Abstract: A piping in which a plastic tubular member is encased in wire mesh for use in fire sprinkler systems. The mesh substantially protects the tubular member from thermal deterioration. When deterioration does occur, it is generally in the form of pin holes which permit water to flow onto the mesh, cooling it, and preventing further heat transfer to the tubular member.
