Abstract
A diffuser pipe for a gas turbine engine comprises a hollow pipe body including a first end, a second end fluidly connected to the first end, and at least one flattened area proximate to the second end. A ring is connected to the second end. The ring is an outlet of the diffuser pipe. At least one stiffener is disposed on the at least one flattened area. The ring and the at least one stiffener reduce vibratory stresses at the second end of the pipe body. A method of manufacturing a diffuser pipe of a gas turbine engine is also presented.

A diffuser pipe for a gas turbine engine, the diffuser pipe comprising:
- a hollow pipe body including:
- a first end;
- a second end fluidly connected to the first end;
- and
- at least one flattened area proximate to the second end;
- a ring connected to the second end, the ring being an outlet of the diffuser pipe;
- and
- at least one stiffener disposed on the at least one flattened area, the ring and the at least one stiffener reducing vibratory stresses at the second end of the pipe body.
A method of manufacturing a diffuser pipe of a gas turbine engine, the method comprising:
- forming a hollow diffuser pipe body from at least one sheet metal;
- adding a raised structure on a flat portion of the diffuser pipe body near an end of the diffuser pipe body;
- and
- connecting a unitary formed ring to the end of the diffuser pipe body.
