pivotably mating with the first spherical portion and a tubular portion; an inner slider having a tubular portion in a telescoping relationship with the tubular portion of the outer slider and a third spherical portion; and an outlet connection with a fourth spherical portion for pivotably mating with the third spherical portion.

Gaseous diluter

A reductant decomposition reactor for use in exhaust systems is provided that includes a middle tube portion formed with a reductant injector mount, an inlet tube, an outlet tube and a mixer. The inlet tube is formed at a first end of the middle tube portion and the outlet tube is formed at a second end of the middle tube portion and both are configured to create a sealed connection to different portions of the exhaust system. The mixer fits between the middle tube portion and the outlet tube and is configured to decompose the reductant in an exhaust stream. The injector mount comprises a tube like section that connects at a first end to the middle tube portion and at a second end to an injector port of the injector mount, and is configured to reduce recirculation flow patterns in the reactor, create a high velocity flow at an inner surface of the injector mount and thereby reduce the formation of reductant deposits.

A vertical exhaust water trap assembly has an outer housing and an internal housing or exhaust tube defining an annular water collection spaced therebetween bypassing a central exhaust flow area.

Exhaust water trap

An exhaust water trap assembly has separated and spaced exhaust tubes, and a dome cap blocking entry of water to protect an upstream catalytic converter or soot filter. A first tube extends axially upwardly into a housing, and a second tube is spaced vertically thereabove. The dome cap on the top end of the first tube blocks exhaust flow axially upwardly therepast and blocks entry of water axially downwardly therepast.
