Abstract

An apparatus and method for mounting a device to a pipe. The apparatus is particularly useful for the installation and/or replacement of retrofit sensors and injectors to the piping of engine exhaust systems and emission control systems, and is designed to be used on pipes of different dimensions.

Claims

1. An apparatus for mounting a device to a pipe, the pipe having a curved wall having an outer surface and a hole through the pipe wall at a position in the pipe wall, the apparatus comprising:

(a) a gasket conformable to the outer surface of the pipe wall adjacent the pipe wall hole, and having a gasket hole complementary to the pipe wall hole,

(b) a mounting block,

having at least a part of one surface conformed to the outer surface of the pipe wall adjacent the pipe wall hole,

having integral therewith on that at least a part of the one surface a projection shaped to engage the pipe wall hole such that the mounting block can be placed on the pipe over the gasket with the projection engaging the pipe wall hole, and

having an aperture extending through the mounting block and projection, the end of the aperture furthest from the projection being adapted to receive the device,

such that, when the device is received onto the mounting block and the mounting block is placed on the pipe over the gasket with the projection engaging the hole in the pipe wall, there is a continuous open passage between the interior of the pipe and the device;

the mounting block further comprises integral therewith on that at least a part of the one surface a locating peg engageable with a second hole in the pipe wall and

(c) a fastener for securing the mounting block onto the pipe over the gasket such that the projection engages the pipe wall hole.

2. The apparatus of claim 1 further comprising at least two locating pegs.
