Abstract
A method of joining components of an exhaust system comprises obtaining a first pipe with a first end and inserting a second end of a second pipe within the first end of the first pipe to provide a length of overlapped first and second pipes. The method includes radially inwardly deforming the overlapped first and second pipes into pressed engagement with one another to define a pipe joint.
Claims23
A method of joining components of an exhaust system, the method comprising:
- obtaining a first pipe with a first end;
- obtaining a second pipe with a second end;
- inserting the second end of the second pipe within the first end of the first pipe to provide a length of overlapped first and second pipes including a first zone and a second zone;
- and
- radially inwardly deforming the overlapped first and second pipes into pressed engagement with one another at the second zone along the length of overlapped first and second pipes to define a pipe joint, wherein at the first zone of the length of overlapped first and second pipes, the second pipe includes an outer diameter greater than an inner diameter of the first pipe within the second zone.
2 more elements
An exhaust system comprising:
- a first pipe having a first end;
- and
- a second pipe having a second end positioned within the first end to provide a length of overlapped first and second pipes including a first zone and a second zone, wherein both of the first end and the second end are radially inwardly deformed into pressed engagement with one another at the second zone along the length of overlapped first and second pipes to define a pipe joint, wherein at the first zone of the length of overlapped first and second pipes, the second pipe includes an outer diameter greater than an inner diameter of the first pipe within the second zone.
