Abstract
Pipe splitting apparatuses and systems including a replaceable blade, and methods therefor, are provided. In various examples, a pipe splitting apparatus includes an outer surface including a recess. A blade including a portion is disposed within the recess. A hardenable material is disposed within the recess. The hardenable material is configured to flow upon application to fill empty space within the recess and at least partially around the portion of the blade disposed within the recess. The hardenable material is further configured to harden after application to secure the portion of the blade within the recess and fix the blade to the pipe splitting apparatus.
