Abstract
An adjustable pipe connector for joining ends of lined pipe where corrosive or erosive gases, fluids or slurries may flow to provide a continuous corrosion barrier between the ends of adjacent pipe liners. The connector provides a telescoping arrangement of sleeves that may be adjusted in length to meet the needs of the pipes being welded. The connector also provides heat shielded weld points for welding to the pipe ends to ensure that the integrity of the pipe coatings is maintained.
