ABSTRACT:
A butt welded and lined flange connector allows the joining of pipe sections lined with a brittle material. Spacing and a sleeved liner at the weld end protects the liner during butt welding. A conventional flange face gasket is modified to protrude into the lined zone to perform a dual sealing function. Like conventional flanged joints, the modified gasket forms a seal sandwiched between the flange interface surfaces. However, departing from current practice, the single gasket also fills the gap and seals the liner edges, protecting the pipe sections from the flowing materials. The invention avoids separate putty-like or elastomeric liner seals as well as exotic liner surface configurations. The present invention is expected to be tolerant of severe conditions and cost effective in many applications.
