The pipe() method provides a filter for both the success and failure resolutions (of the AJAX request). If the original resolution is success, the pipe() filter either passes a truly successful response through; or, it changes the resolution, returning a new rejected promise. Then, if the original request was a failure, which would be truly unexpected in our API, the pipe() filter simply passes through a normalized API response structure....

Jquery official API page http://api.jquery.com/deferred.pipe/ (with examples)

Description: Utility method to filter and/or chain Deferreds.

The deferred.pipe() method returns a new promise that filters the status and values of a deferred through a function. The doneFilter and failFilter functions filter the original deferred's resolved / rejected status and values. As of jQuery 1.7, the method also accepts a progressFilter function to filter any calls to the original deferred's notify or notifyWith methods.
