摘要： The present disclosure generally pertains to methods and systems for reinforcing a plastic pipe bell. The disclosure may include arranging a sleeve fabricated from a heat shrinkable plastic around the plastic pipe bell, and shrinking the sleeve around the plastic pipe bell thereby forming a first interference fit between the sleeve and the plastic pipe bell. The disclosure may further include inserting a spigot into the plastic pipe bell and shrinking the sleeve around the spigot thereby and forming a second interference fit directly between the sleeve and the spigot.
